Explanation
Correct Answer
B:For finding 1: Multiple AWS Regions let a business place workloads nearer users without constructing its own international facilities. For finding 2: Cloud infrastructure can shorten the time from an approved request to usable computing capacity. Both actions are required.
Incorrect Answers
A:For finding 2: Cloud infrastructure can shorten the time from an approved request to usable computing capacity. That action addresses a different situation: A government program requires citizen records to remain in an approved geography even though customers access its portal globally.
C:For finding 1: Multiple AWS Regions let a business place workloads nearer users without constructing its own international facilities. That action addresses a different situation: A photo-sharing site has visitors worldwide and repeated downloads of the same static images from one distant origin.
D:The actions are reversed. The correct order is (1) Deploy the application in an appropriate AWS Region closer to those customers after checking residency and service availability. (2) Provision appropriately sized AWS resources on demand instead of waiting for company-owned servers to be purchased.
Question 311
A heterogeneous database migration needs schema and code conversion as well as moving the stored data between platforms. Which response best addresses the situation?
- Evaluate AWS Schema Conversion Tool alongside a supported data migration strategy.
- Evaluate AWS Database Migration Service for a supported migration and change-replication process.
- Evaluate Amazon ElastiCache as a cache layer with an appropriate consistency and expiration policy.
- Evaluate Amazon DynamoDB for a managed key-value or document database access pattern.
Explanation
Correct Answer
A:Schema conversion and data transport are separate concerns when database platforms differ.
Incorrect Answers
B:Schema conversion and data transport are separate concerns when database platforms differ. That alternative applies to a different situation: A company plans to migrate a production database into AWS while keeping source changes flowing through a staged cutover.
C:Schema conversion and data transport are separate concerns when database platforms differ. That alternative applies to a different situation: A read-heavy application repeatedly queries the same session data and would benefit from low-latency in-memory access.
D:Schema conversion and data transport are separate concerns when database platforms differ. That alternative applies to a different situation: A mobile game needs predictable key-value access to millions of player profiles without requiring relational joins.
Question 312
An AWS planning meeting highlights two independent requirements. Finding 1: A security reviewer grants a support engineer temporary diagnostic access, but the permission remains indefinitely after the incident closes. Finding 2: A team believes that encrypting an IAM access key file means the principal's permissions can safely include every AWS action. Which two-part response addresses both findings in order?
- (1) Limit the IAM principal's permissions independently of how its credentials are stored. (2) Time-bound or remove the elevated access after its approved purpose ends and retain an access review record.
- (1) Time-bound or remove the elevated access after its approved purpose ends and retain an access review record. (2) Store and rotate the token through an approved AWS secret-management workflow with limited retrieval permissions.
- (1) Time-bound or remove the elevated access after its approved purpose ends and retain an access review record. (2) Limit the IAM principal's permissions independently of how its credentials are stored.
- (1) Replace the distributed key with a suitable role-based short-lived credential mechanism and rotate exposed material. (2) Limit the IAM principal's permissions independently of how its credentials are stored.
Explanation
Correct Answer
C:For finding 1: Privilege should not remain standing once its business justification has expired. For finding 2: Credential confidentiality does not replace least-privilege authorization. Both actions are required.
Incorrect Answers
A:The actions are reversed. The correct order is (1) Time-bound or remove the elevated access after its approved purpose ends and retain an access review record. (2) Limit the IAM principal's permissions independently of how its credentials are stored.
B:For finding 2: Credential confidentiality does not replace least-privilege authorization. That action addresses a different situation: A service must retrieve a third-party API token that changes monthly, but operators currently redeploy the application to update the secret.
D:For finding 1: Privilege should not remain standing once its business justification has expired. That action addresses a different situation: An automation script uses a long-lived IAM access key that has been copied into several unencrypted workstation files.
Question 313
A team evaluates a new database service by its cheapest hourly rate alone, ignoring operational effort and service constraints. What should the team do?
- Review the selected service's customer-controlled identity and data settings under the shared responsibility model.
- Apply the Performance Efficiency pillar to select suitable services and use measured elastic scaling where appropriate.
- Apply the Security pillar by limiting permissions to each workload's approved functions and protecting credentials.
- Compare performance, reliability, security, and costs together against the documented business requirement.
Explanation
Correct Answer
D:Well-Architected decisions require balancing trade-offs instead of optimizing one metric in isolation.
Incorrect Answers
A:Well-Architected decisions require balancing trade-offs instead of optimizing one metric in isolation. That alternative applies to a different situation: An application is moved to a managed platform, but the security team assumes the service provider automatically grants only appropriate user access.
B:Well-Architected decisions require balancing trade-offs instead of optimizing one metric in isolation. That alternative applies to a different situation: A public API becomes slow because one server processes all requests even though demand varies by time of day.
C:Well-Architected decisions require balancing trade-offs instead of optimizing one metric in isolation. That alternative applies to a different situation: A development account gives all application workers administrator privileges because that is easier than defining their roles.
Question 314

D:The actions are reversed. The correct order is (1) Evaluate Amazon Kinesis for an appropriate streaming data capture or processing use case. (2) Evaluate AWS Glue for supported data integration, catalog, and ETL workflows.
Question 315
A cloud readiness review raises three separate requirements. Finding 1: A company copies sensitive logs into an S3 bucket with broad access and says AWS's physical safeguards make its data exposure harmless. Finding 2: A production EC2 team disables host logging and antivirus because AWS already monitors the physical machines. Finding 3: An enterprise must choose between a self-managed service on EC2 and a managed service but wants to minimize its OS patching responsibilities. Which complete response addresses all three findings in order?
- (1) Restrict bucket access and apply appropriate encryption and data lifecycle policies before using the bucket for sensitive logs. (2) Remove and rotate the exposed credential and use short-lived role credentials or a suitable secret-management service. (3) Prefer an eligible managed service after confirming the service features and remaining customer security obligations.

