Many managed service providers, corporate IT departments, help desk operations, and technology retail environments specifically require or strongly prefer A+ certification for their entry-level technical support positions. For professionals beginning their IT careers, the A+ certification provides a structured and recognized path into the field that opens doors to opportunities that might otherwise be inaccessible without prior professional experience.
Core 2 Exam Structure
The 220-1102 Core 2 examination consists of a maximum of ninety questions that candidates must complete within ninety minutes. The exam is delivered through Pearson VUE testing centers and through online proctored delivery for candidates who meet the technical and environmental requirements for remote testing. Question types include multiple choice with single correct answers, multiple choice with multiple correct answers, and performance-based questions that present candidates with simulated environments where they must complete specific tasks to demonstrate practical knowledge rather than simply selecting from answer options.
The passing score for the 220-1102 examination is seven hundred and fifty on a scale of one hundred to nine hundred. CompTIA uses a scaled scoring model that accounts for variations in question difficulty across different exam versions, ensuring that the passing standard remains consistent regardless of which specific set of questions a candidate receives. Performance-based questions appear at the beginning of the examination and are weighted more heavily than standard multiple-choice questions, which means candidates who skip these questions or answer them carelessly risk significantly impacting their overall score even if they perform well on the remaining multiple-choice content.
Operating Systems Domain Coverage
The operating systems domain is the largest single content area in the 220-1102 examination, accounting for approximately thirty-one percent of the total exam content according to the official CompTIA exam objectives document. This domain covers the installation, configuration, and management of Windows operating systems, which remain the dominant platform in enterprise IT environments and therefore represent the most frequently encountered operating system for IT support professionals. Candidates must be familiar with the features, editions, and system requirements of supported Windows versions, including differences between home and professional editions that affect their suitability for business deployment.
Beyond installation and basic configuration, the operating systems domain tests knowledge of Windows administrative tools that IT support professionals use daily. The Microsoft Management Console and its snap-ins, Task Manager, Event Viewer, Registry Editor, Group Policy Editor, and the command-line environment with its essential commands are all areas where the examination expects practical familiarity. Candidates must understand how to use these tools to diagnose system issues, manage user accounts and permissions, configure system settings, and perform routine maintenance tasks. The domain also covers macOS and Linux operating systems at a foundational level, reflecting the reality that support professionals increasingly encounter these platforms in mixed-environment organizations.
Security Fundamentals Tested
Security content accounts for approximately twenty-five percent of the 220-1102 examination and covers the essential security concepts and practices that IT support professionals must apply in their daily work. This domain begins with foundational security concepts including the principles of least privilege, defense in depth, and the confidentiality, integrity, and availability triad that frames how security professionals think about protecting information and systems. Candidates must understand how these principles translate into practical security controls and why following them consistently is important even in routine support scenarios.
Malware represents a significant portion of the security domain, and candidates must be familiar with the major categories of malicious software including viruses, worms, trojans, ransomware, spyware, adware, and rootkits. For each type, understanding how it spreads, what damage it causes, and how it is detected and removed is essential examination knowledge. The process of removing malware from an infected system follows a specific sequence that the examination tests explicitly, including identifying and quarantining the infected system, disabling system restore, remediating the infection, updating security software, enabling system restore, and scheduling future scans. Candidates who memorize this sequence and understand the reasoning behind each step are well prepared for malware-related questions.
Windows Installation Procedures
Installing Windows operating systems correctly is a foundational competency for IT support professionals, and the examination tests this knowledge across several scenarios that technicians regularly encounter in practice. Candidates must understand the difference between clean installations, which wipe the existing system and install a fresh copy of the operating system, and upgrade installations, which preserve existing applications, settings, and user data while replacing the operating system version. They must also know how to perform in-place repairs of Windows installations that have become corrupted or unstable without losing user data.
Unattended installations using answer files allow organizations to deploy Windows across large numbers of systems consistently and efficiently without requiring a technician to manually respond to installation prompts on each machine. The examination covers the concept of unattended installation and the role of answer files in automating the installation process, though it does not test the detailed syntax of answer file creation at the depth required for a Windows deployment specialist role. Disk partitioning during installation is another tested area, including the difference between MBR and GPT partition table formats, when each is appropriate, and how the presence of existing partitions affects installation options and the preservation of existing data.
