Amazon AWS Certified Solutions Architect - Professional SAP-C02 Practice Test 3

Question 20

An enterprise architecture team faces this design requirement: A personal-health-record system has strict regional data residency and encryption obligations before any cloud transfer. Which option best aligns with the business and technical requirement?

  1. Classify applications through a defined 7 Rs migration assessment with business value, risk and retirement criteria
  2. Classify sensitive datasets and map AWS Regions, key ownership and access controls before selecting migration waves
  3. Assess schema, procedural conversion complexity and application query compatibility using suitable database migration assessment tools
  4. Package services into supported containers and deploy with ECS on Fargate and scalable load balancing

Explanation

Correct Answer

B:

Regulatory and data-classification constraints affect target location and migration scope. The required architecture outcome is: A personal-health-record system has strict regional data residency and encryption obligations before any cloud transfer. Validate this choice by checking that An approved target design demonstrates residency and encryption enforcement before copying production records.

Incorrect Answers

A:

All assets are scheduled for direct rehost even when some are obsolete or unsuitable. The specific problem here is that migration scheduling ignored data classification and jurisdictional control requirements.

C:

Database engine migration was assumed to be a simple homogeneous replication job. The specific problem here is that migration scheduling ignored data classification and jurisdictional control requirements.

D:

Dedicated EC2 servers remain the scaling bottleneck for stateless containerized workloads. The specific problem here is that migration scheduling ignored data classification and jurisdictional control requirements.

Question 21

An enterprise architecture team faces this design requirement: A product catalog on DynamoDB receives many repeated eventually consistent key lookups and requires microsecond cache responses. What design change should the team implement?

  1. Adjust stream capacity mode or shard count and confirm partition key distribution
  2. Use an appropriately designed active-active multi-Region architecture with global routing and compatible data replication
  3. Configure CloudFront caching with appropriate TTL, cache keys and regional origin controls
  4. Introduce DynamoDB DAX for supported cacheable read paths and check data freshness requirements

Explanation

Correct Answer

D:

DAX offers managed in-memory caching for eligible DynamoDB read workloads. The required architecture outcome is: A product catalog on DynamoDB receives many repeated eventually consistent key lookups and requires microsecond cache responses. Validate this choice by checking that The repeated key lookup hits DAX with lower latency while noncacheable paths use the underlying table.

Incorrect Answers

A:

Stream shard limits or skewed partition keys cannot handle incoming record throughput. The specific problem here is that every read request traverses the backing DynamoDB service despite highly reusable cacheable data.

B:

A single active Region was incorrectly advertised as having near-zero recovery time. The specific problem here is that every read request traverses the backing DynamoDB service despite highly reusable cacheable data.

C:

Every static asset fetch goes to a distant origin instead of the edge cache. The specific problem here is that every read request traverses the backing DynamoDB service despite highly reusable cacheable data.

Question 22

An architecture review recommends this solution: Configure the applicable AWS Organizations delegated administrator in a dedicated security account. The motivating situation is: An organization needs a central security team to administer Inspector or GuardDuty for member accounts without using the management account daily. Why is this architecture appropriate for the described workload?

  1. Service-specific delegated administration provides controlled cross-account security operations
  2. Compute Savings Plans apply eligible usage discounts across supported services and configurations
  3. AWS RAM can share supported resources while ownership remains in a central account
  4. An organization trail and protected storage form a centralized account-wide auditing design

Explanation

Correct Answer

A:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Configure the applicable AWS Organizations delegated administrator in a dedicated security account. The expected supporting evidence is: The delegated administrator can manage enrolled member security coverage within its supported scope.

Incorrect Answers

B:

On-demand usage was left wholly uncommitted despite predictable baseline compute consumption. The stated evidence instead indicates: Management-account-only operations were mistaken for necessary daily centralized security administration.

C:

Each application team is provisioning its own disconnected backbone gateway. The stated evidence instead indicates: Management-account-only operations were mistaken for necessary daily centralized security administration.

D:

Local activity trails are not consolidated into the audit security boundary. The stated evidence instead indicates: Management-account-only operations were mistaken for necessary daily centralized security administration.

