Amazon AWS Certified Solutions Architect - Professional SAP-C02 Practice Test 21

Question 200

In a production architecture assessment, the decisive constraint is: A production VPC needs inline stateful filtering of suspicious east-west and egress traffic. What is the most appropriate design under these constraints?

  1. Route relevant paths through AWS Network Firewall endpoints and rule groups
  2. Evaluate AWS Shield Advanced and appropriate protected resources
  3. Use GuardDuty threat findings and an approved isolation response procedure
  4. Attach AWS WAF rate-based rules to the protected API or CloudFront distribution

Explanation

Correct Answer

A:

Route relevant paths through AWS Network Firewall endpoints and rule groups. The choice follows from the service boundary and operational constraint stated in the scenario.

Incorrect Answers

B:

Evaluate AWS Shield Advanced and appropriate protected resources would address a different requirement: A public service must withstand large volumetric DDoS events and needs specialized incident support. Shield Advanced adds advanced DDoS capabilities and response support beyond standard protections.

C:

This alternative, Use GuardDuty threat findings and an approved isolation response procedure, is appropriate when A container workload shows suspicious outbound calls to a known command-and-control address. GuardDuty detects suspicious account and network behavior for investigation.

D:

For the separate situation A public API experiences HTTP request flooding and needs customizable managed request-rate blocking, Attach AWS WAF rate-based rules to the protected API or CloudFront distribution could be useful. AWS WAF filters HTTP-layer requests using configurable web ACL rules.

Question 201

A principal solutions architect reviews an AWS application dependency, the decisive constraint is: A restricted subnet must connect privately to Secrets Manager without a public NAT route. Which approach meets the stated objective with the least unnecessary complexity?

  1. Build a patched approved AMI and perform an Auto Scaling group instance refresh through the launch template
  2. Configure EKS Pod Identity for the service account and a least-privilege role
  3. Configure a DynamoDB gateway endpoint and relevant route-table associations
  4. Provision a Secrets Manager interface VPC endpoint with private DNS and access controls

Explanation

Correct Answer

D:

Provision a Secrets Manager interface VPC endpoint with private DNS and access controls. The choice follows from the service boundary and operational constraint stated in the scenario.

Incorrect Answers

A:

This alternative, Build a patched approved AMI and perform an Auto Scaling group instance refresh through the launch template, is appropriate when A regulated EC2 application uses immutable AMIs and must replace vulnerable hosts without in-place OS changes. Instance refresh replaces existing hosts with a tested immutable image instead of mutating production servers.

B:

For the separate situation A Kubernetes workload needs AWS API calls using scoped pod workload identity rather than node-wide access, Configure EKS Pod Identity for the service account and a least-privilege role could be useful. Per-pod identity narrows credentials compared with broadly privileged node roles.

C:

Configure a DynamoDB gateway endpoint and relevant route-table associations solves the related scenario A private subnet must reach DynamoDB without internet or NAT while following native DynamoDB endpoint routing; gateway endpoints provide AWS-routed DynamoDB service access for VPC sources.

Question 202

A business continuity assessment identifies the following constraint, the decisive constraint is: An internal event processing role requires access to an S3 bucket only from a particular VPC endpoint. What should the architect implement?

  1. Build a patched approved AMI and perform an Auto Scaling group instance refresh through the launch template
  2. Provision a Secrets Manager interface VPC endpoint with private DNS and access controls
  3. Configure a DynamoDB gateway endpoint and relevant route-table associations
  4. Combine a scoped role with an S3 bucket policy on the approved VPC endpoint

Explanation

Correct Answer

D:

Combine a scoped role with an S3 bucket policy on the approved VPC endpoint. VPC endpoint conditions constrain otherwise-valid credentials to an expected network path.

Incorrect Answers

A:

For the separate situation A regulated EC2 application uses immutable AMIs and must replace vulnerable hosts without in-place OS changes, Build a patched approved AMI and perform an Auto Scaling group instance refresh through the launch template could be useful. Instance refresh replaces existing hosts with a tested immutable image instead of mutating production servers.

B:

Provision a Secrets Manager interface VPC endpoint with private DNS and access controls solves the related scenario A restricted subnet must connect privately to Secrets Manager without a public NAT route; interface endpoints expose supported regional APIs through private addresses.

C:

Although Configure a DynamoDB gateway endpoint and relevant route-table associations can be valid when A private subnet must reach DynamoDB without internet or NAT while following native DynamoDB endpoint routing, it targets a different technical condition. Gateway endpoints provide AWS-routed DynamoDB service access for VPC sources.

Question 203

While designing a multi-Region AWS solution, the decisive constraint is: A private subnet must reach DynamoDB without internet or NAT while following native DynamoDB endpoint routing. Which technical choice resolves the stated issue?

  1. Provision a Secrets Manager interface VPC endpoint with private DNS and access controls
  2. Combine a scoped role with an S3 bucket policy on the approved VPC endpoint
  3. Configure a DynamoDB gateway endpoint and relevant route-table associations
  4. Configure EKS Pod Identity for the service account and a least-privilege role

Explanation

Correct Answer

C:

Configure a DynamoDB gateway endpoint and relevant route-table associations. Gateway endpoints provide AWS-routed DynamoDB service access for VPC sources.

