Question 1

A company has an on-premises application that is written in Go. A DevOps engineer must move the application to AWS. The company's development team wants to enable blue/green deployments and perform A/B testing.

Which solution will meet these requirements?

A : Deploy the application on an Amazon EC2 instance, and create an AMI of the instance. Use the AMI to create an automatic scaling launch configuration that is used in an Auto Scaling group. Use Elastic Load Balancing to distribute traffic. When changes are made to the application, a new AMI will be created, which will initiate an EC2 instance refresh.

B : Use Amazon Lightsail to deploy the application. Store the application in a zipped format in an Amazon S3 bucket. Use this zipped version to deploy new versions of the application to Lightsail. Use Lightsail deployment options to manage the deployment.

C : Use AWS CodeArtifact to store the application code. Use AWS CodeDeploy to deploy the application to a fleet of Amazon EC2 instances. Use Elastic Load Balancing to distribute the traffic to the EC2 instances. When making changes to the application, upload a new version to CodeArtifact and create a new CodeDeploy deployment.

D : Use AWS Elastic Beanstalk to host the application. Store a zipped version of the application in Amazon S3. Use that location to deploy new versions of the application. Use Elastic Beanstalk to manage the deployment options

Answer: D

Question 2

A software development company is using AWS CodeCommit, AWS CodeBuild, AWS CodeDeploy, and AWS CodePipeline for its CI/CD process. To further improve their systems, they need to implement a solution that automatically detects and reacts to changes in the state of their deployments in AWS CodeDeploy. Any changes must be rolled back automatically if the deployment process fails, and a notification must be sent to the DevOps Team's Slack channel for easy monitoring.

Which of the following is the MOST suitable configuration that you should implement to satisfy this requirement?

A : Set up a CloudWatch Events rule to monitor AWS CodeDeploy operations with a Lambda function as a target. Configure the rule to send out a message to the DevOps Team's Slack Channel in the event that the deployment fails. Configure AWS CodeDeploy to use the Roll back when a deployment fails setting.

B : Monitor the API calls in the CodeDeploy project using AWS CloudTrail. Send a message to the DevOps Team's Slack Channel when the PutLifecycleEventHookExecutionStatus API call has been detected. Rollback the changes by using the AWS CLI.

C : Set up a CloudWatch Alarm that tracks the CloudWatch metrics of the CodeDeploy project. Configure the CloudWatch Alarm to automatically send out a message to the DevOps Team's Slack Channel when the deployment fails. Configure AWS CodeDeploy to use the Roll back when alarm thresholds are met setting.

D : Configure a CodeDeploy agent to send notification to the DevOps Team's Slack Channel when the deployment fails. Configure AWS CodeDeploy to automatically roll back whenever the deployment is not successful.

Answer: A

Question 3

A DevOps engineer is supporting early-stage development for a developer platform running on Amazon EKS. Recently, the platform has experienced an increased rate of container restart failures. The DevOps engineer wants diagnostic information to isolate and resolve issues. Which solution will meet this requirement?

A : Configure CloudWatch dashboards using default EKS service metrics.

B : Configure AWS CloudTrail for the EKS cluster.

C : Configure CloudTrail Insights for the EKS cluster.

D : Configure Amazon CloudWatch Container Insights for the EKS cluster by enabling the CloudWatch Observability add-on.

Answer: D

Question 4

A development team manually builds a local artifact. The development team moves the artifact to an Amazon S3 bucket to support an application. The application has a local cache that must be cleared when the development team deploys the application to Amazon EC2 instances. For each deployment, the development team runs a command to clear the cache, download the artifact from the S3 bucket, and unzip the artifact to complete the deployment. The development team wants to migrate the deployment process to a CI/CD process and to track the progress of each deployment. Which combination of actions will meet these requirements with the MOST operational efficiency? (Select THREE.)

A : Set up an AWS CodeConnections compatible Git repository. Allow developers to merge code into the repository. Use AWS CodeBuild to build an artifact and copy the object into the S3 bucket. Configure CodeBuild to run for every merge into the main branch.

B : Create a custom script to clear the cache. Specify the script in the BeforeInstall lifecycle hook in the AppSpec file.

C : Create user data for each EC2 instance that contains the cache clearing script. Test the application after deployment. If the deployment is not successful, then redeploy.

D : Use AWS CodePipeline to deploy the application. Set up an AWS CodeConnections compatible Git repository. Allow developers to merge code into the repository as a source for the pipeline.

E : Use AWS CodeBuild to build the artifact and place the artifact in the S3 bucket. Use AWS CodeDeploy to deploy the artifact to EC2 instances.

F : Use AWS Systems Manager to fetch the artifact from the S3 bucket and to deploy the artifact to all the EC2 instances.

Answer: B,D,E

Question 5

A company has several AWS accounts. An Amazon Connect instance runs in each account. The company uses an Amazon EventBridge default event bus in each account for event handling. A DevOps team needs to receive all the Amazon Connect events in a single DevOps account. Which solution meets these requirements?

A : Update the resource-based policy of the default event bus in each account to allow the DevOps account to replay events. Configure an EventBridge rule in the DevOps account that matches Amazon Connect events and has a target of the default event bus in the other accounts.

B : Update the resource-based policy of the default event bus in each account to allow the DevOps account to receive events. Configure an EventBridge rule in the DevOps account that matches Amazon Connect events and has a target of the default event bus in the other accounts.

C : Update the resource-based policy of the default event bus in the DevOps account. Update the policy to allow events to be received from the accounts. Configure an EventBridge rule in each account that matches Amazon Connect events and has a target of the DevOps account's default event bus

D : Update the resource-based policy of the default event bus in the DevOps account. Update the policy to allow events to be replayed by the accounts. Configure an EventBridge rule in each account that matches Amazon Connect events and has a target of the DevOps account's default event bus.
