The road to becoming a Cisco Certified Design Expert (CCDE) is neither short nor straightforward. It’s a journey that demands years of dedication, an unyielding drive for knowledge, and the willingness to evolve at every step. From the moment I began my career as a network engineer, I knew that technical expertise was just the foundation. The real challenge would come when I had to extend my vision beyond troubleshooting and maintenance and think strategically about how networks could help businesses achieve their goals.
For years, my role was confined to solving day-to-day network issues. I was immersed in the technical side of things, managing the connectivity of systems, diagnosing problems, and ensuring that everything ran smoothly. However, I soon realized that my career was at a crossroads. If I wanted to reach the pinnacle of network engineering, I would have to expand my horizons. The answer came in the form of a new opportunity at Cisco as a Systems Engineer. This decision marked the beginning of my transformation.
The transition was not easy. Moving from the narrow focus of network engineering to the expansive role of a Systems Engineer required me to rethink my entire approach to networks. Suddenly, the technical aspects that I had mastered for years had to be viewed through a different lens. As a Systems Engineer, I was not merely expected to fix problems or optimize performance. I had to consider the broader business impact of my decisions. How would the network support the company’s growth? What was the long-term strategy, and how could the network be designed to scale with it? These were questions I had never had to ask myself before.
What struck me most about this shift was that it was not simply about learning new technical skills. It was about developing a mindset that understood how technology could drive business value. This transition required me to step outside the comfort of technical troubleshooting and immerse myself in business-centric thinking. In many ways, this role forced me to take on the responsibility of designing solutions that made sense from both a technical and a business perspective, which was far more complex than anything I had encountered before.
The leap from network engineering to a systems engineering position was a pivotal moment in my career. I had to let go of the notion that being a technical expert was enough. I had to learn how to merge business and technology into something that could truly make an impact. And it was this mindset that would later be essential as I moved towards earning my CCDE certification. It was a reminder that growth in the tech industry isn’t just about deepening your technical knowledge but about understanding the bigger picture and the role technology plays in achieving business objectives.
The Challenges of Transitioning to a Business-Oriented Role
At first, the shift from being an engineer who primarily focused on technical troubleshooting to a Systems Engineer who had to evaluate networks through a business-centric lens felt daunting. In the beginning, I struggled with understanding how my technical skills could translate into real business solutions. After all, the two worlds seemed so far apart. I had spent so many years diving deep into the technical side of networking that the idea of applying those skills to broader business goals felt unfamiliar and intimidating.
This period of adjustment was filled with moments of self-doubt. As a technical engineer, I had always been confident in my ability to solve problems, but in the new role, the problems weren’t just about fixing a device or optimizing network speed. They were about ensuring that the network infrastructure could support the larger vision of the business. The more I reflected on this, the more I realized that while the technical aspect was crucial, it was only one piece of a much larger puzzle.
In my new role, I found myself sitting in meetings with business leaders, discussing the future of the company, its goals, and how technology could help achieve those goals. I was no longer just the guy in the background who made sure that everything was working as expected. I was expected to be part of the decision-making process. I had to consider scalability, cost-effectiveness, and flexibility in my network designs. More importantly, I had to understand the strategic direction of the company to ensure that the solutions I proposed aligned with the business’s long-term vision.
This challenge was compounded by the fact that I was working with customers whose needs were not always easy to understand. It wasn’t just about providing them with a network that worked; it was about providing them with a network that would give them a competitive advantage, improve their operations, and help them grow. At first, this felt overwhelming. It wasn’t enough to be a technical expert; I had to become an expert in business as well.
The struggle during this time was real. I had to train myself to think more like a strategist and less like an engineer. I had to ask questions I had never asked before: What are the business’s pain points? What do they need today, and how do we ensure that the network can scale tomorrow? These questions were not a natural part of my previous role, but they became the cornerstone of my new responsibility. The more I immersed myself in this new approach, the more I began to understand the profound impact of networks on business operations. I realized that the best network designs were not just about having the fastest or most reliable systems. They were about creating an infrastructure that could evolve with the needs of the business, one that could drive innovation and foster growth.
While the technical aspects were still essential, this role taught me that designing networks is a collaborative process that requires both technical and business insights. It was this realization that ultimately set me on the path toward pursuing the CCDE, as I understood that true mastery in networking wasn’t just about understanding how networks work but about understanding how they work within the larger context of the business.
