Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 18

Answer options

• A. unicast flooding
• B. uRPF failure
• C. errdisabling of ports
• D. port security violations
• E. excessive STP convergence AB

Correct answer:

Explanation

The correct answers are A and B. Unicast flooding occurs because packets may take unexpected paths, leading to duplication, while uRPF (Unicast Reverse Path Forwarding) can fail due to the mismatch between the routing paths. Options C, D, and E may occur due to other network issues but are not direct effects of asymmetric routing.
