Question 530

An enterprise architecture team faces this design requirement: A public S3 bucket and KMS key unexpectedly trust principals outside the company's AWS organization. What should the solutions architect recommend?

  1. Enable AWS WAF logging to an appropriate destination with sensitive-data handling and analyze matched rules
  2. Design a supported Multi-AZ deployment with reconnection handling and execute maintenance drills
  3. Run IAM Access Analyzer external-access findings scoped to the organization and fix the exact resource policies
  4. Use S3 Access Points or carefully scoped bucket policies to isolate each team's required object prefixes

Explanation

Correct Answer

C:

Access Analyzer detects eligible resource trust outside its zone of trust. The required architecture outcome is: A public S3 bucket and KMS key unexpectedly trust principals outside the company's AWS organization. Validate this choice by checking that Cross-account access findings identify external principals and clear only when permissions are corrected.

Incorrect Answers

A:

WAF rules are deployed without visibility into which requests they affect. The specific problem here is that resource-based trust was not evaluated beyond local IAM identity permission reports.

B:

The application is exposed to one database host or zonal compute failure. The specific problem here is that resource-based trust was not evaluated beyond local IAM identity permission reports.

D:

One overbroad bucket-level policy grants both teams access to all data. The specific problem here is that resource-based trust was not evaluated beyond local IAM identity permission reports.

Question 531

For the enterprise requirement "A central audit account needs immutable delivery of logs from all workload accounts and Regions", the team implemented this change: Use organization-wide CloudTrail and central log storage with restrictive bucket access and retention controls. Which outcome is the most meaningful acceptance test?

  1. A new workload account's API activity appears in the central log bucket and member administrators cannot erase it
  2. Central compliance dashboards include resource findings from configured participating accounts and Regions
  3. A synthetic or observed unusual cost pattern appears in anomaly alerts with impacted spend drivers
  4. Events from a test member account reach the central incident workflow and unauthorized senders are rejected

Explanation

Correct Answer

A:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. An organization trail and protected storage form a centralized account-wide auditing design. The acceptance condition is linked directly to the scenario: A central audit account needs immutable delivery of logs from all workload accounts and Regions.

Incorrect Answers

B:

Central compliance dashboards include resource findings from configured participating accounts and Regions. However, this does not establish the required outcome: a new workload account's API activity appears in the central log bucket and member administrators cannot erase it.

C:

A synthetic or observed unusual cost pattern appears in anomaly alerts with impacted spend drivers. However, this does not establish the required outcome: a new workload account's API activity appears in the central log bucket and member administrators cannot erase it.

D:

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 new workload account's API activity appears in the central log bucket and member administrators cannot erase it.

Question 532

An enterprise architecture team faces this design requirement: A distributed transaction takes too long but the application log contains no per-hop timing breakdown. What design change should the team implement?

  1. Move the suitable multi-step orchestration into Step Functions with named states, bounded retries and error paths
  2. Pair an AWS Config detection rule with controlled Systems Manager Automation remediation and change safeguards
  3. Instrument eligible application components with AWS X-Ray tracing or supported distributed tracing correlation
  4. Use S3 Access Points or carefully scoped bucket policies to isolate each team's required object prefixes

Explanation

Correct Answer

C:

Distributed tracing provides span-level request-path visibility across instrumented services. The required architecture outcome is: A distributed transaction takes too long but the application log contains no per-hop timing breakdown. Validate this choice by checking that A test transaction shows the slow downstream dependency and request trace span timing.

Incorrect Answers

A:

Untracked imperative orchestration repeats previous side effects after transient failures. The specific problem here is that uncorrelated logs hide where the end-to-end latency accumulates.

B:

Config findings are left as unactioned notifications while risky drift remains exposed. The specific problem here is that uncorrelated logs hide where the end-to-end latency accumulates.

D:

One overbroad bucket-level policy grants both teams access to all data. The specific problem here is that uncorrelated logs hide where the end-to-end latency accumulates.

Question 533

A deployed environment still does not meet the original requirement: Two acquired subsidiaries have overlapping RFC1918 VPC CIDRs but must exchange traffic with a shared integration endpoint. Which root cause is most consistent with the observation?

  1. Separate point-to-point VPC peering connections lack transitive routing and are difficult to govern at scale
  2. Overlapping network prefixes make ordinary VPC peering route selection ambiguous
  3. The remote principal has S3 object access but lacks required key-policy and IAM decrypt permission
  4. There is no independently functioning VPN path when private connectivity goes down

Explanation

Correct Answer

B:

This is the technical design error aligned with the unmet requirement. Overlapping address spaces require translation or service-level isolation rather than simple routed peering. The appropriate correction is: Introduce a centrally managed translation or proxy layer with nonoverlapping service endpoints rather than directly peering overlapping networks. The control should then be tested by verifying that Traffic uses translated unique endpoint addresses and return packets reach the original client correctly.

