Question #252 / 529

A company operates an Amazon Aurora PostgreSQL DB cluster in a single AWS Region. The compliance team needs to continuously audit all data access and modification activities across all databases.

Which solution will meet this requirement?

A

Configure an AWS DMS CDC task with the Aurora cluster as the source and Kinesis Data Firehose as the target. Use Firehose to load data into Amazon OpenSearch Service for audit analysis.

B

Activate a database activity stream on the Aurora cluster, which sends events to Amazon EventBridge. Set up a Lambda function triggered by EventBridge to decrypt and store the activities in Amazon S3.

C

Enable a database activity stream on the Aurora cluster, directing the stream to an Amazon Kinesis data stream. Use Amazon Kinesis Data Firehose to consume the stream and store the data in Amazon S3 for auditing purposes.

D

Create an AWS DMS CDC task sourcing from Aurora and targeting Kinesis Data Firehose. Use Firehose to deliver data to Amazon Redshift, then query Redshift for audit logs.

Question #409 / 529

A company is deploying Amazon EC2 instances that access an Amazon RDS for MySQL database across development and production environments. The company must avoid storing credentials in application code and ensure automatic password rotation. Which solution meets these requirements?

A

Store the database credentials for both environments in AWS Systems Manager Parameter Store. Encrypt the credentials using AWS KMS. Within the application code, retrieve the credentials from Parameter Store using the AWS SDK. Grant the EC2 instances' IAM roles access to the Parameter Store parameters and the KMS key.

B

Store the database credentials for both environments in AWS Secrets Manager with distinct secret entries for development and production. Enable automatic rotation. Reference the Secrets Manager secret ARNs as environment variables for the EC2 instances.

C

Store the database credentials in AWS Key Management Service (AWS KMS) with separate keys for development and production. Enable key rotation. Reference the KMS key IDs as environment variables for the EC2 instances.

D

Store the credentials in separate Amazon S3 buckets for development and production. Enable server-side encryption with AWS KMS. Use bucket naming conventions to allow EC2 instances to retrieve environment-specific credentials. Grant the EC2 instances' IAM roles access to the corresponding S3 buckets.

Sample Questions

Question #131 / 557

A company is building a serverless backend for a mobile application using Amazon API Gateway and AWS Lambda. The team needs to deploy updates to a fully isolated, instrumented staging environment for validation before promoting changes to production. Which approach meets these requirements?

A

Deploy a single API Gateway stage. Maintain separate Lambda functions for each environment. Require API consumers to include a header specifying the target environment and corresponding Lambda function.

B

Create multiple API Gateway stages. Use a shared Lambda function across environments. Implement conditional logic in the Lambda code using stage-specific environment variables to handle environment differences.

C

Implement multiple API Gateway stages. Deploy dedicated Lambda functions for each environment. Use API Gateway stage variables to dynamically map API integrations to the appropriate Lambda function version per environment.

D

Use one API Gateway stage. Instruct clients to pass an environment identifier in the request body. Modify the Lambda function to execute environment-specific code paths based on the received identifier.

Question #116 / 557

A company manages hundreds of AWS Lambda functions that must be tested via Lambda function URLs by the QA team. The security team mandates that all access must be authenticated using IAM credentials. A developer needs to configure the Lambda functions' authentication to permit the QA IAM group to invoke them via the public URLs.

Which solution meets these requirements?

A

Create a CLI script to enable Lambda function URLs with AWS_IAM authentication for all functions. Run another script to create an IAM identity-based policy allowing the lambda:InvokeFunctionUrl action on all Lambda ARNs. Attach this policy to the QA IAM group.

B

Create a CLI script to enable Lambda function URLs with NONE authentication for all functions. Run another script to create a resource-based policy for each Lambda allowing the lambda:InvokeFunctionUrl action, referencing the QA IAM group's ARN. Attach the policies to the respective Lambda functions.

C

Create a CLI script to enable Lambda function URLs with AWS_IAM authentication for all functions. Run another script to loop through each Lambda and create a resource-based policy allowing the lambda:InvokeFunctionUrl action for the QA IAM group's ARN. Attach the policies to the Lambdas.

D

Create a CLI script to enable Lambda function URLs with NONE authentication for all functions. Run another script to create an IAM identity-based policy allowing the lambda:InvokeFunctionUrl action on all Lambda ARNs. Attach the policy to the QA IAM group.
