Free Amazon DOP-C02 Exam Questions

Question 1

A company’s EC2 fleet must maintain up-to-date security patches and compliance reporting. Which solution meets these requirements?

A : Use Systems Manager Patch Manager with AWS Config compliance rules and automation documents.

B : SSH into each instance manually.

C : Rebuild instances in Auto Scaling groups with latest AMIs.

D : Use CloudFormation redeployment for every patch.

Answer: A

Question 2

A company is developing a web application that runs on Amazon EC2 Linux instances. The application requires monitoring of custom performance metrics. The company must collect metrics for API response times and database query latency across multiple instances. Which solution will generate the custom metrics with the LEAST operational overhead?

A : Install the Amazon CloudWatch agent on the instances. Configure the agent to collect the custom metrics. Instrument the application to send the metrics to the agent.

B : Use Amazon Managed Service for Prometheus to scrape the custom metrics from the application. Use the Amazon CloudWatch agent to forward the metrics to CloudWatch.

C : Create a custom AWS Lambda function that polls the application endpoints and database at regular intervals. Program the Lambda function to calculate the custom metrics and to send the metrics to Amazon CloudWatch by using PutMetricData API calls.

D : Implement custom logging in the application code to record the custom metrics. Use Amazon CloudWatch Logs Insights to extract and analyze the metrics.

Answer: A

Question 3

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

A : Create a global table replica of the DynamoDB table in a second Region.

B : Create a global secondary index for the DynamoDB table.

C : Create copies of the REST API and the Lambda functions in a second Region.

D : Create health checks in Amazon Route 53. Create DNS records that include a failover routing policy.

E : Create health checks in Amazon Route 53. Create DNS records that include a latency routing policy.

F : Create DNS records in Amazon Route 53 that include a multivalue answer routing policy.

Answer: A,C,E

Question 4

You are developing a mobile news homepage that curates several news sources to a single page. The app is mainly composed of several Lambda functions configured as a deployment group on AWS CodeDeploy. For each new app version, you need to test all APIs before fully deploying it to production. The APIs are using a set of AWS Lambda validation scripts. You want the ability to check the APIs during deployments and be notified for any API errors as well as automatic rollback if the validation fails.

Which combination of the options below can help you implement a solution for this scenario? (Select THREE)

A : fine your Lambda validation scripts on the AppSpec lifecycle hook during deployment to run the validation using test traffic and trigger a rollback if checks fail.

B : ve Lambda send results to AWS CloudWatch Alarms directly and trigger a rollback when 5xx reply errors are received during deployment.

C : a step on AWS CodeDeploy to trigger your Lambda validation scripts after deployment and invoke them after deployment to validate your new app version.

D : nfigure your Lambda validation scripts to run during deployment and configure a CloudWatch Alarm that will trigger a rollback when the function validation fails.

E : ve CodeDeploy run the AWS Lambda validations after the deployment so you can test with production traffic. When errors are found, have another trigger to rollback the deployment.

F : ociate an AWS CloudWatch Alarm to your deployment group that can send a notification to an AWS SNS topic when threshold for 5xx is reached on CloudWatch.

Answer: A,D

Question 5

A DevOps engineer needs to configure an AWS CodePipeline pipeline that publishes container images to an Amazon ECR repository. The pipeline must wait for the previous run to finish and must run when new Git tags are pushed to a Git repository connected to AWS CodeConnections. An existing deployment pipeline must run in response to new container image publications. Which solution will meet these requirements?

A : Configure a CodePipeline V2 type pipeline that uses QUEUED mode. Add a trigger filter to the pipeline definition that includes all tags. Configure an EventBridge rule that matches container image pushes to start the existing deployment pipeline.

B : Configure a CodePipeline V2 type pipeline that uses SUPERSEDED mode. Add a trigger filter to the pipeline definition that includes all branches. Configure an EventBridge rule that matches container image pushes to start the existing deployment pipeline.

C : Configure a CodePipeline V1 type pipeline that uses SUPERSEDED mode. Add a trigger filter to the pipeline definition that includes all tags. Add a stage at the end of the pipeline to invoke the existing deployment pipeline.

D : Configure a CodePipeline V1 type pipeline that uses QUEUED mode. Add a trigger filter to the pipeline definition that includes all branches. Add a stage at the end of the pipeline to invoke the existing deployment pipeline.