Incorrect Answers

A:

Separate point-to-point VPC peering connections lack transitive routing and are difficult to govern at scale. The stated evidence instead indicates: Overlapping network prefixes make ordinary VPC peering route selection ambiguous.

C:

The remote principal has S3 object access but lacks required key-policy and IAM decrypt permission. The stated evidence instead indicates: Overlapping network prefixes make ordinary VPC peering route selection ambiguous.

D:

There is no independently functioning VPN path when private connectivity goes down. The stated evidence instead indicates: Overlapping network prefixes make ordinary VPC peering route selection ambiguous.

Question 534

An architecture review recommends this solution: Configure organization-wide GuardDuty administration with supported automatic enrollment and region strategy. The motivating situation is: The security team manages GuardDuty separately in 50 accounts and misses newly created member accounts. Which architectural reasoning is most accurate for the choice?

  1. Security Hub consolidates security posture and findings from participating services
  2. Central GuardDuty administration supports ongoing multi-account detection enrollment
  3. Blue-green promotion protects a known-good environment until replacement quality is established
  4. AWS Config checks configuration changes against evaluable rules and supports managed remediation actions

Explanation

Correct Answer

B:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Configure organization-wide GuardDuty administration with supported automatic enrollment and region strategy. The expected supporting evidence is: Existing and new participating accounts report eligible findings to the delegated administrator.

Incorrect Answers

A:

Findings remain siloed in local account consoles and cannot be triaged centrally. The stated evidence instead indicates: Threat detection remains inconsistently deployed across member accounts and Regions.

C:

In-place mass deployment removed rollback capacity before verifying the new version. The stated evidence instead indicates: Threat detection remains inconsistently deployed across member accounts and Regions.

D:

Static security policy documents are not technically enforced against resource drift. The stated evidence instead indicates: Threat detection remains inconsistently deployed across member accounts and Regions.

Question 535

An enterprise architecture team faces this design requirement: An internet service must survive one Availability Zone failure while adjusting to fluctuating weekday usage. What is the most appropriate design for this workload?

  1. Evaluate AWS Shield Advanced with supported resource protection and runbooks alongside layered edge controls
  2. Use an Application Load Balancer with Auto Scaling groups spanning multiple AZs and health checks
  3. Configure EventBridge archives and event replay with selection patterns and measured retention
  4. Deploy a supported RDS Multi-AZ configuration and verify connection retry and DNS handling

Explanation

Correct Answer

B:

Multi-AZ target placement and health-driven scaling provide elastic zonal resilience. The required architecture outcome is: An internet service must survive one Availability Zone failure while adjusting to fluctuating weekday usage. Validate this choice by checking that Terminating all instances in one zone leaves healthy targets and Auto Scaling replaces lost capacity.

Incorrect Answers

A:

Basic infrastructure availability controls were mistaken for managed advanced DDoS response workflow. The specific problem here is that instance capacity is pinned to one zone with no automated target recovery.

C:

No event archive exists to replay notifications that failed during downstream processing. The specific problem here is that instance capacity is pinned to one zone with no automated target recovery.

D:

Single-AZ database storage and compute are a single zonal failure domain. The specific problem here is that instance capacity is pinned to one zone with no automated target recovery.

Question 536

A deployed environment still does not meet the original requirement: Hundreds of EC2 hosts need scheduled patch windows with evidence of patch compliance and approved maintenance boundaries. Which missing control accounts for the continuing issue?

  1. Patch application is manual and lacks consistent baseline selection and change evidence
  2. Standard short-lived backups cannot recover the exact chosen accidental-update point
  3. Engineers measure host utilization but not the outcomes experienced by users
  4. Uncorrelated logs hide where the end-to-end latency accumulates

Explanation

Correct Answer

A:

This is the technical design error aligned with the unmet requirement. Systems Manager supports fleet patching with centralized baselines and maintenance windows. The appropriate correction is: Use Systems Manager Patch Manager with patch baselines and maintenance-window runbooks. The control should then be tested by verifying that Compliance reports show applied baselines and chosen hosts patched only during approved windows.

Incorrect Answers

B:

Standard short-lived backups cannot recover the exact chosen accidental-update point. The stated evidence instead indicates: Patch application is manual and lacks consistent baseline selection and change evidence.

C:

Engineers measure host utilization but not the outcomes experienced by users. The stated evidence instead indicates: Patch application is manual and lacks consistent baseline selection and change evidence.

D:

Uncorrelated logs hide where the end-to-end latency accumulates. The stated evidence instead indicates: Patch application is manual and lacks consistent baseline selection and change evidence.

Question 537

An enterprise architecture team faces this design requirement: An EKS service experiences 503 errors during rolling updates because pods accept traffic before dependencies initialize. What is the most appropriate design for this workload?

