Amazon AWS Certified Solutions Architect - Professional SAP-C02 Practice Test 23

Question 220

A deployed environment still does not meet the original requirement: Compliance requires protected organization-wide API activity logs to flow into a centralized security account with controlled deletion. Which root cause is most consistent with the observation?

  1. Resource tags were never activated as billing cost allocation dimensions
  2. Disjoint local-account trails leave central auditors with incomplete visibility
  3. The remote principal has S3 object access but lacks required key-policy and IAM decrypt permission
  4. Individual Security Hub instances were not centrally delegated or aggregated

Explanation

Correct Answer

B:

This is the technical design error aligned with the unmet requirement. AWS Organizations trails centralize multi-account CloudTrail logging when storage access is secured. The appropriate correction is: Configure an organization trail delivered to a protected central S3 bucket with appropriate key and bucket controls. The control should then be tested by verifying that Every enrolled account produces expected trail events in the security account and workloads cannot delete retained logs.

Incorrect Answers

A:

Resource tags were never activated as billing cost allocation dimensions. The stated evidence instead indicates: Disjoint local-account trails leave central auditors with incomplete visibility.

C:

The remote principal has S3 object access but lacks required key-policy and IAM decrypt permission. The stated evidence instead indicates: Disjoint local-account trails leave central auditors with incomplete visibility.

D:

Individual Security Hub instances were not centrally delegated or aggregated. The stated evidence instead indicates: Disjoint local-account trails leave central auditors with incomplete visibility.

Question 221

For the enterprise requirement "A company uses Direct Connect for normal hybrid traffic but needs encrypted emergency connectivity if carrier circuits fail", the team implemented this change: Configure redundant site-to-site VPN tunnels as the tested backup to the Direct Connect path. Which observation should be required before the change is approved?

  1. Traffic crosses the regional peering attachment only for specifically installed and approved prefixes
  2. Consumer instances reach only the approved PrivateLink service while unrelated provider subnets remain unreachable
  3. Tested resized instances meet p95 latency goals while recommended savings are observed
  4. A simulated Direct Connect failure moves approved routes to VPN tunnels and restore reverses route preference

Explanation

Correct Answer

D:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. A tested secondary encrypted tunnel path can carry critical traffic while primary private connectivity is unavailable. The acceptance condition is linked directly to the scenario: A company uses Direct Connect for normal hybrid traffic but needs encrypted emergency connectivity if carrier circuits fail.

Incorrect Answers

A:

Traffic crosses the regional peering attachment only for specifically installed and approved prefixes. However, this does not establish the required outcome: a simulated Direct Connect failure moves approved routes to VPN tunnels and restore reverses route preference.

B:

Consumer instances reach only the approved PrivateLink service while unrelated provider subnets remain unreachable. However, this does not establish the required outcome: a simulated Direct Connect failure moves approved routes to VPN tunnels and restore reverses route preference.

C:

Tested resized instances meet p95 latency goals while recommended savings are observed. However, this does not establish the required outcome: a simulated Direct Connect failure moves approved routes to VPN tunnels and restore reverses route preference.

Question 222

A deployed environment still does not meet the original requirement: A database team purchased oversized io2 EBS performance when measured throughput is far below its actual needs. Which missing control accounts for the continuing issue?

  1. Premium IOPS are maintained without evidence of workload needing them
  2. Health checks use an unrelated always-200 endpoint that does not reflect the service readiness
  3. Workload service calls repeatedly cross paid network boundaries without quantified need
  4. Shared costs are assigned by arbitrary percentage without service consumption evidence

Explanation

Correct Answer

A:

This is the technical design error aligned with the unmet requirement. EBS volume-class selection should follow measured IO and durability requirements. The appropriate correction is: Benchmark throughput and latency, then evaluate a supported gp3 volume where required performance fits. The control should then be tested by verifying that Tested gp3 configuration meets IO SLOs at lower monthly storage and provisioned-performance cost.

