Free Cisco SPRI 300-510 Actual Exam Questions - Question 14 Discussion
Refer to the exhibit. An engineer working for a private telecommunication company with an
employee id: 4233:46:364 notices that the customer network going through AS30-AS65001-AS65000
is experiencing packet drops when it accesses an application at 172.16.20.1/32 In the DC cloud. The
BGP link between AS20 and AS30 is inaccessible because of a fiber cut. Routers RL, RN, and RZ are
configured with confederation identifier 10. Which action resolves this Issue?
Option C, because fixing internal confederation routing can prevent drops despite external link failure.
It’s B, because rerouting around the fiber cut is key here, not just internal tweaks.
B/D? Option B restores connectivity around the fiber cut by rerouting externally, while D could optimize internal confederation routes. Since the cut blocks AS20-AS30, B looks like the immediate fix.
B/C? The confederation ID setup suggests internal rerouting, so option C might improve path selection within the confederation. B’s good for external failover, but internal tweaks can reduce packet drops more directly.
C seems off since confederation should handle internal routes better than that.
Makes sense that B is good, but I think D also deserves a look since it might reroute traffic around the broken link better. The confederation could be key in that option too. D
Option B looks solid here. The fiber cut between AS20 and AS30 messes with the path, so rerouting through confederation should fix it. A might be tempting but looks like a trap since it won't handle the cut well.