The Role of Mentorship and Training at Cisco
One of the most valuable aspects of my time at Cisco was the mentorship and training programs available to employees. Cisco places a strong emphasis on continuous learning, and I was fortunate enough to have access to a vast array of resources. Whether it was internal workshops, certification programs, or one-on-one mentoring, there was always an opportunity to learn and grow. It was during this period that I began to see the clear path forward to the CCDE certification.
Cisco’s mentorship program, in particular, was instrumental in shaping my career. I had the privilege of working alongside seasoned professionals who had a wealth of knowledge and experience in network design. Their insights into the industry were invaluable, and their willingness to share their expertise helped me gain a deeper understanding of the complexities of network design. What I found particularly helpful was the approach they took in mentoring. They didn’t just tell me what to do; they encouraged me to think critically and creatively about network solutions.

These guides provided me with the theoretical foundation I needed to prepare for the more advanced CCDE certification. Studying these guides gave me a clearer understanding of enterprise-level network architecture and design principles. The more I read, the more I realized how interconnected the various aspects of network design were, from ensuring that networks were scalable and secure to ensuring that they aligned with the broader business goals.
While mentorship and training were essential, what truly propelled me forward was my ability to apply the knowledge I gained in real-time. I was able to work on projects that required me to design complex networks, and with each project, I gained a greater understanding of the challenges that come with designing large-scale network infrastructures. These experiences provided the practical knowledge and confidence I needed to pursue the CCDE certification.
The Road to the CCDE Certification
By the time I began preparing for the CCDE exam, I had already accumulated years of hands-on experience. However, the certification was no easy feat. The CCDE exam is known for its complexity and the depth of knowledge required to succeed. It is a test of both technical expertise and strategic thinking, challenging individuals to design and implement enterprise-level networks that meet the needs of businesses in various industries.
As I began my preparations, I quickly realized that the knowledge I had gained from years of technical work and systems engineering was just the beginning. The CCDE exam required a much broader understanding of networking principles, and it pushed me to think about networks in new ways. It was not enough to simply know how to configure a router or optimize a network; I had to understand the big picture—how different technologies, business needs, and scalability concerns intersected to create a cohesive network design.
Preparing for the CCDE exam required a focused effort. I dedicated months to studying the CCDA and ARCH materials, supplemented by hands-on practice and case studies. The exam was as much about problem-solving as it was about knowledge, and I had to constantly think critically about how I would address various network design challenges. It wasn’t just about being technically proficient; it was about being able to envision the future of a network and ensure that it would continue to support the evolving needs of a business.

When I first started preparing for the Cisco Certified Design Expert (CCDE) exam, I thought it would be a straightforward process—read the guides, understand the concepts, and apply them. However, I quickly discovered that preparing for a certification of this caliber was far more than just memorizing theory. It was about cultivating a mindset that would allow me to transform complex knowledge into actionable strategies for network design. The journey to CCDE was a lesson in personal and professional growth, one that tested my capabilities and pushed me to grow beyond my technical expertise.
At the time, I was going through several life transitions. The pandemic had forced me to work from home, and I had recently experienced a significant job change due to immigration. While these shifts were challenging, they also presented a unique opportunity. I had the time and space to dedicate myself to studying full-time for the CCDE exam. It was as if the world had aligned to offer me a chance to focus solely on this ambitious goal. I knew that this time would be invaluable, and I was determined to make the most of it.
The transition from simply being a network engineer to becoming a network architect meant that my approach to studying needed to evolve. I could no longer rely on the same methods I had used in the past. I had to dive deeper into understanding not just how networks operate but why they function in specific ways. What made the CCDE exam so challenging was that it didn’t simply test your ability to memorize facts or configure networks; it tested your ability to think strategically about network design, integrating business needs with technical solutions. This shift in focus meant that I had to restructure my study methods and adopt a new way of thinking about both learning and applying knowledge.
With my circumstances changing, I knew I needed to be strategic. The process of preparing for the CCDE exam became a transformative experience, shaping not only my professional skills but my personal mindset as well. The initial stages of this journey involved assessing my strengths and weaknesses and designing a study plan that would balance both the theoretical and practical elements required for success. As I moved forward, I learned that this approach would ultimately be my path to success.
