Answer options

• A. REST
• B. PCEP
• C. NETCONF
• D. SNMP

Correct answer: B

Explanation

The correct answer is B, PCEP, as it is specifically designed for the communication of path computation requests and responses between a controller and network elements. The other options, while useful for different functions, do not serve the purpose of tunnel discovery in the context of WANs.
