Implementing Cisco Service Provider Advanced Solutions (SPCOR2) — Question 22

Which feature enables service function chaining to steer traffic to virtual network functions?

Answer options

• A. GRE
• B. VXLAN
• C. EH
• D. NSH
• E. REST

Correct answer: B

Explanation

The correct answer is B, VXLAN, as it provides a way to encapsulate Layer 2 Ethernet frames within Layer 3 packets, which is essential for service function chaining. The other options, while related to networking, do not specifically facilitate the steering of traffic to virtual network functions in the same manner that VXLAN does.
