Question 270

For the enterprise requirement "External trading partners depend on SFTP interfaces, but the receiving application will store files in S3", the team implemented this change: Use AWS Transfer Family with a supported SFTP endpoint and appropriate identity and S3 permissions. Which evidence confirms the intended behavior under test?

  1. Eligible file changes are transferred and verified by a scheduled DataSync task
  2. Replicated servers boot in AWS test VPCs with verified application functionality before cutover
  3. Vendor-certified testing proves that the appliance runs on the selected target or requires retain/replace decision
  4. Partners connect over SFTP and transferred objects appear in assigned bucket prefixes

Explanation

Correct Answer

D:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. AWS Transfer Family exposes managed file-transfer protocols to supported AWS storage. The acceptance condition is linked directly to the scenario: External trading partners depend on SFTP interfaces, but the receiving application will store files in S3.

Incorrect Answers

A:

Eligible file changes are transferred and verified by a scheduled DataSync task. However, this does not establish the required outcome: partners connect over SFTP and transferred objects appear in assigned bucket prefixes.

B:

Replicated servers boot in AWS test VPCs with verified application functionality before cutover. However, this does not establish the required outcome: partners connect over SFTP and transferred objects appear in assigned bucket prefixes.

C:

Vendor-certified testing proves that the appliance runs on the selected target or requires retain/replace decision. However, this does not establish the required outcome: partners connect over SFTP and transferred objects appear in assigned bucket prefixes.

Question 271

A professional architect is reviewing two independent workstreams. Requirement A: The security team manages GuardDuty separately in 50 accounts and misses newly created member accounts. Requirement B: A customer-facing Lambda API has unacceptable first-request latency after inactive periods despite low average invocation cost. Choose TWO actions that directly address these separate problems.

  1. Enable AWS WAF logging to an appropriate destination with sensitive-data handling and analyze matched rules
  2. Select an appropriate EBS gp3 volume with independently provisioned performance settings and test application throughput
  3. Configure organization-wide GuardDuty administration with supported automatic enrollment and region strategy
  4. Configure the supported subscription delivery policy, retries and dead-letter queue where applicable
  5. Configure provisioned concurrency for selected published function aliases with suitable demand planning

Explanation

Correct Answers

C:

This action meets the independently stated requirement A: The security team manages GuardDuty separately in 50 accounts and misses newly created member accounts. Central GuardDuty administration supports ongoing multi-account detection enrollment. A direct acceptance check is: Existing and new participating accounts report eligible findings to the delegated administrator.

E:

This action meets the independently stated requirement B: A customer-facing Lambda API has unacceptable first-request latency after inactive periods despite low average invocation cost. Lambda provisioned concurrency keeps selected execution environments initialized to reduce startup latency. A direct acceptance check is: Cold-start spikes fall for provisioned requests and concurrency utilization stays within budget.

Incorrect Answers

A:

This action targets a different technical need: Attackers continuously probe application URLs and security needs request-level evidence for rule tuning. It does not replace either required solution in A or B. WAF logs provide request and rule evaluation evidence for security tuning; verify the two stated requirements independently rather than accepting an unrelated change.

B:

This action targets a different technical need: An EC2 application needs sustained random IOPS independent of EBS volume storage-size growth. It does not replace either required solution in A or B. gp3 separates baseline volume storage size from configurable IOPS and throughput within limits; verify the two stated requirements independently rather than accepting an unrelated change.

D:

This action targets a different technical need: An SNS topic invokes an asynchronous HTTP subscriber with intermittent failures and business needs controlled redelivery. It does not replace either required solution in A or B. SNS subscriber reliability relies on delivery retries and appropriately configured dead-letter destinations; verify the two stated requirements independently rather than accepting an unrelated change.

Question 272

An enterprise architecture team faces this design requirement: Production maintenance requires an explicit approval and tracked change record before automation updates EC2 systems. Which option best aligns with the business and technical requirement?

  1. Run CloudFormation drift detection with planned change sets and reconcile unintended differences
  2. Gate a least-privilege Systems Manager Automation runbook with an aws:approve step and retain change approval and execution records
  3. Define service level indicators and targets in CloudWatch dashboards and alarms grounded in request success and p95 latency
  4. Enable AWS WAF logging to an appropriate destination with sensitive-data handling and analyze matched rules

Explanation

Correct Answer

B:

Controlled automation separates approval from execution and preserves traceability. The required architecture outcome is: Production maintenance requires an explicit approval and tracked change record before automation updates EC2 systems. Validate this choice by checking that Unauthorized execution is blocked and approved changes have associated audit evidence.

