Amazon AWS Certified Solutions Architect - Professional SAP-C02 Practice Test 82

Question 810

A deployed environment still does not meet the original requirement: An Application Load Balancer intermittently forwards traffic to unhealthy containers after their readiness endpoint fails. What was most likely overlooked in the original design?

  1. The application is exposed to one database host or zonal compute failure
  2. Health checks use an unrelated always-200 endpoint that does not reflect the service readiness
  3. Administrators run sensitive maintenance scripts with no enforced approval or trail
  4. Kubernetes deployment treats process startup as adequate evidence of request readiness

Explanation

Correct Answer

B:

This is the technical design error aligned with the unmet requirement. Load balancer health checks must match actual application readiness rather than superficial liveness. The appropriate correction is: Correct target group health checks and deployment deregistration timing based on actual readiness semantics. The control should then be tested by verifying that Unhealthy containers leave active target selection promptly while healthy targets continue receiving requests.

Incorrect Answers

A:

The application is exposed to one database host or zonal compute failure. The stated evidence instead indicates: Health checks use an unrelated always-200 endpoint that does not reflect the service readiness.

C:

Administrators run sensitive maintenance scripts with no enforced approval or trail. The stated evidence instead indicates: Health checks use an unrelated always-200 endpoint that does not reflect the service readiness.

D:

Kubernetes deployment treats process startup as adequate evidence of request readiness. The stated evidence instead indicates: Health checks use an unrelated always-200 endpoint that does not reflect the service readiness.

Question 811

An architecture review recommends this solution: Publish permitted events across account boundaries to a central EventBridge event bus with explicit resource policy. The motivating situation is: Audit findings in application accounts must trigger an event-driven central incident triage workflow. What principle supports the selected implementation?

  1. Organizational units help assign governance boundaries to related member accounts
  2. Service-specific delegated administration provides controlled cross-account security operations
  3. EventBridge cross-account routing requires rules and resource-based permissions
  4. Durable queues decouple intake availability from downstream processing failures

Explanation

Correct Answer

C:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Publish permitted events across account boundaries to a central EventBridge event bus with explicit resource policy. The expected supporting evidence is: Events from a test member account reach the central incident workflow and unauthorized senders are rejected.

Incorrect Answers

A:

All accounts share one indiscriminate service-control policy despite different risk profiles. The stated evidence instead indicates: Events remain confined to local account buses because cross-account bus authorization is absent.

B:

Management-account-only operations were mistaken for necessary daily centralized security administration. The stated evidence instead indicates: Events remain confined to local account buses because cross-account bus authorization is absent.

D:

Synchronous request-to-database coupling loses or rejects work whenever the database is unavailable. The stated evidence instead indicates: Events remain confined to local account buses because cross-account bus authorization is absent.

Question 812

A professional architect is reviewing two independent workstreams. Requirement A: A database team purchased oversized io2 EBS performance when measured throughput is far below its actual needs. Requirement B: Service owners cannot separate API traffic incidents from infrastructure incidents across ten microservices. Which TWO architecture changes cover both acceptance criteria?

  1. Build CloudWatch operational dashboards with service-specific metrics, structured logging, and correlation identifiers
  2. Pair an AWS Config detection rule with controlled Systems Manager Automation remediation and change safeguards
  3. Use Cost Optimization Hub for supported consolidated recommendations and track deduplicated savings
  4. Enable and test DynamoDB point-in-time recovery for the table and recovery runbook
  5. Benchmark throughput and latency, then evaluate a supported gp3 volume where required performance fits

Explanation

Correct Answers

A:

This action meets the independently stated requirement B: Service owners cannot separate API traffic incidents from infrastructure incidents across ten microservices. Meaningful dashboards align telemetry with system service boundaries and indicators. A direct acceptance check is: An incident view identifies the affected service and response latency rather than just total fleet CPU.

E:

This action meets the independently stated requirement A: A database team purchased oversized io2 EBS performance when measured throughput is far below its actual needs. EBS volume-class selection should follow measured IO and durability requirements. A direct acceptance check is: Tested gp3 configuration meets IO SLOs at lower monthly storage and provisioned-performance cost.

