Question 2

A rapidly growing company wants to scale for developer demand for AWS development environments. Development environments are created manually in the AWS Management Console. The networking team uses AWS CloudFormation to manage the networking infrastructure, exporting stack output values for the Amazon VPC and all subnets. The development environments have common standards, such as Application Load Balancers, Amazon EC2 Auto Scaling groups, security groups, and Amazon DynamoDB tables.

To keep up with demand, the DevOps engineer wants to automate the creation of development environments. Because the infrastructure required to support the application is expected to grow, there must be a way to easily update the deployed infrastructure. CloudFormation will be used to create a template for the development environments.

Which approach will meet these requirements and quickly provide consistent AWS environments for developers?

Options:

A.

Use Fn::ImportValue intrinsic functions in the Resources section of the template to retrieve Virtual Private Cloud (VPC) and subnet values. Use CloudFormation StackSets for the development environments, using the Count input parameter to indicate the number of environments needed. Use the UpdateStackSet command to update existing development environments.

B.

Use nested stacks to define common infrastructure components. To access the exported values, use TemplateURL to reference the networking team’s template. To retrieve Virtual Private Cloud (VPC) and subnet values, use Fn::ImportValue intrinsic functions in the Parameters section of the root template. Use the CreateChangeSet and ExecuteChangeSet commands to update existing development environments.

C.

Use nested stacks to define common infrastructure components. Use Fn::ImportValue intrinsic functions with the resources of the nested stack to retrieve Virtual Private Cloud (VPC) and subnet values. Use the CreateChangeSet and ExecuteChangeSet commands to update existing development environments.

D.

Use Fn::ImportValue intrinsic functions in the Parameters section of the root template to retrieve Virtual Private Cloud (VPC) and subnet values. Define the development resources in the order they need to be created in the CloudFormation nested stacks. Use the CreateChangeSet. and ExecuteChangeSet commands to update existing development environments.

Question 3

A company runs an application in an Amazon Elastic Container Service (Amazon ECS) service that is associated with an Elastic Load Balancing (ELB) target group. A DevOps engineer updates the service to include a new task definition version. The DevOps engineer notices that the deployment does not finish running. New tasks enter a stopped state soon after the tasks launch. The task definition references an Amazon CloudWatch Logs log group.

Which issues are most likely the cause of the failing deployment? (Select TWO.)

Options:

A.

The target group health check is failing, which causes Amazon ECS to stop the tasks.

B.

The IAM role that the DevOps engineer used to update the ECS service does not have the Amazon ECS RunTask permission.

C.

The CloudWatch Logs log group that is referenced in the task definition does not exist.

D.

The task role does not have the required permissions to launch the task.

E.

An essential container in the ECS task is exiting.
