Answer: B

Explanation:

To allow wide open access to a particular NC2 AWS cluster from an on-premises subnet (10.19.160.0/24), the proper Custom Security Group formatting needs to include the necessary tags that specify the external cluster UUID and the networks allowed.

Custom Security Group Configuration:

The configuration should include tags to identify the cluster and the networks that should be granted access.

Key: nutanix:clusters

Key: nutanix:clusters:external

Value: <cluster-uuid>

Explanation of Choice:

Option B includes the necessary tags and values, ensuring that the specific cluster UUID is recognized and the on-premises subnet (10.19.160.0/24) can communicate with the NC2 cluster.

Security Group Tags:

nutanix:clusters:external – Identifies the cluster as external.

nutanix:clusters:external:cluster-uuid – Specifies the unique identifier for the cluster, enabling proper traffic routing and access.
