Amazon AWS Certified Solutions Architect - Professional SAP-C02 Practice Test 66

Question 650

A professional architect is reviewing two independent workstreams. Requirement A: Hundreds of virtual machines require orchestrated recovery into AWS after a primary on-premises site failure. Requirement B: Network administrators must manage a shared subnet centrally while application accounts place their own resources in it. Select TWO actions, one for each independently scoped requirement.

  1. Use AWS Backup cross-account copies into a protected backup account with isolated restore permissions
  2. Deploy an AWS Control Tower landing zone and Account Factory-based governance with planned organizational units
  3. Enable VPC subnet sharing through AWS RAM for eligible accounts in the same organization
  4. Use AWS Elastic Disaster Recovery with supported source replication and recovery drills
  5. Introduce a centrally managed translation or proxy layer with nonoverlapping service endpoints rather than directly peering overlapping networks

Explanation

Correct Answers

C:

This action meets the independently stated requirement B: Network administrators must manage a shared subnet centrally while application accounts place their own resources in it. VPC sharing separates network ownership from application resource ownership. A direct acceptance check is: Participant-owned permitted resources deploy into the shared subnet while networking account retains network ownership.

D:

This action meets the independently stated requirement A: Hundreds of virtual machines require orchestrated recovery into AWS after a primary on-premises site failure. AWS Elastic Disaster Recovery supports block-level replication and automated recovery launches. A direct acceptance check is: A drilled failover boots recoverable instances and meets tested recovery objectives and dependency order.

Incorrect Answers

A:

This action targets a different technical need: Financial backups must survive destruction of the primary application account by a compromised administrator. It does not replace either required solution in A or B. Cross-account backup isolation reduces the effect of compromise of an application account; verify the two stated requirements independently rather than accepting an unrelated change.

B:

This action targets a different technical need: A startup expects to grow from five accounts to 100 and needs baseline account vending and preventive guardrails. It does not replace either required solution in A or B. AWS Control Tower provides managed landing-zone governance and standardized account provisioning; verify the two stated requirements independently rather than accepting an unrelated change.

E:

This action targets a different technical need: Two acquired subsidiaries have overlapping RFC1918 VPC CIDRs but must exchange traffic with a shared integration endpoint. It does not replace either required solution in A or B. Overlapping address spaces require translation or service-level isolation rather than simple routed peering; verify the two stated requirements independently rather than accepting an unrelated change.

Question 651

An architecture review recommends this solution: Enable VPC subnet sharing through AWS RAM for eligible accounts in the same organization. The motivating situation is: Network administrators must manage a shared subnet centrally while application accounts place their own resources in it. Which principle would a reviewer use to defend this design?

  1. AWS Config aggregators consolidate configuration and compliance data without changing source resources
  2. AWS Control Tower provides managed landing-zone governance and standardized account provisioning
  3. VPC sharing separates network ownership from application resource ownership
  4. Consolidated billing can share eligible reservations across member accounts subject to sharing settings

Explanation

Correct Answer

C:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Enable VPC subnet sharing through AWS RAM for eligible accounts in the same organization. The expected supporting evidence is: Participant-owned permitted resources deploy into the shared subnet while networking account retains network ownership.

Incorrect Answers

A:

Local Config assessments exist but no aggregation exposes cross-account status. The stated evidence instead indicates: Separate VPC copies and peering links were created instead of sharing centrally governed subnets.

B:

New accounts are assembled by ad hoc scripts with inconsistent security baselines. The stated evidence instead indicates: Separate VPC copies and peering links were created instead of sharing centrally governed subnets.

D:

RI purchases are evaluated only in the purchasing account without considering shared billing treatment. The stated evidence instead indicates: Separate VPC copies and peering links were created instead of sharing centrally governed subnets.

Question 652

A professional architect is reviewing two independent workstreams. Requirement A: Branch offices retain file shares locally but need backup and tiered cloud-backed storage without replacing every client. Requirement B: Operations cannot trace a customer transaction once it crosses more than six loosely coupled services. Which TWO recommendations jointly satisfy requirements A and B?

  1. Evaluate AWS Storage Gateway file or volume gateway mode against existing file protocol and caching requirements
  2. Introduce consistent tracing and structured correlation with CloudWatch and an OpenTelemetry-compatible collector where appropriate
  3. Perform application dependency discovery and group connected workloads into migration waves
  4. Evaluate Amazon MQ with an appropriate compatible engine and migrate broker connections in stages
  5. Apply the strangler pattern, routing one well-defined capability at a time to a tested new service

Explanation

Correct Answers

A:

This action meets the independently stated requirement A: Branch offices retain file shares locally but need backup and tiered cloud-backed storage without replacing every client. Storage Gateway helps bridge supported on-premises storage protocols to AWS-backed storage. A direct acceptance check is: Local clients retain supported file access while selected data is persisted to eligible AWS storage.

