Difficulty: EasyRemote Access and Out-of-Band Management

Match each remote management protocol or access method on the left to its correct primary characteristic on the right.

  • SSH (Secure Shell)Provides encrypted command-line access over network connections.
  • TelnetProvides unencrypted, cleartext command-line access.
  • Cellular Out-of-Band ModemProvides alternative remote reachability when primary WAN connections fail.
  • RDP (Remote Desktop Protocol)Provides a graphical user interface session to remote systems.

Answer

SSH matches with encrypted command-line access; Telnet matches with unencrypted cleartext access; Cellular Out-of-Band Modem matches with alternative connectivity during primary connection failure; RDP matches with graphical user interface sessions.
Each management solution is paired directly with its core operational distinction: SSH offers encrypted command-line sessions, Telnet provides unencrypted command-line sessions, Cellular Out-of-Band modems deliver secondary connectivity during primary network failures, and RDP supplies graphical desktop interface sessions.

Step-by-Step Solution

1
Identify the primary encrypted command-line remote access method.
SSH provides secure, encrypted terminal access over network connections.
SSH encrypts session communications to protect against eavesdropping.
2
Identify the legacy unencrypted terminal access protocol.
Telnet transmits command-line traffic in unencrypted plain text.
Telnet lacks native encryption capabilities.
3
Identify the alternative access mechanism used during primary network outage.
Cellular Out-of-Band Modem provides backup network access independent of standard WAN links.
Out-of-band cellular connections bypass local infrastructure failures.
4
Identify the graphical desktop remote access protocol.
RDP enables full graphical user interface remote management.
RDP streams the graphical desktop environment to remote administrators.
