Question 1

A developer has a legacy application that is hosted on-premises. Other applications hosted on AWS depend on the on-premises application for proper functioning.

How can the developer accomplish this?

Options:

A.

Install an AWS SDK on the on-premises server to automatically send logs to CloudWatch.

B.

Download the CloudWatch agent to the on-premises server. Configure the agent to use IAM user credentials with permissions for CloudWatch.

C.

Upload log files from the on-premises server to Amazon S3 and have CloudWatch read the files.

D.

Upload log files from the on-premises server to an Amazon EC2 instance and have the instance forward the logs to CloudWatch.

Question 2

A developer has observed an increase in bugs in the AWS Lambda functions that a development team has deployed in its Node.js application.

To minimize these bugs, the developer wants to implement automated testing of Lambda functions in an environment that closely simulates the Lambda environment.

The developer needs to give other developers the ability to run the tests locally. The developer also needs to integrate the tests into the team's continuous integration and continuous delivery (CI/CD) pipeline before the AWS Cloud Development Kit (AWS CDK) deployment.

Which solution will meet these requirements?

Options:

A.

Create sample events based on the Lambda documentation. Create automated test scripts that use the cdk local invoke command to invoke the Lambda functions. Check the response. Document the test scripts for the other developers on the team. Update the CI/CD pipeline to run the test scripts.

B.

Install a unit testing framework that reproduces the Lambda execution environment. Create sample events based on the Lambda documentation. Invoke the handler function by using a unit testing framework. Check the response. Document how to run the unit testing framework for the other developers on the team. Update the CI/CD pipeline to run the unit testing framework.

C.

Install the AWS Serverless Application Model (AWS SAM) CLI tool. Use the sam local generate-event command to generate sample events for the automated tests. Create automated test scripts that use the sam local invoke command to invoke the Lambda functions. Check the response. Document the test scripts for the other developers on the team. Update the CI/CD pipeline to run the test scripts.

D.

Create sample events based on the Lambda documentation. Create a Docker container from the Node.js base image to invoke the Lambda functions. Check the response. Document how to run the Docker container for the other developers on the team. Update the CllCD pipeline to run the Docker container.

Question 3

A developer writes an AWS Lambda function that processes new object uploads to an Amazon S3 bucket. The Lambda function runs for approximately 30 seconds. The function runs as expected under normal load conditions. Other Lambda functions in the AWS account also run as expected.

Occasionally, up to 500 new objects are written to the bucket every minute. Each new object write invokes the processing Lambda function during the high-volume periods through an event notification.

The developer must ensure that the processing function continues to run as expected during the high-volume periods.

Which solution will meet this requirement?

Options:

A.

Modify the function's timeout setting.

B.

Add an additional Lambda layer to optimize the code execution.

C.

Configure a reserved concurrency quota for the function.

D.

Decrease the function's memory allocation.
