JNCIA-Cloud: Juniper Networks Certified Associate – Cloud — Question 12

Which protocol would be used by the NorthStar Controller to learn the topology of the WAN network?

Answer options

• A. IS-IS
• B. RIP
• C. PCEP
• D. MPLS

Correct answer: C

Explanation

The correct answer is C, PCEP, as it is specifically designed for communication between a Path Computation Client and a Path Computation Element, which includes topology learning functionalities. IS-IS and RIP are routing protocols that do not serve this purpose, and MPLS is a data forwarding method rather than a topology learning protocol.