Explanation
Correct Answer
C:For finding 1: Physical infrastructure security cannot compensate for an overly permissive customer-controlled data policy. For finding 2: Provider infrastructure security does not inspect every process or application inside customer-managed servers. For finding 3: Higher-level managed services can reduce the set of infrastructure components a customer administers. All three decisions are needed.
Incorrect Answers
A:For finding 2: Provider infrastructure security does not inspect every process or application inside customer-managed servers. That action addresses a different situation: A developer puts a long-lived access key in a source repository and assumes AWS automatically prevents public discovery of the value.
B:For finding 3: Higher-level managed services can reduce the set of infrastructure components a customer administers. That action addresses a different situation: A developer puts a long-lived access key in a source repository and assumes AWS automatically prevents public discovery of the value.

Question 316
Two cloud decisions must be made in the stated order. Finding 1: A company spends heavily on owned servers before projects start and wants a model with more consumption-linked spending. Finding 2: An internal platform buys enough storage for predicted five-year growth and pays for all of it before any data is stored. Which two-part response addresses both findings in order?
- (1) Compare total cost of ownership using facility, operations, staffing, and depreciation costs as well as infrastructure pricing. (2) Compare elastic storage consumption with the carrying cost of unused pre-purchased capacity.
- (1) Compare elastic storage consumption with the carrying cost of unused pre-purchased capacity. (2) Compare AWS variable usage charges with the capital and fixed operating costs of owned infrastructure.
- (1) Compare AWS variable usage charges with the capital and fixed operating costs of owned infrastructure. (2) Compare elastic storage consumption with the carrying cost of unused pre-purchased capacity.
- (1) Compare AWS variable usage charges with the capital and fixed operating costs of owned infrastructure. (2) Track actual utilization and configure cost controls because unused or oversized cloud resources still create charges.
Explanation
Correct Answer
C:For finding 1: On-demand cloud resources can move some infrastructure spending from upfront commitments to actual consumption. For finding 2: Consumption-based storage can avoid buying large amounts of idle capacity years in advance. Both actions are required.
Incorrect Answers
A:For finding 1: On-demand cloud resources can move some infrastructure spending from upfront commitments to actual consumption. That action addresses a different situation: A finance analyst compares cloud compute price with hardware purchase price but ignores power, cooling, physical space, and maintenance.
B:The actions are reversed. The correct order is (1) Compare AWS variable usage charges with the capital and fixed operating costs of owned infrastructure. (2) Compare elastic storage consumption with the carrying cost of unused pre-purchased capacity.
D:For finding 2: Consumption-based storage can avoid buying large amounts of idle capacity years in advance. That action addresses a different situation: A product team assumes that using cloud services guarantees an always lower invoice without management or governance.
Question 317

- (1) Validate the actual open findings and remediation evidence instead of treating a dashboard summary as proof of universal safety. (2) Use Amazon Inspector for automated vulnerability assessment of eligible compute workloads.
Explanation
Correct Answer
C:For finding 1: Inspector focuses on exposure and vulnerability findings rather than consolidating unrelated account billing data. For finding 2: Security dashboards summarize evidence but do not themselves prove all identified risks were fixed. Both actions are required.
Incorrect Answers
A:For finding 2: Security dashboards summarize evidence but do not themselves prove all identified risks were fixed. That action addresses a different situation: A large organization has security findings from multiple AWS services and wants one prioritized view across accounts.
B:For finding 1: Inspector focuses on exposure and vulnerability findings rather than consolidating unrelated account billing data. That action addresses a different situation: A security team wants to identify suspicious account API behavior and anomalous network activity without building its own threat intelligence detector.
D:The actions are reversed. The correct order is (1) Use Amazon Inspector for automated vulnerability assessment of eligible compute workloads. (2) Validate the actual open findings and remediation evidence instead of treating a dashboard summary as proof of universal safety.
Question 319
A team identifies three independent cloud planning needs. Finding 1: A workload is sized for 24-hour peak traffic even though metrics show the peak lasts only thirty minutes daily. Finding 2: A company wants to assess the environmental impact of its IT design but compares suppliers only by data center building age. Finding 3: A finance department assumes the lowest monthly AWS invoice always represents the best architecture regardless of availability or security risk. Which complete response addresses all three findings in order?
- (1) Apply the Cost Optimization pillar to review demand and rightsize or scale the resources against measured requirements. (2) Use the Sustainability pillar to examine resource efficiency and the environmental effects of workload choices. (3) Reduce unnecessary computation through an appropriate incremental workflow and measure its resource consumption.
- (1) Apply the Cost Optimization pillar to review demand and rightsize or scale the resources against measured requirements. (2) Reduce unnecessary computation through an appropriate incremental workflow and measure its resource consumption.
