Question # 115

A company ' s application uses a fleet of Amazon EC2 On-Demand Instances to analyze and process data. The EC2 instances are in an Auto Scaling group. The Auto Scaling group is a target group for an Application Load Balancer (ALB). The application analyzes critical data that cannot tolerate interruption. The application also analyzes noncritical data that can withstand interruption.

The critical data analysis requires quick scalability in response to real-time application demand. The noncritical data analysis involves memory consumption. A DevOps engineer must implement a solution that reduces scale-out latency for the critical data. The solution also must process the noncritical data.

Which combination of steps will meet these requirements? (Select TWO.)

Options:

A.

For the critical data, modify the existing Auto Scaling group. Create a warm pool instance in the stopped state. Define the warm pool size. Create a new version of the launch template that has detailed monitoring enabled. use Spot Instances.

B.

For the critical data, modify the existing Auto Scaling group. Create a warm pool instance in the stopped state. Define the warm pool size. Create a new version of the launch template that has detailed monitoring enabled. Use On-Demand Instances.

C.

For the critical data. modify the existing Auto Scaling group. Create a lifecycle hook to ensure that bootstrap scripts are completed successfully. Ensure that the application on the instances is ready to accept traffic before the instances are registered. Create a new version of the launch template that has detailed monitoring enabled.

D.

For the noncritical data, create a second Auto Scaling group that uses a launch template. Configure the launch template to install the unified Amazon CloudWatch agent and to configure the CloudWatch agent with a custom memory utilization metric. Use Spot Instances. Add the new Auto Scaling group as the target group for the ALB. Modify the application to use two target groups for critical data and noncritical data.

E.

For the noncritical data, create a second Auto Scaling group. Choose the predefined memory utilization metric type for the target tracking scaling policy. Use Spot Instances. Add the new Auto Scaling group as the target group for the ALB. Modify the application to use two target groups for critical data and noncritical data.

Question # 116

A company builds a container image in an AWS CodeBuild project by running Docker commands. After the container image is built, the CodeBuild project uploads the container image to an Amazon S3 bucket. The CodeBuild project has an IAM service role that has permissions to access the S3 bucket.

A DevOps engineer needs to replace the S3 bucket with an Amazon Elastic Container Registry (Amazon ECR) repository to store the container images. The

DevOps engineer creates an ECR private image repository in the same AWS Region of the CodeBuild project. The DevOps engineer adjusts the IAM service role with the permissions that are necessary to work with the new ECR repository. The DevOps engineer also places new repository information into the docker build command and the docker push command that are used in the buildspec.yml file.

When the CodeBuild project runs a build job, the job fails when the job tries to access the ECR repository.

Which solution will resolve the issue of failed access to the ECR repository?

Options:

A.

Update the buildspec.yml file to log in to the ECR repository by using the aws ecr get-login-password AWS CLI command to obtain an authentication token. Update the docker login command to use the authentication token to access the ECR repository.

B.

Add an environment variable of type SECRETS_MANAGER to the CodeBuild project. In the environment variable, include the ARN of the CodeBuild project ' s IAM service role. Update the buildspec.yml file to use the new environment variable to log in with the docker login command to access the ECR repository.

C.

Update the ECR repository to be a public image repository. Add an ECR repository policy that allows the IAM service role to have access.

D.

Update the buildspec.yml file to use the AWS CLI to assume the IAM service role for ECR operations. Add an ECR repository policy that allows the IAM service role to have access.

Question # 117

A company produces builds for an open source project every day. The company hosts the open source project in a public code repository that the company supports. The company manually invokes a pipeline in AWS CodePipeline to build artifacts for the project. The company wants to make the build artifacts publicly available on a website that the company hosts in an Amazon S3 bucket.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

A.

Create an AWS CodeBuild project. Set the public repository as the source. Use a webhook to rebuild when the company pushes a code change. Configure the artifacts section of the project to use the S3 bucket as the destination. Set up an appropriate path to store build outputs in the bucket. Disable artifact encryption.

B.

Create an AWS CodeBuild project. Set the public repository as the source. Configure the artifacts section of the project to use the S3 bucket as the destination. Ensure that artifact encryption is enabled in the artifacts configuration. Configure an Amazon EventBridge rule to initiate the CodeBuild project on a daily schedule.

C.

Add a new stage to the end of the pipeline. Configure the stage to include an action to publish artifacts to the S3 bucket. Update the pipeline to run in response to pull requests to the public repository.

D.

Add a new stage to the end of the pipeline. Configure the stage to include an action to publish artifacts to the S3 bucket. Create an Amazon EventBridge rule to initiate the pipeline on a daily schedule.

Question # 118

A company runs an application in an Amazon Elastic Container Service (Amazon ECS) service that is associated with an Elastic Load Balancing (ELB) target group. A DevOps engineer updates the service to include a new task definition version. The DevOps engineer notices that the deployment does not finish running. New tasks enter a stopped state soon after the tasks launch. The task definition references an Amazon CloudWatch Logs log group.

Which issues are most likely the cause of the failing deployment? (Select TWO.)

Options:

A.

The target group health check is failing, which causes Amazon ECS to stop the tasks.

B.

The IAM role that the DevOps engineer used to update the ECS service does not have the Amazon ECS RunTask permission.

C.

The CloudWatch Logs log group that is referenced in the task definition does not exist.

D.

The task role does not have the required permissions to launch the task.

E.

An essential container in the ECS task is exiting.

Options:

A.

Apply an SCP to all OUs to deny the cloudtrail:StopLogging action and the cloudtrail:DeleteTrail action.

B.

Create IAM policies in each account to deny the cloudtrail:StopLogging action and the cloudtrail:DeleteTrail action.

Question # 121

A company is using AWS CodeDeploy to automate software deployment. The deployment must meet these requirements:

• A number of instances must be available to serve traffic during the deployment Traffic must be balanced across those instances, and the instances must automatically heal in the event of failure.

• A new fleet of instances must be launched for deploying a new revision automatically, with no manual provisioning.

• Traffic must be rerouted to the new environment to half of the new instances at a time. The deployment should succeed if traffic is rerouted to at least half of the instances; otherwise, it should fail.

• Before routing traffic to the new fleet of instances, the temporary files generated during the deployment process must be deleted.
