Amazon AWS Certified Solutions Architect - Professional SAP-C02 Practice Test 70

Question 690

A deployed environment still does not meet the original requirement: A source MySQL workload must migrate to Amazon RDS MySQL without an engine conversion project. Which underlying cause should be investigated first?

  1. Source virtualization format was mistaken for a guarantee of target runtime compatibility
  2. Replicating table data alone does not translate incompatible source SQL constructs
  3. The migration plan assumes a new AWS Snowball Edge device can still be ordered even though new-customer ordering is unavailable
  4. Complex heterogeneous schema conversion was selected unnecessarily for a same-engine migration

Explanation

Correct Answer

D:

This is the technical design error aligned with the unmet requirement. Homogeneous migrations usually focus on data replication, compatibility details and cutover rather than engine-language rewrite. The appropriate correction is: Prefer a supported homogeneous DMS migration or native replication pattern with CDC where suitable. The control should then be tested by verifying that Destination table state stays synchronized and the application passes a reversible cutover test.

Incorrect Answers

A:

Source virtualization format was mistaken for a guarantee of target runtime compatibility. The stated evidence instead indicates: Complex heterogeneous schema conversion was selected unnecessarily for a same-engine migration.

B:

Replicating table data alone does not translate incompatible source SQL constructs. The stated evidence instead indicates: Complex heterogeneous schema conversion was selected unnecessarily for a same-engine migration.

C:

The migration plan assumes a new AWS Snowball Edge device can still be ordered even though new-customer ordering is unavailable. The stated evidence instead indicates: Complex heterogeneous schema conversion was selected unnecessarily for a same-engine migration.

Question 691

A professional architect is reviewing two independent workstreams. Requirement A: Operations needs one centralized queue of cost optimization recommendations from multiple AWS services. Requirement B: Two acquired subsidiaries have overlapping RFC1918 VPC CIDRs but must exchange traffic with a shared integration endpoint. Which TWO responses resolve the stated issues without substituting unrelated mechanisms?

  1. Enable S3 Cross-Region Replication with correct versioning, role permissions and ownership controls
  2. Use AWS Cost Optimization Hub with supported account enrollment and recommendation aggregation
  3. Establish a Transit Gateway peering attachment and add the appropriate static routes in both Transit Gateway route tables
  4. Introduce a centrally managed translation or proxy layer with nonoverlapping service endpoints rather than directly peering overlapping networks
  5. Export AWS Cost and Usage Reports to S3 and query them with Athena or a billing data analysis workflow

Explanation

Correct Answers

B:

This action meets the independently stated requirement A: Operations needs one centralized queue of cost optimization recommendations from multiple AWS services. Cost Optimization Hub consolidates and de-duplicates supported AWS cost recommendations. A direct acceptance check is: Finance sees prioritized savings opportunities and can distinguish overlapping cost recommendations.

D:

This action meets the independently stated requirement B: Two acquired subsidiaries have overlapping RFC1918 VPC CIDRs but must exchange traffic with a shared integration endpoint. Overlapping address spaces require translation or service-level isolation rather than simple routed peering. A direct acceptance check is: Traffic uses translated unique endpoint addresses and return packets reach the original client correctly.

Incorrect Answers

A:

This action targets a different technical need: Customer-uploaded S3 objects must appear in a second Region for durability and region-isolation objectives. It does not replace either required solution in A or B. Cross-Region Replication asynchronously copies eligible objects between configured buckets; verify the two stated requirements independently rather than accepting an unrelated change.

C:

This action targets a different technical need: Two regional Transit Gateways must exchange approved network prefixes without provisioning a separate VPC-to-VPC peering mesh. It does not replace either required solution in A or B. Transit Gateway peering requires explicit routing between the regional gateways; verify the two stated requirements independently rather than accepting an unrelated change.

E:

This action targets a different technical need: An enterprise wants line-item chargeback for data transfer and service usage across hundreds of accounts. It does not replace either required solution in A or B. The Cost and Usage Report provides detailed billing facts for accountable cost analysis; verify the two stated requirements independently rather than accepting an unrelated change.

Question 692

For the enterprise requirement "A multi-AZ production stack has never been tested with a failed Availability Zone during working hours", the team implemented this change: Run controlled AWS Fault Injection Service scenarios with safety guardrails and predeclared stop conditions. Which test result proves this architecture satisfies its stated constraint?

