Amazon AWS Certified Solutions Architect - Professional SAP-C02 Practice Test 67

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.

Question 661

A deployed environment still does not meet the original requirement: A private S3 origin behind CloudFront must block direct public object requests while allowing authorized distribution reads. Which root cause is most consistent with the observation?

  1. Raw CloudTrail logs were collected but no managed threat-detection findings were enabled
  2. Individual account stacks were created manually and drift from the approved baseline
  3. A public bucket policy exposes origin objects outside the intended CloudFront access path
  4. Traffic bypasses inspection endpoints, so rules exist but are never reached

Explanation

Correct Answer

C:

This is the technical design error aligned with the unmet requirement. CloudFront OAC signs origin requests and supports restrictive private S3 bucket policies. The appropriate correction is: Configure CloudFront Origin Access Control with an origin bucket policy restricted to the distribution. The control should then be tested by verifying that CloudFront retrieves approved objects while direct anonymous S3 URLs are rejected.

Incorrect Answers

A:

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

B:

Individual account stacks were created manually and drift from the approved baseline. The stated evidence instead indicates: A public bucket policy exposes origin objects outside the intended CloudFront access path.

D:

Traffic bypasses inspection endpoints, so rules exist but are never reached. The stated evidence instead indicates: A public bucket policy exposes origin objects outside the intended CloudFront access path.

Question 662

A deployed environment still does not meet the original requirement: A Lambda-backed API team wants to expose only ten percent of traffic to a new function revision before promoting it. What design flaw is the best match for the reported condition?

  1. The function's unqualified ARN always invokes latest code for all users, bypassing version routing
  2. A successful compilation is treated as proof that the release is safe and functional
  3. The disaster-recovery Region has no local image copy and the deployment assumes remote registry availability
  4. A single active Region was incorrectly advertised as having near-zero recovery time

Explanation

Correct Answer

A:

This is the technical design error aligned with the unmet requirement. Lambda aliases support weighted traffic between published versions with monitored promotion. The appropriate correction is: Publish a Lambda version and configure weighted alias routing with deployment alarms. The control should then be tested by verifying that The alias sends the intended approximate percentage to the canary version and reverts after a simulated alarm.

Incorrect Answers

B:

A successful compilation is treated as proof that the release is safe and functional. The stated evidence instead indicates: The function's unqualified ARN always invokes latest code for all users, bypassing version routing.

C:

The disaster-recovery Region has no local image copy and the deployment assumes remote registry availability. The stated evidence instead indicates: The function's unqualified ARN always invokes latest code for all users, bypassing version routing.

D:

A single active Region was incorrectly advertised as having near-zero recovery time. The stated evidence instead indicates: The function's unqualified ARN always invokes latest code for all users, bypassing version routing.

Question 663

An enterprise architecture team faces this design requirement: An internal monolithic API has independently scalable request handlers and low idle traffic. Which option best aligns with the business and technical requirement?

  1. Use AWS Transfer Family with a supported SFTP endpoint and appropriate identity and S3 permissions
  2. Evaluate AWS Storage Gateway file or volume gateway mode against existing file protocol and caching requirements
  3. Extract suitable endpoints to API Gateway and Lambda with explicit authentication, throttling and timeout controls
  4. Migrate shared application files to Amazon EFS with appropriate mount targets and throughput configuration

Explanation

Correct Answer

C:

Serverless APIs can separate scaling from continuously provisioned application servers. The required architecture outcome is: An internal monolithic API has independently scalable request handlers and low idle traffic. Validate this choice by checking that Isolated handlers scale according to request demand and meet p95 latency and authorization targets.

Incorrect Answers

A:

Partners are forced to replace SFTP clients with AWS SDK calls without business approval. The specific problem here is that always-on monolith capacity is required merely to handle infrequent independent endpoints.

B:

A direct S3 SDK rewrite was imposed on workloads that cannot change their file interface. The specific problem here is that always-on monolith capacity is required merely to handle infrequent independent endpoints.

D:

Local instance disks are wrongly used as a shared durable POSIX file system. The specific problem here is that always-on monolith capacity is required merely to handle infrequent independent endpoints.

Question 664

An architecture review recommends this solution: Enable S3 Cross-Region Replication with correct versioning, role permissions and ownership controls. The motivating situation is: Customer-uploaded S3 objects must appear in a second Region for durability and region-isolation objectives. Which statement explains why the recommendation solves the specific problem?

  1. Inbound Resolver endpoints enable hybrid clients to ask VPC-associated private-zone DNS questions
  2. Cross-Region Replication asynchronously copies eligible objects between configured buckets
  3. Cross-account backup isolation reduces the effect of compromise of an application account
  4. Aurora Global Database supports low-latency crossregional replication with explicit recovery operations

Explanation

Correct Answer

B:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Enable S3 Cross-Region Replication with correct versioning, role permissions and ownership controls. The expected supporting evidence is: Newly created and eligible changed objects arrive in the destination bucket with expected encryption.

