[All NCP-CI-Azure Questions]

An administrator deploys an NC2 cluster in Azure and uses 10.100.0.0/16 for one of the VNets.

The cluster is configured as follows:

* 8 nodes

* Prism Central Deployed

* Files Deployed

Following the deployment, the administrator experiences network connectivity issues.

Which reason explains the connectivity issues?

Show Suggested Answer Hide Answer
Suggested Answer: B

Network Configuration: Using a specific IP range for a VNet can cause conflicts if that range is reserved or already in use by the cluster's internal operations.

Internal Usage: In NC2, certain IP ranges are reserved for internal cluster functions and should not be used for VNets to avoid IP conflicts and connectivity issues.

Impact: If the 10.100.0.0/16 range is reserved for internal usage, using it for a VNet would lead to IP conflicts, causing network connectivity issues.

Verification: It's important to verify the reserved IP ranges in the NC2 documentation before assigning them to VNets.

Conclusion: The connectivity issues are likely due to using the 10.100.0.0/16 range, which is reserved for internal cluster usage.

I think it's B. Reserved for internal use.

D sounds plausible, but I doubt IANA reserves that range.

C doesn't make sense, that's a huge range for an NC2 cluster.

Wait, isn't 10.100.0.0/16 a private range?

10.100.0.0/16 is a valid CIDR range.

D sounds familiar, but I can't recall if 10.100.0.0/16 is specifically reserved by IANA. It could be a possibility.

I practiced a similar question, and I think C is unlikely because NC2 clusters can handle large IP ranges.

I'm not entirely sure, but I think B might be the right answer since some IP ranges are reserved for specific uses.

I remember reading that the 10.100.0.0/16 range is actually a valid CIDR range, so I don't think A is correct.
