I practiced a similar question last week, and I think the answer was FALSE because Backup Ports are meant for different links.

I feel like this is a trick question. I thought Backup Ports were only for redundant links, but I can't remember if they share the same switch.

I've got a good handle on RSTP, so I'm confident I can figure this out. Let me just take a moment to refresh my memory.

Krystina 9 months ago
Ah, this is a tricky one. I'll have to think through the RSTP logic carefully to determine the correct answer.

Okay, I think I know how to approach this. The key is understanding the RSTP port roles and how they're assigned on a per-port basis.
