Amazon AWS Certified Solutions Architect - Professional SAP-C02 Practice Test 34

Question 330

An architecture review recommends this solution: Capture resources in versioned CloudFormation or CDK definitions and deploy through reviewed pipelines. The motivating situation is: Cloud infrastructure is built manually for each test environment and nobody knows which resources can be reproduced. Why does this approach fit the stated design constraints?

  1. Infrastructure as code supports repeatability, reviews and automated lifecycle controls
  2. Incremental strangler migration reduces cutover risk through bounded feature replacement
  3. CDC-based event distribution can modernize delayed batch data propagation
  4. Fargate can run supported ECS container tasks without customer-managed worker hosts

Explanation

Correct Answer

A:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Capture resources in versioned CloudFormation or CDK definitions and deploy through reviewed pipelines. The expected supporting evidence is: A fresh environment can be recreated from code with predictable parameters and drift checks.

Incorrect Answers

B:

An all-at-once replacement has unacceptable outage and rollback risk. The stated evidence instead indicates: Console changes have no reproducible declarative infrastructure state.

C:

All consumers wait for a nightly export despite a near-real-time freshness requirement. The stated evidence instead indicates: Console changes have no reproducible declarative infrastructure state.

D:

Dedicated EC2 servers remain the scaling bottleneck for stateless containerized workloads. The stated evidence instead indicates: Console changes have no reproducible declarative infrastructure state.

Question 331

A deployed environment still does not meet the original requirement: A customer-facing Lambda API has unacceptable first-request latency after inactive periods despite low average invocation cost. What design flaw is the best match for the reported condition?

  1. Misses from different edge caches repeatedly burden the same origin
  2. Shared per-shard read throughput is divided among too many polling consumers
  3. On-demand initialization latency is not addressed for the critical invocation path
  4. Teams purchase more RIs independently without measuring existing shared coverage

Explanation

Correct Answer

C:

This is the technical design error aligned with the unmet requirement. Lambda provisioned concurrency keeps selected execution environments initialized to reduce startup latency. The appropriate correction is: Configure provisioned concurrency for selected published function aliases with suitable demand planning. The control should then be tested by verifying that Cold-start spikes fall for provisioned requests and concurrency utilization stays within budget.

Incorrect Answers

A:

Misses from different edge caches repeatedly burden the same origin. The stated evidence instead indicates: On-demand initialization latency is not addressed for the critical invocation path.

B:

Shared per-shard read throughput is divided among too many polling consumers. The stated evidence instead indicates: On-demand initialization latency is not addressed for the critical invocation path.

D:

Teams purchase more RIs independently without measuring existing shared coverage. The stated evidence instead indicates: On-demand initialization latency is not addressed for the critical invocation path.

Question 332

A deployed environment still does not meet the original requirement: Many workload VPCs need access to a privately published service without opening routing to the provider's whole VPC. What explains why the stated requirement was not met?

  1. Overlapping network prefixes make ordinary VPC peering route selection ambiguous
  2. A single Direct Connect circuit creates a site-to-cloud connectivity single point of failure
  3. A broad VPC peering link was used where a service-scoped private access path was needed
  4. Static budgets cannot explain or detect each atypical spend pattern promptly

Explanation

Correct Answer

C:

This is the technical design error aligned with the unmet requirement. AWS PrivateLink exposes a selected service to consumers without full network-to-network reachability. The appropriate correction is: Expose the provider through an endpoint service behind a Network Load Balancer and create consumer interface VPC endpoints. The control should then be tested by verifying that Consumer instances reach only the approved PrivateLink service while unrelated provider subnets remain unreachable.

Incorrect Answers

A:

Overlapping network prefixes make ordinary VPC peering route selection ambiguous. The stated evidence instead indicates: A broad VPC peering link was used where a service-scoped private access path was needed.

B:

A single Direct Connect circuit creates a site-to-cloud connectivity single point of failure. The stated evidence instead indicates: A broad VPC peering link was used where a service-scoped private access path was needed.

D:

Static budgets cannot explain or detect each atypical spend pattern promptly. The stated evidence instead indicates: A broad VPC peering link was used where a service-scoped private access path was needed.

