Implementing Cisco Edge Network Security Solutions (SENSS, legacy) — Question 9

Which command must be used to implement the unicast RPF feature on a Cisco ASA device?

Answer options

• A. ip verify source port-security
• B. ip source-route
• C. ip verify unicast reverse-path
• D. ip verify reverse-path interface <interface name>

Correct answer: C

Explanation

The correct answer is C, 'ip verify unicast reverse-path', as it specifically enables unicast Reverse Path Forwarding, which is essential for preventing spoofed packets. The other options do not relate to the unicast RPF implementation: A pertains to port security, B relates to source routing, and D specifies a different verification command without enabling the unicast RPF feature.
