What is the purpose of WJH (What Just Happened)?

Show Suggested Answer Hide Answer
Suggested Answer: A

NVIDIA's What Just Happened (WJH) is a feature that provides real-time visibility into network problems by analyzing all packets passing through the switch and alerting on performance issues caused by packet drops, congestion, high latency, or misconfigurations.

WJH retains the last packets that were dropped from the switch with complete packet headers and the actual drop reason. This enhances the ability to debug network problems, identify affected flows, and decrease time-to-repair.

I’m a bit confused; I thought WJH was about notifications for failed logins, but that doesn’t seem right now.

I feel like WJH could also relate to system logs, but that seems more like a different function.

I remember a practice question that mentioned identifying unusual traffic patterns, so I might lean towards option C.

I think WJH is about providing context for dropped packets, but I'm not entirely sure if that's the main focus.

Hmm, I'm a bit confused on this one. I know WJH has something to do with logging and diagnostics, but I'm not sure which of these options is the correct purpose. I'll have to think it through carefully.

I think C is the best answer here. WJH is all about monitoring the network for potential security issues, right? I'm pretty confident in that.

I've seen WJH mentioned before, but I can't quite remember the specifics. I'll try to eliminate the options that don't seem to fit and see if I can narrow it down.

Okay, let's see... I'm leaning towards C, but I'm not 100% sure. I'll need to double-check the details on what WJH is actually used for.