Incorrect Answers

B:

Health checks use an unrelated always-200 endpoint that does not reflect the service readiness. The stated evidence instead indicates: Premium IOPS are maintained without evidence of workload needing them.

C:

Workload service calls repeatedly cross paid network boundaries without quantified need. The stated evidence instead indicates: Premium IOPS are maintained without evidence of workload needing them.

D:

Shared costs are assigned by arbitrary percentage without service consumption evidence. The stated evidence instead indicates: Premium IOPS are maintained without evidence of workload needing them.

Question 223

An enterprise architecture team faces this design requirement: Internal mTLS certificates for services must be issued under a private organizational trust root with controlled rotation. What should the solutions architect recommend?

  1. Configure Security Hub delegated administrator and member account aggregation or finding aggregation as supported
  2. Use AWS Private CA to issue private certificates with a managed trust chain and documented renewal
  3. Configure IAM Identity Center with enterprise IdP integration, permission sets and controlled account assignments
  4. Analyze organization-wide RI utilization and coverage using consolidated billing reports

Explanation

Correct Answer

B:

AWS Private CA supports private certificate authorities for internal certificate issuance. The required architecture outcome is: Internal mTLS certificates for services must be issued under a private organizational trust root with controlled rotation. Validate this choice by checking that A client trusts the correct private CA chain and rejects a certificate issued outside that trust.

Incorrect Answers

A:

Individual Security Hub instances were not centrally delegated or aggregated. The specific problem here is that public ACM-issued certificates were wrongly assumed to provide a corporate private CA chain.

C:

Individual IAM users were being created per account instead of using centralized workforce federation. The specific problem here is that public ACM-issued certificates were wrongly assumed to provide a corporate private CA chain.

D:

RI purchases are evaluated only in the purchasing account without considering shared billing treatment. The specific problem here is that public ACM-issued certificates were wrongly assumed to provide a corporate private CA chain.

Question 224

A deployed environment still does not meet the original requirement: A reporting dashboard overloads a relational database primary with read queries but still requires strongly controlled write ownership. Which root cause is most consistent with the observation?

  1. Read-only analytical traffic saturates the production database's single writable instance
  2. Instance-local caches cannot share consistent ephemeral state across horizontally scaled hosts
  3. Region-specific public IPs and DNS routing do not provide the needed global anycast transport optimization
  4. The workload uses only on-demand capacity despite safe restart or checkpoint semantics

Explanation

Correct Answer

A:

This is the technical design error aligned with the unmet requirement. RDS read replicas scale read throughput but are asynchronous relative to the primary. The appropriate correction is: Add supported RDS read replicas and route eventually consistent reporting reads away from the writer. The control should then be tested by verifying that Writer CPU usage decreases while lag-tolerant reporting requests use replica endpoints.

Incorrect Answers

B:

Instance-local caches cannot share consistent ephemeral state across horizontally scaled hosts. The stated evidence instead indicates: Read-only analytical traffic saturates the production database's single writable instance.

C:

Region-specific public IPs and DNS routing do not provide the needed global anycast transport optimization. The stated evidence instead indicates: Read-only analytical traffic saturates the production database's single writable instance.

D:

The workload uses only on-demand capacity despite safe restart or checkpoint semantics. The stated evidence instead indicates: Read-only analytical traffic saturates the production database's single writable instance.

Question 225

A deployed environment still does not meet the original requirement: Regulators require consistent detection and correction of publicly accessible S3 buckets across a multi-account organization. What original architectural gap most directly explains the failure?

  1. Public ACM-issued certificates were wrongly assumed to provide a corporate private CA chain
  2. Per-account one-off inspections do not continuously evaluate drift across accounts
  3. Local identity permissions were incorrectly treated as overriding organizational guardrails
  4. The team relies exclusively on retrospective end-of-month billing statements

Explanation

Correct Answer

B:

This is the technical design error aligned with the unmet requirement. Organization-level Config rules continuously evaluate configuration and can launch controlled remediations. The appropriate correction is: Deploy organization-managed AWS Config rules and targeted auto-remediation through approved Systems Manager Automation. The control should then be tested by verifying that A noncompliant test bucket is flagged and the remediation removes its unauthorized public exposure.

