Certified Network Defender (CND) — Question 71

Which of the following is a presentation layer protocol?

Answer options

• A. TCP
• B. RPC
• C. BGP

Correct answer: B

Explanation

RPC (Remote Procedure Call) is a protocol that operates at the presentation layer, facilitating communication between client and server applications.