  1. The stack tolerates the injected zonal fault and stop alarms terminate experiments as planned
  2. Origin request count drops under a multi-edge cache miss test while freshness remains correct
  3. After a simulated endpoint failure, new DNS queries return the secondary healthy Region
  4. New instances become healthy before major traffic shift and rollback restores the previous code path

Explanation

Correct Answer

A:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. Fault injection validates real system behavior within approved experiment boundaries. The acceptance condition is linked directly to the scenario: A multi-AZ production stack has never been tested with a failed Availability Zone during working hours.

Incorrect Answers

B:

Origin request count drops under a multi-edge cache miss test while freshness remains correct. However, this does not establish the required outcome: the stack tolerates the injected zonal fault and stop alarms terminate experiments as planned.

C:

After a simulated endpoint failure, new DNS queries return the secondary healthy Region. However, this does not establish the required outcome: the stack tolerates the injected zonal fault and stop alarms terminate experiments as planned.

D:

New instances become healthy before major traffic shift and rollback restores the previous code path. However, this does not establish the required outcome: the stack tolerates the injected zonal fault and stop alarms terminate experiments as planned.

Question 693

A deployed environment still does not meet the original requirement: Unpredictably accessed objects are retained for a year, but no reliable access-frequency segmentation is known. Which root cause is most consistent with the observation?

  1. Instance-local caches cannot share consistent ephemeral state across horizontally scaled hosts
  2. Objects remain indefinitely in higher-cost storage despite a proven low-access retention pattern
  3. Stable compute baseline is paid at on-demand rates without analyzed commitments
  4. Fixed hot storage is retained for every object because teams cannot forecast access patterns

Explanation

Correct Answer

D:

This is the technical design error aligned with the unmet requirement. S3 Intelligent-Tiering can move eligible objects among access tiers based on access frequency. The appropriate correction is: Apply S3 Intelligent-Tiering with suitable monitoring and eligibility checks. The control should then be tested by verifying that Storage-class distribution follows observed access and availability constraints without extensive manual classification.

Incorrect Answers

A:

Instance-local caches cannot share consistent ephemeral state across horizontally scaled hosts. The stated evidence instead indicates: Fixed hot storage is retained for every object because teams cannot forecast access patterns.

B:

Objects remain indefinitely in higher-cost storage despite a proven low-access retention pattern. The stated evidence instead indicates: Fixed hot storage is retained for every object because teams cannot forecast access patterns.

C:

Stable compute baseline is paid at on-demand rates without analyzed commitments. The stated evidence instead indicates: Fixed hot storage is retained for every object because teams cannot forecast access patterns.

Question 694

An architecture review recommends this solution: Enable detailed Cost and Usage Reports with cost categories or properly activated allocation tags. The motivating situation is: A platform service incurs shared transfer charges that cannot be assigned to consuming product teams. Why does this approach fit the stated design constraints?

  1. EBS storage billing continues for allocated volumes until they are deleted or otherwise changed
  2. Systems Manager supports fleet patching with centralized baselines and maintenance windows
  3. S3 analytics and lifecycle rules target recoverable storage waste when retention is respected
  4. CUR data and explicit allocation logic improve auditable cost attribution

Explanation

Correct Answer

D:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Enable detailed Cost and Usage Reports with cost categories or properly activated allocation tags. The expected supporting evidence is: Chargeback results trace shared spend to accounted requests or accountable service consumers.

Incorrect Answers

A:

Unattached volumes are treated as free merely because they are not mounted. The stated evidence instead indicates: Shared costs are assigned by arbitrary percentage without service consumption evidence.

B:

Patch application is manual and lacks consistent baseline selection and change evidence. The stated evidence instead indicates: Shared costs are assigned by arbitrary percentage without service consumption evidence.

C:

Dormant storage versions and partial uploads accumulate without inventory or lifecycle governance. The stated evidence instead indicates: Shared costs are assigned by arbitrary percentage without service consumption evidence.

Question 695

For the enterprise requirement "An application runs a small cron job on a permanently running EC2 server, which spends most time idle", the team implemented this change: Move the schedule to EventBridge Scheduler with an appropriately scoped Lambda or supported task target. Which evidence confirms the intended behavior under test?