B:

This action meets the independently stated requirement B: Operations cannot trace a customer transaction once it crosses more than six loosely coupled services. Unified trace context and structured observability improve distributed troubleshooting. A direct acceptance check is: An end-to-end test request shows linked spans and reveals downstream latency without leaking credentials.

Incorrect Answers

C:

This action targets a different technical need: A corporation has hundreds of interdependent on-premises services and cannot establish which databases must move together. It does not replace either required solution in A or B. Dependency mapping reduces migration risk by revealing the actual application interaction graph; verify the two stated requirements independently rather than accepting an unrelated change.

D:

This action targets a different technical need: A message-processing application still uses an on-premises ActiveMQ-compatible broker and cannot immediately rewrite producers. It does not replace either required solution in A or B. Amazon MQ can support compatible managed message brokers when protocol continuity matters; verify the two stated requirements independently rather than accepting an unrelated change.

E:

This action targets a different technical need: A legacy monolith must be separated into business capabilities gradually without taking a risky one-time rewrite. It does not replace either required solution in A or B. Incremental strangler migration reduces cutover risk through bounded feature replacement; verify the two stated requirements independently rather than accepting an unrelated change.

Question 653

A professional architect is reviewing two independent workstreams. Requirement A: A message-processing application still uses an on-premises ActiveMQ-compatible broker and cannot immediately rewrite producers. Requirement B: A large retail monolith has tightly coupled inventory, checkout and customer modules that scale as one deployment. Which TWO responses resolve the stated issues without substituting unrelated mechanisms?

  1. Identify bounded contexts and isolate independently deployable modules with explicit APIs and data ownership
  2. Assess license portability, dedicated-host requirements and AWS License Manager before choosing targets
  3. Evaluate Amazon MQ with an appropriate compatible engine and migrate broker connections in stages
  4. Introduce change data capture and an event stream or bus with replay and idempotent consumers
  5. Build a governed S3-centered data lake with AWS Glue metadata and appropriate analytics services

Explanation

Correct Answers

A:

This action meets the independently stated requirement B: A large retail monolith has tightly coupled inventory, checkout and customer modules that scale as one deployment. Domain-aligned service boundaries require APIs and deliberate data ownership separation. A direct acceptance check is: Inventory changes can deploy without forcing unrelated checkout and customer workflows through full regression.

C:

This action meets the independently stated requirement A: A message-processing application still uses an on-premises ActiveMQ-compatible broker and cannot immediately rewrite producers. Amazon MQ can support compatible managed message brokers when protocol continuity matters. A direct acceptance check is: Existing clients publish and consume messages with acceptable protocol compatibility after controlled cutover.

Incorrect Answers

B:

This action targets a different technical need: A Windows estate contains expensive licensed products whose licensing rights differ between shared tenancy and dedicated hosts. It does not replace either required solution in A or B. License entitlements must be assessed before migration architecture and instance selection; verify the two stated requirements independently rather than accepting an unrelated change.

D:

This action targets a different technical need: A legacy billing system runs nightly ETL and downstream consumers need near-real-time invoice changes. It does not replace either required solution in A or B. CDC-based event distribution can modernize delayed batch data propagation; verify the two stated requirements independently rather than accepting an unrelated change.

E:

This action targets a different technical need: A legacy reporting ETL cluster requires durable raw data sharing and easier scale-out queries across departments. It does not replace either required solution in A or B. A shared governed object-storage lake decouples data retention from individual processing engines; verify the two stated requirements independently rather than accepting an unrelated change.

Question 654

An enterprise architecture team faces this design requirement: A customer-facing Lambda API has unacceptable first-request latency after inactive periods despite low average invocation cost. Which proposed change addresses the stated constraint most directly?

  1. Configure provisioned concurrency for selected published function aliases with suitable demand planning
  2. Analyze transfer usage in CUR and network metrics; redesign unnecessary cross-AZ chatty application flows
  3. Add an appropriate CloudFront Origin Shield layer and adjust origin caching strategy
  4. Select an appropriate EBS gp3 volume with independently provisioned performance settings and test application throughput

Explanation

Correct Answer

A:

Lambda provisioned concurrency keeps selected execution environments initialized to reduce startup latency. The required architecture outcome is: A customer-facing Lambda API has unacceptable first-request latency after inactive periods despite low average invocation cost. Validate this choice by checking that Cold-start spikes fall for provisioned requests and concurrency utilization stays within budget.

