Free Amazon DOP-C02 Exam Questions

Question 1

A software development company is using AWS CodeCommit, AWS CodeBuild, AWS CodeDeploy, and AWS CodePipeline for its CI/CD process. To further improve their systems, they need to implement a solution that automatically detects and reacts to changes in the state of their deployments in AWS CodeDeploy. Any changes must be rolled back automatically if the deployment process fails, and a notification must be sent to the DevOps Team's Slack channel for easy monitoring.

Which of the following is the MOST suitable configuration that you should implement to satisfy this requirement?

A : t up a CloudWatch Events rule to monitor AWS CodeDeploy operations with a Lambda function as a target. Configure the rule to send out a message to the DevOps Team's Slack Channel in the event that the deployment fails. Configure AWS CodeDeploy to use the Roll back when a deployment fails setting.

B : nitor the API calls in the CodeDeploy project using AWS CloudTrail. Send a message to the DevOps Team's Slack Channel when the PutLifecycleEventHookExecutionStatus API call has been detected. Rollback the changes by using the AWS CLI.

C : t up a CloudWatch Alarm that tracks the CloudWatch metrics of the CodeDeploy project. Configure the CloudWatch Alarm to automatically send out a message to the DevOps Team's Slack Channel when the deployment fails. Configure AWS CodeDeploy to use the Roll back when alarm thresholds are met setting.

D : nfigure a CodeDeploy agent to send notification to the DevOps Team's Slack Channel when the deployment fails. Configure AWS CodeDeploy to automatically roll back whenever the deployment is not successful.

Answer: A

Question 2

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 3

A DevOps engineer is creating a CI/CD pipeline to build container images. The engineer needs to store container images in Amazon Elastic Container Registry (Amazon ECR) and scan the images for common vulnerabilities. The CI/CD pipeline must be resilient to outages in upstream source container image repositories. Which solution will meet these requirements?

A : Create an ECR private repository in the private registry to store the container images and scan images when images are pushed to the repository. Configure a replication rule in the private registry to replicate images from upstream repositories.

B : Create an ECR public repository in the public registry to cache images from upstream source repositories. Create an ECR private repository to store images. Configure the private repository to scan images when images are pushed to the repository.

C : Create an ECR public repository in the public registry. Configure a pull through cache rule for the repository. Create an ECR private repository to store images. Configure the ECR private registry to perform basic scanning.

D : Create an ECR private repository in the private registry to store the container images. Enable basic scanning for the private registry, and create a pull through cache rule.

Answer: C

Question 4

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 5

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
