HPE7-A08 Exam - Topic 1 Question 4 Discussion

Actual exam question for HP's HPE7-A08 exam

Question #: 4
Topic #: 1

You are implementing a design where the campus network should be in an isolated spanning tree topology from the data centre network. The core switches are connected by a single Layer-2 interface carrying multiple VLANs.

When you examine the switches, you discover that the campus core sees the data centre core as the root bridge.

What configuration can you apply to the campus-to-data centre core link to resolve the issue?

ARoot guard

Wait, can BPDU guard really fix this? Sounds off.

Admin edge? Never heard of that one.

BPDU guard seems like it could help, but I thought it was more about protecting against loops rather than isolating the topology.

Admin edge sounds familiar, but I can't recall its exact function in this context. I feel like it might not be the best option.

I'm not entirely sure, but I think BPDU filtering could be risky since it might block all BPDUs. I need to double-check that.

I remember studying about root guards and how they can prevent a non-root bridge from becoming the root. That might be the right choice here.

This is a good test of our spanning tree knowledge. I'm pretty confident BPDU guard is the right choice to resolve the root bridge issue on the campus-to-data center link.

I'm not totally sure about this one. Admin edge could also be an option to isolate the campus network, right? I'll have to think it through a bit more.

Okay, let me think this through. Since the campus core sees the data center core as the root, we need to prevent that from happening. I'm leaning towards BPDU filter as the best solution.

Hmm, I'm a bit confused. Wouldn't root guard be a better option to prevent the data center core from becoming the root bridge?

BPDU filter? Nah, that's just going to disable the entire link. We need something more targeted. I'm going with BPDU guard.

Hmm, root guard seems like the obvious choice. It'll force the campus core to be the root bridge, right? Simple and effective.

I think BPDU guard is the way to go here. That'll prevent the data center core from becoming the root bridge and messing up the campus network topology.
