Question No. 1

A developer needs to perform geographic load testing of an API. The developer must deploy resources to multiple AWS Regions to support the load testing of the API.

How can the developer meet these requirements without additional application code?

ACreate and deploy an AWS Lambda function in each desired Region. Configure the Lambda function to create a stack from an AWS CloudFormation template in that Region when the function is invoked.

BCreate an AWS CloudFormation template that defines the load test resources. Use the AWS CLI create-stack-set command to create a stack set in the desired Regions.

CCreate an AWS Systems Manager document that defines the resources. Use the document to create the resources in the desired Regions.

DCreate an AWS CloudFormation template that defines the load test resources. Use the AWS CLI deploy command to create a stack from the template in each Region.

Show Answer

Correct Answer: B

AWS CloudFormation is a service that allows developers to model and provision AWS resources using templates. A CloudFormation template can define the load test resources, such as EC2 instances, load balancers, and Auto Scaling groups. A CloudFormation stack set is a collection of stacks that can be created and managed from a single template in multiple Regions and accounts. The AWS CLI create-stack-set command can be used to create a stack set from a template and specify the Regions where the stacks should be created.

Question No. 4

A developer created a Node.js-based AWS Lambda function by using a container image of an AWS OS-only base image. There is a new security patch for Node.js that must be patched to the new Lambda function.

Which solution will meet this requirement?

ASet the runtime update mode of the Lambda function to Auto.

BPatch the runtime version by redeploying the same version of the Lambda function.

CRebuild the Lambda container code with the latest version of the AWS OS base image. Publish a new version of the Lambda function.

DRebuild the Lambda container code with the latest Node.js patch version. Publish a new version of the Lambda function.

Show Answer

Correct Answer: D

Comprehensive Detailed Explanation with all AWS Reference

Why Option D is Correct:

When using a container-based AWS Lambda function, you are responsible for updating the base image for runtime patches. Rebuilding the container with the latest Node.js patch version ensures the function is updated with the required security patches. Publishing a new version of the Lambda function makes the updated image available for use.

Why Other Options are Incorrect:

Option A: The runtime update mode applies to functions using AWS-managed runtimes, not container-based runtimes.

Option B: Redeploying the same version of the Lambda function does not apply the security patch.

Option C: Rebuilding with the AWS OS base image does not guarantee that the latest Node.js patch version is included.

Question No. 5

A company has a serverless application that uses Amazon API Gateway backed by AWS Lambda proxy integration. The company is developing several backend APIs. The company needs a landing page to provide an overview of navigation to the APIs.

A developer creates a new /LandingPage resource and a new GET method that uses mock integration.

What should the developer do next to meet these requirements?

AConfigure the integration request mapping template with Content-Type of text/html and statusCode of 200. Configure the integration response mapping template with Content-Type of application/json. In the integration response mapping template, include the LandingPage HTML code that references the APIs.

BConfigure the Integration request mapping template with Content-Type of application/json. In the integration request mapping template, include the LandingPage HMTL code that references the APIs. Configure the integration response mapping template with Content-Type of text/html and statusCode of 200.

CConfigure the integration request mapping template with Content-Type of application/json and statusCode of 200. Configure the integration response mapping template with Content-Type of text/html. In the integration response mapping template, include the LandingPage HTML code that references the APIs.

DConfigure the integration request mapping template with Content-Type of text/html. In the integration request mapping template, include the LandingPage HTML code that references the APIs.
