CompTIA N10-009 Exam - Topic 5 Question 14 Discussion

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 1Port State Cost1 Forward 22 Forward 2Switch 2Port State Cost1 Forward 22 Forward 2Which of the following best describes the issue?
C) A root bridge needs to be identified.
A) The port cost should not be equal.
B) The ports should use link aggregation.
D) The switch should be configured for RSTP.

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

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.

Willard

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.

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