The correct answer is D. Create a new private subnet to hold the required EC2 instances. A subnet’s CIDR block size determines how many IP addresses it can allocate to resources. Once all IP addresses in the subnet are used, you cannot expand or resize the CIDR block of an existing subnet. The only solution is to create a new subnet (with a larger or different CIDR…
Question
A CloudOps engineer creates a new VPC that includes a public subnet and a private subnet. The CloudOps engineer successfully launches 11 Amazon EC2 instances in the private subnet The CloudOps engineer attempts to launch one more EC2 instance in the same subnet. However, the CloudOps engineer receives an error message that states that not enough free IP addresses are available. What must the CloudOps engineer do to deploy more EC2 instances?
Options
- AEdit the private subnet to change the CIDR block to /27.
- BEdit the private subnet to extend across a second Availability Zone.
- CAssign additional Elastic IP addresses to the private subnet.
- DCreate a new private subnet to hold the required EC2 instances.

Explanation
A subnet’s CIDR block size determines how many IP addresses it can allocate to resources. Once all IP addresses in the subnet are used, you cannot expand or resize the CIDR block of an existing subnet. The only solution is to create a new subnet (with a larger or different CIDR range) within the same VPC and launch additional EC2 instances there. This allows scaling without IP address exhaustion.
