AWS Certified Developer - Associate Questions and Answers

Question 101

A company has a web application that contains an Amazon API Gateway REST API. A developer has created an AWS CloudFormation template for the initial deployment of the application. The developer has deployed the application successfully as part of an AWS CodePipeline continuous integration and continuous delivery (CI/CD) process. All resources and methods are available through the deployed stage endpoint.

The CloudFormation template contains the following resource types:

• AWS::ApiGateway::RestApi

• AWS::ApiGateway::Resource

• AWS::ApiGateway::Method

• AWS:ApiGateway::Stage

• AWS::ApiGateway:;Deployment

The developer adds a new resource to the REST API with additional methods and redeploys the template. CloudFormation reports that the deployment is successful and that the stack is in the UPDATE_COMPLETE state. However, calls to all new methods are returning 404 (Not Found) errors.

What should the developer do to make the new methods available?

Options:

A.

Specify the disable-rollback option during the update-stack operation.

B.

Unset the Cloud Forma lion stack failure options.

C.

Add an AWS CodeBuild stage lo CodePipeline to run the aws apigateway create-deployment AWS CLI command.

D.

Add an action to CodePipeline to run the aws cloudfront create-invalidation AWS CLI command.

Question 102

A developer designed an application on an Amazon EC2 instance The application makes API requests to objects in an Amazon S3 bucket

Which combination of steps will ensure that the application makes the API requests in the MOST secure manner? (Select TWO.)

Question 103

A developer is building an application that stores sensitive user data. The application includes an Amazon CloudFront distribution and multiple AWS Lambda functions that handle user requests.

User requests contain more than 20 data fields. Each application transaction includes sensitive data that must be encrypted. Only specific parts of the application must be able to decrypt the data.

Which solution will meet these requirements?

Options:

A.

Associate the CloudFront distribution with a Lambda@Edge function. Configure the function to perform field-level asymmetric encryption by using a user-defined RSA public key stored in AWS KMS.

B.

Integrate AWS WAF with CloudFront and use a Lambda function with self-managed keys to encrypt and decrypt the data.

C.

Configure the CloudFront distribution to use field-level encryption. Create an asymmetric AWS KMS key and configure CloudFront to use the key.

D.

Configure CloudFront to require HTTPS and require users to access content by using signed URLs or signed cookies.

Question 104

A developer has written a distributed application that uses micro services. The microservices are running on Amazon EC2 instances. Because of message volume, the developer is unable to match log output from each microservice to a specific transaction. The developer needs to analyze the message flow to debug the application.

Which combination of steps should the developer take to meet this requirement? (Select TWO.)

Options:

A.

Download the AWS X-Ray daemon. Install the daemon on an EC2 instance. Ensure that the EC2 instance allows UDP traffic on port 2000.

B.

Configure an interface VPC endpoint to allow traffic to reach the global AWS X-Ray daemon on TCP port 2000.

C.

Enable AWS X-Ray. Configure Amazon CloudWatch to push logs to X-Ray.

D.

Add the AWS X-Ray software development kit (SDK) to the microservices. Use X-Ray to trace requests that each microservice makes.