Question 23

A professional architect is reviewing two independent workstreams. Requirement A: A service needs to replay historical event notifications after a downstream subscriber defect is corrected. Requirement B: Business units need temporary developer access to multiple accounts but not permanent local IAM users. Choose TWO actions that directly address these separate problems.

  1. Enable VPC subnet sharing through AWS RAM for eligible accounts in the same organization
  2. Enable EventBridge event-bus archive and replay for eligible matching events
  3. Place an SQS queue between submission and processing, with appropriately scaled consumers and DLQ policy
  4. Set up IAM Identity Center account assignments with role-scoped permission sets and centralized joiner-leaver management
  5. Apply a targeted Organizations service control policy denying prohibited CloudTrail disablement actions in affected OUs

Explanation

Correct Answers

B:

This action meets the independently stated requirement A: A service needs to replay historical event notifications after a downstream subscriber defect is corrected. EventBridge archives support bounded replay of previously captured events. A direct acceptance check is: The selected time window can be replayed to the target bus without inventing events that were never archived.

D:

This action meets the independently stated requirement B: Business units need temporary developer access to multiple accounts but not permanent local IAM users. Central identity assignments reduce stale credentials and standardize workforce access. A direct acceptance check is: Revoking a staff member's assignment removes their delegated access without per-account user deletion.

Incorrect Answers

A:

This action targets a different technical need: Network administrators must manage a shared subnet centrally while application accounts place their own resources in it. It does not replace either required solution in A or B. VPC sharing separates network ownership from application resource ownership; verify the two stated requirements independently rather than accepting an unrelated change.

C:

This action targets a different technical need: Order processing must survive transient database outages without permanently losing accepted incoming work. It does not replace either required solution in A or B. Durable queues decouple intake availability from downstream processing failures; verify the two stated requirements independently rather than accepting an unrelated change.

E:

This action targets a different technical need: A multi-account organization must prevent member accounts from disabling mandatory CloudTrail trails even when local administrators hold broad IAM policies. It does not replace either required solution in A or B. Service control policies set permission ceilings for member account principals and cannot grant access themselves; verify the two stated requirements independently rather than accepting an unrelated change.

Question 24

A professional architect is reviewing two independent workstreams. Requirement A: On-premises servers must resolve names in a private Route 53 hosted zone without exposing those records publicly. Requirement B: A vendor assumes a role into an AWS account and must be restricted to one project's S3 prefix for that session only. Which TWO architecture changes cover both acceptance criteria?

  1. Activate standardized cost allocation tags and enforce tagging through governance processes
  2. Deploy organization-managed AWS Config rules and targeted auto-remediation through approved Systems Manager Automation
  3. Require tightly scoped role trust and a scoped session policy or condition that limits the assumed-role credentials
  4. Configure redundant site-to-site VPN tunnels as the tested backup to the Direct Connect path
  5. Deploy Route 53 Resolver inbound endpoints and configure corporate conditional DNS forwarding for the private zone

Explanation

Correct Answers

C:

This action meets the independently stated requirement B: A vendor assumes a role into an AWS account and must be restricted to one project's S3 prefix for that session only. Session policies intersect with role permissions and can reduce privileges for one temporary session. A direct acceptance check is: The assumed session can read the approved prefix and is denied a separate confidential prefix.

E:

This action meets the independently stated requirement A: On-premises servers must resolve names in a private Route 53 hosted zone without exposing those records publicly. Inbound Resolver endpoints enable hybrid clients to ask VPC-associated private-zone DNS questions. A direct acceptance check is: Queries from on-premises resolvers return the expected private-zone records through inbound endpoint addresses.

Incorrect Answers

A:

This action targets a different technical need: Finance needs engineering costs apportioned by team using tags rather than guessed from account totals. It does not replace either required solution in A or B. Cost allocation tags must be activated before they appear in billing cost analytics; verify the two stated requirements independently rather than accepting an unrelated change.

B:

This action targets a different technical need: Regulators require consistent detection and correction of publicly accessible S3 buckets across a multi-account organization. It does not replace either required solution in A or B. Organization-level Config rules continuously evaluate configuration and can launch controlled remediations; verify the two stated requirements independently rather than accepting an unrelated change.