Building a Strong Theoretical Foundation
The first step in my preparation involved developing a strong theoretical foundation. For a certification as comprehensive as the CCDE, understanding the theory behind network design was essential. I focused primarily on the official CCDEv2 and CCDE 400-007 guides. These materials provided the knowledge I needed to begin mastering the core principles of network architecture. Reading these guides was not just about acquiring knowledge; it was about understanding the broader concepts that underpinned effective network design.
What I quickly realized, however, was that merely reading the guides wasn’t enough. The CCDE exam requires a deep understanding of advanced concepts like network scalability, redundancy, security, and performance optimization. These are not simple topics to grasp—they require a nuanced understanding of how each component interacts within a larger network. For example, learning about the intricacies of QoS (Quality of Service) and its impact on network design was a challenge, but it was essential for answering the types of questions I would encounter on the exam. It wasn’t enough to know that QoS existed; I had to understand when and why it should be applied in different scenarios to ensure optimal network performance.
To internalize these concepts, I had to read and reread sections of the guides until I could fully grasp each concept. I found that breaking down the material into smaller, digestible parts helped me focus and retain the information. I didn’t simply read for the sake of completing a section—I read with purpose, actively questioning how the concepts applied to real-world network challenges. This allowed me to make the connection between theory and practice, an essential skill for anyone looking to earn a CCDE.
Taking notes was another crucial aspect of my theoretical preparation. Writing things down helped me engage with the material on a deeper level. As I wrote detailed notes, I found myself thinking critically about the material I had just learned. I would pause to reflect on how I could apply each concept to various design scenarios. This reflection made it easier to recall information during practice tests and, eventually, the actual exam. The process of writing not only solidified the information in my mind but also allowed me to organize complex concepts in a way that was easier to understand and apply.
This phase of studying was rigorous but rewarding. It involved pushing past the basics and diving into the layers of complexity that define network architecture. The knowledge I gained from these materials wasn’t just academic—it was the foundation upon which I would build my career as a network architect.
Practicing with Real-World Scenarios
While theory provided the knowledge I needed, it was practice that truly honed my skills. For network architects, the ability to apply theoretical knowledge in real-world scenarios is essential, and the CCDE exam reflects this reality. Reading the guides and memorizing concepts would never have been enough. To succeed, I needed to practice applying these concepts in dynamic, real-world network environments.
One of the best resources I found for hands-on practice was the CCDEv3 Practice Labs book. This book allowed me to simulate various network scenarios, mimicking the types of challenges I would face as a network architect. The ability to experiment with these scenarios gave me a taste of the complexities and decision-making required in network design. It was one thing to know how to configure a network; it was another to understand the strategic choices behind those configurations.
Through these practice labs, I gained experience with things like traffic engineering, network segmentation, and fault tolerance—topics that are critical to designing networks at scale. But even more importantly, I learned how to think through the challenges and prioritize the needs of a business while addressing the technical requirements of a network. Each scenario required me to balance performance, scalability, cost, and security—all essential elements in any network design. It was this process of evaluating and selecting the best solutions that helped me prepare for the kinds of questions I would face on the CCDE exam.
The hands-on practice wasn’t limited to just reading a book and performing the exercises. I sought out additional practice through online simulations and labs. These platforms provided me with even more opportunities to engage with real-world network issues, further cementing the skills I had acquired. The ability to simulate large-scale networks, apply changes, and troubleshoot issues in real-time gave me a comprehensive understanding of network design principles. As I moved through these exercises, I began to see how theory and practice were intertwined—how the choices I made in the simulated environments directly affected the outcome of the network’s performance.
By practicing with real-world scenarios, I was able to translate the theoretical concepts I had learned into practical expertise. This experience was invaluable, not only for preparing for the exam but for my career as a network architect. The hands-on practice gave me the confidence to make decisions that weren’t just theoretically sound but also strategically advantageous for the businesses I would design networks for in the future.
The Importance of Structure and Consistency
As my study journey continued, I realized that maintaining a structured approach was crucial for staying on track. With so much material to cover, the temptation to jump between topics or to focus on areas of personal interest was strong, but this lack of organization would have led to frustration and wasted time. To keep myself grounded, I developed a detailed study plan.
I meticulously tracked my progress using a personalized spreadsheet, breaking down the study material into specific sections. This allowed me to focus on one area at a time, ensuring I covered everything needed for the exam without feeling overwhelmed. Having a structured plan also made it easier to see how much progress I had made. This visual representation of my study journey helped me stay motivated and gave me a sense of accomplishment as I checked off each completed section.
