CompTIA N10-009 Exam - Topic 5 Question 14 Discussion

Actual exam question for CompTIA's N10-009 exam

Question #: 14
Topic #: 5

A network engineer configures a new switch and connects it to an existing switch for expansion and redundancy. Users immediately lose connectivity to the network. The network engineer notes the following spanning tree information from both switches:

Switch 1

Port State Cost

1 Forward 2

2 Forward 2

Switch 2

Port State Cost

1 Forward 2

2 Forward 2

Which of the following best describes the issue?

AThe port cost should not be equal.

BThe ports should use link aggregation.

CA root bridge needs to be identified.

DThe switch should be configured for RSTP.

Link aggregation might help, but not the main issue here.

I thought RSTP was only for faster convergence, not this issue.

Wait, does that mean a loop could happen?

Totally agree, they shouldn't match!

The port costs are the same, that's a problem.

I thought link aggregation was important for redundancy, but I'm not convinced that's the problem in this scenario.

I feel like the switches should be configured for RSTP, but I can't recall the exact benefits of that over STP.

This seems similar to a practice question where we had to identify the root bridge. I think that might be relevant here too.

I remember something about spanning tree protocols, but I'm not sure if the port costs being equal is the main issue here.

Hmm, I'm a bit confused. The port states are all forwarding, so I'm not sure why they would be losing connectivity. Maybe I'm missing something about the spanning tree configuration.

The port costs are the same on both switches, so that's probably not the issue. I'm thinking it might be a root bridge problem.

This looks like a spanning tree issue. I'll need to carefully review the port states and costs to identify the problem.

Okay, I think I've got it. Since the ports are all forwarding, the issue is likely that the switches don't have a defined root bridge. I'll need to identify the root bridge and make sure the port costs are set up correctly.

I remember practicing regex questions like this, but I'm unsure if "C" and "E" are the correct matches.

Clearly, the issue is that the port costs are equal. They need to be different to ensure proper load balancing and redundancy.

Haha, the engineers must have been having a tech-comedy show when they set this up. RSTP, really? That's like using a rubber hammer to fix a leaky faucet.

C'mon, link aggregation is the way to go! Spread that traffic across multiple ports for maximum efficiency.

Aha! The root bridge needs to be identified. That must be the issue here. The switches are fighting over who's the boss.

That makes sense. Let's check the spanning tree configuration to ensure proper election.

No, it's better to let the switches elect the root bridge automatically.

Should we manually configure the root bridge?

Yes, you're right. The switches need to determine who the root bridge is.

Wait, shouldn't the port costs be different? I thought redundancy meant having different paths with varying costs.

Ah, I see the problem. The switch should be configured for RSTP to handle this situation and avoid the network outage. D is the way to go.

Haha, this is like a game of musical chairs for network devices! The engineers need to figure out who's the 'root' switch before the users get disconnected.
