Free Cisco 300-415 Actual Exam Questions - Question 3 Discussion

B/D? B raises the cost on the WAN interface itself, which directly impacts OSPF path preference by making that exit less attractive. D also looks similar but might be messing with routing preferences in a broader way, maybe more global than just interface cost. Since the question focuses on making one exit less preferred, the interface-specific cost tweak in B makes more sense here. The other options seem less targeted for this exact purpose.

B/C? B changes the OSPF cost on the interface itself, which directly affects route preference. C looks close too but might be more about overall router priority, not just exit path preference.

Good points about interface specifics. I’d say D because it increases the cost on the secondary WAN link, clearly making it less preferred for exit. That direct cost hike fits the question well. D

Probably B here. It uses the "ip ospf cost" command but on the WAN interface you want to de-prioritize, so it directly influences OSPF path selection by raising the cost, making that exit less preferred.

Maybe C, since changing the cost on the specific WAN interface directly affects preference. If that command bumps the metric higher, it’d definitely make that edge less preferred compared to the other.

I’m going with D here because tweaking the OSPF cost directly on the WAN interface is the usual way to make that path less preferred. The other options seem more about general OSPF settings or redistribution, which won’t specifically change route preference on the WAN link. So, option D fits best with the idea of controlling exit preference in a dual WAN setup.

D, it’s the only one explicitly adjusting OSPF cost on the WAN interface directly.

B tbh, I’d go with D here. Changing the interface metric in OSPF is the usual way to influence path selection, and option D shows adjusting the cost on the WAN interface directly. The others are either global router settings or don’t specifically tweak the WAN exit preference. This command fits the scenario of making one WAN less preferred better than just a general config tweak.

It’s C. Options A and B are more about basic OSPF settings, not adjusting route preference like this. C looks like the command that tweaks the cost, making that WAN less preferred.
