What would be the best approach to take?

An administrator needs to create user VM subnets for multiple NC2 clusters in AWS.

What would be the best approach to take?
A . Create guest-VM VNets for each cluster.
B . Use the cluster management subnet dedicated to each cluster.
C . Create guest-VM subnets to be shared by all clusters.
D . Create guest-VM subnets for each cluster.

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.
