Sample Questions

Question #875 / 1019

A company hosts a data processing application on Amazon EC2 instances within a private subnet. The application requires secure access to Amazon S3 buckets for input and output data. Compliance policies mandate that all data transfers must occur without traversing the public internet.

What should a solutions architect implement to fulfill these requirements in the MOST cost-efficient manner?

A

Configure a NAT gateway to facilitate S3 bucket access.

B

Use AWS Storage Gateway to establish a connection to the S3 buckets.

C

Implement an S3 interface endpoint for accessing the S3 buckets.

D

Create an S3 gateway endpoint to enable access to the S3 buckets.

Question #643 / 1019

A company operates several mobile applications for its different services. Each application generates tens of gigabytes of usage logs daily. A solutions architect must design a scalable solution to enable the company's data analysts to perform ad-hoc analysis of usage trends across all applications. This analysis occurs on a weekly basis over several months and must support standard SQL queries.

Which solution meets these requirements MOST cost-effectively?

A

Store the logs in Amazon S3. Use Amazon Athena for analysis.

B

Store the logs in Amazon RDS. Use a database client for analysis.

C

Store the logs in Amazon OpenSearch Service. Use OpenSearch for analysis.

D

Store the logs in an Amazon EMR cluster. Use a supported SQL framework for analysis.

Sample Questions

Question #297 / 529

A company operates a global web application using Amazon CloudFront, but users report increasing latency. The operations team observes a declining cache hit ratio and identifies that the application generates varying HTTP headers (e.g., mixed-case "User-Agent" and "user-agent") for the same content, causing redundant cache entries. How should the solutions architect optimize caching efficiency?

A

Implement a Lambda@Edge function to normalize header keys to lowercase and remove unnecessary headers. Configure it using the CloudFront viewer request trigger.

B

Modify the CloudFront distribution to disable header-based caching entirely.

C

Deploy an Amazon API Gateway in front of the origin to standardize headers before reaching CloudFront.

D

Update the CloudFront cache policy to enable case-insensitive header matching.

Question #301 / 529

A company is developing a serverless application using AWS Lambda. Each customer must have a customizable request limit that resets daily, with some customers allowed higher limits during peak hours. The solution must enforce accurate per-customer limits while accommodating varying usage patterns.

Which solution meets these requirements?

A

Deploy an Amazon API Gateway REST API integrated with Lambda. Assign each customer a usage plan with a daily quota and adjustable rate limits. Generate API keys linked to their respective usage plans for authentication and quota enforcement.

B

Use Amazon API Gateway HTTP API with Lambda integration. Configure route-specific throttling limits and attach usage plans with API keys. Assign each customer a unique API key tied to their throttling settings.

C

Create Lambda aliases with provisioned concurrency for each customer. Distribute unique Lambda function URLs for each alias, applying concurrency limits as the daily request quota. Share URLs with relevant customers.

D

Set up an Application Load Balancer (ALB) with Lambda as a target. Use AWS WAF rate-based rules linked to each customer's IP range to enforce request quotas. Configure rules to reset limits daily.

Sample Questions

Question #50 / 557

A developer is testing error handling for a mobile app that interacts with an Amazon API Gateway REST API. The developer needs to simulate various HTTP error responses (e.g., 400, 500) during testing without triggering the actual backend service.

Which approach fulfills these requirements with the LEAST operational overhead?

A

Deploy an AWS Lambda function with error-throwing logic. Integrate it with API Gateway using proxy integration.

B

Set up an Amazon ECS cluster with containers that return predefined error codes. Configure API Gateway to route to the ECS service.

C

Modify the API Gateway resource methods to return hardcoded error responses using gateway responses.

D

Use API Gateway mock integrations with context variables in mapping templates to dynamically generate error responses.

Question #179 / 557

A developer is working on a Java application that runs on Amazon EC2 instances. The developer needs to trace distributed requests to identify latency issues in the application.

Which combination of actions should the developer take to achieve this goal? (Choose two.)

A

Install the Amazon CloudWatch agent on the EC2 instances.

B

Install the AWS X-Ray daemon on the EC2 instances.

C

Configure the application to write JSON-formatted logs to /var/log/CloudWatch.

D

Configure the application to write trace data to /var/log/X-Ray.

E

Install and configure the AWS X-Ray SDK for Java in the application.
