Free Amazon DOP-C02 Exam Questions

Question 1

A company's developers use Amazon EC2 instances as remote workstations. The company is concerned that users can create or modify EC2 security groups to allow unrestricted inbound access.

A DevOps engineer needs to develop a solution to detect when users create unrestricted security group rules. The solution must detect changes to security group rules in near real time, remove unrestricted rules, and send email notifications to the security team. The DevOps engineer has created an AWS Lambda function that checks for security group ID from input, removes rules that grant unrestricted access, and sends notifications through Amazon Simple Notification Service (Amazon SNS).

What should the DevOps engineer do next to meet the requirements?

A : nfigure the Lambda function to be invoked by the SNS topic. Create an AWS CloudTrail subscription for the SNS topic. Configure a subscription filter for security group modification events.

B : eate an Amazon EventBridge scheduled rule to invoke the Lambda function. Define a schedule pattern that runs the Lambda function every hour.

C : eate an Amazon EventBridge event rule that has the default event bus as the source. Define the rule’s event pattern to match EC2 security group creation and modification events. Configure the rule to invoke the Lambda function.

D : eate an Amazon EventBridge custom event bus that subscribes to events from all AWS services. Configure the Lambda function to be invoked by the custom event bus.

Answer: C

Question 2

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 3

A company is building a new pipeline by using AWS CodePipeline and AWS CodeBuild in a build account. The pipeline consists of two stages. The first stage is a CodeBuild job to build and package an AWS Lambda function. The second stage consists of deployment actions that operate on two different AWS accounts: a development environment account and a production environment account. The deployment stages use the AWS CloudFormation action that CodePipeline invokes to deploy the infrastructure that the Lambda function requires.

A DevOps engineer creates the CodePipeline pipeline and configures the pipeline to encrypt build artifacts by using the AWS Key Management Service (AWS KMS) AWS managed key for Amazon S3 (the aws/s3 key). The artifacts are stored in an S3 bucket. When the pipeline runs, the CloudFormation actions fail with an access denied error.

Which combination of actions must the DevOps engineer perform to resolve this error? (Choose two.)

A : eate an S3 bucket in each AWS account for the artifacts. Allow the pipeline to write to the S3 buckets. Create a CodePipeline S3 action to copy the artifacts to the S3 bucket in each AWS account. Update the CloudFormation actions to reference the artifacts S3 bucket in the production account.

B : eate a customer managed KMS key. Configure the KMS key policy to allow the IAM roles used by the CloudFormation action to perform decrypt operations. Modify the pipeline to use the customer managed KMS key to encrypt artifacts.

C : eate an AWS managed KMS key. Configure the KMS key policy to allow the development account and the production account to perform decrypt operations. Modify the pipeline to use the KMS key to encrypt artifacts.

D : the development account and in the production account, create an IAM role for CodePipeline. Configure the roles with permissions to perform CloudFormation operations and with permissions to retrieve and decrypt objects from the artifacts S3 bucket. In the CodePipeline account, configure the CodePipeline CloudFormation action to use the roles.

E : the development account and in the production account, create an IAM role for CodePipeline. Configure the roles with permissions to perform CloudFormation operations and with permissions to retrieve and decrypt objects from the artifacts S3 bucket. In the CodePipeline account, modify the artifacts S3 bucket policy to allow the roles access. Configure the CodePipeline CloudFormation action to use the roles.

Answer: B,D

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 DevOps engineer must implement a solution that immediately terminates Amazon EC2 instances in Auto Scaling groups when cryptocurrency mining activity is detected. Which solution will meet these requirements with the LEAST development effort?

A : Configure Amazon Route 53 query logs # CloudWatch # Lambda every 5 mins to detect mining-related domains and terminate EC2 instances.

B : Configure VPC Flow Logs # S3 # Lambda every 5 mins # Athena query # terminate EC2 instances.

C : Enable Amazon GuardDuty. Monitor EC2 findings. Create an EventBridge rule triggered by GuardDuty. Invoke a Lambda function that terminates the affected EC2 instances.

D : Enable AWS Security Hub. Monitor EC2 findings. Create an EventBridge rule triggered by SecurityHub. Invoke Lambda to terminate EC2 instances.
