Question: 1

A developer is creating an application that includes an Amazon API Gateway REST API in the us-east-2 Region. The developer wants to use Amazon CloudFront and a custom domain name for the API. The developer has acquired an SSL/TLS certificate for the domain from a third-party provider.

How should the developer configure the custom domain for the application?

AImport the SSL/TLS certificate into AWS Certificate Manager (ACM) in the same Region as the API. Create a DNS A record for the custom domain.

BImport the SSL/TLS certificate into CloudFront. Create a DNS CNAME record for the custom domain.

CImport the SSL/TLS certificate into AWS Certificate Manager (ACM) in the same Region as the API. Create a DNS CNAME record for the custom domain.

DImport the SSL/TLS certificate into AWS Certificate Manager (ACM) in the us-east-1 Region. Create a DNS CNAME record for the custom domain.

Question: 2

A developer is designing a serverless application with two AWS Lambda functions to process photos. One Lambda function stores objects in an Amazon S3 bucket and stores the associated metadata in an Amazon DynamoDB table. The other Lambda function fetches the objects from the S3 bucket by using the metadata from the DynamoDB table. Both Lambda functions use the same Python library to perform complex computations and are approaching the quota for the maximum size of zipped deployment packages.

What should the developer do to reduce the size of the Lambda deployment packages with the LEAST operational overhead?

APackage each Python library in its own .zip file archive. Deploy each Lambda function with its own copy of the library.

BCreate a Lambda layer with the required Python library. Use the Lambda layer in both Lambda functions.

CCombine the two Lambda functions into one Lambda function. Deploy the Lambda function as a single .zip file archive.

DDownload the Python library to an S3 bucket. Program the Lambda functions to reference the object URLs.

Question: 3

A developer has written an AWS Lambda function. The function is CPU-bound. The developer wants to ensure that the function returns responses quickly.

How can the developer improve the function's performance?

AIncrease the function's CPU core count.

BIncrease the function's memory.

CIncrease the function's reserved concurrency.

DIncrease the function's timeout.

Question: 4

A company is migrating legacy internal applications to AWS. Leadership wants to rewrite the internal employee directory to use native AWS services. A developer needs to create a solution for storing employee contact details and high-resolution photos for use with the new application.

Which solution will enable the search and retrieval of each employee's individual details and high-resolution photos using AWS APIs?

AEncode each employee's contact information and photos using Base64. Store the information in an Amazon DynamoDB table using a sort key.

BStore each employee's contact information in an Amazon DynamoDB table along with the object keys for the photos stored in Amazon S3.

CUse Amazon Cognito user pools to implement the employee directory in a fully managed software-as-a-service (SaaS) method.

DStore employee contact information in an Amazon RDS DB instance with the photos stored in Amazon Elastic File System (Amazon EFS).

Question: 5

A company hosts a client-side web application for one of its subsidiaries on Amazon S3. The web application can be accessed through Amazon CloudFront from https://www.example.com. After a successful rollout, the company wants to host three more client-side web applications for its remaining subsidiaries on three separate S3 buckets.

To achieve this goal, a developer moves all the common JavaScript files and web fonts to a central S3 bucket that serves the web applications. However, during testing, the developer notices that the browser blocks the JavaScript files and web fonts.

What should the developer do to prevent the browser from blocking the JavaScript files and web fonts?

ACreate four access points that allow access to the central S3 bucket. Assign an access point to each web application bucket.

BCreate a bucket policy that allows access to the central S3 bucket. Attach the bucket policy to the central S3 bucket.

CCreate a cross-origin resource sharing (CORS) configuration that allows access to the central S3 bucket. Add the CORS configuration to the central S3 bucket.

DCreate a Content-MD5 header that provides a message integrity check for the central S3 bucket. Insert the Content-MD5 header for each web application request.
