take a long time because of long-running boot scripts. The CloudOps engineer must reduce scale-out

time without overprovisioning.

Which solution will meet these requirements?

A : Change the launch configuration to use a larger instance size.

B : Increase the minimum number of instances in the Auto Scaling group.

C : Add a predictive scaling policy to the Auto Scaling group.

D : Add a warm pool to the Auto Scaling group.

Question 2

A company has a VPC that contains a public subnet and a private subnet. The company deploys an Amazon

EC2 instance that uses an Amazon Linux Amazon Machine Image (AMI) and has the AWS Systems Manager

Agent (SSM Agent) installed in the private subnet. The EC2 instance is in a security group that allows only

outbound traffic.

A CloudOps engineer needs to give a group of privileged administrators the ability to connect to the instance

through SSH without exposing the instance to the internet.

Which solution will meet this requirement?

A : Create an EC2 Instance Connect endpoint in the private subnet. Update the security group to allowinbound SSH traffic. Create an IAM group for privileged administrators. Assign the PowerUserAccessmanaged policy to the IAM group.

B : Create a Systems Manager endpoint in the private subnet. Update the security group to allow SSHtraffic from the private network where the Systems Manager endpoint is connected. Create an IAMgroup for privileged administrators. Assign the PowerUserAccess managed policy to the IAM group.

C : Create an EC2 Instance Connect endpoint in the public subnet. Update the security group to allow SSHtraffic from the private network. Create an IAM group for privileged administrators. Assign thePowerUserAccess managed policy to the IAM group.

D : Create a Systems Manager endpoint in the public subnet. Create an IAM role that has theAmazonSSMManagedInstanceCore permission for the EC2 instance. Create an IAM group forprivileged administrators. Assign the AmazonEC2ReadOnlyAccess IAM policy to the IAM group.

Answer: A

Question 3

After the analysis is complete, the CloudOps engineer notices that some of the EC2 instances are missing

from the Compute Optimizer dashboard.

What is the likely cause of this issue?

A : The missing instances have insufficient historical Amazon CloudWatch metric data for analysis.

B : Compute Optimizer does not support the instance types of the missing instances.

C : Compute Optimizer already considers the missing instances to be optimized.