Incorrect Answers

B:

Workload service calls repeatedly cross paid network boundaries without quantified need. The specific problem here is that on-demand initialization latency is not addressed for the critical invocation path.

C:

Misses from different edge caches repeatedly burden the same origin. The specific problem here is that on-demand initialization latency is not addressed for the critical invocation path.

D:

Gp2 capacity-linked performance assumptions lead to wasteful storage growth. The specific problem here is that on-demand initialization latency is not addressed for the critical invocation path.

Question 655

A deployed environment still does not meet the original requirement: An engineer repeatedly leaves management ports publicly accessible despite a configuration guardrail document. What explains why the stated requirement was not met?

  1. Metrics and logs are not organized into actionable per-service operational signals
  2. Static security policy documents are not technically enforced against resource drift
  3. Findings remain siloed in local account consoles and cannot be triaged centrally
  4. Role policies retain privileges indefinitely without evidence about actual service usage

Explanation

Correct Answer

B:

This is the technical design error aligned with the unmet requirement. AWS Config checks configuration changes against evaluable rules and supports managed remediation actions. The appropriate correction is: Add AWS Config evaluation for the risky security-group condition with controlled notification and remediation. The control should then be tested by verifying that A test ingress rule is flagged and corrected through the authorized remediation workflow.

Incorrect Answers

A:

Metrics and logs are not organized into actionable per-service operational signals. The stated evidence instead indicates: Static security policy documents are not technically enforced against resource drift.

C:

Findings remain siloed in local account consoles and cannot be triaged centrally. The stated evidence instead indicates: Static security policy documents are not technically enforced against resource drift.

D:

Role policies retain privileges indefinitely without evidence about actual service usage. The stated evidence instead indicates: Static security policy documents are not technically enforced against resource drift.

Question 656

An enterprise architecture team faces this design requirement: A read-heavy reporting application needs an up-to-date secondary regional database copy that can be promoted in a disaster. Which architecture decision best meets that precise requirement?

  1. Configure a suitable RDS cross-Region read replica where supported and rehearse replica promotion and endpoint changes
  2. Benchmark supported arm64 builds on Graviton instance families and deploy only after compatibility validation
  3. Configure Route 53 health checks with primary and secondary failover records and tested TTL behavior
  4. Configure protected AWS Backup Vault Lock compliance settings with appropriate retention and access governance

Explanation

Correct Answer

A:

Cross-Region read replicas are asynchronous and may require explicit promotion in recovery. The required architecture outcome is: A read-heavy reporting application needs an up-to-date secondary regional database copy that can be promoted in a disaster. Validate this choice by checking that Read replica lag is measured and promotion produces a usable independent writer during a DR drill.

Incorrect Answers

B:

The team assumes an x86 machine image and native binaries can run unchanged on arm64. The specific problem here is that a standard read replica is assumed to be a synchronous multi-Region failover mechanism without promotion.

C:

Records use ordinary simple routing without failover health awareness. The specific problem here is that a standard read replica is assumed to be a synchronous multi-Region failover mechanism without promotion.

D:

Backup administrators can freely delete critical recovery points despite required immutability. The specific problem here is that a standard read replica is assumed to be a synchronous multi-Region failover mechanism without promotion.

Question 657

An architecture review recommends this solution: Modernize to an appropriately configured Amazon Aurora cluster with multi-AZ storage and tested failover. The motivating situation is: A legacy database must meet high transactional availability and can accept conversion to an Aurora-compatible engine. What principle supports the selected implementation?

  1. EKS provides a managed Kubernetes control plane for teams using Kubernetes-native tooling
  2. Aurora offers managed high availability features for supported relational engines
  3. Regulatory and data-classification constraints affect target location and migration scope
  4. Event-driven boundaries isolate failure but require idempotency and message-delivery governance

Explanation

Correct Answer

B:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Modernize to an appropriately configured Amazon Aurora cluster with multi-AZ storage and tested failover. The expected supporting evidence is: A controlled writer failure maintains recoverable transactional access after cluster endpoint reconnection.

Incorrect Answers

A:

A non-Kubernetes orchestrator was chosen despite strict Kubernetes extension compatibility requirements. The stated evidence instead indicates: Application reliability still depends on one unmanaged database host and manual restores.

C:

Migration scheduling ignored data classification and jurisdictional control requirements. The stated evidence instead indicates: Application reliability still depends on one unmanaged database host and manual restores.

D:

Tight synchronous coupling propagates a noncritical downstream failure to the primary transaction. The stated evidence instead indicates: Application reliability still depends on one unmanaged database host and manual restores.

Question 658

An enterprise architecture team faces this design requirement: A corporation has hundreds of interdependent on-premises services and cannot establish which databases must move together. Which architecture decision best meets that precise requirement?

