Wait, can the ONU really trigger protection reversals? Sounds odd.

Yeah, OLT doesn't just "laugh" at status changes!

I vaguely remember that the work port should switch to standby, but I’m not confident if that’s the case when the OLT port goes down.

I think the ONU should definitely detect link failures, so option D seems correct. But I'm a bit confused about the specifics of the protection reversal process.

This question feels similar to one we practiced about OLT and ONU interactions. I think option B sounds really off, but I can't recall the exact reason.

I remember studying how protection mechanisms work in GPON, but I'm not entirely sure what happens to the ONU when the OLT port goes down.

I've got this! The answer is a service endpoint policy. That way, we can restrict the VMs to only access storage1, while still allowing public internet access to the storage account.

I feel pretty confident about this one. The key is that Mrs. Newbie-Oldman is a registered rep, so she needs her firm's approval to be added to the account. And her husband also has to provide written authorization. So the answer is definitely D.

I think the other options involve profit or equity, but I'm pretty sure it's not just a gain in profit or loss. I might be overthinking it!

Hmm, I'm not totally sure about this one. I know Snort is an IDS, but I'm not sure if it can detect wireless attacks specifically. I'll have to think this through carefully.
