Question

A cloud engineer runs an automated deployment to launch 20 identical virtual machines in a region for a new environment. The first 12 VMs provision successfully, but the remaining 8 fail with an error stating the request could not be fulfilled. The deployment template is identical for all instances, the subnet has ample IP addresses, and IAM permissions allow instance creation. What is the MOST likely cause?

Accepted Answer

The account has reached a service quota (limit) for the number of instances of that type allowed in the region

Answer

The IAM role attached to the deployment lacks permission to create EC2 instances

Answer

The subnet CIDR block has been exhausted of available IP addresses

Answer

The deployment template contains a syntax error in the instance definition block
