Free Amazon DOP-C02 Exam Questions

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 : ploy 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 : 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 : 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 : 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 DevOps engineer must implement a solution that immediately terminates Amazon EC2 instances in Auto Scaling groups when cryptocurrency mining activity is detected. Which solution will meet these requirements with the LEAST development effort?

A : Configure Amazon Route 53 query logs # CloudWatch # Lambda every 5 mins to detect mining-related domains and terminate EC2 instances.

B : Configure VPC Flow Logs # S3 # Lambda every 5 mins # Athena query # terminate EC2 instances.

C : Enable Amazon GuardDuty. Monitor EC2 findings. Create an EventBridge rule triggered by GuardDuty. Invoke a Lambda function that terminates the affected EC2 instances.

D : Enable AWS Security Hub. Monitor EC2 findings. Create an EventBridge rule triggered by SecurityHub. Invoke Lambda to terminate EC2 instances.

Answer: C

Question 3

A government agency is planning to launch a distributed system in AWS that processes thousands of transactions every day. The agency purchased a proprietary software with 100 licenses, which can be used by a maximum of 100 application servers. A DevOps Engineer needs to set up an automated solution that dynamically allocates the software licenses to the application servers. The Engineer also needs to provide a way to see the list of available licenses that are not in use.

Which of the following options below is the MOST suitable way to accomplish this task?

A : epare a CloudFormation template that uses an Auto Scaling group to launch the EC2 instances with an associated lifecycle hook for Instance Terminate. Store the 100 license codes to AWS Certificate Manager (ACM). Pull an available license from ACM using the User Data script of the instance upon launch. Use the lifecycle hook to update the license mapping after the instance is terminated.

B : epare a CloudFormation template that uses an Auto Scaling group to launch the EC2 instances with an associated lifecycle hook for Instance Terminate. Store the 100 license codes to a public S3 bucket. Pull an available license from the bucket using the User Data script of the instance upon launch. Use the lifecycle hook to update the license mapping after the instance is terminated.

C : epare a CloudFormation template that uses an Auto Scaling group to launch the EC2 instances with an associated lifecycle hook for Instance Terminate. Store the 100 license codes to a DynamoDB table. Pull an available license from the DynamoDB table using the User Data script of the instance upon launch. Use the lifecycle hook to update the license mapping after the instance is terminated.

D : epare a CloudFormation template that uses an Auto Scaling group to launch the EC2 instances. Store the 100 license codes to AWS Systems Manager Parameter Store. Pull an available license from the Systems manager using the instance metadata script of the instance upon launch. Configure the metadata script to update the license mapping after the instance is terminated.

Answer: C

Question 4

A company deploys an application to Amazon EC2 instances. The application runs Amazon Linux 2 and uses AWS CodeDeploy. The application has the following file structure for its code repository:

The appspec.yml file has the following contents in the files section:

What will the result be for the deployment of the config.txt file?

A : The config.txt file will be deployed to only /var/www/html/config/config.txt.

B : The config.txt file will be deployed to /usr/local/src/config.txt and to /var/www/html/config/config.txt.

C : The config.txt file will be deployed to only /usr/local/src/config.txt.

D : The config.txt file will be deployed to /usr/local/src/config.txt and to /var/www/html/application/web/config.txt.

Answer: C

Question 5

A company is re-architecting its monolithic system to a serverless application in AWS to save on cost. The deployment of the succeeding new version of the application must be initially rolled out to a small number of users first for testing before the full release. If the post-hook tests fail, there should be an easy way to roll back the deployment. The DevOps Engineer was assigned to design an efficient deployment setup that mitigates any unnecessary outage that impacts their production environment.

As a DevOps Engineer, how should you satisfy this requirement? (Select TWO.)

A : Create a new record in Route 53 with a Failover routing policy. Configure the primary record to route 20% of incoming traffic to the new version and set the secondary record to route the rest of the traffic to the current version. Once the new version stabilizes, update the primary record to route all traffic to the new version.

B : Launch an Application Load Balancer with an Amazon API Gateway private integration. Attach a single target group to the load balancer and select the 'Canary' routing option which will automatically route incoming traffic to the new version.

C : Launch a Network Load Balancer with an Amazon API Gateway private integration. Attach two target groups to the load balancer. Configure the first target group with the current version and the second target group with the new version. Configure the load balancer to route 20% of the incoming traffic to the new version and once it becomes stable, detach the first target group from the load balancer.

D : t up a canary deployment in Amazon API Gateway that routes 20% of the incoming traffic to the canary release. Promote the canary release to production once the initial tests have passed.

E : t up one AWS Lambda Function Alias that points to both the current and new versions. Route 20% of incoming traffic to the new version and once it is considered stable, update the alias to route all traffic to the new version.