Incorrect Answers

A:

On-premises DNS has no forwarding path into the VPC's Route 53 Resolver. The stated evidence instead indicates: Only source-region S3 versioning is enabled, but no replication rule or role exists.

C:

Every backup copy resides in the same administration boundary as the threatened workloads. The stated evidence instead indicates: Only source-region S3 versioning is enabled, but no replication rule or role exists.

D:

A single-Region Aurora cluster lacks a suitable crossregional disaster recovery target. The stated evidence instead indicates: Only source-region S3 versioning is enabled, but no replication rule or role exists.

Question 665

A professional architect is reviewing two independent workstreams. Requirement A: A Kinesis stream has adequate shard write capacity but multiple consumers compete for read throughput and fall behind. Requirement B: An SNS topic invokes an asynchronous HTTP subscriber with intermittent failures and business needs controlled redelivery. Choose TWO actions that directly address these separate problems.

  1. Configure the supported subscription delivery policy, retries and dead-letter queue where applicable
  2. Review capacity provider strategy, instance-type resources and task placement requirements
  3. Enable and test DynamoDB point-in-time recovery for the table and recovery runbook
  4. Use enhanced fan-out for supported registered consumers or otherwise allocate read capacity explicitly
  5. Pair an AWS Config detection rule with controlled Systems Manager Automation remediation and change safeguards

Explanation

Correct Answers

A:

This action meets the independently stated requirement B: An SNS topic invokes an asynchronous HTTP subscriber with intermittent failures and business needs controlled redelivery. SNS subscriber reliability relies on delivery retries and appropriately configured dead-letter destinations. A direct acceptance check is: Failed deliveries retry under the configured policy and exhausted messages reach the DLQ.

D:

This action meets the independently stated requirement A: A Kinesis stream has adequate shard write capacity but multiple consumers compete for read throughput and fall behind. Kinesis enhanced fan-out provides dedicated consumer read throughput within service limits. A direct acceptance check is: Each registered consumer receives an independent read-throughput path and lag falls during peak events.

Incorrect Answers

B:

This action targets a different technical need: An ECS cluster has enough total CPU but tasks stay pending due to unsuitable placement and capacity provider configuration. It does not replace either required solution in A or B. ECS placement depends on available per-host resources and declared capacity-provider strategy; verify the two stated requirements independently rather than accepting an unrelated change.

C:

This action targets a different technical need: A DynamoDB application requires recovery from accidental writes to an earlier point within a month. It does not replace either required solution in A or B. DynamoDB PITR restores to a selected point within its available recovery window; verify the two stated requirements independently rather than accepting an unrelated change.

E:

This action targets a different technical need: An S3 bucket is repeatedly made public and security wants prompt correction beyond simply generating findings. It does not replace either required solution in A or B. Config rules can invoke automations for selected remediable configuration noncompliance; verify the two stated requirements independently rather than accepting an unrelated change.

Question 666

For the enterprise requirement "A business must migrate production database tables while serving users until the final narrow cutover", the team implemented this change: Use staged schema compatibility, full-load plus CDC migration and controlled dual-environment cutover tests. What would most directly validate the implementation?

  1. The job executes at its configured schedule while no dedicated idle EC2 host is required
  2. Each proposed migration wave includes dependencies required for a functional smoke test
  3. A forced downstream failure follows tested compensation logic without duplicating completed orders
  4. Source and destination data reconcile, CDC lag reaches the target and switching endpoints remains reversible

Explanation

Correct Answer

D:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. Online database migration requires ongoing change capture and carefully managed cutover semantics. The acceptance condition is linked directly to the scenario: A business must migrate production database tables while serving users until the final narrow cutover.

Incorrect Answers

A:

The job executes at its configured schedule while no dedicated idle EC2 host is required. However, this does not establish the required outcome: source and destination data reconcile, CDC lag reaches the target and switching endpoints remains reversible.

B:

Each proposed migration wave includes dependencies required for a functional smoke test. However, this does not establish the required outcome: source and destination data reconcile, CDC lag reaches the target and switching endpoints remains reversible.

C:

A forced downstream failure follows tested compensation logic without duplicating completed orders. However, this does not establish the required outcome: source and destination data reconcile, CDC lag reaches the target and switching endpoints remains reversible.

Question 667

An architecture review recommends this solution: Configure EventBridge archives and event replay with selection patterns and measured retention. The motivating situation is: A busy event-routing platform must retain dropped partner events for later controlled replay after a bug fix. Which technical principle most strongly justifies this recommendation?

  1. SQS dead-letter queues preserve failed messages for separate inspection and remediation
  2. RDS Multi-AZ provides standby capacity for automated intra-Region failover, not read scaling by itself
  3. Compute Savings Plans discount eligible compute spending with an hourly commitment
  4. EventBridge event archives retain matching historical events for later replay

Explanation

Correct Answer

D:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Configure EventBridge archives and event replay with selection patterns and measured retention. The expected supporting evidence is: Events captured during the fault can be replayed to a corrected consumer after recovery.