Incorrect Answers

A:

Public ACM-issued certificates were wrongly assumed to provide a corporate private CA chain. The stated evidence instead indicates: Per-account one-off inspections do not continuously evaluate drift across accounts.

C:

Local identity permissions were incorrectly treated as overriding organizational guardrails. The stated evidence instead indicates: Per-account one-off inspections do not continuously evaluate drift across accounts.

D:

The team relies exclusively on retrospective end-of-month billing statements. The stated evidence instead indicates: Per-account one-off inspections do not continuously evaluate drift across accounts.

Question 226

A deployed environment still does not meet the original requirement: Two regional Transit Gateways must exchange approved network prefixes without provisioning a separate VPC-to-VPC peering mesh. What was most likely overlooked in the original design?

  1. The architecture assumes that Transit Gateway peering automatically propagates interregional routes
  2. There is no independently functioning VPN path when private connectivity goes down
  3. On-premises DNS has no forwarding path into the VPC's Route 53 Resolver
  4. Per-account one-off inspections do not continuously evaluate drift across accounts

Explanation

Correct Answer

A:

This is the technical design error aligned with the unmet requirement. Transit Gateway peering requires explicit routing between the regional gateways. The appropriate correction is: Establish a Transit Gateway peering attachment and add the appropriate static routes in both Transit Gateway route tables. The control should then be tested by verifying that Traffic crosses the regional peering attachment only for specifically installed and approved prefixes.

Incorrect Answers

B:

There is no independently functioning VPN path when private connectivity goes down. The stated evidence instead indicates: The architecture assumes that Transit Gateway peering automatically propagates interregional routes.

C:

On-premises DNS has no forwarding path into the VPC's Route 53 Resolver. The stated evidence instead indicates: The architecture assumes that Transit Gateway peering automatically propagates interregional routes.

D:

Per-account one-off inspections do not continuously evaluate drift across accounts. The stated evidence instead indicates: The architecture assumes that Transit Gateway peering automatically propagates interregional routes.

Question 227

For the enterprise requirement "Six VPCs in three accounts need private east-west connectivity without an O(N²) peering mesh", the team implemented this change: Attach the VPCs to one centrally governed Transit Gateway and propagate approved attachment routes. Which outcome is the most meaningful acceptance test?

  1. Consumer instances reach only the approved PrivateLink service while unrelated provider subnets remain unreachable
  2. Backups remain recoverable from the dedicated account even when the application account is disabled
  3. Approved application subnets reach each other through Transit Gateway routes and unauthorized segments remain isolated
  4. A simulated Direct Connect failure moves approved routes to VPN tunnels and restore reverses route preference

Explanation

Correct Answer

C:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. Transit Gateway supplies centralized transitive VPC connectivity when attachment route tables and security policies are configured. The acceptance condition is linked directly to the scenario: Six VPCs in three accounts need private east-west connectivity without an O(N²) peering mesh.

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: approved application subnets reach each other through Transit Gateway routes and unauthorized segments remain isolated.

B:

Backups remain recoverable from the dedicated account even when the application account is disabled. However, this does not establish the required outcome: approved application subnets reach each other through Transit Gateway routes and unauthorized segments remain isolated.

D:

A simulated Direct Connect failure moves approved routes to VPN tunnels and restore reverses route preference. However, this does not establish the required outcome: approved application subnets reach each other through Transit Gateway routes and unauthorized segments remain isolated.

Question 228

For the enterprise requirement "A legacy billing system runs nightly ETL and downstream consumers need near-real-time invoice changes", the team implemented this change: Introduce change data capture and an event stream or bus with replay and idempotent consumers. Which result specifically demonstrates the fix works?