Incorrect Answers

B:

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.

C:

This action targets a different technical need: Finance collects optimizer suggestions from Compute Optimizer, Trusted Advisor and cost dashboards but counts the same recommendation more than once. It does not replace either required solution in A or B. Consolidated savings recommendations should not be summed blindly across sources; verify the two stated requirements independently rather than accepting an unrelated change.

D:

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.

Question 813

An architecture review recommends this solution: Use Compute Optimizer and validate monitoring data before right-sizing eligible instances. The motivating situation is: Dozens of overprovisioned EC2 instances need evidence-based CPU and memory sizing recommendations before changing families. Which consideration makes this solution preferable to the original approach?

  1. Cost Anomaly Detection learns spending patterns and flags unusual expenditures
  2. EventBridge archives support bounded replay of previously captured events
  3. Compute Optimizer uses resource metrics and recommendations but must be checked against workload SLOs
  4. S3 Storage Lens supports visibility into storage activity and efficiency metrics

Explanation

Correct Answer

C:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Use Compute Optimizer and validate monitoring data before right-sizing eligible instances. The expected supporting evidence is: Tested resized instances meet p95 latency goals while recommended savings are observed.

Incorrect Answers

A:

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

B:

No archive or retention mechanism was configured before the subscriber outage. The stated evidence instead indicates: Instances were resized from average CPU alone despite memory or traffic constraints.

D:

Teams have only aggregate bills and cannot locate the source of inefficient storage usage. The stated evidence instead indicates: Instances were resized from average CPU alone despite memory or traffic constraints.

Question 814

A deployed environment still does not meet the original requirement: A shared S3 estate has ballooning noncurrent versions, incomplete multipart uploads and forgotten small objects. Which failure mechanism should the team correct?

  1. Premium IOPS are maintained without evidence of workload needing them
  2. Teams purchase more RIs independently without measuring existing shared coverage
  3. Console edits accumulate because no one compares deployed state with infrastructure definitions
  4. Dormant storage versions and partial uploads accumulate without inventory or lifecycle governance

Explanation

Correct Answer

D:

This is the technical design error aligned with the unmet requirement. S3 analytics and lifecycle rules target recoverable storage waste when retention is respected. The appropriate correction is: Use S3 Storage Lens or inventory analytics and implement targeted lifecycle cleanup rules. The control should then be tested by verifying that Identified buckets show smaller unnecessary version and multipart storage after retention-safe cleanup.

Incorrect Answers

A:

Premium IOPS are maintained without evidence of workload needing them. The stated evidence instead indicates: Dormant storage versions and partial uploads accumulate without inventory or lifecycle governance.

B:

Teams purchase more RIs independently without measuring existing shared coverage. The stated evidence instead indicates: Dormant storage versions and partial uploads accumulate without inventory or lifecycle governance.

C:

Console edits accumulate because no one compares deployed state with infrastructure definitions. The stated evidence instead indicates: Dormant storage versions and partial uploads accumulate without inventory or lifecycle governance.

Question 815

An architecture review recommends this solution: Use AWS Schema Conversion Tool or appropriate supported schema conversion assessment, then AWS DMS for data. The motivating situation is: A SQL Server estate must migrate to Amazon Aurora PostgreSQL despite vendor-specific T-SQL constructs. Which consideration makes this solution preferable to the original approach?

  1. A centralized migration tracking layer supports coordination across application teams
  2. Heterogeneous database migrations require explicit schema and application compatibility work
  3. Mainframe migrations need purpose-built assessment and conversion or replatform planning
  4. Homogeneous migrations usually focus on data replication, compatibility details and cutover rather than engine-language rewrite

Explanation

Correct Answer

B:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Use AWS Schema Conversion Tool or appropriate supported schema conversion assessment, then AWS DMS for data. The expected supporting evidence is: Critical converted schema objects and application queries work and data replication reconciles.

Incorrect Answers

A:

Migration tasks are tracked in separate team documents with no common portfolio state. The stated evidence instead indicates: Replicating table data alone does not translate incompatible source SQL constructs.

