AWS Certified DevOps Engineer - Professional Questions and Answers

Question 1

A DevOps engineer is researching the least expensive way to implement an image batch processing cluster on AWS. The application cannot run in Docker containers and must run on Amazon EC2. The batch job stores checkpoint data on an NFS volume and can tolerate interruptions. Configuring the cluster software from a generic EC2 Linux image takes 30 minutes.

What is the MOST cost-effective solution?

Options:

A.

Use Amazon EFS (or checkpoint data. To complete the job, use an EC2 Auto Scaling group and an On-Demand pricing model to provision EC2 instances temporally.

B.

Use GlusterFS on EC2 instances for checkpoint data. To run the batch job configure EC2 instances manually When the job completes shut down the instances manually.

C.

Use Amazon EFS for checkpoint data Use EC2 Fleet to launch EC2 Spot Instances and utilize user data to configure the EC2 Linux instance on startup.

D.

Use Amazon EFS for checkpoint data Use EC2 Fleet to launch EC2 Spot Instances Create a custom AMI for the cluster and use the latest AMI when creating instances.

Question 2

A company uses an organization in AWS Organizations to manage multiple AWS accounts. The company has enabled all features for the organization. The member accounts under one OU contain S3 buckets that store sensitive data.

A DevOps engineer wants to ensure that only IAM principals from within the organization can access the S3 buckets in the OU.

Which solution will meet this requirement?

Options:

A.

Create an SCP in the management account of the organization to restrict Amazon S3 actions by using the aws:PrincipalAccount condition. Apply the SCP to the OU.

B.

Create an IAM permissions boundary in the management account of the organization to restrict access to Amazon S3 actions by using the aws:PrincipalOrgID condition.

C.

Configure AWS Resource Access Manager (AWS RAM) to restrict access to S3 buckets in the OU so the S3 buckets cannot be shared outside the organization.

D.

Create a resource control policy (RCP) in the management account of the organization to restrict Amazon S3 actions by using the aws:PrincipalOrgID condition. Apply the RCP to the OU.

Question 3

A company manages a web application that runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The EC2 instances run in an Auto Scaling group across multiple Availability Zones. The application uses an Amazon RDS for MySQL DB instance to store the data. The company has configured Amazon Route 53 with an alias record that points to the ALB.

A new company guideline requires a geographically isolated disaster recovery (DR > site with an RTO of 4 hours and an RPO of 15 minutes.

Which DR strategy will meet these requirements with the LEAST change to the application stack?

Options:

A.

Launch a replica environment of everything except Amazon RDS in a different Availability Zone Create an RDS read replica in the new Availability Zone: and configure the new stack to point to the local RDS DB instance. Add the new stack to the Route 53 record set by using a hearth check to configure a failover routing policy.

B.

Launch a replica environment of everything except Amazon RDS in a different AWS. Region Create an RDS read replica in the new Region and configure the new stack to point to the local RDS DB instance. Add the new stack to the Route 53 record set by using a health check to configure a latency routing policy.

C.

Launch a replica environment of everything except Amazon RDS ma different AWS Region. In the event of an outage copy and restore the latest RDS snapshot from the primary. Region to the DR Region Adjust the Route 53 record set to point to the ALB in the DR Region.

D.

Launch a replica environment of everything except Amazon RDS in a different AWS Region. Create an RDS read replica in the new Region and configure the new environment to point to the local RDS DB instance. Add the new stack to the Route 53 record set by using a health check to configure a failover routing policy. In the event of an outage promote the read replica to primary.
