C is wrong, OSPF uses Dijkstra's algorithm, not Bellman-Ford.

LSDB updates are not every 30 mins, that's a myth.

Wait, OSPF floods LSU packets every 5 seconds? That seems too frequent!

I vaguely remember something about LSU packets, but I can't remember if the flooding interval is 5 seconds or something else.

I practiced a question about OSPF algorithms, and I thought it used Dijkstra's algorithm, not Bellman-Ford.

I think OSPF updates its LSDB more frequently than every 30 minutes, but I can't recall the exact interval.

I remember OSPF doesn't use TCP for acknowledgments, but I'm not sure if that's because it has its own mechanism or something else.

I know OSPF uses the Dijkstra algorithm, not Bellman-Ford, so option C is definitely wrong.

Okay, I've got this. Management traffic is stuff like SNMP, which is used to monitor and configure network devices. ICMP is the diagnostic protocol, so that's the answer here. Easy peasy!

I hope the next question is about which OSPF routers are the most fashionable. I've been working on my router-runway look.