Incorrect Answers

A:

Repeated retries of one failed message prevent useful error isolation and redrive workflow. The stated evidence instead indicates: No event archive exists to replay notifications that failed during downstream processing.

B:

Single-AZ database storage and compute are a single zonal failure domain. The stated evidence instead indicates: No event archive exists to replay notifications that failed during downstream processing.

C:

Stable compute baseline is paid at on-demand rates without analyzed commitments. The stated evidence instead indicates: No event archive exists to replay notifications that failed during downstream processing.

Question 668

An architecture review recommends this solution: Set up AWS Cost Anomaly Detection with relevant monitors and alert subscriptions. The motivating situation is: Variable monthly expenses must trigger alerts for unusual spending spikes without predefined per-service thresholds. Which technical principle most strongly justifies this recommendation?

  1. Compute Optimizer uses resource metrics and recommendations but must be checked against workload SLOs
  2. Cost Anomaly Detection learns spending patterns and flags unusual expenditures
  3. Cost allocation tags must be activated before they appear in billing cost analytics
  4. Service-specific delegated administration provides controlled cross-account security operations

Explanation

Correct Answer

B:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Set up AWS Cost Anomaly Detection with relevant monitors and alert subscriptions. The expected supporting evidence is: A synthetic or observed unusual cost pattern appears in anomaly alerts with impacted spend drivers.

Incorrect Answers

A:

Instances were resized from average CPU alone despite memory or traffic constraints. The stated evidence instead indicates: Static budgets cannot explain or detect each atypical spend pattern promptly.

C:

Resource tags were never activated as billing cost allocation dimensions. The stated evidence instead indicates: Static budgets cannot explain or detect each atypical spend pattern promptly.

D:

Management-account-only operations were mistaken for necessary daily centralized security administration. The stated evidence instead indicates: Static budgets cannot explain or detect each atypical spend pattern promptly.

Question 669

For the enterprise requirement "A multinational website repeatedly serves cacheable large assets and incurs high origin data-transfer and request charges", the team implemented this change: Tune CloudFront cache policies and origin behavior to increase cache hits while honoring freshness limits. What would most directly validate the implementation?

  1. Actual eligible usage receives commitment coverage while variable spikes remain flexible
  2. The repeated key lookup hits DAX with lower latency while noncacheable paths use the underlying table
  3. Origin request count and cacheable transferred bytes fall without serving stale protected content
  4. Free storage stays above emergency thresholds while capacity grows within policy rather than being oversized initially

Explanation

Correct Answer

C:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. Effective caching can reduce origin load and transfer cost for eligible content. The acceptance condition is linked directly to the scenario: A multinational website repeatedly serves cacheable large assets and incurs high origin data-transfer and request charges.

Incorrect Answers

A:

Actual eligible usage receives commitment coverage while variable spikes remain flexible. However, this does not establish the required outcome: origin request count and cacheable transferred bytes fall without serving stale protected content.

B:

The repeated key lookup hits DAX with lower latency while noncacheable paths use the underlying table. However, this does not establish the required outcome: origin request count and cacheable transferred bytes fall without serving stale protected content.

D:

Free storage stays above emergency thresholds while capacity grows within policy rather than being oversized initially. However, this does not establish the required outcome: origin request count and cacheable transferred bytes fall without serving stale protected content.

Question 670

An architecture review recommends this solution: Configure S3 replication rules with correct versioning and KMS permissions for destination encrypted objects. The motivating situation is: Two Regions must retain independently encrypted object replicas to meet recovery requirements during a source Region failure. Which principle would a reviewer use to defend this design?

  1. Pilot light retains critical replicated services while reconstructing additional capacity during recovery
  2. S3 encrypted object replication needs versioning and appropriate replication-role KMS authorization
  3. Active-active architectures provide immediate regional capacity but require safe multi-Region data behavior
  4. DAX offers managed in-memory caching for eligible DynamoDB read workloads

Explanation

Correct Answer

B:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Configure S3 replication rules with correct versioning and KMS permissions for destination encrypted objects. The expected supporting evidence is: Eligible new source objects replicate with appropriate destination encryption and remain readable during source outage.

Incorrect Answers

A:

Every component must be rebuilt from scratch after failure, despite a tighter RTO. The stated evidence instead indicates: The destination bucket is present but replication cannot use the destination KMS key.

C:

A single active Region was incorrectly advertised as having near-zero recovery time. The stated evidence instead indicates: The destination bucket is present but replication cannot use the destination KMS key.

D:

Every read request traverses the backing DynamoDB service despite highly reusable cacheable data. The stated evidence instead indicates: The destination bucket is present but replication cannot use the destination KMS key.