Active Directory and Account Management
Active Directory is the directory service used in Windows domain environments to centrally manage user accounts, computers, and access to network resources. IT support professionals who work in business environments encounter Active Directory constantly, and the 220-1102 examination tests foundational knowledge of how to work within an Active Directory environment to perform common support tasks. Candidates must understand the relationship between domains, organizational units, and group policies, and how these structures are used to organize and manage users and computers in enterprise environments.
Account management tasks covered in the examination include creating and disabling user accounts, resetting passwords, managing group memberships, and applying appropriate account lockout and password policies. The distinction between local user accounts, which exist only on a single computer, and domain user accounts, which are managed centrally in Active Directory and can be used to log into any domain-joined computer, is a fundamental concept that the examination tests in multiple contexts. Candidates must also understand how account lockout policies work, why they are important for security, and how to unlock accounts that have been locked due to repeated failed login attempts, which is one of the most common help desk tasks in any organization using Active Directory.
Virtualization and Cloud Concepts
Virtualization and cloud computing have become standard components of modern IT infrastructure, and the 220-1102 examination includes content that reflects the practical knowledge IT support professionals need in environments that use these technologies. The examination covers the fundamental concept of virtualization, which allows multiple virtual machines to run simultaneously on a single physical host by abstracting the hardware resources of the host and presenting each virtual machine with its own simulated hardware environment. Candidates must understand the roles of the hypervisor, which manages the allocation of physical resources to virtual machines, and the difference between Type 1 hypervisors that run directly on hardware and Type 2 hypervisors that run as applications within a host operating system.
Cloud computing concepts tested on the examination include the major cloud service models of Infrastructure as a Service, Platform as a Service, and Software as a Service, each of which provides different levels of managed infrastructure and places different responsibilities on the customer organization. The deployment models of public cloud, private cloud, hybrid cloud, and community cloud are also covered, along with the practical implications of each for data security, compliance, and cost management. File synchronization services, virtual desktop infrastructure, and cloud-based applications are specific technologies that the examination references because IT support professionals regularly assist users who work with these technologies in their daily work.
Operational Procedures Domain
Operational procedures represent approximately twenty-two percent of the 220-1102 examination content and cover the professional practices and safety procedures that distinguish competent IT support professionals from those who simply possess technical knowledge. Documentation is a foundational operational practice that the examination addresses extensively, including the types of documentation that IT departments maintain, such as network diagrams, asset inventories, knowledge base articles, and change management records, and why keeping this documentation accurate and current is important for organizational efficiency and continuity.
Change management is a structured process for controlling modifications to IT systems and infrastructure that minimizes the risk of unintended disruptions to operations. The examination covers the basic components of a change management process, including the submission of change requests, risk assessment, approval workflows, implementation planning, testing, and post-implementation review. Ticketing systems, which IT support teams use to track and manage requests and incidents, are also addressed, including the information that should be captured in a support ticket, how tickets are escalated between support tiers, and how ticket documentation contributes to the organization's knowledge base over time. These operational competencies are as important to professional effectiveness as technical skills and deserve serious attention during exam preparation.
Safety and Environmental Procedures
Physical safety and environmental responsibility are topics that the 220-1102 examination addresses in the context of the operational procedures domain. IT support professionals work with equipment that poses electrical hazards, contains toxic materials, and generates significant quantities of electronic waste, and the examination tests knowledge of the practices and regulations that govern safe and responsible handling of this equipment. Electrostatic discharge, commonly abbreviated as ESD, is a risk that can damage sensitive electronic components invisibly, and candidates must understand how to use antistatic wrist straps, antistatic mats, and antistatic bags to protect components during handling and transport.
Proper disposal of IT equipment and consumables is a regulatory and environmental responsibility that the examination addresses through questions about e-waste disposal regulations, the handling of batteries including lithium-ion and lead-acid types found in laptops and uninterruptible power supplies, and the disposal of toner cartridges and display devices that contain hazardous materials. Material safety data sheets, now more commonly called safety data sheets, provide information about the hazardous properties of chemical substances and the precautions required when working with them, and candidates should understand what these documents are and when they are relevant to IT support work. These topics may seem peripheral compared to technical configuration knowledge but they appear consistently on the examination and carry real-world importance for workplace safety and regulatory compliance.