C:

Mainframe batch and transaction semantics were treated as if they were ordinary Linux workloads. The stated evidence instead indicates: Replicating table data alone does not translate incompatible source SQL constructs.

D:

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

Question 816

For the enterprise requirement "Capacity planners need a monthly cost forecast that reflects a new Region and expected usage growth before deployment", the team implemented this change: Model expected service usage in AWS Pricing Calculator and compare results against historical billing trends. Which evidence confirms the intended behavior under test?

  1. Proposed architecture cost estimates can be traced to entered quantities and forecast assumptions
  2. Eligible compute charges reflect the planned commitment discount and remaining coverage is visible
  3. A new workload account's API activity appears in the central log bucket and member administrators cannot erase it
  4. Finance sees prioritized savings opportunities and can distinguish overlapping cost recommendations

Explanation

Correct Answer

A:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. Architecture forecasts require explicit usage assumptions rather than extrapolation without design changes. The acceptance condition is linked directly to the scenario: Capacity planners need a monthly cost forecast that reflects a new Region and expected usage growth before deployment.

Incorrect Answers

B:

Eligible compute charges reflect the planned commitment discount and remaining coverage is visible. However, this does not establish the required outcome: proposed architecture cost estimates can be traced to entered quantities and forecast assumptions.

C:

A new workload account's API activity appears in the central log bucket and member administrators cannot erase it. However, this does not establish the required outcome: proposed architecture cost estimates can be traced to entered quantities and forecast assumptions.

D:

Finance sees prioritized savings opportunities and can distinguish overlapping cost recommendations. However, this does not establish the required outcome: proposed architecture cost estimates can be traced to entered quantities and forecast assumptions.

Question 817

For the enterprise requirement "A public S3 bucket and KMS key unexpectedly trust principals outside the company's AWS organization", the team implemented this change: Run IAM Access Analyzer external-access findings scoped to the organization and fix the exact resource policies. What observed result would demonstrate successful delivery of the requested capability?

  1. Compliance reports show applied baselines and chosen hosts patched only during approved windows
  2. The actor, source and changed policy action appear in audit events from the affected account
  3. Cross-account access findings identify external principals and clear only when permissions are corrected
  4. Security Hub centrally displays eligible standardized findings with source context preserved

Explanation

Correct Answer

C:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. Access Analyzer detects eligible resource trust outside its zone of trust. The acceptance condition is linked directly to the scenario: A public S3 bucket and KMS key unexpectedly trust principals outside the company's AWS organization.

Incorrect Answers

A:

Compliance reports show applied baselines and chosen hosts patched only during approved windows. However, this does not establish the required outcome: cross-account access findings identify external principals and clear only when permissions are corrected.

B:

The actor, source and changed policy action appear in audit events from the affected account. However, this does not establish the required outcome: cross-account access findings identify external principals and clear only when permissions are corrected.

D:

Security Hub centrally displays eligible standardized findings with source context preserved. However, this does not establish the required outcome: cross-account access findings identify external principals and clear only when permissions are corrected.

Question 818

An architecture review recommends this solution: Export AWS Cost and Usage Reports to S3 and query them with Athena or a billing data analysis workflow. The motivating situation is: An enterprise wants line-item chargeback for data transfer and service usage across hundreds of accounts. Why is this architecture appropriate for the described workload?

  1. Architecture forecasts require explicit usage assumptions rather than extrapolation without design changes
  2. The Cost and Usage Report provides detailed billing facts for accountable cost analysis
  3. AWS RAM can share supported resources while ownership remains in a central account
  4. AWS Budgets supports spend targets and notifications on actual or forecasted cost

Explanation

Correct Answer

B:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Export AWS Cost and Usage Reports to S3 and query them with Athena or a billing data analysis workflow. The expected supporting evidence is: Finance can reconcile detailed usage line items to accounts and cost categories.

Incorrect Answers

A:

Previous-month charges were presented as accurate forecasts for an expanded future footprint. The stated evidence instead indicates: Summary monthly bills lack the resource-level usage detail needed for chargeback.

C:

Each application team is provisioning its own disconnected backbone gateway. The stated evidence instead indicates: Summary monthly bills lack the resource-level usage detail needed for chargeback.

