Question 1

A company requires an RPO of 2 hours and an RTO of 10 minutes for its data and application at all times An application uses a MySQL database and Amazon EC2 web servers. The development learn needs a strategy for failover and disaster recovery

Which combination of deployment strategies will meet these requirements? {Select TWO)

ACreate an Amazon Aurora cluster in one Availability Zone across multiple Regions as the data store Use Aurora's automatic recovery capabilities in the event of a discluster.

BCreate an Amazon Aurora global database m two Regions as the data store In the event of a failure, promote the secondary Region as the master for the application

CCreate an Amazon Aurora multi-master cluster across multiple Regions as the data store Use an Network Load Balancer to balance the database traffic in different Regions.

DSet up the application in two Regions and use Amazon Route 53 failover-based routing that points to the Application Load Balancers in both Regions Use health checks to determine the availability in a given Region. Use Auto Scaling groups in each Region to adjust capacity based on demand

ESet up the application m two Regions and use a multi-Region Auto Scaling group behind Application Load Balancers to manage the capacity based on demand in the event of a disaster, adjust the Auto Scaling group's desired instance count to increase baseline capacity in the failover Region.

Answer : B, E

Question 2

A DevOps engineer is tasked with moving a mission-critical business application running in Go to AWS. The development team running this application is understaffed and requires a solution that allows the team to focus on application development. They also want to enable blue/green deployments and perform A/B testing.

Which solution will meet these requirements?

ADeploy the application on an Amazon EC2 instance and create an AMI of this instance. Use this AMI to create an automatic scaling launch configuration that is used in an Auto Scaling group. Use an Elastic Load Balancer to distribute traffic. When changes are made to the application, a new AMI is created and replaces the launch configuration.

BUse 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.

CUse AWS CodePipeline with AWS CodeDeploy to deploy the application to a fleet of Amazon EC2 instances. Use an Elastic Load Balancer to distribute the traffic to the EC2 instances. When making changes to the application, upload a new version to CodePipeline and let it deploy the new version.

DUse AWS Elastic Beanstalk to host the application. Store a zipped version of the application in Amazon S3, and use that location to deploy new versions of the application using Elastic Beanstalk to manage the deployment options.

Answer : D

Question 3

A company wants to use AWS Systems Manager documents to bootstrap physical laptops for developers. The bootstrap code is stored in GitHub. A DevOps engineer has already created a Systems Manager activation, installed the Systems Manager agent with the registration code, and installed an activation ID on all the laptops.

Which set of steps should be taken next?

AConfigure the Systems Manager document to use the AWS-RunShellScript command to copy the files from GitHub to Amazon S3, then use the aws-downloadContent plugin with a source Type of S3.

BConfigure the Systems Manager document to use the aws-configurePackage plugin with an install action and point to the Git repository.

CConfigure the Systems Manager document to use the aws-downloadContent plugin with a sourceType of GitHub and sourcelnfo with the repository details.

DConfigure the Systems Manager document to use the aws:softwarelnventory plugin and run the script from the Git repository.

Answer : D

Question 4

A company needs to implement a robust CI/CD pipeline to automate the deployment of an application in AWS. The pipeline must support continuous integration, continuous delivery, and automatic rollback upon deployment failure. The entire CI/CD pipeline must be capable of being re-provisioned in alternate AWS accounts or Regions within minutes. A DevOps engineer has already created an AWS CodeCommit repository to store the source code.

Which combination of actions should be taken when building this pipeline to meet these requirements? (Select THREE.)

AConfigure an AWS CodePipehne pipeline with a build stage using AWS CodeBuild.

BCopy the build artifact from CodeCommit to Amazon S3.

CCreate an Auto Scaling group of Amazon EC2 instances behind an Application Load Balancer (ALB) and set the ALB as the deployment target in AWS CodePipeline.

DCreate an AWS Elastic Beanstalk environment as the deployment target in AWS CodePipeline.

EImplement an Amazon SQS queue to decouple the pipeline components.

FProvision all resources using AWS CloudFormation.

Answer : A, B, D

Question 5

A development team wants to deploy an application using AWS CloudFormation stacks, but the developer IAM role does not currently have the required permissions to provision the resources specified in the CloudFormation template. A DevOps engineer is tasked with allowing developers to deploy the stacks while following the principal of least privilege.

Which solution will meet these requirements?

ACreate an IAM policy that allows developers to provision the required resources. Attach the policy to the developer role.

BCreate an IAM policy that allows full access to CloudFormation. Attach the policy to the developer role.

CCreate a new IAM role with the required permissions to use as a CloudFormation service role. Grant the developer role a cloudformation:* action.

DCreate a new IAM role with the required permissions to use as a CloudFormation service role. Grant the developer role the iam:PassRole permission.

Answer : C

Question 6

An application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). A DevOps engineer is using AWS CodeDeploy to release a new version. The deployment fails during the AllowTraffic lifecycle event, but a cause for the failure is not indicated in the deployment logs.

What would cause this?

AThe appspec.yml file contains an invalid script to execute in the AllowTraffic lifecycle hook.

BThe user who initiated the deployment does not have the necessary permissions to interact with the ALB

CThe health checks specified for the ALB target group are misconfigured.

DThe CodeDeploy agent was not installed in the EC2 instances that are part of the ALB target group.

Answer : C

Question 7

A company has thousands of Amazon EC2 instances as well as hundreds of virtual machines on-premises. Developers routinely sign in to the console for on-premises systems to perform troubleshooting. The developers want to sign in to AWS instances to run performance tools, but are unable to due to the lack of a central console logging system. A DevOps engineer wants to ensure that console access is logged on all systems.

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

AAttach a role to all AWS instances that contains the appropriate permissions. Create an AWS Systems Manager managed-instance activation. Install and configure Systems Manager Agent on on-premises machines.

BEnable AWS Systems Manager Session Manager logging to an Amazon S3 bucket. Direct developers to connect to the systems with Session Manager only.

CEnable AWS Systems Manager Session Manager logging to AWS CloudTrail. Direct developers to continue normal sign-in procedures for on-premises. Use Session Manager for AWS instances.

DInstall and configure an Amazon CloudWatch Logs agent on all systems. Create an AWS Systems Manager managed-instance activation.

ESet up a Site-to-Site VPN connection between the on-premises and AWS networks. Set up a bastion instance to allow developers to sign in to the AWS instances.
