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?

Not convinced this design will actually work as intended.

Eth1/1 on SW1 and SW2 will definitely be in a Root FWD state!

Wait, are we sure about Eth1/3 being in an Attn BLK state?

Totally agree, that makes sense!

Eth1/2 on SW2 and SW3 should be in a Desg FWD state.

I recall that in a loop-free design, some ports will definitely be blocked, but I can't remember which ones specifically. This is tricky!

I think Eth1/3 on SW2 and SW3 being in a blocking state makes sense, but I’m not confident about the other options.

This question feels similar to one we practiced where we had to determine port states based on the root bridge. I think Eth1/2 on SW2 and SW3 might be in a forwarding state, but I could be wrong.

I remember studying the spanning tree protocol, but I'm not entirely sure how the port states will be affected in this specific design.

Alright, I've got a strategy. I'll start by identifying the root bridge, then determine the port roles on each switch based on the 802.1W protocol. That should lead me to the right answer.

I'm a bit confused by the wording of the question. What exactly does "loop-free Layer 2 network design" mean? I'll have to re-read the details carefully.

Okay, let me think this through step-by-step. The key is understanding how 802.1W handles redundant links to prevent loops. I'll need to identify the root bridge and work from there.

Hmm, this looks like a tricky spanning tree question. I'll need to carefully analyze the network topology and the 802.1W protocol to determine the expected port states.

This seems straightforward. The exhibit shows a simple redundant topology, so the port states should be pretty clear once I apply the 802.1W rules. I'm confident I can get this one right.

Okay, let's think this through step-by-step. The question is asking for the CPI, which is the Cost-Performance Index. To calculate this, I need to use the formula CPI = EV / AC, where EV is the Earned Value and AC is the Actual Cost.

This seems like a straightforward question about how sampling error can impact job analysis. I'll need to think through the potential issues that could arise from a non-representative sample.

I've got a good feeling about this one. Based on my understanding of architecture frameworks, the Standards Information Base is likely a repository for the standards and guidelines that architectures need to conform to. I'll go with that option.

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!

Haha, this question is like a game of Tetris - you've got to figure out where all the pieces fit! I'm going to go with option A, just for the fun of it. Who knows, maybe the engineer had a trick up their sleeve.

I'm not too sure about this one. The question mentions a loop-free Layer 2 network design, so I'm thinking the ports might not be in a forwarding state. Maybe option B or C could be correct, with the ports in an Alternate or Backup state.
CA

Okay, let's think this through. The question is asking about the expected port end states based on the given design. I'm leaning towards option D, as the engineer mentioned that the network will run 802.1W, which is Rapid Spanning Tree Protocol. In RSTP, one of the ports will be selected as the root port, and that should be Eth1/1 on SW1 and SW2.
SA

I agree with Brendan, because in a loop-free design with 802.1W, those ports should be in a forwarding state.

I think the answer is A) Eth1/2 on SW2 and SW3 will be in a Desg FWD state.
