Question 32

A company has a web application that uses Amazon API Gateway to route HTTPS requests to AWS Lambda functions. The application uses an Amazon Aurora MySQL database for its data storage. The application has experienced unpredictable surges in traffic that overwhelm the database with too many connection requests. The company wants to implement a scalable solution that is more resilient to database failures.

Which solution will meet these requirements MOST cost-effectively?

Options:

Create an Amazon RDS proxy for the database. Replace the database endpoint with the proxy endpoint in the Lambda functions.

Migrate the database to Amazon DynamoDB tables by using AWS Database Migration Service (AWS DMS).

Review the existing connections. Call MySQL queries to end any connections in the sleep state.

Increase the instance class of the database with more memory. Set a larger value for the max_connections parameter.

Question 33

A company runs a monolithic application in its on-premises data center. The company used Java/Tomcat to build the application. The application uses Microsoft SQL Server as a database.

The company wants to migrate the application to AWS.

Which solution will meet this requirement with the LEAST operational overhead?

Options:

Use AWS App2Container to containerize the application. Deploy the application on Amazon Elastic Kubernetes Service (Amazon EKS). Deploy the database to Amazon RDS for SQL Server. Configure a Multi-AZ deployment.

Containerize the application and deploy the application on a self-managed Kubernetes cluster on an Amazon EC2 instance. Deploy the database on a separate EC2 instance. Set up Microsoft SQL Server Always On availability groups.

Deploy the frontend of the web application as a website on Amazon S3. Use Amazon DynamoDB for the database tier.

Use AWS App2Container to containerize the application. Deploy the application on Amazon Elastic Kubernetes Service (Amazon EKS). Use Amazon DynamoDB for the database tier.

Question 34

A company provides a trading platform to customers. The platform uses an Amazon API Gateway REST API, AWS Lambda functions, and an Amazon DynamoDB table. Each trade that the platform processes invokes a Lambda function that stores the trade data in Amazon DynamoDB. The company wants to ingest trade data into a data lake in Amazon S3 for near real-time analysis. Which solution will meet these requirements with the LEAST operational overhead?

Options:

Use Amazon DynamoDB Streams to capture the trade data changes. Configure DynamoDB Streams to invoke a Lambda function that writes the data to Amazon S3.

Use Amazon DynamoDB Streams to capture the trade data changes. Configure DynamoDB Streams to invoke a Lambda function that writes the data to Amazon Data Firehose. Write the data from Data Firehose to Amazon S3.

Enable Amazon Kinesis Data Streams on the DynamoDB table to capture the trade data changes. Configure Kinesis Data Streams to invoke a Lambda function that writes the data to Amazon S3.

Enable Amazon Kinesis Data Streams on the DynamoDB table to capture the trade data changes. Configure a data stream to be the input for Amazon Data Firehose. Write the data from Data Firehose to Amazon S3.

Question 35

Question:

A healthcare company uses an Amazon EMR cluster to process patient data. The data must be encrypted in transit and at rest. Local volumes in the cluster also need to be encrypted. Which solution will meet these requirements?

Options:

Options:

Create Amazon EBS volumes. Enable encryption. Attach the volumes to the existing EMR cluster.

Create an EMR security configuration that encrypts the data and the volumes as required.

Create an EC2 instance profile for the EMR instances. Configure the instance profile to enforce encryption.

Create a runtime role that has a trust policy for the EMR cluster.
