Haha, looks like R2 is having an identity crisis. B) 10.10.10.66 is the way to go.

B) 10.10.10.66 - The question is straightforward, but I'm still second-guessing myself. Curse these certification exams!

B) 10.10.10.66 - Easy peasy, just gotta pay attention to the last command.

Hmm, I thought the router ID was supposed to be a unique identifier. Guess R2 didn't get the memo.

B) 10.10.10.66 - The second command overwrites the first, so the router ID for R2 will be 10.10.10.66.

I’m a bit confused because I thought the router ID was set only once at startup. Does it change dynamically with these commands?

This seems similar to a practice question I did where the last command took precedence. So, I’m leaning towards option B.

I remember something about OSPF router IDs, but I'm not sure if the last command overrides the first one.

Hmm, good point about the router ID propagation. I'm still not 100% sure, but I think I'll go with B as my best guess. I'll make sure to double-check my work before submitting the answer.

Based on my understanding, the router ID used by OSPF is updated as soon as the commands are executed. So the answer should be 10.10.10.66, which is the last router ID that was set. I'll go with B.

Wait, I'm a bit confused. Does the router ID used by OSPF get updated immediately after the commands are executed, or does it take some time to propagate? I'm not sure which router ID R1 would see.

I think the router ID should be the last one configured, which is 10.10.10.66, but I could be mixing it up with another protocol.

C) 10.10.10.2 - Wait, what? That can't be right... or can it?

Okay, let's see here. The first command sets the OSPF router ID to 10.10.10.99, but the second command overwrites that with 10.10.10.66. I think the answer has to be B.

Hmm, this looks like a tricky OSPF configuration question. I'll need to carefully read through the command sequence and think about how OSPF router IDs are set.