Incorrect Answers

A:

Provision a Secrets Manager interface VPC endpoint with private DNS and access controls solves the related scenario A restricted subnet must connect privately to Secrets Manager without a public NAT route; interface endpoints expose supported regional APIs through private addresses.

B:

Although Combine a scoped role with an S3 bucket policy on the approved VPC endpoint can be valid when An internal event processing role requires access to an S3 bucket only from a particular VPC endpoint, it targets a different technical condition. VPC endpoint conditions constrain otherwise-valid credentials to an expected network path.

D:

This alternative, Configure EKS Pod Identity for the service account and a least-privilege role, is appropriate when A Kubernetes workload needs AWS API calls using scoped pod workload identity rather than node-wide access. Per-pod identity narrows credentials compared with broadly privileged node roles.

Question 204

During an infrastructure cost and reliability assessment, the decisive constraint is: A regulated EC2 application uses immutable AMIs and must replace vulnerable hosts without in-place OS changes. What is the most defensible implementation decision?

  1. Configure a DynamoDB gateway endpoint and relevant route-table associations
  2. Build a patched approved AMI and perform an Auto Scaling group instance refresh through the launch template
  3. Configure EKS Pod Identity for the service account and a least-privilege role
  4. Provision a Secrets Manager interface VPC endpoint with private DNS and access controls

Explanation

Correct Answer

B:

Interface endpoints expose supported regional APIs through private addresses.

Question 205

An engineering organization has identified this operational requirement, the decisive constraint is: A Kubernetes workload needs AWS API calls using scoped pod workload identity rather than node-wide access. Which architecture decision most directly satisfies the requirement?

  1. Build a patched approved AMI and perform an Auto Scaling group instance refresh through the launch template
  2. Configure EKS Pod Identity for the service account and a least-privilege role
  3. Combine a scoped role with an S3 bucket policy on the approved VPC endpoint
  4. Configure a DynamoDB gateway endpoint and relevant route-table associations

Explanation

Correct Answer

B:

Configure EKS Pod Identity for the service account and a least-privilege role. Per-pod identity narrows credentials compared with broadly privileged node roles.

Incorrect Answers

Question 206

A team is choosing AWS services for a specific workload, the decisive constraint is: A checkout API must accept orders during temporary downstream payment-processor outages. Which recommendation best addresses the actual bottleneck?

  1. Use SQS FIFO with explicit message group IDs and deduplication handling
  2. Buffer accepted work in Amazon SQS and retry with idempotent consumers
  3. Configure an SQS dead-letter queue with a sensible maxReceiveCount and remediation process
  4. Make processing idempotent and size the SQS visibility timeout for realistic execution

Explanation

Correct Answer

B:

Buffer accepted work in Amazon SQS and retry with idempotent consumers. Durable queues absorb downstream downtime without keeping synchronous HTTP requests open.

Incorrect Answers

A:

For the separate situation An ordered payment event stream must preserve messages within the same order key and avoid duplicates in supported conditions, Use SQS FIFO with explicit message group IDs and deduplication handling could be useful. FIFO queues support ordered processing per group and deduplication semantics.

C:

Although Configure an SQS dead-letter queue with a sensible maxReceiveCount and remediation process can be valid when A queue consumer repeatedly fails on the same malformed message and blocks normal progress, it targets a different technical condition. DLQs isolate poison messages from repeated normal processing.

D:

Make processing idempotent and size the SQS visibility timeout for realistic execution would address a different requirement: Workers receive the same message again after a visibility timeout expires. Standard SQS provides at-least-once delivery and can redeliver unfinished messages.

Question 207

During an AWS global infrastructure design review, the decisive constraint is: A queue consumer repeatedly fails on the same malformed message and blocks normal progress. Which approach meets the stated objective with the least unnecessary complexity?

  1. Configure an SQS dead-letter queue with a sensible maxReceiveCount and remediation process
  2. Publish to an SNS topic with separate SQS subscriptions for each consumer
  3. Make processing idempotent and size the SQS visibility timeout for realistic execution
  4. Use SQS FIFO with explicit message group IDs and deduplication handling

Explanation

Correct Answer

A:

Configure an SQS dead-letter queue with a sensible maxReceiveCount and remediation process. DLQs isolate poison messages from repeated normal processing.

Incorrect Answers

B:

Although Publish to an SNS topic with separate SQS subscriptions for each consumer can be valid when An inventory event must fan out independently to analytics, billing and notification consumers, it targets a different technical condition. SNS-to-SQS fanout preserves independent subscriber processing and retries.

C:

Make processing idempotent and size the SQS visibility timeout for realistic execution would address a different requirement: Workers receive the same message again after a visibility timeout expires. Standard SQS provides at-least-once delivery and can redeliver unfinished messages.

D:

This alternative, Use SQS FIFO with explicit message group IDs and deduplication handling, is appropriate when An ordered payment event stream must preserve messages within the same order key and avoid duplicates in supported conditions. FIFO queues support ordered processing per group and deduplication semantics.