  1. Configure readiness probes, deployment surge policy and graceful termination semantics
  2. Build CloudWatch operational dashboards with service-specific metrics, structured logging, and correlation identifiers
  3. Schedule automated and manual AWS Backup restore testing into an isolated validation environment
  4. Design a supported Multi-AZ deployment with reconnection handling and execute maintenance drills

Explanation

Correct Answer

A:

Readiness and graceful termination controls reduce errors during normal rolling changes. The required architecture outcome is: An EKS service experiences 503 errors during rolling updates because pods accept traffic before dependencies initialize. Validate this choice by checking that Load tests show traffic reaches only ready pods and terminating pods finish work before deletion.

Incorrect Answers

B:

Metrics and logs are not organized into actionable per-service operational signals. The specific problem here is that kubernetes deployment treats process startup as adequate evidence of request readiness.

C:

Snapshot creation is mistaken for proof the application can actually be restored. The specific problem here is that kubernetes deployment treats process startup as adequate evidence of request readiness.

D:

The application is exposed to one database host or zonal compute failure. The specific problem here is that kubernetes deployment treats process startup as adequate evidence of request readiness.

Question 538

For the enterprise requirement "A multi-account organization must prevent member accounts from disabling mandatory CloudTrail trails even when local administrators hold broad IAM policies", the team implemented this change: Apply a targeted Organizations service control policy denying prohibited CloudTrail disablement actions in affected OUs. What observed result would demonstrate successful delivery of the requested capability?

  1. An administrator's disable request is denied while an authorized central management path remains available
  2. Every enrolled account produces expected trail events in the security account and workloads cannot delete retained logs
  3. Eligible accounts create scheduled recovery points according to policies and restores are tested
  4. The consumer role reads approved encrypted objects but cannot decrypt other protected datasets

Explanation

Correct Answer

A:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. Service control policies set permission ceilings for member account principals and cannot grant access themselves. The acceptance condition is linked directly to the scenario: A multi-account organization must prevent member accounts from disabling mandatory CloudTrail trails even when local administrators hold broad IAM policies.

Incorrect Answers

B:

Every enrolled account produces expected trail events in the security account and workloads cannot delete retained logs. However, this does not establish the required outcome: an administrator's disable request is denied while an authorized central management path remains available.

C:

Eligible accounts create scheduled recovery points according to policies and restores are tested. However, this does not establish the required outcome: an administrator's disable request is denied while an authorized central management path remains available.

D:

The consumer role reads approved encrypted objects but cannot decrypt other protected datasets. However, this does not establish the required outcome: an administrator's disable request is denied while an authorized central management path remains available.

Question 539

An enterprise architecture team faces this design requirement: Two Regions are deployed but customer requests stay routed to the failed primary endpoint indefinitely. Which architecture decision best meets that precise requirement?

  1. Configure the supported subscription delivery policy, retries and dead-letter queue where applicable
  2. Configure and verify Route 53 failover records with endpoint health checks and explicit secondary routing
  3. Introduce a blue-green deployment strategy with health alarms and traffic rollback
  4. Inventory unattached EBS volumes and delete or archive approved volumes after snapshot and ownership checks

Explanation

Correct Answer

B:

DNS failover needs a health-signal and routing policy that actually switches answers. The required architecture outcome is: Two Regions are deployed but customer requests stay routed to the failed primary endpoint indefinitely. Validate this choice by checking that 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 specific problem here is that passive regional copies exist without health-driven endpoint selection.

C:

In-place mass deployment removed rollback capacity before verifying the new version. The specific problem here is that passive regional copies exist without health-driven endpoint selection.

D:

Unattached volumes are treated as free merely because they are not mounted. The specific problem here is that passive regional copies exist without health-driven endpoint selection.

Question 540

An architecture review recommends this solution: Evaluate on-demand capacity or auto scaling where appropriate and check hot partition keys. The motivating situation is: A DynamoDB table receives unpredictable read request bursts causing throttling during seasonal peaks. Which principle would a reviewer use to defend this design?

  1. Placement and traffic pattern matter to data transfer costs as much as raw compute prices
  2. Enhanced networking capabilities require compatible instance types and operating-system drivers
  3. CloudFront Origin Shield can consolidate cache misses through an additional regional layer
  4. DynamoDB throughput requires sufficient mode capacity and key-distribution design

Explanation

Correct Answer

D:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Evaluate on-demand capacity or auto scaling where appropriate and check hot partition keys. The expected supporting evidence is: Burst replay avoids throttling while partition-level demand remains within supported constraints.

Incorrect Answers

A:

Workload service calls repeatedly cross paid network boundaries without quantified need. The stated evidence instead indicates: Capacity planning ignores demand spikes or hot keys that concentrate requests.

B:

Unsupported drivers or unsuitable instance networking features cap throughput. The stated evidence instead indicates: Capacity planning ignores demand spikes or hot keys that concentrate requests.

C:

Misses from different edge caches repeatedly burden the same origin. The stated evidence instead indicates: Capacity planning ignores demand spikes or hot keys that concentrate requests.
