Which of the following statements regarding the last two octets of the LDP identifier is true?

Answer options

• A. It is always a random 16-bit number.
• B. It is always zero for per-interface label space.
• C. It is always non-zero.
• D. It is always zero for per-platform label space.
• E. It is always non-zero for per-platform label space.

Correct answer: D

Explanation

The correct answer is D because the last two octets of the LDP identifier are set to zero when using a per-platform label space. Options A and C are incorrect as they misrepresent the nature of the identifier, while B and E do not accurately describe the behavior of the LDP identifier in relation to per-interface and per-platform label spaces.