D:

The team relies exclusively on retrospective end-of-month billing statements. The stated evidence instead indicates: Summary monthly bills lack the resource-level usage detail needed for chargeback.

Question 819

A professional architect is reviewing two independent workstreams. Requirement A: A platform team deploys the same baseline IAM roles and configuration stacks into 70 governed member accounts. Requirement B: Large fault-tolerant batch analytics jobs can be interrupted and resumed while the team pays full on-demand prices. Which TWO controls should be used together for these separate scenarios?

  1. Publish a Lambda version and configure weighted alias routing with deployment alarms
  2. Configure S3 lifecycle transitions to a suitable archival storage class and test retrieval times
  3. Use EC2 Spot capacity with checkpointing and interruption-aware retry mechanisms
  4. Implement a tested backup-and-restore disaster recovery pattern with documented recovery runbooks
  5. Use CloudFormation StackSets with the appropriate organization deployment permissions and guarded account or OU targeting

Explanation

Correct Answers

C:

This action meets the independently stated requirement B: Large fault-tolerant batch analytics jobs can be interrupted and resumed while the team pays full on-demand prices. Spot Instances optimize interruptible capacity costs when jobs tolerate reclaim events. A direct acceptance check is: A simulated interruption causes bounded rework and lowers total compute cost without losing final results.

E:

This action meets the independently stated requirement A: A platform team deploys the same baseline IAM roles and configuration stacks into 70 governed member accounts. CloudFormation StackSets manages stack instances across accounts and Regions from a controlled template. A direct acceptance check is: A newly added target account receives the intended stack instances while an excluded OU does not.

Incorrect Answers

A:

This action targets a different technical need: A Lambda-backed API team wants to expose only ten percent of traffic to a new function revision before promoting it. It does not replace either required solution in A or B. Lambda aliases support weighted traffic between published versions with monitored promotion; verify the two stated requirements independently rather than accepting an unrelated change.

B:

This action targets a different technical need: A compliance dataset is rarely accessed after 90 days but must remain recoverable with several-hour retrieval tolerance. It does not replace either required solution in A or B. Lifecycle transitions reduce storage expense only if retrieval and minimum-duration constraints fit; verify the two stated requirements independently rather than accepting an unrelated change.

D:

This action targets a different technical need: A noncritical archive service has a 24-hour RTO and may restore its configuration and data from protected backups. It does not replace either required solution in A or B. Backup-and-restore DR suits longer RTO targets when restore execution is practiced; verify the two stated requirements independently rather than accepting an unrelated change.

Question 820

For the enterprise requirement "Several accounts have steady EC2 and Fargate spend and need a commitment that applies to qualifying compute usage flexibly", the team implemented this change: Analyze commitments then purchase an appropriate Compute Savings Plan based on supported usage coverage. What observed result would demonstrate successful delivery of the requested capability?

  1. Consumer instances reach only the approved PrivateLink service while unrelated provider subnets remain unreachable
  2. Dashboards identify targeted buckets with abnormal storage patterns and lifecycle candidates
  3. Tested resized instances meet p95 latency goals while recommended savings are observed
  4. Eligible compute charges reflect the planned commitment discount and remaining coverage is visible

Explanation

Correct Answer

D:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. Compute Savings Plans apply eligible usage discounts across supported services and configurations. The acceptance condition is linked directly to the scenario: Several accounts have steady EC2 and Fargate spend and need a commitment that applies to qualifying compute usage flexibly.

Incorrect Answers

A:

Consumer instances reach only the approved PrivateLink service while unrelated provider subnets remain unreachable. However, this does not establish the required outcome: eligible compute charges reflect the planned commitment discount and remaining coverage is visible.

B:

Dashboards identify targeted buckets with abnormal storage patterns and lifecycle candidates. However, this does not establish the required outcome: eligible compute charges reflect the planned commitment discount and remaining coverage is visible.

C:

Tested resized instances meet p95 latency goals while recommended savings are observed. However, this does not establish the required outcome: eligible compute charges reflect the planned commitment discount and remaining coverage is visible.
