Match each out-of-band management technology on the left to the enterprise infrastructure recovery scenario on the right for which it serves as the most appropriate solution.
- IP-KVM Switch with Virtual Media MappingA bare-metal server experienced host OS corruption, requiring a technician to remotely mount a localized bootable installation ISO image and navigate BIOS settings.
- Switched Smart Power Distribution Unit (PDU)A hypervisor host has completely frozen and stopped responding to all network pings, requiring a hard power cycle and real-time power consumption verification.
- Cellular Out-of-Band (OOB) Gateway with VPNThe primary ISP fiber transport to a branch office was severed, cutting off all standard in-band management traffic to internal routers and switches.
- Dedicated Serial Terminal Server (Console Server)A core network switch lost its running configuration during a power disruption and is stuck at the command line bootloader prompt accessible only via RS-232 serial interfaces.
Answer
IP-KVM Switch with Virtual Media Mapping matches OS reinstallation via remotely mounted ISO images. Switched Smart PDU matches remote power cycling and current monitoring of frozen host servers. Cellular OOB Gateway matches alternate transport during primary fiber link cuts. Dedicated Serial Terminal Server matches console command-line recovery of switches stuck at bootloader prompts.
Each management method addresses a specific layer of failure. Virtual media on IP-KVM enables full remote system installation by presenting local images to remote bare-metal hardware. Smart PDUs provide direct control over power outlets to recover unresponsive hardware via hard power cycling. Cellular OOB gateways bypass severed terrestrial infrastructure using cellular networks to restore connectivity to management devices. Serial terminal servers consolidate console cables into a centralized platform for low-level switch and router recovery.
