AWS Certified DevOps Engineer - Professional Questions and Answers

Question 1

A company uses an organization in AWS Organizations that has all features enabled to manage multiple AWS accounts. The company has enabled AWS Config in all accounts. The company requires developers to create AWS CloudFormation stacks in a new AWS account to test features for a new application that the developers are building.

The company wants to ensure that the developers can use only approved Amazon EC2 instance types for the application.

Which solution will meet these requirements?

Options:

A.

Create an AWS Lambda function that returns SUCCESS when the EC2 instance type property matches a value from a list of approved instance types. Activate a CloudFormation Guard Hook in the new AWS account to run the Lambda function.

B.

Create an AWS Config rule that uses the desired-instance-type rule in the new AWS account. Provide the list of approved instance types in the rule configuration. Create a remediation for the AWS Config rule that uses the AWS-StopEC2Instance remediation action.

C.

Create an SCP that includes a Deny effect for ec2:RunInstances when the ec2:InstanceType property does not match a value from a list of approved instance types. Attach the SCP to the root of the organization.

A company uses an AWS CodeArtifact repository to store Python packages that the company developed internally. A DevOps engineer needs to use AWS CodeDeploy to deploy an application to an Amazon EC2 instance. The application uses a Python package that is stored in the CodeArtifact repository. A BeforeInstall lifecycle event hook will install the package.

The DevOps engineer needs to grant the EC2 instance access to the CodeArtifact repository.

Which solution will meet this requirement?

Options:

A.

Create a service-linked role for CodeArtifact. Associate the role with the EC2 instance. Use the aws codeartifact get-authorization-token CLI command on the instance.

B.

Configure a resource-based policy for the CodeArtifact repository that allows the Read-FromRepository action for the EC2 instance principal.

C.

Configure ACLs on the CodeArtifact repository to allow the EC2 instance to access the Python package.

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

Options:

A.

Change the Auto Scaling configuration to replace the instances when they fail the load balancer ' s health checks.

B.

Change the target group health check HealthChecklntervalSeconds parameter to reduce the interval between health checks.

C.

Change the target group health checks from HTTP to TCP to check if the port where the application is listening is reachable.

D.

Enable the available memory consumption metric within the Amazon CloudWatch dashboard for the entire Auto Scaling group Create an alarm when the memory utilization is high Associate an Amazon SNS topic to the alarm to receive notifications when the alarm goes off

E.

Use the Amazon CloudWatch agent to collect the memory utilization of the EC2 instances in the Auto Scaling group Create an alarm when the memory utilization is high and associate an Amazon SNS topic to receive a notification.
