Sample Questions

Question #455 / 529

A company needs to migrate 50 on-premises legacy Java EE applications to AWS. The applications are monolithic and run on Linux servers.

The company requires a solution that minimizes migration effort, avoids application code modifications, and eliminates infrastructure management. Which option best meets these requirements?

A

Refactor the applications into containers using AWS App2Container. Deploy the containers using Amazon Elastic Container Service (Amazon ECS) with the Fargate launch type.

B

Use AWS Application Migration Service (AWS MGN) to migrate the applications to AWS Elastic Beanstalk. Use Elastic Beanstalk to deploy and manage the applications.

C

Use AWS Application Migration Service (AWS MGN) to migrate the applications to Amazon EC2 instances. Manage the applications and infrastructure on EC2.

D

Refactor the applications into containers using AWS App2Container. Deploy the containers using Amazon Elastic Kubernetes Service (Amazon EKS) with the Fargate launch type.

Question #114 / 529

A company has an on-premises monitoring solution using a MySQL database for event persistence. The database struggles to handle increasing data volumes and frequently encounters storage limitations.

The company aims to implement a hybrid solution with a pre-established VPN connection between its network and AWS. The solution must include the following:

- Fully managed AWS services to reduce operational overhead.
- An auto-scaling buffer requiring no administrative effort to handle fluctuating data throughput.
- A visualization tool for near-real-time dashboards to monitor events.
- Compatibility with semi-structured JSON data and evolving schemas.

Which combination of components will meet these requirements? (Choose two.)

A

Use Amazon Kinesis Data Firehose to buffer events. Deploy an AWS Lambda function to process and transform the data.

B

Create an Amazon Kinesis data stream to buffer events. Deploy an AWS Lambda function to process and transform the data.

C

Configure an Amazon Aurora MySQL DB cluster to ingest events. Use Amazon QuickSight to build near-real-time dashboards from the database.

D

Use Amazon OpenSearch Service (Amazon OS) to store events. Utilize the integrated Kibana interface to create near-real-time visualizations.

E

Configure an Amazon DocumentDB cluster to ingest events. Use Amazon QuickSight to visualize data from the database in near-real time.

AWS Certified Developer – Associate

Sample Questions

Question #467 / 557

A developer updates an AWS Lambda function by adding several large libraries, resulting in a deployment package that exceeds the direct upload limit. The developer attempts to deploy the updated .zip file via the Lambda console but receives the following error:

An error occurred (RequestEntityTooLargeException) when calling the UpdateFunctionCode operation

Which solutions will allow the developer to deploy the updated code successfully? (Choose two.)

A

Upload the .zip file to Amazon S3. Use the Lambda console to update the function code by specifying the S3 bucket and object key.

B

Contact AWS Support to request an increase to the Lambda deployment package size limit.

C

Use the AWS CLI to run the update-function-code command with the --publish flag, referencing the local .zip file.

D

Package the Lambda function as a Docker container image, upload it to Amazon ECR, and create a new Lambda function using the container image.

E

Enable code signing for the Lambda function, digitally sign the .zip file, and redeploy it via the console.

Question #286 / 557

A developer is using AWS Step Functions to orchestrate a workflow where each step is defined as an Amazon SNS publish task. The developer observes that state machine executions fail in the PublishNotification task with either an AccessDeniedException error or a ThrottlingException error.

The developer wants the state machine to halt execution immediately when encountering an AccessDeniedException error. For ThrottlingException errors, the state machine should retry the PublishNotification task once after a 15-second interval. If the retry fails, the execution should terminate.

How can the developer implement this error-handling logic while minimizing complexity in the state machine definition?

A

Add a catcher to the PublishNotification task for AccessDeniedException to stop execution. Add another catcher for ThrottlingException with a 15-second Delay task and route back to PublishNotification.

B

Create a retrier for the PublishNotification task with error type AccessDeniedException and max attempts 0. Add a separate retrier for ThrottlingException with max attempts 1 and interval 15 seconds.

C

Add a retrier to the PublishNotification task configured for ThrottlingException with interval=15 and max attempts=1. Add a catcher for AccessDeniedException to stop execution.

D

Duplicate the PublishNotification task as RetryPublish. Add a catcher to the original task for ThrottlingException pointing to RetryPublish, and a catcher for AccessDeniedException to stop execution.