  1. Estimate transfer duration and select online versus physical transfer based on throughput, change rate and cutoff window
  2. Perform application dependency discovery and group connected workloads into migration waves
  3. Use staged schema compatibility, full-load plus CDC migration and controlled dual-environment cutover tests
  4. Assess license portability, dedicated-host requirements and AWS License Manager before choosing targets

Explanation

Correct Answer

B:

Dependency mapping reduces migration risk by revealing the actual application interaction graph. The required architecture outcome is: A corporation has hundreds of interdependent on-premises services and cannot establish which databases must move together. Validate this choice by checking that Each proposed migration wave includes dependencies required for a functional smoke test.

Incorrect Answers

A:

A simple online copy was selected without calculating network capacity and transfer duration. The specific problem here is that application lists omit runtime call dependencies and produce broken split-wave migrations.

C:

A one-time export leaves days of writes uncopied before final deployment. The specific problem here is that application lists omit runtime call dependencies and produce broken split-wave migrations.

D:

Licensing constraints were omitted until after destination EC2 instances were chosen. The specific problem here is that application lists omit runtime call dependencies and produce broken split-wave migrations.

Question 659

A professional architect is reviewing two independent workstreams. Requirement A: Governance wants one AWS Config compliance view from many accounts and Regions. Requirement B: Several accounts have steady EC2 and Fargate spend and need a commitment that applies to qualifying compute usage flexibly. Choose TWO actions that directly address these separate problems.

  1. Set up IAM Identity Center account assignments with role-scoped permission sets and centralized joiner-leaver management
  2. Analyze commitments then purchase an appropriate Compute Savings Plan based on supported usage coverage
  3. Analyze organization-wide RI utilization and coverage using consolidated billing reports
  4. Use AWS Elastic Disaster Recovery with supported source replication and recovery drills
  5. Configure a Config aggregator with organization or account sources and appropriate delegated read access

Explanation

Correct Answers

B:

This action meets the independently stated requirement B: Several accounts have steady EC2 and Fargate spend and need a commitment that applies to qualifying compute usage flexibly. Compute Savings Plans apply eligible usage discounts across supported services and configurations. A direct acceptance check is: Eligible compute charges reflect the planned commitment discount and remaining coverage is visible.

E:

This action meets the independently stated requirement A: Governance wants one AWS Config compliance view from many accounts and Regions. AWS Config aggregators consolidate configuration and compliance data without changing source resources. A direct acceptance check is: Central compliance dashboards include resource findings from configured participating accounts and Regions.

Incorrect Answers

A:

This action targets a different technical need: Business units need temporary developer access to multiple accounts but not permanent local IAM users. It does not replace either required solution in A or B. Central identity assignments reduce stale credentials and standardize workforce access; verify the two stated requirements independently rather than accepting an unrelated change.

C:

This action targets a different technical need: A company has shared Reserved Instances in its payer organization and wants to quantify benefit distribution across linked accounts. It does not replace either required solution in A or B. Consolidated billing can share eligible reservations across member accounts subject to sharing settings; verify the two stated requirements independently rather than accepting an unrelated change.

D:

This action targets a different technical need: Hundreds of virtual machines require orchestrated recovery into AWS after a primary on-premises site failure. It does not replace either required solution in A or B. AWS Elastic Disaster Recovery supports block-level replication and automated recovery launches; verify the two stated requirements independently rather than accepting an unrelated change.

Question 660

An enterprise architecture team faces this design requirement: A corporate SOC needs one prioritized security findings view across enabled security services and Regions. What is the most appropriate design for this workload?

  1. Enable AWS WAF logging to an appropriate destination with sensitive-data handling and analyze matched rules
  2. Enable Security Hub delegated administration and finding aggregation for the target accounts and Regions
  3. Use S3 Access Points or carefully scoped bucket policies to isolate each team's required object prefixes
  4. Use Systems Manager Patch Manager with patch baselines and maintenance-window runbooks

Explanation

Correct Answer

B:

Security Hub consolidates security posture and findings from participating services. The required architecture outcome is: A corporate SOC needs one prioritized security findings view across enabled security services and Regions. Validate this choice by checking that Security Hub centrally displays eligible standardized findings with source context preserved.

Incorrect Answers

A:

WAF rules are deployed without visibility into which requests they affect. The specific problem here is that findings remain siloed in local account consoles and cannot be triaged centrally.

C:

One overbroad bucket-level policy grants both teams access to all data. The specific problem here is that findings remain siloed in local account consoles and cannot be triaged centrally.

D:

Patch application is manual and lacks consistent baseline selection and change evidence. The specific problem here is that findings remain siloed in local account consoles and cannot be triaged centrally.
