Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 99

What from the following can cause an issue for uRPF?

Answer options

• A. Asymetric routing
• B. CEF not enabled
• C. uRPF not applied to the traffic source
• D. if it is used as ingress filtering

Correct answer: A

Explanation

Asymmetric routing can cause uRPF to fail because it relies on the return path being the same as the forward path for validation. The other options, while they may represent configuration or implementation issues, do not directly lead to routing inconsistencies that would disrupt the uRPF functionality.
