Question 24

A developer is building an application that gives users the ability to view bank account from multiple sources in a single dashboard.

The developer wants a solution that will store the API credentials with minimal operational overhead.

When solution will meet these requirements?

Options:

Add an AWS Secrets Manager GenerateSecretString resource to the CloudFormation template. Set the value to reference new credentials to the Cloudformation resource.

Use the AWS SDK ssm PutParameter operation in the Lambda function from the existing, custom resource to store the credentials as a parameter. Set the parameter value to reference the new credentials. Set ma parameter type to SecureString.

Add an AWS Systems Manager Parameter Store resource to the CloudFormation template. Set the CloudFormation resource value to reference the new credentials Set the resource NoEcho attribute to true.

Use the AWS SDK ssm PutParameter operation in the Lambda function from the existing custom resources to store the credentials as a parameter. Set the parameter value to reference the new credentials. Set the parameter NoEcho attribute to true.

Question 25

A company is migrating an on-premises database to Amazon RDS for MySQL. The company has read-heavy workloads. The company wants to refactor the code to achieve optimum read performance for queries.

Which solution will meet this requirement with LEAST current and future effort?

Options:

Use a multi-AZ Amazon RDS deployment. Increase the number of connections that the code makes to the database or increase the connection pool size if a connection pool is in use.

Use a multi-AZ Amazon RDS deployment. Modify the code so that queries access the secondary RDS instance.

Deploy Amazon RDS with one or more read replicas. Modify the application code so that queries use the URL for the read replicas.

Use open source replication software to create a copy of the MySQL database on an Amazon EC2 instance. Modify the application code so that queries use the IP address of the EC2 instance.

They are study materials that are designed to help students prepare for exams and certification tests. They are basically a collection of questions and answers that are likely to appear on the test.

Extremely accurate. They constantly update their materials with the latest exam questions and answers, so you can be confident that what you're studying is up-to-date.

Carson

Yeah, definitely. I would definitely recommend Cramkey Dumps to anyone who is preparing for an exam.

Me too. They're a lifesaver!

Erik

Hey, I have passed my exam using Cramkey Dumps?

Freyja Dec 14, 2025

Really, what are they? All come in your pool? Please give me more details, I am going to have access their subscription. Please brother, give me more details.

Annabel

I recently used them for my exam and I passed it with excellent score. I am impressed.

Amirah Dec 3, 2025

I passed too. The questions I saw in the actual exam were exactly the same as the ones in the Cramkey Dumps. I was able to answer the questions confidently because I had already seen and studied them.

Question 26

A developer is setting up a deployment pipeline. The pipeline includes an AWS CodeBuild build stage that requires access to a database to run integration tests. The developer is using a buildspec.yml file to configure the database connection. Company policy requires automatic rotation of all database credentials.

Which solution will handle the database credentials MOST securely?

Options:

Retrieve the credentials from variables that are hardcoded in the buildspec.yml file. Configure an AWS Lambda function to rotate the credentials.

Retrieve the credentials from an environment variable that is linked to a SecureString parameter in AWS Systems Manager Parameter Store. Configure Parameter Store for automatic rotation.

Retrieve the credentials from an environment variable that is linked to an AWS Secrets Manager secret. Configure Secrets Manager for automaticrotation.

Retrieve the credentials from an environment variable that contains the connection string in plaintext. Configure an Amazon EventBridge event to rotate the credentials.

Question 27

A developer is writing unit tests tor a new application that will be deployed on AWS. The developer wants to validate all pull requests with unit tests and merge the code with the main branch only when all tests pass

The developer stores the code in AWS CodeCommit and sets up AWS CodeBuild to run the unit tests. The developer creates an AWS Lambda function to start the CodeBuild task. The developer needs to identify the CodeCommit events in an Amazon EventBridge event that can invoke the Lambda function when a pull request is created or updated.

Which CodeCommit event will meet these requirements?
