Hold up, did someone say 'Time Voyager'? I'm in! Can we also use that to go back and prevent all these cable and BGP issues from happening in the first place? Now we're talking!

I'm a bit concerned about option A. Reverting to the last working version? Isn't that just kicking the can down the road? I'd rather roll up my sleeves and dig into the actual problem.

D is definitely the answer! Who needs to look at the console or worry about agent connectivity when you can just consult the cable map? That's where the real magic happens!

Hmm, I'm not sure about that Time Voyager thing in option A. Sounds like some kind of sci-fi solution to me. I'd stick with the more practical options, like B or C.

I think option B is the best way to troubleshoot interface anomalies.

I think option B is the way to go. Accessing the console to review the interface states seems like the most direct approach to troubleshooting these issues.