  1. A forced downstream failure follows tested compensation logic without duplicating completed orders
  2. The job executes at its configured schedule while no dedicated idle EC2 host is required
  3. A pilot demonstrates the chosen mainframe transformation path and acceptable business results
  4. Hot listing requests avoid origin recomputation while updates invalidate stale items within product SLAs

Explanation

Correct Answer

B:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. Managed scheduling can invoke short-lived compute without operating a permanent cron host. The acceptance condition is linked directly to the scenario: An application runs a small cron job on a permanently running EC2 server, which spends most time idle.

Incorrect Answers

A:

A forced downstream failure follows tested compensation logic without duplicating completed orders. However, this does not establish the required outcome: the job executes at its configured schedule while no dedicated idle EC2 host is required.

C:

A pilot demonstrates the chosen mainframe transformation path and acceptable business results. However, this does not establish the required outcome: the job executes at its configured schedule while no dedicated idle EC2 host is required.

D:

Hot listing requests avoid origin recomputation while updates invalidate stale items within product SLAs. However, this does not establish the required outcome: the job executes at its configured schedule while no dedicated idle EC2 host is required.

Question 696

For the enterprise requirement "A SQL Server estate must migrate to Amazon Aurora PostgreSQL despite vendor-specific T-SQL constructs", the team implemented this change: Use AWS Schema Conversion Tool or appropriate supported schema conversion assessment, then AWS DMS for data. Which test result proves this architecture satisfies its stated constraint?

  1. The proposed target design has documented permitted license use and tracked license utilization
  2. Critical converted schema objects and application queries work and data replication reconciles
  3. A pilot demonstrates the chosen mainframe transformation path and acceptable business results
  4. The Enterprise Support team uploads the approved data during its reserved session and matches end-to-end source and destination checksums

Explanation

Correct Answer

B:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. Heterogeneous database migrations require explicit schema and application compatibility work. The acceptance condition is linked directly to the scenario: A SQL Server estate must migrate to Amazon Aurora PostgreSQL despite vendor-specific T-SQL constructs.

Incorrect Answers

A:

The proposed target design has documented permitted license use and tracked license utilization. However, this does not establish the required outcome: critical converted schema objects and application queries work and data replication reconciles.

C:

A pilot demonstrates the chosen mainframe transformation path and acceptable business results. However, this does not establish the required outcome: critical converted schema objects and application queries work and data replication reconciles.

D:

The Enterprise Support team uploads the approved data during its reserved session and matches end-to-end source and destination checksums. However, this does not establish the required outcome: critical converted schema objects and application queries work and data replication reconciles.

Question 697

An architecture review recommends this solution: Review RI utilization, supported reservation sharing and regional family coverage before buying more. The motivating situation is: Several member accounts buy overlapping Reserved Instances, yet unused reservations remain in the organization. Which technical principle most strongly justifies this recommendation?

  1. Compute Optimizer estimates rightsizing opportunities subject to compatibility and workload validation
  2. RI coverage should be evaluated at consolidated billing scope where sharing is enabled
  3. Savings Plan decisions require evidence about coverage and utilization of eligible compute
  4. RDS Multi-AZ maintains standby capacity for high availability and managed failover

Explanation

Correct Answer

B:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Review RI utilization, supported reservation sharing and regional family coverage before buying more. The expected supporting evidence is: Discount usage improves with fewer unused reservation hours and measured baseline cost changes.

Incorrect Answers

A:

Instances remain oversized based only on purchase history rather than performance evidence. The stated evidence instead indicates: Teams purchase more RIs independently without measuring existing shared coverage.

C:

Capacity commitments are purchased solely from forecast without checking historical eligible use. The stated evidence instead indicates: Teams purchase more RIs independently without measuring existing shared coverage.

D:

The application is exposed to one database host or zonal compute failure. The stated evidence instead indicates: Teams purchase more RIs independently without measuring existing shared coverage.

Question 698

An architecture review recommends this solution: Configure and verify Route 53 failover records with endpoint health checks and explicit secondary routing. The motivating situation is: Two Regions are deployed but customer requests stay routed to the failed primary endpoint indefinitely. Which technical principle most strongly justifies this recommendation?

  1. SNS subscriber reliability relies on delivery retries and appropriately configured dead-letter destinations
  2. S3 Access Points can support distinct access policies for shared buckets
  3. RDS Multi-AZ maintains standby capacity for high availability and managed failover
  4. DNS failover needs a health-signal and routing policy that actually switches answers

Explanation

Correct Answer

D:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Configure and verify Route 53 failover records with endpoint health checks and explicit secondary routing. The expected supporting evidence is: After a simulated endpoint failure, new DNS queries return the secondary healthy Region.

