Free Amazon DOP-C02 Exam Questions

Question 1

A company has several AWS accounts. An Amazon Connect instance runs in each account. The company uses an Amazon EventBridge default event bus in each account for event handling. A DevOps team needs to receive all the Amazon Connect events in a single DevOps account. Which solution meets these requirements?

A : Update the resource-based policy of the default event bus in each account to allow the DevOps account to replay events. Configure an EventBridge rule in the DevOps account that matches Amazon Connect events and has a target of the default event bus in the other accounts.

B : Update the resource-based policy of the default event bus in each account to allow the DevOps account to receive events. Configure an EventBridge rule in the DevOps account that matches Amazon Connect events and has a target of the default event bus in the other accounts.

C : Update the resource-based policy of the default event bus in the DevOps account. Update the policy to allow events to be received from the accounts. Configure an EventBridge rule in each account that matches Amazon Connect events and has a target of the DevOps account's default event bus

D : Update the resource-based policy of the default event bus in the DevOps account. Update the policy to allow events to be replayed by the accounts. Configure an EventBridge rule in each account that matches Amazon Connect events and has a target of the DevOps account's default event bus.

Answer: C

Question 2

A DevOps engineer is supporting early-stage development for a developer platform running on Amazon EKS. Recently, the platform has experienced an increased rate of container restart failures. The DevOps engineer wants diagnostic information to isolate and resolve issues. Which solution will meet this requirement?

A : Configure CloudWatch dashboards using default EKS service metrics.

B : Configure AWS CloudTrail for the EKS cluster.

C : Configure CloudTrail Insights for the EKS cluster.

D : Configure Amazon CloudWatch Container Insights for the EKS cluster by enabling the CloudWatch Observability add-on.

Answer: D

Question 3

A company runs an Amazon EKS cluster and must implement comprehensive logging for the control plane and nodes. The company must analyze API requests and monitor container performance. Which solution will meet these requirements with the LEAST operational overhead?

A : Enable AWS CloudTrail for control plane logging and deploy Logstash on nodes.

B : Enable control plane logging to CloudWatch and use CloudWatch Container Insights for node and pod metrics.

C : Enable API server logging to S3 and deploy Kubernetes Event Exporter to nodes.

D : Use AWS Distro for OpenTelemetry and stream logs to Amazon Redshift.

Answer: B

Question 4

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 5

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
