Question #: 116
Topic #: 4

[All Professional Cloud Network Engineer Questions]

Your organization recently re-architected your cloud environment to use Network Connectivity Center. However, an error occurred when you tried to add a new VPC named vpc-dev as a spoke. The error indicated that there was an issue with an existing spoke and the IP space of a VPC named vpc-pre-prod. You must complete the migration quickly and efficiently. What should you do?

DExclude the conflicting IP range by using the --exclude-export-ranges flag in the hub when attaching the VPC spoke for vpc-dev.

BDelete the VMs associated with the conflicting subnets, then delete the conflicting subnets in vpc-dev. Recreate the subnets with a new IP range and redeploy the previously deleted VMs in the new subnets. Add the VPC spoke for vpc-dev.

CExclude the conflicting IP range by using the --exclude-export-ranges flag when creating the VPC spoke for vpc-dev.

ARemove the conflicting VPC spoke for vpc-pre-prod from the set of VPC spokes in Network Connectivity Center. Add the VPC spoke for vpc-dev. Add the previously removed vpc-pre-prod as a VPC spoke.

Show Suggested Answer

Suggested Answer: A

The most efficient way to resolve the conflict is to temporarily remove the conflicting vpc-pre-prod spoke, add the vpc-dev spoke, and then re-add vpc-pre-prod. This ensures that the migration happens quickly without the need to change IP ranges or delete resources.

I'm not entirely sure, but could it be possible that vpc-pre-prod is still connected to another service that's causing the conflict?

I think I saw a similar question in our practice exams where we had to resolve overlapping IP ranges. Should we consider renaming or changing the CIDR of vpc-pre-prod?

I remember something about IP address conflicts causing issues when adding spokes. Maybe we need to check the CIDR blocks for both VPCs?

I'm a bit confused by the technical details here, but I'll do my best to work through this step-by-step. First, I'll need to gather more information about the existing vpc-pre-prod VPC and the issue with the IP space. Then, I'll see if I can come up with a solution to resolve the conflict and complete the migration.

This seems straightforward enough. I'll start by checking the IP space of the vpc-pre-prod VPC and see if I can find a way to adjust it to avoid the conflict. If that's not possible, I may need to consider other options like modifying the vpc-dev VPC or exploring alternative network configurations.

Okay, so it seems like there's a problem with the IP space of the vpc-pre-prod VPC that's causing issues when trying to add the new vpc-dev VPC as a spoke. I'll need to investigate the IP ranges of both VPCs and see if I can find a way to resolve the conflict.

Hmm, this looks like a tricky one. I'll need to carefully review the requirements and see if I can identify the root cause of the issue with the existing spoke and IP space conflict.
