It reverts if precedence is set to 'primary'.

It never reverts, right? That’s what I thought.

I believe it reverts if the precedence is lower than the active link, but I need to double-check that.

I practiced a similar question, and I feel like it won't always revert, but I can't remember the specific conditions.

I think it might revert if the failed link has a higher priority, but I can't recall the exact details.

I remember something about link precedence, but I'm not sure if it has to be set to 0 or if any lower value works.

I'm pretty confident I know the answer to this one. It's option D - the active pseudowire will revert if the precedence of the previously failed link is lower than the currently active link.

Okay, I think I've got this. The key is understanding the precedence settings on the pseudowires. If the precedence of the previously failed link is lower, then it will revert back to that link.

Hmm, I'm a bit confused about the details of how Active/Standby pseudowires work. I'll need to review my notes to make sure I understand the precedence rules.

This seems like a tricky question about pseudowire failover. I'll need to think carefully about the different scenarios.

Hmm, I'm not sure about this one. The code looks complex, and I'm not familiar with all the C++ features being used. I'll need to take some time to carefully analyze the code step-by-step to figure out the correct answer.

Ah, the joys of pseudowire troubleshooting. I can't wait to put this knowledge to use in the real world... or at least on the exam.

I wonder if the exam question author has ever actually experienced a failed pseudowire in real life. Maybe they just made this up to trip us all up!

B is definitely wrong. Why would the active pseudowire never revert to the previously failed link? That doesn't make any sense. I'm going with D as the correct answer.

Hmm, I'm torn between C and D. I guess it really depends on how the network is configured. Either way, I hope I don't have to troubleshoot any failed pseudowires on the exam!

Option C makes the most sense to me. The question specifically mentions 'previously failed link', so the active pseudowire should revert back to that link if the precedence is set to primary.

But what if the precedence of the previously failed link is higher than the currently active link? Would it still revert?