Question 333

A professional architect is reviewing two independent workstreams. Requirement A: Six VPCs in three accounts need private east-west connectivity without an O(N²) peering mesh. Requirement B: A multi-account organization must prevent member accounts from disabling mandatory CloudTrail trails even when local administrators hold broad IAM policies. Select TWO actions, one for each independently scoped requirement.

  1. Apply a targeted Organizations service control policy denying prohibited CloudTrail disablement actions in affected OUs
  2. Configure Security Hub delegated administrator and member account aggregation or finding aggregation as supported
  3. Attach the VPCs to one centrally governed Transit Gateway and propagate approved attachment routes
  4. Expose the provider through an endpoint service behind a Network Load Balancer and create consumer interface VPC endpoints
  5. Distribute worker nodes and eligible pods across multiple AZs with topology rules and disruption-aware service routing

Explanation

Correct Answers

A:

This action meets the independently stated requirement B: A multi-account organization must prevent member accounts from disabling mandatory CloudTrail trails even when local administrators hold broad IAM policies. Service control policies set permission ceilings for member account principals and cannot grant access themselves. A direct acceptance check is: An administrator's disable request is denied while an authorized central management path remains available.

C:

This action meets the independently stated requirement A: Six VPCs in three accounts need private east-west connectivity without an O(N²) peering mesh. Transit Gateway supplies centralized transitive VPC connectivity when attachment route tables and security policies are configured. A direct acceptance check is: Approved application subnets reach each other through Transit Gateway routes and unauthorized segments remain isolated.

Incorrect Answers

B:

This action targets a different technical need: Security analysts need one cross-account aggregation view of prioritized findings without requesting console access in every workload account. It does not replace either required solution in A or B. Security Hub delegated administration centralizes findings while each source account retains its own resources; verify the two stated requirements independently rather than accepting an unrelated change.

D:

This action targets a different technical need: Many workload VPCs need access to a privately published service without opening routing to the provider's whole VPC. It does not replace either required solution in A or B. AWS PrivateLink exposes a selected service to consumers without full network-to-network reachability; verify the two stated requirements independently rather than accepting an unrelated change.

E:

This action targets a different technical need: A latency-sensitive API running in EKS cannot tolerate a single Availability Zone outage. It does not replace either required solution in A or B. Multi-AZ Kubernetes workloads need scheduled replicas and correctly configured networking across zones; verify the two stated requirements independently rather than accepting an unrelated change.

Question 334

A professional architect is reviewing two independent workstreams. Requirement A: An estate of supported Linux and Windows VMs must rehost to EC2 with minimal application modification and short cutovers. Requirement B: A monolithic Windows process has been decomposed into HTTP services that can run in managed containers without operating its own servers. Which TWO recommendations jointly satisfy requirements A and B?

  1. Package services into supported containers and deploy with ECS on Fargate and scalable load balancing
  2. Use AWS Application Migration Service for compatible server replication, test launches and cutover orchestration
  3. Introduce caching with explicit expiry and invalidation policies using CloudFront or ElastiCache as appropriate
  4. Deploy a supported EKS architecture with managed control plane and appropriate node or Fargate capacity
  5. Use AWS DataSync agents and tasks with scheduling and integrity validation

Explanation

Correct Answers

A:

This action meets the independently stated requirement B: A monolithic Windows process has been decomposed into HTTP services that can run in managed containers without operating its own servers. Fargate can run supported ECS container tasks without customer-managed worker hosts. A direct acceptance check is: Services scale independently and teams do not manage EC2 container worker hosts.

B:

This action meets the independently stated requirement A: An estate of supported Linux and Windows VMs must rehost to EC2 with minimal application modification and short cutovers. AWS MGN supports continuous server replication and orchestrated rehosting validation. A direct acceptance check is: Replicated servers boot in AWS test VPCs with verified application functionality before cutover.

Incorrect Answers

C:

This action targets a different technical need: An ecommerce backend repeatedly recomputes expensive reads for product listings that change infrequently. It does not replace either required solution in A or B. Correct cache placement and invalidation reduce repeated work without violating freshness needs; verify the two stated requirements independently rather than accepting an unrelated change.

D:

This action targets a different technical need: A platform team requires Kubernetes APIs, admission policies and custom controllers while moving a container platform to AWS. It does not replace either required solution in A or B. EKS provides a managed Kubernetes control plane for teams using Kubernetes-native tooling; verify the two stated requirements independently rather than accepting an unrelated change.