Incorrect Answers

A:

Console edits accumulate because no one compares deployed state with infrastructure definitions. The specific problem here is that administrators run sensitive maintenance scripts with no enforced approval or trail.

C:

Engineers measure host utilization but not the outcomes experienced by users. The specific problem here is that administrators run sensitive maintenance scripts with no enforced approval or trail.

D:

WAF rules are deployed without visibility into which requests they affect. The specific problem here is that administrators run sensitive maintenance scripts with no enforced approval or trail.

Question 273

An architecture review recommends this solution: Define API Gateway throttling limits and usage or monitoring controls that match allowed request rates. The motivating situation is: A shared API must protect downstream capacity during a request spike without losing monitoring of throttled clients. Which architectural reasoning is most accurate for the choice?

  1. S3 Intelligent-Tiering can move eligible objects among access tiers based on access frequency
  2. EventBridge event archives retain matching historical events for later replay
  3. Step Functions supports explicit state-level retry and error handling but side effects still require idempotency
  4. API Gateway throttle controls bound request rates but callers should handle 429 responses

Explanation

Correct Answer

D:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Define API Gateway throttling limits and usage or monitoring controls that match allowed request rates. The expected supporting evidence is: Excess requests return expected throttling responses while permitted traffic continues under peak simulation.

Incorrect Answers

A:

Fixed hot storage is retained for every object because teams cannot forecast access patterns. The stated evidence instead indicates: Unbounded request bursts overload backends because no gateway rate protection is configured.

B:

No event archive exists to replay notifications that failed during downstream processing. The stated evidence instead indicates: Unbounded request bursts overload backends because no gateway rate protection is configured.

C:

Imperative glue retries all upstream steps and creates duplicate side effects. The stated evidence instead indicates: Unbounded request bursts overload backends because no gateway rate protection is configured.

Question 274

A professional architect is reviewing two independent workstreams. Requirement A: An AWS Enterprise Support research customer needs to migrate tens of terabytes from a remote site with unreliable network links and can bring storage to a nearby AWS transfer facility. Requirement B: A platform team requires Kubernetes APIs, admission policies and custom controllers while moving a container platform to AWS. Select TWO independent changes that meet the named requirements.

  1. Reserve an AWS Data Transfer Terminal session and bring compatible encrypted storage to upload through its high-bandwidth AWS connection
  2. Assess license portability, dedicated-host requirements and AWS License Manager before choosing targets
  3. Evaluate AWS Storage Gateway file or volume gateway mode against existing file protocol and caching requirements
  4. Use AWS DataSync agents and tasks with scheduling and integrity validation
  5. Deploy a supported EKS architecture with managed control plane and appropriate node or Fargate capacity

Explanation

Correct Answers

A:

This action meets the independently stated requirement A: An AWS Enterprise Support research customer needs to migrate tens of terabytes from a remote site with unreliable network links and can bring storage to a nearby AWS transfer facility. AWS Data Transfer Terminal allows eligible Enterprise Support customers to bring storage to an AWS transfer site; AWS Snowball Edge is no longer available to new customers. A direct acceptance check is: The Enterprise Support team uploads the approved data during its reserved session and matches end-to-end source and destination checksums.

E:

This action meets the independently stated requirement B: A platform team requires Kubernetes APIs, admission policies and custom controllers while moving a container platform to AWS. EKS provides a managed Kubernetes control plane for teams using Kubernetes-native tooling. A direct acceptance check is: Kubernetes manifests and controllers operate within approved permissions and the control plane is managed.

Incorrect Answers

B:

This action targets a different technical need: A Windows estate contains expensive licensed products whose licensing rights differ between shared tenancy and dedicated hosts. It does not replace either required solution in A or B. License entitlements must be assessed before migration architecture and instance selection; verify the two stated requirements independently rather than accepting an unrelated change.

C:

This action targets a different technical need: Branch offices retain file shares locally but need backup and tiered cloud-backed storage without replacing every client. It does not replace either required solution in A or B. Storage Gateway helps bridge supported on-premises storage protocols to AWS-backed storage; verify the two stated requirements independently rather than accepting an unrelated change.

D:

This action targets a different technical need: A company must perform recurring secure file synchronization from on-premises NAS into Amazon S3 with minimal custom scripting. It does not replace either required solution in A or B. AWS DataSync automates supported file and object movement with verification features; verify the two stated requirements independently rather than accepting an unrelated change.

