Sample Questions

Question #999 / 1019

A company operates a blog platform on AWS, utilizing an Application Load Balancer, an Auto Scaling group of EC2 instances, and a Single-AZ Amazon RDS MySQL database. Users experience delays when loading blog posts, which are stored in infrequently updated tables. Monitoring shows high CPU usage on the RDS instance during peak traffic. What should the solutions architect do to enhance performance?

A

Migrate the blog posts to Amazon Aurora with read replicas and use the replicas for read operations.

B

Deploy Amazon ElastiCache for Redis to cache blog posts, implementing lazy loading.

C

Adjust the Auto Scaling group to increase EC2 instances when RDS CPU exceeds a threshold.

D

Enable Multi-AZ deployment for RDS and modify the application to reduce query frequency.

Question #266 / 1019

A company operates a global e-commerce platform on AWS, requiring low latency to ensure fast checkout processes. The application is deployed across multiple AWS Regions using Amazon EC2 instances in Auto Scaling groups behind Application Load Balancers (ALBs). The solutions architect must implement a solution to monitor application health and automatically redirect users to the nearest healthy Region.

Which solution meets these requirements?

A

Configure AWS Global Accelerator with a listener on the application's port, attaching Regional endpoints with the ALBs in each Region.

B

Set up an Amazon CloudFront distribution with the ALB as the origin, configuring cache behaviors based on origin headers and using Lambda@Edge for request routing.

C

Use Amazon Route 53 with latency-based routing policies and configure health checks for each ALB endpoint.

D

Implement an Amazon API Gateway with regional endpoints and configure canary deployments to shift traffic between Regions.

AWS Certified Developer – Associate

Sample Questions

Question #251 / 557

A developer has created an image processing application using Amazon API Gateway, AWS Lambda, and Amazon S3. Users periodically upload high-resolution images and wait for the processing status to be displayed on a dashboard. The processing is resource-intensive and time-consuming for large images. Users uploading multiple images have to wait and refresh the dashboard to check the status. The developer needs to update the dashboard in real-time without requiring a full reload.

What is the MOST operationally efficient solution that meets these requirements?

A

Integrate the client with an API Gateway WebSocket API. Associate the uploaded images with the WebSocket connection ID. Push the processing status to the connection ID upon completion to trigger a real-time dashboard update.

B

Deploy an Amazon EC2 micro instance to host a WebSocket server. Forward uploaded images and user details to the EC2 instance after upload. Use the WebSocket server to notify the client for real-time dashboard updates when processing finishes.

C

Store the user\u2019s email address with each uploaded image. Use Amazon Simple Notification Service (Amazon SNS) to send an email notification to the user when processing completes, prompting them to check the dashboard.

D

Save uploaded images and user details in Amazon DynamoDB. Configure Amazon DynamoDB Streams with Amazon Simple Notification Service (Amazon SNS) to send browser notifications and update the user interface automatically.

Question #468 / 557

A company operates an application on Amazon EC2 instances within an Auto Scaling group. The application's workload fluctuates significantly during peak hours.

The company needs to gather comprehensive metrics from the EC2 instances to optimize instance performance. Additionally, they must monitor custom metrics from the application to maintain operational efficiency.

Which solution fulfills these requirements?

A

Deploy the AWS X-Ray agent on the instances. Configure the agent to collect EC2 instance performance data and custom application metrics.

B

Install the Amazon CloudWatch agent on the instances. Configure the agent to collect detailed EC2 instance metrics and custom application metrics.

C

Integrate the AWS SDK into the application code. Modify the application to use the SDK for publishing EC2 instance metrics and custom application metrics.

D

Enable AWS CloudTrail to capture and analyze EC2 instance performance data and custom application metrics.
