A company is developing a latency-sensitive application. Part of the application includes several AWS Lambda functions that need to initialize as quickly as possible. The Lambda functions are written in Java and contain initialization code outside the handlers to load libraries, initialize classes, and generate unique IDs.

Which solution will meet the startup performance requirement MOST cost-effectively?

Options:

A.

Move all the initialization code to the handlers for each Lambda function. Activate Lambda SnapStart for each Lambda function. Configure SnapStart to reference the $LATEST version of each Lambda function.

B.

Publish a version of each Lambda function. Create an alias for each Lambda function. Configure each alias to point to its corresponding version. Set up provisioned concurrency configuration for each Lambda function to point to the corresponding alias.

C.

Publish a version of each Lambda function. Set up a provisioned concurrency configuration for each Lambda function to point to the corresponding version. Activate Lambda SnapStart for the published versions of the Lambda functions.

D.

Update the Lambda functions to add a pre-snapshot hook. Move the code that generates unique IDs into the handlers. Publish a version of each Lambda function. Activate Lambda SnapStart for the published versions of the Lambda functions.

Question 80

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:

A.

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

B.

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

C.

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