Question 1

A company has a stateless web application that is deployed on Amazon EC2 instances. The EC2 instances are in a target group behind an Application Load Balancer (ALB). Amazon Route 53 manages the application domain.

The company updates the application UI and develops a beta version of the application. The company wants to test the beta version on 10% of its traffic.

Which solution will meet these requirements with the LEAST number of configuration changes?

Options:

A.

Deploy the beta version to new EC2 instances in a new target group. Associate the new target group with a new ALB. Update the existing Route 53 record to use a weighted routing policy. Add a new Route 53 record that points to the new ALB with the same routing policy. Assign a weight of 90 to the existing record. Assign a weight of 10 to the new record.

B.

Deploy the beta version to new EC2 instances in a new target group. Associate the new target group with the same ALB listener rule. Assign a weight of 90 to the existing target group. Assign a weight of 10 to the new target group.

C.

Refactor the application to implement a feature flag for the beta version by using AWS AppConfig. Use the feature flag to enable the beta version for 10% of the EC2 instances.

D.

Containerize and deploy the application on Amazon Elastic Container Service (Amazon ECS). Use AWS CodeDeploy to deploy the beta version by using the CodeDeployDefault.ECSCanary10Percent15Minutes deployment configuration.

Question 2

A company uses an organization in AWS Organizations to manage multiple AWS accounts. The company ' s internal auditors have administrative access to a single audit account within the organization. A DevOps engineer needs to provide a solution to give the auditors read-only access to all accounts within the organization, including new accounts created in the future. Which solution will meet these requirements?

Options:

A.

Enable AWS IAM Identity Center for the organization. Create a read-only access permission set. Create a permission group that includes the auditors. Grant access to every account in the organization to the auditor permission group by using the read-only access permission set.

B.

Create an AWS CloudFormation stack set to deploy an IAM role that trusts the audit account and allows read-only access. Enable automatic deployment for the stack set. Set the organization root as a deployment target.

C.

Create an SCP that provides read-only access for users in the audit account. Apply the policy to the organization root.

D.

Enable AWS Config in the organization management account. Create an AWS managed rule to check for a role in each account that trusts the audit account and allows read-only access. Enable automated remediation to create the role if it does not exist.

A.

Create a repository in Amazon Elastic Container Registry (Amazon ECR). Add a lifecycle policy to the repository to expire images that have the matching tag after 15 days.
