What should the Development team do to achieve this?

• A.Add annotations to the segment document and the code
• B.Add metadata to the segment document and the code
• C.Configure the necessary X-Ray environment variables
• D.Install required plugins for the appropriate AWS SDK

A security review for a software company's application infrastructure shows that there is no test coverage in any of the company's deployment pipelines. A developer must fix this issue as soon as possible. The company has been integrating the AWS Cloud Development Kit (AWS CDK) into the deployment process. However, much of the pipeline still uses AWS CloudFormation templates. The developer needs to add test coverage to all the deployment code.
Which solution will meet these requirements with the LEAST amount of configuration?

• A.Write unit tests by using the AWS CDK assertions module. Create CloudFormation template instances by using the module's Template class for the existing CloudFormation templates and the module's Capture class for the CDK stacks.
• B.Convert the CloudFormation templates into CDK stacks by using the AWS CDK Cfnlnclude construct. Write unit tests against the templates by using CloudFormation rule assertions.
• C.Convert the CDK stacks into CloudFormation templates by using the AWS CDK Cfnlnclude construct Write unit tests against the templates by using CloudFormation rule assertions
• D.Write unit tests by using the AWS CDK assertions module. Create CloudFormation template instances by using the module's Template.fromStringO method for the existing CloudFormation templates and the module's Template fromStackQ method for the CDK stacks.

A Developer is writing an application that runs on Amazon EC2 instances in an Auto scaling group. The application data is stored in an Amazon DynamoDB table and records are constantly updated by all instances. An instance sometimes retrieves old dat a. The Developer wants to correct this by making sure the reads are strongly consistent.
How can the developer accomplish this?

• A.Set consistentRead to true when calling Getitem.
• B.Create a new DynamoDB Accelerator (DAX) table.
• C.Set consistency to strong when calling Update Table.
• D.Use the Getshardlterator command.

A developer is writing a web application that allows users to sign in. The application will run on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances will run in an Auto Scaling group across multiple Availability Zones.
How can the developer ensure that users stay signed in when the Auto Scaling group is scaled down?

• A.Enable sticky sessions on the ALB target group.
• B.Enable deregistration delay on the ALB target group.
• C.Create an Amazon Elastic Block Store (Amazon EBS) volume. Use EBS Multi-Attach to attach the volume to all instances in the Auto Scaling group. Configure the application to use the volume to store session state such as login status.
• D.Create an Amazon DynamoDB table. Configure the application to use the DynamoDB table to store session state such as login status.
