Explanation

PuTTY is a terminal emulator application that specifically supports Telnet and SSH as its primary protocols for establishing remote CLI sessions to network devices like switches - making C and E correct.

Why the distractors are wrong:

• SNMP (A) is used for monitoring and managing network devices by polling MIB data, not for interactive terminal sessions.
• HTTP (B) is a web protocol used by browsers to access GUI-based management interfaces, not terminal emulators like PuTTY.
• RMON (D) is a network monitoring standard that extends SNMP for traffic analysis - it has nothing to do with remote terminal access.

Memory tip: Think of PuTTY's icon - it's a terminal window. If the protocol gives you a command-line shell on a remote device, PuTTY can use it. Between Telnet and SSH, remember SSH = Secure Shell (encrypted, preferred), while Telnet sends everything in plaintext - both are valid PuTTY protocols, but SSH is always the better choice in production.