D:

This action targets a different technical need: A company uses Direct Connect for normal hybrid traffic but needs encrypted emergency connectivity if carrier circuits fail. It does not replace either required solution in A or B. A tested secondary encrypted tunnel path can carry critical traffic while primary private connectivity is unavailable; verify the two stated requirements independently rather than accepting an unrelated change.

Question 25

An enterprise architecture team faces this design requirement: A producer account encrypts S3 objects under its KMS key and a distinct consumer role must decrypt those objects cross-account. Which action would resolve the problem without adding unrelated capabilities?

  1. Configure an organization trail delivered to a protected central S3 bucket with appropriate key and bucket controls
  2. Update the key policy and consumer IAM permissions for the cross-account principal, alongside S3 access authorization
  3. Use AWS Private CA to issue private certificates with a managed trust chain and documented renewal
  4. Configure redundant site-to-site VPN tunnels as the tested backup to the Direct Connect path

Explanation

Correct Answer

B:

Cross-account KMS use requires authorization from the key-owning account and the requesting principal. The required architecture outcome is: A producer account encrypts S3 objects under its KMS key and a distinct consumer role must decrypt those objects cross-account. Validate this choice by checking that The consumer role reads approved encrypted objects but cannot decrypt other protected datasets.

Incorrect Answers

A:

Disjoint local-account trails leave central auditors with incomplete visibility. The specific problem here is that the remote principal has S3 object access but lacks required key-policy and IAM decrypt permission.

C:

Public ACM-issued certificates were wrongly assumed to provide a corporate private CA chain. The specific problem here is that the remote principal has S3 object access but lacks required key-policy and IAM decrypt permission.

D:

There is no independently functioning VPN path when private connectivity goes down. The specific problem here is that the remote principal has S3 object access but lacks required key-policy and IAM decrypt permission.

Question 26

An enterprise architecture team faces this design requirement: Governance wants one AWS Config compliance view from many accounts and Regions. Which proposed change addresses the stated constraint most directly?

  1. Configure a Config aggregator with organization or account sources and appropriate delegated read access
  2. Require tightly scoped role trust and a scoped session policy or condition that limits the assumed-role credentials
  3. Publish permitted events across account boundaries to a central EventBridge event bus with explicit resource policy
  4. Use distinct AWS Organizations organizational units and apply targeted service control policies per OU

Explanation

Correct Answer

A:

AWS Config aggregators consolidate configuration and compliance data without changing source resources. The required architecture outcome is: Governance wants one AWS Config compliance view from many accounts and Regions. Validate this choice by checking that Central compliance dashboards include resource findings from configured participating accounts and Regions.

Incorrect Answers

B:

An overly broad assumed-role session is not constrained to the vendor's assigned resources. The specific problem here is that local Config assessments exist but no aggregation exposes cross-account status.

C:

Events remain confined to local account buses because cross-account bus authorization is absent. The specific problem here is that local Config assessments exist but no aggregation exposes cross-account status.

D:

All accounts share one indiscriminate service-control policy despite different risk profiles. The specific problem here is that local Config assessments exist but no aggregation exposes cross-account status.

Question 27

A deployed environment still does not meet the original requirement: The security team manages GuardDuty separately in 50 accounts and misses newly created member accounts. What design flaw is the best match for the reported condition?

  1. Snapshot creation is mistaken for proof the application can actually be restored
  2. Threat detection remains inconsistently deployed across member accounts and Regions
  3. Teams confuse key material rotation with replacing the KMS key ID and losing access to old data
  4. One overbroad bucket-level policy grants both teams access to all data

Explanation

Correct Answer

B:

This is the technical design error aligned with the unmet requirement. Central GuardDuty administration supports ongoing multi-account detection enrollment. The appropriate correction is: Configure organization-wide GuardDuty administration with supported automatic enrollment and region strategy. The control should then be tested by verifying that Existing and new participating accounts report eligible findings to the delegated administrator.

Incorrect Answers

A:

Snapshot creation is mistaken for proof the application can actually be restored. The stated evidence instead indicates: Threat detection remains inconsistently deployed across member accounts and Regions.

C:

Teams confuse key material rotation with replacing the KMS key ID and losing access to old data. The stated evidence instead indicates: Threat detection remains inconsistently deployed across member accounts and Regions.

D:

One overbroad bucket-level policy grants both teams access to all data. The stated evidence instead indicates: Threat detection remains inconsistently deployed across member accounts and Regions.