Software Troubleshooting Approach
Software troubleshooting accounts for approximately twenty-two percent of the 220-1102 examination and covers the systematic approaches and specific techniques that IT support professionals use to diagnose and resolve software problems on Windows systems. The examination emphasizes a structured troubleshooting methodology that begins with identifying the problem by gathering information from the user and the affected system, establishing a theory of probable cause based on the symptoms observed, testing the theory to confirm or revise it, establishing a plan of action, implementing the solution, verifying full system functionality, and documenting the findings and resolution for future reference.
Common Windows software issues tested on the examination include system slowness caused by resource exhaustion or malware, application crashes and error messages, boot failures at various stages of the startup process, update failures, and profile corruption that prevents users from logging in successfully. For each category of problem, the examination expects candidates to know which diagnostic tools are appropriate, what information those tools provide, and how to interpret that information to identify the root cause of the problem. Safe mode, the Windows Recovery Environment, System Restore, and the various repair options available during Windows startup are tools that the examination tests in the context of recovering systems that have become unstable or unbootable due to software problems.
Browser and Application Issues
Web browsers are among the most frequently used applications in any business environment, and browser-related issues represent a common category of support requests that IT professionals handle. The 220-1102 examination covers browser configuration and troubleshooting topics including clearing cache and cookies to resolve loading issues, managing browser extensions that can cause performance problems or security risks, configuring proxy settings for environments that route web traffic through a proxy server, and understanding how browser security settings affect the ability to access certain websites and web applications.
Application installation, compatibility, and removal are practical topics that the examination addresses in the context of common support scenarios. Candidates must understand how Windows installs and tracks applications, how to use the Programs and Features control panel applet to manage installed software, and how to address situations where applications fail to install, run incorrectly, or cannot be properly uninstalled through standard methods. Compatibility mode settings that allow older applications to run on newer versions of Windows, application virtualization concepts that isolate applications from the underlying operating system, and the role of software licensing in determining how applications can be deployed and used in a business environment are all areas where the examination tests practical knowledge relevant to support work.
Remote Access Technologies
Remote access technologies allow IT support professionals to assist users without traveling to their physical location, which is an essential capability in organizations with distributed workforces or multiple office locations. The 220-1102 examination covers the major remote access tools and protocols that support professionals use, including Remote Desktop Protocol for accessing Windows systems remotely, virtual private network technologies that secure remote connections over public networks, and third-party remote support tools that provide additional capabilities beyond what the built-in Windows remote access features offer.
Candidates must understand the security considerations associated with remote access, including how to ensure that remote connections are encrypted, how to verify the identity of the system being connected to, and how to handle sensitive user data encountered during a remote support session. Remote access policies and the principle of obtaining explicit user consent before accessing a user's system remotely are professional and ethical considerations that the examination addresses within the operational procedures domain. The practical experience of using remote access tools is valuable preparation for examination questions that describe remote support scenarios and ask candidates to identify the appropriate tools or procedures for resolving the described issue.
Scripting and Automation Basics
The 220-1102 examination includes foundational content on scripting and automation that reflects the growing importance of these skills even at the entry level of IT support. Candidates are not expected to write complex scripts from scratch, but they must understand the basic concepts of scripting, the common scripting languages used in Windows and cross-platform environments, and the types of tasks that scripting can automate to improve efficiency and consistency in IT support operations. Windows PowerShell, batch files, Python, and Bash are scripting environments that the examination references at a conceptual level.
Use cases for scripting in IT support environments include automating repetitive tasks such as user account creation, log file cleanup, software deployment, and system configuration verification. Candidates must understand why automating these tasks through scripts is preferable to performing them manually when they must be performed consistently across many systems, and what risks must be managed when running scripts in a production environment. The examination does not require candidates to read or write complex script code but does expect them to recognize common scripting constructs and understand the general purpose and function of scripts encountered in a support context.
