Free Amazon DOP-C02 Exam Questions

Question 1

An AWS CodePipeline pipeline has implemented a code release process. The pipeline is integrated with AWS CodeDeploy to deploy versions of an application to multiple Amazon EC2 instances for each CodePipeline stage.

During a recent deployment, the pipeline failed due to a CodeDeploy issue. The DevOps team wants to improve monitoring and notifications during deployment to decrease resolution times.

What should the DevOps engineer do to create notifications when issues are discovered?

A : plement Amazon CloudWatch Logs for CodePipeline and CodeDeploy, create an AWS Config rule to evaluate code deployment issues, and create an Amazon Simple Notification Service (Amazon SNS) topic to notify stakeholders of deployment issues.

B : plement Amazon EventBridge for CodePipeline and CodeDeploy, create an AWS Lambda function to evaluate code deployment issues, and create an Amazon Simple Notification Service (Amazon SNS) topic to notify stakeholders of deployment issues.

C : plement AWS CloudTrail to record CodePipeline and CodeDeploy API call information, create an AWS Lambda function to evaluate code deployment issues, and create an Amazon Simple Notification Service (Amazon SNS) topic to notify stakeholders of deployment issues.

D : plement Amazon EventBridge for CodePipeline and CodeDeploy, create an Amazon Inspector assessment target to evaluate code deployment issues, and create an Amazon Simple Notification Service (Amazon SNS) topic to notify stakeholders of deployment issues.

Answer: B

Question 2

A company uses Amazon Redshift as its data warehouse solution. The company wants to create a dashboard to view changes to the Redshift users and the queries the users perform. Which combination of steps will meet this requirement? (Select TWO.)

A : Create an Amazon CloudWatch log group. Create an AWS CloudTrail trail that writes to the CloudWatch log group.

B : Create a new Amazon S3 bucket. Configure default audit logging on the Redshift cluster. Configure the S3 bucket as the target.

C : Configure the Redshift cluster database audit logging to include user activity logs. Configure Amazon CloudWatch as the target.

D : Create an Amazon CloudWatch dashboard that has a log widget. Configure the widget to display user details from the Redshift logs.

E : Create an AWS Lambda function that uses Amazon Athena to query the Redshift logs. Create an Amazon CloudWatch dashboard that has a custom widget type that uses the Lambda function.

Answer: B,D

Question 3

A DevOps engineer is building the infrastructure for an application. The application needs to run on an Amazon Elastic Kubernetes Service (Amazon EKS) cluster that includes Amazon EC2 instances. The EC2 instances need to use an Amazon Elastic File System (Amazon EFS) file system as a storage backend. The Amazon EFS Container Storage Interface (CSI) driver is installed on the EKS cluster.

When the DevOps engineer starts the application, the EC2 instances do not mount the EFS file system.

Which solutions will fix the problem? (Choose three.)

A : Switch the EKS nodes from Amazon EC2 to AWS Fargate.

B : Add an inbound rule to the EFS file system’s security group to allow NFS traffic from the EKS cluster.

C : Create an IAM role that allows the Amazon EFS CSI driver to interact with the file system

D : Set up AWS DataSync to configure file transfer between the EFS file system and the EKS nodes.

E : Create a mount target for the EFS file system in the subnet of the EKS nodes.

F : Disable encryption or the EFS file system.

Answer: B,C,F

Question 4

A telecommunications company has a web portal that requires a cross-region failover. The portal stores its data in an Amazon Aurora database in the primary region (us-west-1) and the Parallel Query feature is also enabled in the database to optimize some of the I/O and computation involved in processing data-intensive queries. The portal uses Route 53 to direct customer traffic to the active region.

Which among the options below should be taken to MINIMIZE downtime of the portal in the event that the primary database fails?

A : eate a CloudWatch Events rule to periodically invoke a Lambda function that checks the health of the primary Amazon Aurora database every hour. Configure the Lambda function to promote the read replica as the primary if a failure was detected. Update the Route 53 record to redirect traffic from the primary to the secondary region.

B : nfigure the Route 53 record to balance traffic between both regions equally using the Failover routing policy. Enable the Aurora multi-master option and set up a Route 53 health check to analyze the health of the databases. Set the Route 53 record to automatically direct all traffic to the secondary region when a primary database fails.

C : unch a read replica of the primary database to the second region. Set up Amazon RDS Event Notification to publish status updates to an SNS topic. Create a Lambda function subscribed to the topic to monitor database health. Configure the Lambda function to promote the read replica as the primary in the event of a failure. Update the Route 53 record to redirect traffic from the primary region to the secondary region.

D : t up CloudWatch to monitor the status of the Amazon Aurora database. Create a CloudWatch Events rule to send a Slack message to the SysOps Team using Amazon SNS in the event of a database outage. Instruct the SysOps team to redirect traffic to an S3 static website that displays a downtime message. Manually promote the read replica as the primary instance and verify the portal's status. Redirect traffic from the S3 website to the secondary region.

Answer: C

Question 5

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