Question 28

An enterprise architecture team faces this design requirement: A worldwide public application targets near-zero regional failover time and already tolerates multi-Region data conflict semantics. Which action would resolve the problem without adding unrelated capabilities?

  1. Add an S3 gateway VPC endpoint and route supported S3 traffic privately rather than through NAT
  2. Use an appropriately designed active-active multi-Region architecture with global routing and compatible data replication
  3. Configure a suitable RDS cross-Region read replica where supported and rehearse replica promotion and endpoint changes
  4. Configure S3 replication rules with correct versioning and KMS permissions for destination encrypted objects

Explanation

Correct Answer

B:

Active-active architectures provide immediate regional capacity but require safe multi-Region data behavior. The required architecture outcome is: A worldwide public application targets near-zero regional failover time and already tolerates multi-Region data conflict semantics. Validate this choice by checking that Failure of one Region does not interrupt healthy remaining regional capacity under synthetic load.

Incorrect Answers

A:

S3 calls egress through NAT because no supported endpoint route was configured. The specific problem here is that a single active Region was incorrectly advertised as having near-zero recovery time.

C:

A standard read replica is assumed to be a synchronous multi-Region failover mechanism without promotion. The specific problem here is that a single active Region was incorrectly advertised as having near-zero recovery time.

D:

The destination bucket is present but replication cannot use the destination KMS key. The specific problem here is that a single active Region was incorrectly advertised as having near-zero recovery time.

Question 29

An enterprise architecture team faces this design requirement: An application runs a small cron job on a permanently running EC2 server, which spends most time idle. What design change should the team implement?

  1. Use staged schema compatibility, full-load plus CDC migration and controlled dual-environment cutover tests
  2. Apply the strangler pattern, routing one well-defined capability at a time to a tested new service
  3. Move the schedule to EventBridge Scheduler with an appropriately scoped Lambda or supported task target
  4. Evaluate Amazon MQ with an appropriate compatible engine and migrate broker connections in stages

Explanation

Correct Answer

C:

Managed scheduling can invoke short-lived compute without operating a permanent cron host. The required architecture outcome is: An application runs a small cron job on a permanently running EC2 server, which spends most time idle. Validate this choice by checking that The job executes at its configured schedule while no dedicated idle EC2 host is required.

Incorrect Answers

A:

A one-time export leaves days of writes uncopied before final deployment. The specific problem here is that the only purpose of a 24/7 server is occasional timer-based work.

B:

An all-at-once replacement has unacceptable outage and rollback risk. The specific problem here is that the only purpose of a 24/7 server is occasional timer-based work.

D:

Developers assume SQS has identical JMS or broker feature semantics to the source stack. The specific problem here is that the only purpose of a 24/7 server is occasional timer-based work.

Question 30

An architecture review recommends this solution: Configure Global Accelerator listeners and healthy regional ALB or NLB endpoints. The motivating situation is: A global TCP service wants static public entry addresses and traffic steering over the AWS global network for lowest path latency. What principle supports the selected implementation?

  1. CloudFront edge caching reduces origin fetches for cacheable content
  2. SQS dead-letter queues preserve failed messages for separate inspection and remediation
  3. Global Accelerator accelerates supported TCP/UDP applications without serving as an HTTP content cache
  4. A shared in-memory cache reduces backend read pressure when expiry and failure behavior are designed

Explanation

Correct Answer

C:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Configure Global Accelerator listeners and healthy regional ALB or NLB endpoints. The expected supporting evidence is: Clients use accelerator anycast addresses and connect to the healthy regional endpoint with improved path latency.

Incorrect Answers

A:

Every static asset fetch goes to a distant origin instead of the edge cache. The stated evidence instead indicates: Region-specific public IPs and DNS routing do not provide the needed global anycast transport optimization.

B:

Repeated retries of one failed message prevent useful error isolation and redrive workflow. The stated evidence instead indicates: Region-specific public IPs and DNS routing do not provide the needed global anycast transport optimization.

D:

Instance-local caches cannot share consistent ephemeral state across horizontally scaled hosts. The stated evidence instead indicates: Region-specific public IPs and DNS routing do not provide the needed global anycast transport optimization.