Along with the structure, consistency was key. It wasn’t enough to study intensely for a few days and then take a break. To truly master the material, I needed to study consistently over a long period. I made sure to dedicate a set amount of time each day to studying, even when life outside of studying became chaotic. This consistency paid off in the long run, as it allowed me to gradually internalize the material rather than cramming it all at once.
The systematic approach I followed helped reduce the stress that often accompanies exam preparation. By breaking the material into manageable sections and tracking my progress, I was able to stay organized and avoid feeling overwhelmed. I also created dedicated time for revision and practice exams. These revisions were essential for reinforcing my knowledge and ensuring that I was fully prepared when exam day arrived.
Ultimately, the combination of structured learning, consistent study habits, and hands-on practice led me to a place of readiness. Preparing for the CCDE was more than just passing an exam—it was about developing a comprehensive understanding of network design that would serve me for years to come. By staying disciplined and organized, I was able to approach the exam with confidence and clarity, ready to demonstrate not only my technical knowledge but also my ability to think strategically about network architecture.
The Crucial Role of Real-World Experience in Network Design
When it comes to preparing for an advanced certification like the Cisco Certified Design Expert (CCDE), it becomes abundantly clear that there’s no substitute for hands-on experience. As much as theory and books lay the groundwork, it is through real-world projects that the deepest lessons are learned. This was especially true for me during my preparation for the CCDE. The projects I worked on as a network architect were invaluable in helping me refine my skills and understand the nuances of network design in a practical setting.
I had the privilege of working on large-scale municipal networks, where the complexity of the designs was both daunting and exhilarating. These projects tested my technical skills and demanded that I push the boundaries of what I knew about networking. Unlike theoretical exercises, these real-world networks had to meet specific, real-time requirements. They had to operate efficiently in the face of countless variables like traffic loads, security risks, scalability, and fault tolerance. This gave me the opportunity to apply the principles I had studied to real, dynamic situations.
One of the most important things I learned through these projects was the importance of collaboration. Networks aren’t built in isolation—they are the product of cross-functional teamwork. In municipal network projects, I worked closely with a diverse range of professionals: from software developers to business strategists to operations managers. This collaboration was crucial in ensuring that the network design not only met technical specifications but also aligned with the broader business objectives of the project. It taught me the importance of communication and coordination across departments, and how critical it is to understand the needs of every stakeholder when designing a network.
The hands-on experience in these projects also forced me to solve problems on the fly. In a network design project, challenges arise unexpectedly, and it is often up to the architect to make critical decisions under pressure. These situations honed my problem-solving skills, as I had to weigh different solutions, think about long-term consequences, and make the right call quickly. In doing so, I gained an appreciation for the complexity of designing networks at scale and the level of expertise required to succeed. The lessons learned from these projects were invaluable and directly translated into my exam preparation.
Real-world experience shaped my approach to the CCDE exam in ways that theory alone could not. It provided me with the perspective I needed to see how theoretical concepts applied in practice and highlighted the importance of making decisions based on a comprehensive understanding of the bigger picture. As I continued to work on complex network design projects, I became more confident in my ability to handle the challenges of the CCDE exam and, ultimately, the challenges of real-world network architecture.
Simulating Real-World Scenarios for Exam Preparation
When preparing for an exam as comprehensive and challenging as the CCDE, it quickly became clear to me that simply reading textbooks and guides would not suffice. To truly prepare, I had to immerse myself in real-world scenarios, simulating the conditions and challenges I would face on the exam. This simulation aspect was a key part of my preparation process, as it allowed me to practice problem-solving and strategic thinking under conditions that mimicked the exam environment.
To achieve this, I turned to the CCDEv3 Practice Labs, a resource designed to provide realistic, hands-on practice for candidates preparing for the exam. I made it a point to simulate exam conditions as closely as possible. I timed myself during the practice labs, carefully following the same guidelines and time constraints that I would face during the actual exam. This created an environment that replicated the pressure and intensity of the real exam, forcing me to think quickly and efficiently.