Incorrect Answers

A:

Failed notifications disappear because no supported retry and DLQ design is in place. The stated evidence instead indicates: Passive regional copies exist without health-driven endpoint selection.

B:

One overbroad bucket-level policy grants both teams access to all data. The stated evidence instead indicates: Passive regional copies exist without health-driven endpoint selection.

C:

The application is exposed to one database host or zonal compute failure. The stated evidence instead indicates: Passive regional copies exist without health-driven endpoint selection.

Question 699

A professional architect is reviewing two independent workstreams. Requirement A: A container service must restore capacity after an AZ outage without manually replacing individual EC2 instances. Requirement B: A service currently stores a database password in deployment environment text and needs managed rotation without code updates. Which TWO recommendations jointly satisfy requirements A and B?

  1. Apply S3 Intelligent-Tiering with suitable monitoring and eligibility checks
  2. Configure S3 replication rules with correct versioning and KMS permissions for destination encrypted objects
  3. Run service tasks across multiple AZs with compatible load balancing and spare or scaling capacity
  4. Move the secret to AWS Secrets Manager and adopt controlled retrieval and rotation integration
  5. Use the applicable interface and gateway VPC endpoints and restrict endpoint policies and subnet routes as needed

Explanation

Correct Answers

C:

This action meets the independently stated requirement A: A container service must restore capacity after an AZ outage without manually replacing individual EC2 instances. Multi-AZ task placement and auto healing support zonal continuity for stateless applications. A direct acceptance check is: The load balancer continues serving from healthy remaining tasks during a forced zone failure.

D:

This action meets the independently stated requirement B: A service currently stores a database password in deployment environment text and needs managed rotation without code updates. Secrets Manager can store and rotate secrets with applications retrieving current authorized values. A direct acceptance check is: A rotation completes, the application authenticates with the new value, and old credentials are not exposed.

Incorrect Answers

A:

This action targets a different technical need: Unpredictably accessed objects are retained for a year, but no reliable access-frequency segmentation is known. It does not replace either required solution in A or B. S3 Intelligent-Tiering can move eligible objects among access tiers based on access frequency; verify the two stated requirements independently rather than accepting an unrelated change.

B:

This action targets a different technical need: Two Regions must retain independently encrypted object replicas to meet recovery requirements during a source Region failure. It does not replace either required solution in A or B. S3 encrypted object replication needs versioning and appropriate replication-role KMS authorization; verify the two stated requirements independently rather than accepting an unrelated change.

E:

This action targets a different technical need: An EC2 application requires private access to AWS Secrets Manager and S3 without traversing public network routes. It does not replace either required solution in A or B. VPC endpoints provide private connectivity to supported AWS services inside defined network and policy controls; verify the two stated requirements independently rather than accepting an unrelated change.

Question 700

For the enterprise requirement "Several member accounts buy overlapping Reserved Instances, yet unused reservations remain in the organization", the team implemented this change: Review RI utilization, supported reservation sharing and regional family coverage before buying more. Which outcome is the most meaningful acceptance test?

  1. Logs identify blocked and counted requests by rule so false positives can be evaluated
  2. Data-transfer charges drop while latency and resilience objectives still pass
  3. Discount usage improves with fewer unused reservation hours and measured baseline cost changes
  4. Approved orphaned volumes stop generating storage costs while protected volumes remain recoverable

Explanation

Correct Answer

C:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. RI coverage should be evaluated at consolidated billing scope where sharing is enabled. The acceptance condition is linked directly to the scenario: Several member accounts buy overlapping Reserved Instances, yet unused reservations remain in the organization.

Incorrect Answers

A:

Logs identify blocked and counted requests by rule so false positives can be evaluated. However, this does not establish the required outcome: discount usage improves with fewer unused reservation hours and measured baseline cost changes.

B:

Data-transfer charges drop while latency and resilience objectives still pass. However, this does not establish the required outcome: discount usage improves with fewer unused reservation hours and measured baseline cost changes.

D:

Approved orphaned volumes stop generating storage costs while protected volumes remain recoverable. However, this does not establish the required outcome: discount usage improves with fewer unused reservation hours and measured baseline cost changes.