E:

This action targets a different technical need: A company must perform recurring secure file synchronization from on-premises NAS into Amazon S3 with minimal custom scripting. It does not replace either required solution in A or B. AWS DataSync automates supported file and object movement with verification features; verify the two stated requirements independently rather than accepting an unrelated change.

Question 335

A deployed environment still does not meet the original requirement: A central security team needs automated detections for unusual cross-account API activity and suspected credential misuse. Which underlying cause should be investigated first?

  1. Console-created infrastructure diverged from versioned architecture definitions
  2. Raw CloudTrail logs were collected but no managed threat-detection findings were enabled
  3. Static IAM user access keys were embedded in the external CI configuration
  4. A public bucket policy exposes origin objects outside the intended CloudFront access path

Explanation

Correct Answer

B:

This is the technical design error aligned with the unmet requirement. GuardDuty consumes AWS data sources to identify suspicious behavior and report findings. The appropriate correction is: Enable GuardDuty organization-wide with designated administrator and configured regional coverage. The control should then be tested by verifying that A seeded supported suspicious event generates a finding and the delegated administrator can triage it.

Incorrect Answers

A:

Console-created infrastructure diverged from versioned architecture definitions. The stated evidence instead indicates: Raw CloudTrail logs were collected but no managed threat-detection findings were enabled.

C:

Static IAM user access keys were embedded in the external CI configuration. The stated evidence instead indicates: Raw CloudTrail logs were collected but no managed threat-detection findings were enabled.

D:

A public bucket policy exposes origin objects outside the intended CloudFront access path. The stated evidence instead indicates: Raw CloudTrail logs were collected but no managed threat-detection findings were enabled.

Question 336

An architecture review recommends this solution: Replace suitable stages with Step Functions orchestration and explicit retry, compensation and visibility states. The motivating situation is: A legacy orchestration service uses long polling and manual rollback scripts for multistep fulfillment. Which consideration makes this solution preferable to the original approach?

  1. Unified trace context and structured observability improve distributed troubleshooting
  2. EFS provides managed shared NFS file storage for distributed Linux clients
  3. Managed workflow orchestration makes retries, errors and compensation explicit
  4. Managed scheduling can invoke short-lived compute without operating a permanent cron host

Explanation

Correct Answer

C:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Replace suitable stages with Step Functions orchestration and explicit retry, compensation and visibility states. The expected supporting evidence is: A forced downstream failure follows tested compensation logic without duplicating completed orders.

Incorrect Answers

A:

Separate component logs cannot be correlated to customer transactions. The stated evidence instead indicates: Workflow state and failure recovery are hidden in fragile custom imperative scripts.

B:

Local instance disks are wrongly used as a shared durable POSIX file system. The stated evidence instead indicates: Workflow state and failure recovery are hidden in fragile custom imperative scripts.

D:

The only purpose of a 24/7 server is occasional timer-based work. The stated evidence instead indicates: Workflow state and failure recovery are hidden in fragile custom imperative scripts.

Question 337

For the enterprise requirement "Variable monthly expenses must trigger alerts for unusual spending spikes without predefined per-service thresholds", the team implemented this change: Set up AWS Cost Anomaly Detection with relevant monitors and alert subscriptions. Which outcome is the most meaningful acceptance test?

  1. Shared applicable discounts and uncovered on-demand baseline are visible by linked account
  2. Events from a test member account reach the central incident workflow and unauthorized senders are rejected
  3. Tested resized instances meet p95 latency goals while recommended savings are observed
  4. A synthetic or observed unusual cost pattern appears in anomaly alerts with impacted spend drivers

Explanation

Correct Answer

D:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. Cost Anomaly Detection learns spending patterns and flags unusual expenditures. The acceptance condition is linked directly to the scenario: Variable monthly expenses must trigger alerts for unusual spending spikes without predefined per-service thresholds.

Incorrect Answers

A:

Shared applicable discounts and uncovered on-demand baseline are visible by linked account. However, this does not establish the required outcome: a synthetic or observed unusual cost pattern appears in anomaly alerts with impacted spend drivers.

B:

Events from a test member account reach the central incident workflow and unauthorized senders are rejected. However, this does not establish the required outcome: a synthetic or observed unusual cost pattern appears in anomaly alerts with impacted spend drivers.

