Difficulty: EasyRemote Access and Out-of-Band Management

Match each remote access and out-of-band management technology on the left with its primary administrative function on the right.

  • SSH (Secure Shell)Provides encrypted command-line management over an operational IP network.
  • Cellular OOB ModemProvides alternative console access to remote hardware during a primary link failure.
  • Smart PDUAllows remote power cycling of unresponsive network hardware outlets.
  • IP-KVMProvides hardware-level graphical interface and BIOS access independent of the host OS.

Answer

SSH matches with providing encrypted command-line management over an operational IP network; Cellular OOB Modem matches with providing alternative console access during primary link failure; Smart PDU matches with allowing remote power cycling of unresponsive outlets; IP-KVM matches with providing hardware-level graphical interface and BIOS access independent of host OS.
Each management solution aligns directly with a specific operational role: SSH handles encrypted in-band command-line administration, cellular out-of-band modems maintain emergency administrative access when network links fail, Smart PDUs enable remote outlet power cycling, and IP-KVM provides remote BIOS and graphical user interface access independent of the host operating system.

Step-by-Step Solution

1
Identify in-band encrypted CLI management
SSH provides encrypted shell sessions across standard IP network infrastructure.
SSH is the standard protocol for secure in-band command line access.
2
Identify redundant console reachability method
A cellular out-of-band (OOB) modem bypasses primary ISP and network connections to reach serial consoles directly.
Out-of-band management requires an alternate path independent of the primary data network.
3
Identify remote power control hardware
Smart PDUs manage electrical distribution and allow individual outlet power resets remotely.
When a network appliance freezes completely, cycling power via a Smart PDU is often required.
4
Identify remote hardware display and input management
IP-KVM appliances capture monitor output and input signals at the motherboard level.
IP-KVM functions even when the host operating system is corrupted or turned off.
