    Question

    Which protocol is most commonly used for securing remote

    access to network devices?
    A Telnet Correct Answer Incorrect Answer
    B SSH (Secure Shell) Correct Answer Incorrect Answer
    C FTP (File Transfer Protocol) Correct Answer Incorrect Answer
    D SNMP (Simple Network Management Protocol) Correct Answer Incorrect Answer
    E ICMP (Internet Control Message Protocol) Correct Answer Incorrect Answer

    Solution

    SSH provides a secure channel over an unsecured network for remote management of devices. Unlike Telnet, which transmits data in plaintext, SSH uses encryption to protect credentials and communication, ensuring confidentiality and integrity. SSH is widely used for securely managing servers, routers, and switches, offering authentication mechanisms and data encryption to prevent eavesdropping or attacks. ________________________________________ Why Other Options Are Incorrect? 1. Telnet: Lacks encryption, making it insecure for modern use. 2. FTP: Used for file transfers, not remote management. 3. SNMP: Designed for network monitoring, not direct device access. 4. ICMP: Used for diagnostics like ping, not device management.