C:

Tested resized instances meet p95 latency goals while recommended savings are observed. However, this does not establish the required outcome: a synthetic or observed unusual cost pattern appears in anomaly alerts with impacted spend drivers.

Question 338

An architecture review recommends this solution: Benchmark supported arm64 builds on Graviton instance families and deploy only after compatibility validation. The motivating situation is: A mature EC2 service wants to reduce response latency and CPU cost by moving to Graviton while preserving custom native dependencies. Which architectural reasoning is most accurate for the choice?

  1. Graviton migration requires compatible architecture builds and representative workload benchmarking
  2. Kinesis stream performance depends on provisioned or on-demand capacity and balanced partition keys
  3. CloudFront edge caching reduces origin fetches for cacheable content
  4. Pilot light retains critical replicated services while reconstructing additional capacity during recovery

Explanation

Correct Answer

A:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Benchmark supported arm64 builds on Graviton instance families and deploy only after compatibility validation. The expected supporting evidence is: p95 latency and unit costs improve in a representative arm64 canary with all native libraries working.

Incorrect Answers

B:

Stream shard limits or skewed partition keys cannot handle incoming record throughput. The stated evidence instead indicates: The team assumes an x86 machine image and native binaries can run unchanged on arm64.

C:

Every static asset fetch goes to a distant origin instead of the edge cache. The stated evidence instead indicates: The team assumes an x86 machine image and native binaries can run unchanged on arm64.

D:

Every component must be rebuilt from scratch after failure, despite a tighter RTO. The stated evidence instead indicates: The team assumes an x86 machine image and native binaries can run unchanged on arm64.

Question 339

An architecture review recommends this solution: Validate platform, hypervisor and kernel compatibility before committing to a target deployment. The motivating situation is: A proprietary virtual appliance cannot run on AWS-supported instance drivers without vendor modifications. Why is this architecture appropriate for the described workload?

  1. A centralized migration tracking layer supports coordination across application teams
  2. Migration transfer methods must fit volume, available bandwidth and allowed downtime
  3. Platform migration viability depends on software support and hardware or driver compatibility
  4. Domain-aligned service boundaries require APIs and deliberate data ownership separation

Explanation

Correct Answer

C:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Validate platform, hypervisor and kernel compatibility before committing to a target deployment. The expected supporting evidence is: Vendor-certified testing proves that the appliance runs on the selected target or requires retain/replace decision.

Incorrect Answers

A:

Migration tasks are tracked in separate team documents with no common portfolio state. The stated evidence instead indicates: Source virtualization format was mistaken for a guarantee of target runtime compatibility.

B:

A simple online copy was selected without calculating network capacity and transfer duration. The stated evidence instead indicates: Source virtualization format was mistaken for a guarantee of target runtime compatibility.

D:

Shared data and internal method calls prevent independent deployment and scale. The stated evidence instead indicates: Source virtualization format was mistaken for a guarantee of target runtime compatibility.

Question 340

For the enterprise requirement "An enterprise wants line-item chargeback for data transfer and service usage across hundreds of accounts", the team implemented this change: Export AWS Cost and Usage Reports to S3 and query them with Athena or a billing data analysis workflow. Which evidence confirms the intended behavior under test?

  1. Revoking a staff member's assignment removes their delegated access without per-account user deletion
  2. Tested resized instances meet p95 latency goals while recommended savings are observed
  3. Finance can reconcile detailed usage line items to accounts and cost categories
  4. Eligible compute charges reflect the planned commitment discount and remaining coverage is visible

Explanation

Correct Answer

C:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. The Cost and Usage Report provides detailed billing facts for accountable cost analysis. The acceptance condition is linked directly to the scenario: An enterprise wants line-item chargeback for data transfer and service usage across hundreds of accounts.

Incorrect Answers

A:

Revoking a staff member's assignment removes their delegated access without per-account user deletion. However, this does not establish the required outcome: finance can reconcile detailed usage line items to accounts and cost categories.

B:

Tested resized instances meet p95 latency goals while recommended savings are observed. However, this does not establish the required outcome: finance can reconcile detailed usage line items to accounts and cost categories.

D:

Eligible compute charges reflect the planned commitment discount and remaining coverage is visible. However, this does not establish the required outcome: finance can reconcile detailed usage line items to accounts and cost categories.
