Question No. 1

A company is running an application on Amazon EC2 instances behind an ELB Application Load Balancer. The instances run in an EC2 Auto Scaling group across multiple Availability Zones. After a recent application update, users are getting HTTP 502 Bad Gateway errors from the application URL. The DevOps Engineer cannot analyze the problem because Auto Scaling is terminating all EC2 instances shortly after launch for being unhealthy. What steps will allow the DevOps Engineer access to one of the unhealthy instances to troubleshoot the deployed application?

ACreate an image from the terminated instance and create a new instance from that image. The Application team can then log into the new instance.

BAs soon as a new instance is created by AutoScaling, put the instance into a Standby state as this will prevent the instance from being terminated.

CAdd a lifecycle hook to your Auto Scaling group to move instances in the Terminating state to the Terminating:Wait state.

DEdit the Auto Scaling group to enable termination protection as this will protect unhealthy instances from being terminated.

Question No. 2

A company is using AWS CodeDeploy to manage its application deployments. Recently, the Development team decided to use GitHub for version control, and the team is looking for ways to integrate the GitHub repository with CodeDeploy. The team also needs to develop a way to automate deployment whenever there is a new commit on that repository. The team is currently deploying new application revisions by manually indicating the Amazon S3 location.

How can the integration be achieved in the MOST efficient way?

ACreate a GitHub webhook to replicate the repository to AWS CodeCommit. Create an AWS CodePipeline pipeline that uses CodeCommit as a source provider and AWS CodeDeploy as a deployment provider. Once configured, commit a change to the GitHub repository to start the first deployment.

BCreate an AWS CodePipeline pipeline that uses GitHub as a source provider and AWS CodeDeploy as a deployment provider. Connect this new pipeline with the GitHub account and instruct CodePipeline to use webhooks in GitHub to automatically start the pipeline when a change occurs.

CCreate an AWS Lambda function to check periodically if there has been a new commit within the GitHub repository. If a new commit is found, trigger a CreateDeployment API call to AWS CodeDeploy to start a new deployment based on the last commit ID within the deployment group.

DCreate an AWS CodeDeploy custom deployment configuration to associate the GitHub repository with the deployment group. During the association process, authenticate the deployment group with GitHub to obtain the GitHub security authentication token. Configure the deployment group options to automatically deploy if a new commit is found. Perform a new commit to the GitHub repository to trigger the first deployment.

Question No. 4

An n-tier application requires a table in an Amazon RDS MySQL DB instance to be dropped and repopulated at each deployment. This process can take several minutes and the web tier cannot come online until the process is complete. Currently, the web tier is configured in an Amazon EC2 Auto Scaling group, with instances being terminated and replaced at each deployment. The MySQL table

is populated by running a SQL query through an AWS CodeBuild job.

What should be done to ensure that the web tier does not come online before the database is completely configured?

AUse Amazon Aurora as a drop-in replacement for RDS MySQL. Use snapshots to populate the table with the correct data.

BModify the launch configuration of the Auto Scaling group to pause user data execution for 600 seconds, allowing the table to be populated.

CUse AWS Step Functions to monitor and maintain the state of data population. Mark the database in service before continuing with the deployment.

DUse an EC2 Auto Scaling lifecycle hook to pause the configuration of the web tier until the table is populated.

Correct Answer: D

Question No. 5

A company used AWS CloudFormation to deploy a three-tier web application that stores data in an Amazon RDS MySOL Multi-AZ DB instance. A DevOps Engineer must upgrade the RDS instance to the latest major version of MySQL while incurring minimal downtime. How should the Engineer upgrade the instance while minimizing downtime?

AUpdate the EngineVersion property of the AWS::RDS::DBInstance resource type in the CloudFormation template to the latest desired version. Launch a second stack and make the new RDS instance a read replica.

BUpdate the DBEngineVersion property of the AWS:: RDS::DBInstance resource type in the CloudFormation template to the latest desired version. Perform an Update Stack operation. Create a new RDS Read Replicas resource with the same properties as the instance to be upgraded. Perform a second Update Stack operation.

CUpdate the DBEngineVersion property of the AWS::RDS::DBInstance resource type in the CloudFormation template to the latest desired version. Create a new RDS Read Replicas resource with the same properties as the instance to be upgraded. Perform an Update Stack operation.