Question 275

An enterprise architecture team faces this design requirement: A central security team needs automated detections for unusual cross-account API activity and suspected credential misuse. What should the solutions architect recommend?

  1. Move the secret to AWS Secrets Manager and adopt controlled retrieval and rotation integration
  2. Enable GuardDuty organization-wide with designated administrator and configured regional coverage
  3. Update the KMS key policy or grants alongside the principal's IAM permissions as required
  4. Enable and configure supported RDS storage autoscaling limits and monitor growth patterns

Explanation

Correct Answer

B:

GuardDuty consumes AWS data sources to identify suspicious behavior and report findings. The required architecture outcome is: A central security team needs automated detections for unusual cross-account API activity and suspected credential misuse. Validate this choice by checking that A seeded supported suspicious event generates a finding and the delegated administrator can triage it.

Incorrect Answers

A:

A static password in deployment parameters cannot be centrally rotated safely. The specific problem here is that raw CloudTrail logs were collected but no managed threat-detection findings were enabled.

C:

IAM principal permission was mistaken for sufficient access despite a restrictive KMS key policy. The specific problem here is that raw CloudTrail logs were collected but no managed threat-detection findings were enabled.

D:

Storage capacity was fixed without safe growth management under variable data requirements. The specific problem here is that raw CloudTrail logs were collected but no managed threat-detection findings were enabled.

Question 276

For the enterprise requirement "Compliance requires protected organization-wide API activity logs to flow into a centralized security account with controlled deletion", the team implemented this change: Configure an organization trail delivered to a protected central S3 bucket with appropriate key and bucket controls. Which result specifically demonstrates the fix works?

  1. Employees sign in using enterprise identities and receive only the mapped roles in assigned accounts
  2. The consumer role reads approved encrypted objects but cannot decrypt other protected datasets
  3. Every enrolled account produces expected trail events in the security account and workloads cannot delete retained logs
  4. Eligible compute charges reflect the planned commitment discount and remaining coverage is visible

Explanation

Correct Answer

C:

This measures the behavior required by the specific solution, rather than simply checking that it was configured. AWS Organizations trails centralize multi-account CloudTrail logging when storage access is secured. The acceptance condition is linked directly to the scenario: Compliance requires protected organization-wide API activity logs to flow into a centralized security account with controlled deletion.

Incorrect Answers

A:

Employees sign in using enterprise identities and receive only the mapped roles in assigned accounts. However, this does not establish the required outcome: every enrolled account produces expected trail events in the security account and workloads cannot delete retained logs.

B:

The consumer role reads approved encrypted objects but cannot decrypt other protected datasets. However, this does not establish the required outcome: every enrolled account produces expected trail events in the security account and workloads cannot delete retained logs.

D:

Eligible compute charges reflect the planned commitment discount and remaining coverage is visible. However, this does not establish the required outcome: every enrolled account produces expected trail events in the security account and workloads cannot delete retained logs.

Question 277

An architecture review recommends this solution: Use Route 53 failover records with health checks and independently deployed regional stacks. The motivating situation is: A global web application must fail over to a secondary Region if the primary public endpoint becomes unhealthy. Which architectural reasoning is most accurate for the choice?

  1. Route 53 health-check failover can redirect future DNS resolutions between operational regional endpoints
  2. Stateful network inspection requires symmetric paths through the selected inspection appliance
  3. Cross-Region Replication asynchronously copies eligible objects between configured buckets
  4. EventBridge archives support bounded replay of previously captured events

Explanation

Correct Answer

A:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Use Route 53 failover records with health checks and independently deployed regional stacks. The expected supporting evidence is: A synthetic endpoint failure directs new DNS resolutions to the secondary healthy stack within the planned TTL behavior.

Incorrect Answers

B:

The inspection design allows forward and return packets to use different stateful inspection appliances. The stated evidence instead indicates: The backup Region exists but DNS routing never changes after primary endpoint failure.

C:

Only source-region S3 versioning is enabled, but no replication rule or role exists. The stated evidence instead indicates: The backup Region exists but DNS routing never changes after primary endpoint failure.

D:

No archive or retention mechanism was configured before the subscriber outage. The stated evidence instead indicates: The backup Region exists but DNS routing never changes after primary endpoint failure.

Question 278

An architecture review recommends this solution: Share the eligible Transit Gateway using AWS Resource Access Manager and explicit attachment routing permissions. The motivating situation is: A central networking account must share an existing Transit Gateway with application accounts without duplicating it. Which statement explains why the recommendation solves the specific problem?

