I think it's A, but I’m not 100% on that.

Wait, are you sure about that? I thought OSPF was more reliable.

Totally agree, IS-IS route should be the one.

Both routes? Nah, only one gets installed by default.

IS-IS has a higher default preference than OSPF.

I recall something about route preference, but I can't remember if it was about ECMP or just the default settings. This is tricky!

I practiced a similar question, and I think it was about ECMP. If both routes are valid, maybe they could both be installed?

I'm not entirely sure, but I feel like OSPF routes are usually preferred unless something else is at play.

I think I remember that IS-IS has a higher default administrative distance than OSPF, so maybe the IS-IS route would be preferred.

Wait, I'm confused. Does ECMP come into play here? I thought both routes would be installed if ECMP was enabled, but I'm not sure. I'll have to review the protocol details.

Okay, I've got this. The IS-IS route will be installed since it has internal reachability, which takes precedence over the OSPF type 5 LSA. Easy peasy!

Hmm, I'm a bit unsure about this. I know IS-IS and OSPF have different preferences, but I can't recall which one takes priority. I'll have to think this through carefully.

This is a tricky one, but I think I can figure it out. I'll need to remember the protocol preferences and how ECMP works.

I believe both routes will be installed regardless of ECMP, so option D.

But what if ECMP is enabled? Both routes could be installed then.

I agree with Merilyn, the IS-IS route should have higher preference.

Ooh, this one's tricky. I'm gonna go with 'C' - both routes will be installed if ECMP is enabled. Gotta love those redundant routing protocols!

I think the route learned via IS-IS will be installed.

Ha! I bet the answer is 'D' - both routes will be installed regardless of ECMP. Why make things simple when you can make them complicated, am I right?
