300-415 Question #120: Real Exam Question with Answer & Explanation
The correct answer is B: The default route is learned via OMP.. The routing table output from a branch office, likely from a cEdge router, verifies that the default route (0.0.0.0/0) is learned via OMP.
WAN Edge Router Deployment
Question
Refer to the exhibit. The network administrator has configured a centralized topology policy that results in the displayed routing table at a branch office. Which two configurations are verified by the output? (Choose two.)
Options
- AThe routing table is for the transport VPN.
- BThe default route is learned via OMP.
- CThis routing table is from a cEdge router.
- DThe default route is configured locally.
- EThe configured policy is adding a route tag of 300 to learned routes.
Explanation
The routing table output from a branch office, likely from a cEdge router, verifies that the default route (0.0.0.0/0) is learned via OMP.
Common mistakes.
- A. Routing tables are typically viewed for service VPNs (e.g., VPN 1-65535) where user data resides, not primarily for the transport VPN (VPN 0) which handles underlay connectivity and control plane communication.
- D. If the default route were configured locally on the device, its source and administrative distance would typically differ from an OMP-learned route, which is implicitly not the case given option B is correct.
- E. Without the actual exhibit, there is no information in the question that supports the conclusion that a route tag of 300 is being added by a configured policy.
