Free Amazon DOP-C02 Exam Questions

Question 1

A leading software development company has various web applications hosted in an Auto Scaling group of EC2 instances which are designed for high availability and fault tolerance. They are using AWS CloudFormation to easily manage their cloud infrastructure as code as well as for deployment. Currently, they have to manually update their CloudFormation templates for every new available AMI of their application. This procedure is prone to human errors and entails a high management overhead on their deployment process.

Which of the following is the MOST suitable and cost-effective solution that the DevOps engineer should implement to automate this process?

A : ll the new AMI IDs using an AWS Lambda-backed custom resource in the CloudFormation template. Reference the AMI ID that the custom resource fetched in the launch configuration resource block.

B : nfigure the CloudFormation template to use AMI mappings. Integrate AWS Lambda and Amazon CloudWatch Events to create a function that regularly runs every hour to detect new AMIs as well as update the mapping in the template. Reference the AMI mappings in the launch configuration resource block.

C : nfigure the AWS CloudFormation template to use conditional statements to check if new AMIs are available. Fetch the new AMI ID using the cfn-init helper script and reference it in the launch configuration resource block.

D : unch an EC2 instance to run a custom shell script every hour to check for new AMIs. The script should update the launch configuration resource block of the CloudFormation template with the new AMI ID if there are new ones available.

Answer: A

Question 2

Your API servers are hosted on a cluster of EC2 instances deployed using Elastic Beanstalk. You need to deploy a new version and also change the instance type of the instances from m4.large to m4.xlarge. Since this is a production workload already operating at 80?pacity, you want to ensure that the workload on the current EC2 instances does not increase while doing the deployment.

Which of the following deployment policy will you implement which will incur the LEAST amount of cost?

A : Immutable as deployment policy to deploy the new version with complete capacity.

B : Rolling as the deployment policy to maintain the capacity of the cluster during the deployment.

C : All at once as deployment policy to deploy the new version with complete capacity.

D : Rolling with additional batch as deployment policy to maintain the capacity of the cluster during the deployment.

Answer: D

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 has an on-premises application that is written in Go. A DevOps engineer must move the application to AWS. The company's development team wants to enable blue/green deployments and perform A/B testing.

Which solution will meet these requirements?

A : ploy the application on an Amazon EC2 instance, and create an AMI of the instance. Use the AMI to create an automatic scaling launch configuration that is used in an Auto Scaling group. Use Elastic Load Balancing to distribute traffic. When changes are made to the application, a new AMI will be created, which will initiate an EC2 instance refresh.

B : Amazon Lightsail to deploy the application. Store the application in a zipped format in an Amazon S3 bucket. Use this zipped version to deploy new versions of the application to Lightsail. Use Lightsail deployment options to manage the deployment.

C : AWS CodeArtifact to store the application code. Use AWS CodeDeploy to deploy the application to a fleet of Amazon EC2 instances. Use Elastic Load Balancing to distribute the traffic to the EC2 instances. When making changes to the application, upload a new version to CodeArtifact and create a new CodeDeploy deployment.

D : AWS Elastic Beanstalk to host the application. Store a zipped version of the application in Amazon S3. Use that location to deploy new versions of the application. Use Elastic Beanstalk to manage the deployment options

Answer: D

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
