Certified Network Defender (CND) — Question 96

Which of the following is a session layer protocol?

Answer options

• A. RPC
• B. SLP
• C. RDP
• D. ICMP

Correct answer: A

Explanation

The correct answer is A, RPC (Remote Procedure Call), which is designed to facilitate communication between different processes over a network at the session layer. The other options, SLP (Service Location Protocol), RDP (Remote Desktop Protocol), and ICMP (Internet Control Message Protocol), do not operate at the session layer; SLP is used for service discovery, RDP is for remote desktop services, and ICMP is used for network diagnostics.
