Question #: 92
Topic #: 4

Refer to the exhibit.

Refer to the exhibit. An engineer proposed this solution for a company that requires a loop-free. Layer 2 network design. The network will run 802.1W, and all links will be 1 Gbps. If all interfaces are up as point- to-point adjacencies, what are the expected port end states based on the design?

AEth1/2 on SW2 and SW3 will be in a Desg FWD state

BEth1/3 on SW2 and SW3 will be m an Attn BLK state

CEth1/2 on SW3 and SW4 will be m an Attn BLKbtate.

DEth1/1 on SW1 and SW2 will be in a Root FWD state.

Ah, the joys of network design! I bet the engineer who came up with this solution was feeling pretty clever. Probably sitting there, sipping their coffee, and thinking, 'Wait until they see this one!' I mean, how many times have we all been in that position, where we think we've got the perfect solution, only to have it fall apart like a house of cards? It's all part of the fun, I suppose.

I'm not sure, but I think the answer might be D) Eth1/1 on SW1 and SW2 will be in a Root FWD state.

Hmm, this is a tricky one. I'm going to go with option D, since it seems to align with the RSTP protocol mentioned in the question. Although, I have to say, the thought of all the ports being in a 'Desg FWD' state is making me a little dizzy. This network design must be a real party!
