Devices including routers and switches are commonly accessed using what two resources?

• A. SSH or HTTPS
• B. Telnet or FTP
• C. SNMP or Telnet
• D. HTTP or FTP

Answer: (A)

Secure remote management of routers and switches typically uses two main resources: SSH for secure command-line access and HTTPS for a secure web-based interface. SSH provides encrypted, authenticated access to the device’s CLI, so your login credentials and configuration commands are protected in transit. HTTPS offers an encrypted web GUI, allowing configuration through a browser with TLS protection. Other options like Telnet or FTP transmit data in plaintext, including credentials, making them insecure. HTTP by itself isn’t encrypted, so it doesn’t protect sensitive information. SNMP is mainly for monitoring and retrieving status rather than interactive device configuration. Using SSH and HTTPS together gives secure options for both CLI and GUI management.
