Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 99

Which protocol is used for communication between the PCE and PCC?

Answer options

• A. POP
• B. CEF
• C. PCEP
• D. ICMP

Correct answer: C

Explanation

The correct answer is C, PCEP, which is specifically designed for communication between a Path Computation Element (PCE) and a Path Computation Client (PCC). Options A, B, and D are incorrect because POP is a mail protocol, CEF is related to Cisco's Express Forwarding, and ICMP is used for network diagnostics, none of which are relevant to PCE and PCC communication.
