Free Amazon DOP-C02 Exam Questions

Question 1

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 2

A DevOps engineer has been tasked to implement a reliable solution to maintain all of their Windows and Linux servers both in AWS and in on-premises data center. There should be a system that allows them to easily update the operating systems of their servers and apply the core application patches with minimum management overhead. The patches must be consistent across all levels in order to meet the company’s security compliance.

Which of the following is the MOST suitable solution that you should implement?

A : Store the login credentials of each Linux and Windows servers on the AWS Systems Manager Parameter Store. Use Systems Manager Resource Groups to set up one group for your Linux servers and another one for your Windows servers. Remotely login, run, and deploy the patch updates to all of your servers using the credentials stored in the Systems Manager Parameter Store and through the use of the Systems Manager Run Command.

B : velop a custom python script to install the latest OS patches on the Linux servers. Set up a scheduled job to automatically run this script using the cron scheduler on Linux servers. Enable Windows Update in order to automatically patch Windows servers or set up a scheduled task using Windows Task Scheduler to periodically run the python script.

C : Configure and install the AWS OpsWorks agent on all of your EC2 instances in your VPC and your on-premises servers. Set up an OpsWorks stack with separate layers for each OS then fetch a recipe from the Chef supermarket site (supermarket.chef.io) to automate the execution of the patch commands for each layer during maintenance windows.

D : nfigure and install AWS Systems Manager agent on all of the EC2 instances in your VPC as well as your physical servers on-premises. Use the Systems Manager Patch Manager service and specify the required Systems Manager Resource Groups for your hybrid architecture. Utilize a preconfigured patch baseline and then run scheduled patch updates during maintenance windows.

Answer: D

Question 3

A company wants to migrate its content sharing web application hosted on Amazon EC2 to a serverless architecture. The company currently deploys changes to its application by creating a new Auto Scaling group of EC2 instances and a new Elastic Load Balancer, and then shifting the traffic away using an Amazon Route 53 weighted routing policy.

For its new serverless application, the company is planning to use Amazon API Gateway and AWS Lambda. The company will need to update its deployment processes to work with the new application. It will also need to retain the ability to test new features on a small number of users before rolling the features out to the entire user base.

Which deployment strategy will meet these requirements?

A : AWS CDK to deploy API Gateway and Lambda functions. When code needs to be changed, update the AWS CloudFormation stack and deploy the new version of the APIs and Lambda functions. Use a Route 53 failover routing policy for the canary release strategy.

B : AWS CloudFormation to deploy API Gateway and Lambda functions using Lambda function versions. When code needs to be changed, update the CloudFormation stack with the new Lambda code and update the API versions using a canary release strategy. Promote the new version when testing is complete.

C : AWS Elastic Beanstalk to deploy API Gateway and Lambda functions. When code needs to be changed, deploy a new version of the API and Lambda functions. Shift traffic gradually using an Elastic Beanstalk blue/green deployment.

D : AWS OpsWorks to deploy API Gateway in the service layer and Lambda functions in a custom layer. When code needs to be changed, use OpsWorks to perform a blue/green deployment and shift traffic gradually

Answer: B

Question 4

A SaaS company uses ECS (Fargate) behind an ALB and CodePipeline + CodeDeploy for blue/green deployments. They need automatic, incremental traffic shifting over time with no downtime. Which solution will meet these requirements?

A : Use TimeBasedLinear in appspec.yaml with defined percentage and interval.

B : Use AllAtOnce deployment configuration.

C : Use TimeBasedCanary.

D : Configure weighted routing on ALB manually.

Answer: A

Question 5

A leading e-commerce company has a payment portal that handles the payment and refund transactions of its online platform. The portal is hosted in an Auto Scaling group of On-Demand EC2 instances across three multiple Availability Zones in the US West (N. California) region. There is a new requirement to improve the system monitoring of the application as well to track the number of payment and refund transactions being done every minute. The DevOps team should also be notified if this metric breached the specified threshold.

Which of the following options provides the MOST cost-effective and automated solution that will satisfy the above requirement?

A : nfigure the instances to push the number of payments and refund transactions to CloudWatch as a custom metric. Set up a CloudWatch alarm to notify the DevOps team using SNS when the threshold is breached. View statistical graphs of your published metrics with the AWS Management Console.

B : t up an ELK stack that is composed of Elasticsearch, Logstash, and Kibana for log processing. Store the payments and refund transactions in each instance and configure Logstash to send the logs to Amazon ES. Set up a Kibana dashboard to view the data and the metric graphs.

C : nfigure the instances to push the entire log of each payments and refund transactions to CloudWatch Events as a custom metric. Set up a CloudWatch alarm to notify the DevOps team using SNS when the threshold is breached. View statistical graphs of your published metrics with the AWS Management Console.

D : nfigure the instances to push the number of payments and refund transactions to Amazon CloudWatch Logs as a custom metric. Develop a custom monitoring application using a Python-based Flask web application to view the metrics and host it in an Amazon EC2 instance.

Answer: A