The scenarios in the practice labs weren’t just theoretical; they were based on real-world problems that network architects frequently face. These scenarios required me to design solutions that were not only technically sound but also strategically aligned with business needs. I found that the more I practiced, the more adept I became at identifying the core issues in each scenario. This process taught me how to approach complex network designs with a clear, focused strategy, enabling me to break down each problem into manageable components.
One of the most critical aspects of the CCDE exam is the focus on problem-solving, decision-making, and strategic thinking.

It became clear that real-world experience, combined with simulated practice, was the key to mastering the CCDE exam and excelling in the field of network architecture.
Leveraging RFCs to Deepen Knowledge
Another critical component of my CCDE preparation was learning how to leverage RFCs (Request for Comments) and their detailed solutions. RFCs are the foundational documents that define internet protocols and network standards, and they form the backbone of much of the knowledge required for the CCDE exam. Having an in-depth understanding of RFCs and the ability to reference them quickly became an essential skill as I prepared for the exam.
As I studied for the CCDE, I realized that understanding the theoretical aspects of networking wasn’t enough. To truly excel in the exam, I had to master the ability to access and apply RFCs on the fly. This skill was not just about memorizing the numbers and titles of RFCs, but about understanding their content in a way that allowed me to solve complex design problems efficiently. RFCs are often dense, technical documents, but they are critical for understanding the design principles behind protocols and technologies like BGP, OSPF, and MPLS.
During my preparation, I made a point to regularly review RFCs related to the topics covered in the CCDE exam. Whenever I encountered a question or scenario that required me to make a design decision, I would reference the relevant RFCs to ensure that my solution was in line with industry standards. This process helped me not only to memorize key details but also to deepen my understanding of the protocols and their applications in network design.
One of the most important lessons I learned through this process was how to quickly extract relevant information from an RFC during the exam. The CCDE exam is known for its complexity, and there are often situations where candidates need to consult RFCs to answer questions or solve design problems. In the exam, there is limited time, so being able to quickly identify the most pertinent details in an RFC and apply them to a given scenario is a skill that sets successful candidates apart from others.
Through repeated exposure to RFCs and their detailed solutions, I was able to strengthen my ability to think critically about network design decisions. I learned to recognize the nuances in each RFC and understand how different protocols interacted with one another. The more I incorporated RFCs into my study routine, the more confident I became in my ability to reference them efficiently during the exam. This skill not only helped me on the CCDE but also proved invaluable in my career as a network architect.
Leveraging RFCs in my study process gave me the confidence to approach the CCDE exam with the knowledge that I could rely on these standards to guide my decision-making.

The CCDE Exam: A Journey into Architectural Thinking
As I walked into the exam room for the Cisco Certified Design Expert (CCDE) exam, I realized that this moment was the culmination of a long, challenging journey. Unlike any other certification I had pursued before, the CCDE was not just about proving technical expertise in a particular area—it was about demonstrating the ability to think strategically and design complex network architectures. I had taken various certifications in my career, including the rigorous CCIE, but the CCDE was fundamentally different. The focus wasn’t on mastering a single technology but on understanding the bigger picture—network architecture as a holistic system.
What truly set the CCDE exam apart was its emphasis on architectural thinking. As a network architect, you are expected to integrate multiple technologies, solutions, and business needs into a cohesive design that will serve an organization’s long-term goals. The CCDE exam requires you to think like an architect—not just an engineer. This was the mindset shift I had to make in my preparations. While other certifications may test your knowledge of how a protocol functions or how to configure a device, the CCDE challenges you to look at a network as a whole and determine how various technologies can be combined to meet a specific business objective.
During my preparation, I realized that the most important skill I needed to master wasn’t necessarily technical depth but the ability to synthesize information from multiple sources and design a comprehensive solution. This was a shift in thinking, moving away from simply fixing issues or optimizing performance and toward creating systems that align with broader business goals. It was this shift that became the foundation of my strategy for approaching the CCDE exam.
I developed a detailed exam strategy that would guide me through the complex scenarios I would encounter. The first step was to read the scenario multiple times. At first glance, the exam questions can feel overwhelming, filled with technical jargon and complex requirements. It’s easy to get lost in the details, but the key to success was to first understand the big picture. I would carefully read through the scenario, identifying the high-level requirements and objectives. Then, I would dive deeper, highlighting the key information that would inform my solution. This step allowed me to map out the requirements and organize my thoughts before jumping into the design process.