  1. An end-to-end test request shows linked spans and reveals downstream latency without leaking credentials
  2. The proposed target design has documented permitted license use and tracked license utilization
  3. Invoice updates arrive at consumers within the required lag and replay does not duplicate side effects
  4. A fresh environment can be recreated from code with predictable parameters and drift checks

Explanation

Correct Answer

C:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. CDC-based event distribution can modernize delayed batch data propagation. The acceptance condition is linked directly to the scenario: A legacy billing system runs nightly ETL and downstream consumers need near-real-time invoice changes.

Incorrect Answers

A:

An end-to-end test request shows linked spans and reveals downstream latency without leaking credentials. However, this does not establish the required outcome: invoice updates arrive at consumers within the required lag and replay does not duplicate side effects.

B:

The proposed target design has documented permitted license use and tracked license utilization. However, this does not establish the required outcome: invoice updates arrive at consumers within the required lag and replay does not duplicate side effects.

D:

A fresh environment can be recreated from code with predictable parameters and drift checks. However, this does not establish the required outcome: invoice updates arrive at consumers within the required lag and replay does not duplicate side effects.

Question 229

A deployed environment still does not meet the original requirement: Governance wants one AWS Config compliance view from many accounts and Regions. What design flaw is the best match for the reported condition?

  1. Individual accounts use drifting custom schedules that do not match central backup policy
  2. Local Config assessments exist but no aggregation exposes cross-account status
  3. There is no independently functioning VPN path when private connectivity goes down
  4. New accounts are assembled by ad hoc scripts with inconsistent security baselines

Explanation

Correct Answer

B:

This is the technical design error aligned with the unmet requirement. AWS Config aggregators consolidate configuration and compliance data without changing source resources. The appropriate correction is: Configure a Config aggregator with organization or account sources and appropriate delegated read access. The control should then be tested by verifying that Central compliance dashboards include resource findings from configured participating accounts and Regions.

Incorrect Answers

A:

Individual accounts use drifting custom schedules that do not match central backup policy. The stated evidence instead indicates: Local Config assessments exist but no aggregation exposes cross-account status.

C:

There is no independently functioning VPN path when private connectivity goes down. The stated evidence instead indicates: Local Config assessments exist but no aggregation exposes cross-account status.

D:

New accounts are assembled by ad hoc scripts with inconsistent security baselines. The stated evidence instead indicates: Local Config assessments exist but no aggregation exposes cross-account status.

Question 230

An enterprise architecture team faces this design requirement: A legacy data center lacks a trustworthy inventory of server CPU, memory, installed processes and network connections. Which proposed change addresses the stated constraint most directly?

  1. Estimate transfer duration and select online versus physical transfer based on throughput, change rate and cutoff window
  2. Track AWS Transform migration wave and server states, and maintain centrally owned application milestones, blockers and cutover decisions
  3. Introduce change data capture and an event stream or bus with replay and idempotent consumers
  4. Use AWS Transform discovery and assessment, or a supported inventory tool, to measure server characteristics and network dependency data

Explanation

Correct Answer

D:

Application discovery captures real workload characteristics needed for migration planning. The required architecture outcome is: A legacy data center lacks a trustworthy inventory of server CPU, memory, installed processes and network connections. Validate this choice by checking that Captured workload attributes reveal which servers can be rehosted together and which need further assessment.

Incorrect Answers

A:

A simple online copy was selected without calculating network capacity and transfer duration. The specific problem here is that migration estimates are based solely on outdated procurement records rather than measured workload behavior.

B:

Migration tasks are tracked in separate team documents with no common portfolio state. The specific problem here is that migration estimates are based solely on outdated procurement records rather than measured workload behavior.

C:

All consumers wait for a nightly export despite a near-real-time freshness requirement. The specific problem here is that migration estimates are based solely on outdated procurement records rather than measured workload behavior.
