Show Suggested Answer Hide Answer
Suggested Answer: B

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.

I feel like option C might be the right choice since it looks familiar, but I can't shake the feeling that I need to double-check the rules for inbound and outbound traffic.

If I remember correctly, the security group should allow inbound traffic from 10.19.160.0/24, but I’m a bit confused about whether it should specify the protocol as well.

I think we practiced a similar question where we had to allow access from a specific IP range, but I can't recall the exact formatting for the security group rules.

I remember we discussed security groups allowing specific CIDR blocks, but I'm not sure if it should be set to allow all traffic or just specific protocols.
