Question
A company wants to remotely manage Cisco switches and routers over a secure connection. What protocol should they use?
A. Telnet
B. SSH
C. HTTP
D. SNMP
E. RADIUS
Answer
B. SSH
Explanation
SSH provides encrypted remote access to network devices, unlike Telnet, which transmits data in plaintext.
The protocol that should be used for secure remote management of Cisco switches and routers is SSH (Secure Shell).
- SSH encrypts all data transmitted between the client and the network device, including usernames and passwords, protecting against eavesdropping and man-in-the-middle attacks.
- Unlike Telnet, which sends data in plaintext and is vulnerable to interception, SSH ensures confidentiality and integrity of management sessions.
- SSH uses public key cryptography for authentication and operates over TCP port 22 by default.
- Cisco devices support SSH for remote management, and configuring SSH involves setting a hostname, domain name, generating RSA keys, and enabling SSH on VTY lines.
SSH is the industry standard for secure, encrypted remote access to Cisco network devices, providing robust protection for management traffic.