Understanding that the CCDE exam was about solving problems from an architectural perspective rather than focusing on specific technologies helped me approach the questions with more confidence. I wasn’t just memorizing facts—I was using the knowledge I had accumulated over the years to analyze problems and come up with thoughtful solutions that would stand the test of time. This ability to think architecturally, integrating various network components into a cohesive solution, was the key to success in the exam.
Time Management and Pressure: Lessons from Real-World Experience
One of the most challenging aspects of the CCDE exam was managing the pressure and time constraints. The exam consisted of multiple scenarios, each with a two-hour time limit. As the clock ticked down, I found myself navigating through complex questions with large amounts of information to digest. The pressure to perform within such a limited time frame made the experience intense and mentally demanding.
In the real world, network architects often face tight deadlines, and the ability to make informed decisions under pressure is crucial. During my years of working on complex projects as a network consultant, I had developed the ability to manage time and pressure effectively. These skills came in handy during the exam, as I was able to remain calm and focused despite the time constraints.
The CCDE exam was more than just a test of technical knowledge—it was a test of how well you could manage stress and make decisions quickly. Each scenario presented a unique challenge, and I had to prioritize the most critical aspects of the design while ensuring that I wasn’t overlooking important details. The time limit made it impossible to second-guess every decision, so I learned to trust my instincts and the knowledge I had gained over the years.
For some of the questions, I had to rely heavily on my problem-solving skills. In real-world network design, problems rarely come with clear-cut solutions. As an architect, you often have to consider multiple variables and weigh the pros and cons of different approaches. This ability to analyze and solve complex problems was something I had honed over the years through hands-on experience. During the exam, I applied this same problem-solving approach, breaking down each scenario into manageable parts and focusing on the most important aspects first.
In other instances, when I felt unsure about a particular solution, I leaned on documentation and process elimination. One of the most important lessons I had learned throughout my career was how to leverage resources efficiently. During the exam, when I was uncertain, I would reference the study materials and consult the available information to confirm my assumptions. This helped me stay on track and avoid making rash decisions that could have led to errors.
Ultimately, the CCDE exam wasn’t just about technical knowledge—it was about the ability to perform under pressure and make decisions with confidence. My years of experience managing complex projects in high-stakes environments had prepared me well for this aspect of the exam.

As I reflect on the process, I realize that the exam was not just a test of my ability to design networks; it was a test of my ability to think critically, solve problems, and make decisions that align with the broader goals of a business. These skills, which I honed during my preparations, are what set great network architects apart from the rest.
While the CCDE exam marked the end of one chapter in my career, it also opened the door to new opportunities and challenges. The certification was just the beginning of my journey as a network architect, and I am excited to continue applying the knowledge and skills I gained through this experience. The learning never stops in this field, and I look forward to the next chapter, where I will continue to evolve as a professional, stay ahead of emerging technologies, and create network solutions that drive business success.
Conclusion
Reflecting on my journey to becoming a Cisco Certified Design Expert (CCDE), I am reminded that the path of a network architect is not a destination but a continuous journey. Earning the CCDE certification was an important milestone, but it is just the beginning of a lifelong commitment to learning, evolving, and adapting to new challenges and technologies. The exam itself was not simply a test of technical knowledge—it was a test of how well I could integrate my experiences, skills, and insights to design networks that align with business goals and anticipate future needs.
The preparation for the CCDE and the exam itself have taught me the importance of strategic thinking, problem-solving, and decision-making under pressure. Through hands-on experience and the systematic application of knowledge, I gained not just technical proficiency but also the mindset required to navigate complex design challenges. These lessons have reshaped the way I approach every project, emphasizing the need to think about networks in a holistic way that balances technical requirements with business priorities.
While the certification represents an achievement, it also reminds me that the landscape of network architecture is always changing. Technology evolves, businesses grow, and new challenges emerge. As network architects, we must remain flexible and open to learning new concepts, adapting to emerging trends, and refining our strategies to meet the evolving demands of the industry. The journey is ongoing, and the learning continues every day.
Looking ahead, I am excited to continue this journey, leveraging the lessons learned from the CCDE exam to navigate the challenges of modern network architecture. The journey may be long and challenging, but with each step, I am building a foundation for success in a field that is as dynamic as the networks we design. The CCDE was not an end but a beginning—a stepping stone toward mastering the craft of network architecture and continuing to evolve as a professional.
