Get a glimpse of the real DOP-C01 certification exam challenges with our free Amazon DOP-C01 practice test questions.

Question 1

A company is using AWS Organizations and wants to implement a governance strategy with the following requirements:

* AWS resource access is restricted to the same two Regions for all accounts.

* AWS services are limited to a specific group of authorized services for all accounts.

* Authentication is provided by Active Directory.

* Access permissions are organized by job function and are identical in each account.

Which solution will meet these requirements?

AEstablish an organizational unit (OU) with group policies in the master account to restrict Regions and authorized services. Use AWS Cloud Formation StackSets to provision roles with permissions for each job function, including an IAM trust policy for IAM identity provider authentication in each account.

BEstablish a permission boundary in the master account to restrict Regions and authorized services. Use AWS CloudFormation StackSet to provision roles with permissions for each job function, including an IAM trust policy for IAM identity provider authentication in each account.

CEstablish a service control policy in the master account to restrict Regions and authorized services. Use AWS Resource Access Manager to share master account roles with permissions for each job function, including AWS SSO for authentication in each account.

DEstablish a service control policy in the master account to restrict Regions and authorized services. Use CloudFormation StackSet to provision roles with permissions for each job function, including an IAM trust policy for IAM identity provider authentication in each account.

Correct Answer: 1

Question 2

A development team manages website deployments using AWS CodeDeploy blue/green deployments. The application is running on Amazon EC2 instances behind an Application Load Balancer in an Auto Scaling group.

When deploying a new revision, the team notices the deployment eventually fails, but it takes a long time to fail. After further inspection, the team discovers the AllowTrafflc lifecycle event ran for an hour and eventually failed without providing any other information. The team wants to ensure failure notices are delivered more quickly while maintaining application availability even upon failure.

Which combination of actions should be taken to meet these requirements? (Select TWO.)

AChange the deployment configuration to CodeDeployDefault.AIIAtOnce to speed up the deployment process by deploying to all of the instances at the same time.

BCreate a CodeDeploy trigger for the deployment failure event and make the deployment fail as soon as a single health check failure is detected.

CReduce the HealthChecklntervalSeconds and UnhealthyThresholdCount values within the target group health checks to decrease the amount of time it takes for the application to be considered unhealthy.

DUse the appspec.yml file to run a script on the AllowTraffic hook to perform lighter health checks on the application instead of making CodeDeploy wait for the target group health checks to pass.

EUse the appspec.yml file to run a script on the BeforeAllowTraffic hook to perform health checks on the application and fail the deployment if the health checks performed by the script are not successful.

Correct Answer: 2

A, E

Question 3

A company maintains a stateless web application that is experiencing inconsistent traffic. The company uses AWS CloudFormation to deploy the application. The application runs on Amazon EC2 On-Demand Instances behind an Application Load Balancer (ALB). The instances run across multiple Availability Zones.

The company wants to include the use of Spot Instances while continuing to use a small number of On-Demand Instances to ensure that the application remains highly available.

What is the MOST cost-effective solution that meets these requirements?

AAdd a Spot block resource to the AWS CloudFormation template. Use the diversified allocation strategy with step scaling behind the ALB.

BAdd a Spot block resource to the AWS CloudFormation template. Use the lowest-price allocation strategy with target tracking scaling behind the ALB.

CAdd a Spot Fleet resource to the AWS CloudFormation template. Use the capacity-optimized allocation strategy with step scaling behind the ALB.

DAdd a Spot Fleet resource to the AWS CloudFormation template. Use the diversified allocation strategy with scheduled scaling behind the ALB

Correct Answer: 3

Question 4

A company runs several applications across multiple AWS accounts in an organization in AWS Organizations. Some of the resources are not tagged properly, and the company's finance team cannot determine which costs are associated with which applications. A DevOps engineer must remediate this issue and prevent this issue from happening in the future.

Which combination of actions should the DevOps engineer take to meet these requirements? (Select TWO.)

AActivate the user-defined cost allocation tags in each AWS account.

BCreate and attach an SCP that requires a specific tag.

CDefine each line of business (LOB) in AWS Budgets. Assign the required tag to each resource.

DScan all accounts with Tag Editor. Assign the required tag to each resource.

EUse the budget report to find untagged resources. Assign the required tag to each resource.

Correct Answer: 4

C, D

Question 5

A company has an application that is using a MySQL -compatible Amazon Aurora Multi-AZ DB cluster as the database A cross-Region read replica has been created for disaster recovery purposes A DevOps engineer wants to automate the promotion of the replica so it becomes the primary database instance in the event of a failure

Which solution will accomplish this?

AConfigure a latency-based Amazon Route 53 CNAME with health checks so it points to both the primary and replica endpoints Subscribe an Amazon SNS topic to Amazon RDS failure notifications from AWS CloudTrail and use that topic to trigger an AWS Lambda function that will promote the replica instance as the master.

BCreate an Aurora custom endpoint to point to the primary database instance Configure the application to use this endpoint Configure AWS CloudTrail to run an AWS Lambda function to promote the replica instance and modify the custom endpoint to point to the newly promoted instance.

CCreate an AWS Lambda function to modify the application's AWS CloudFormation template to promote the replica, apply the template to update the stack, and pout the application to the newly promoted instance Create an Amazon CloudWatch alarm to trigger this Lambda function after the failure event occurs

DStore the Aurora endpoint in AWS Systems Manager Parameter Store Create an Amazon EventBridge (Amazon CloudWatch Events) event that detects the database failure and runs an AWS Lambda function to promote the replica instance and update the endpoint URL stored in AWS Systems Manager Parameter Store Code the application to reload the endpoint from Parameter Store if a database connection fails.