  1. AWS RAM can share supported resources while ownership remains in a central account
  2. Organizational units help assign governance boundaries to related member accounts
  3. Central identity assignments reduce stale credentials and standardize workforce access
  4. S3 Storage Lens supports visibility into storage activity and efficiency metrics

Explanation

Correct Answer

A:

This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Share the eligible Transit Gateway using AWS Resource Access Manager and explicit attachment routing permissions. The expected supporting evidence is: Approved application accounts can create authorized attachments to the centrally owned gateway.

Incorrect Answers

B:

All accounts share one indiscriminate service-control policy despite different risk profiles. The stated evidence instead indicates: Each application team is provisioning its own disconnected backbone gateway.

C:

Each business unit manually maintains duplicative IAM users in workload accounts. The stated evidence instead indicates: Each application team is provisioning its own disconnected backbone gateway.

D:

Teams have only aggregate bills and cannot locate the source of inefficient storage usage. The stated evidence instead indicates: Each application team is provisioning its own disconnected backbone gateway.

Question 279

A deployed environment still does not meet the original requirement: A Route 53 failover policy must move users between two independent public endpoints when the primary application fails. What was most likely overlooked in the original design?

  1. Every component must be rebuilt from scratch after failure, despite a tighter RTO
  2. Records use ordinary simple routing without failover health awareness
  3. A single active Region was incorrectly advertised as having near-zero recovery time
  4. The disaster-recovery Region has no local image copy and the deployment assumes remote registry availability

Explanation

Correct Answer

B:

This is the technical design error aligned with the unmet requirement. DNS health-based failover changes record responses, but clients may cache prior results. The appropriate correction is: Configure Route 53 health checks with primary and secondary failover records and tested TTL behavior. The control should then be tested by verifying that A primary health-check failure leads subsequent name resolutions toward the healthy backup Region.

Incorrect Answers

A:

Every component must be rebuilt from scratch after failure, despite a tighter RTO. The stated evidence instead indicates: Records use ordinary simple routing without failover health awareness.

C:

A single active Region was incorrectly advertised as having near-zero recovery time. The stated evidence instead indicates: Records use ordinary simple routing without failover health awareness.

D:

The disaster-recovery Region has no local image copy and the deployment assumes remote registry availability. The stated evidence instead indicates: Records use ordinary simple routing without failover health awareness.

Question 280

A professional architect is reviewing two independent workstreams. Requirement A: Two regional Transit Gateways must exchange approved network prefixes without provisioning a separate VPC-to-VPC peering mesh. Requirement B: Compliance requires protected organization-wide API activity logs to flow into a centralized security account with controlled deletion. Choose TWO remedies that meet A and B respectively.

  1. Create an AWS Budget with defined threshold notification recipients and appropriate budget filters
  2. Establish a Transit Gateway peering attachment and add the appropriate static routes in both Transit Gateway route tables
  3. Configure an organization trail delivered to a protected central S3 bucket with appropriate key and bucket controls
  4. Configure redundant site-to-site VPN tunnels as the tested backup to the Direct Connect path
  5. Require tightly scoped role trust and a scoped session policy or condition that limits the assumed-role credentials

Explanation

Correct Answers

B:

This action meets the independently stated requirement A: Two regional Transit Gateways must exchange approved network prefixes without provisioning a separate VPC-to-VPC peering mesh. Transit Gateway peering requires explicit routing between the regional gateways. A direct acceptance check is: Traffic crosses the regional peering attachment only for specifically installed and approved prefixes.

C:

This action meets the independently stated requirement B: Compliance requires protected organization-wide API activity logs to flow into a centralized security account with controlled deletion. AWS Organizations trails centralize multi-account CloudTrail logging when storage access is secured. A direct acceptance check is: Every enrolled account produces expected trail events in the security account and workloads cannot delete retained logs.

Incorrect Answers

A:

This action targets a different technical need: A department must be notified promptly when monthly spending exceeds its threshold. It does not replace either required solution in A or B. AWS Budgets supports spend targets and notifications on actual or forecasted cost; 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.

E:

This action targets a different technical need: A vendor assumes a role into an AWS account and must be restricted to one project's S3 prefix for that session only. It does not replace either required solution in A or B. Session policies intersect with role permissions and can reduce privileges for one temporary session; verify the two stated requirements independently rather than accepting an unrelated change.
