Why each option
The question asks to identify two Ethernet protocols that enable Command Line Interface (CLI) access.
SNMP (Simple Network Management Protocol) is used for monitoring and managing network devices, not for interactive CLI access.
Telnet is an application-layer protocol used to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection over an IP network, commonly used for CLI access. However, it transmits data in plaintext, making it insecure.
UDP (User Datagram Protocol) is a transport layer protocol, not an application layer protocol used for interactive CLI sessions; it provides connectionless communication.
SSH (Secure Shell) is a cryptographic network protocol for operating network services securely over an unsecured network, providing a secure channel over an unsecured network by using strong encryption. It is widely used for secure remote command-line access.
HTTP (Hypertext Transfer Protocol) is primarily used for web browsing and accessing web-based graphical user interfaces (GUIs), not for direct command-line interface access.
