Create guest-VM subnets for each cluster.
Suggested answer: D

Explanation:

When creating user VM subnets for multiple NC2 clusters in AWS, the best approach is to create guest-VM subnets for each cluster. This ensures that each cluster has its own dedicated subnets, which simplifies network management and avoids potential IP conflicts.

Advantages of Dedicated Subnets:

Isolation: Each cluster operates in its own subnet, providing better isolation and security.

Management: Easier to manage and troubleshoot network issues when each cluster has its own subnets.

Scalability: More scalable as each subnet can be managed and expanded independently.

Steps to Create Guest-VM Subnets:

Identify the IP range for each subnet.

In the AWS VPC console, create a new subnet for each cluster using the identified IP ranges.

Associate the new subnets with the respective clusters during or after the cluster deployment process.

Why Not Shared Subnets:

Shared subnets could lead to IP conflicts and make network management more complex, especially as the number of clusters grows.
