Match each remote access or out-of-band management technology on the left with the enterprise scenario on the right for which it is the most appropriate management solution.
- Cellular Out-of-Band (OOB) Modem connected to a Terminal ServerManaging network switch console ports during a complete primary WAN provider circuit outage at a remote branch site.
- IP-KVM Switch with Virtual Media capabilitiesRemotely mounting a local ISO image to re-install an operating system on a bare-metal server whose host network interface card is disabled.
- Baseboard Management Controller (BMC) via IPMI / lights-out managementMonitoring server motherboard temperature sensors and adjusting hardware power states prior to operating system initialization.
- Switched Smart Power Distribution Unit (PDU)Hard power-cycling an unresponsive core switch whose management control plane and network interfaces have completely locked up.
- In-Band SSH over IPsec Remote Access VPNExecuting routine administrative CLI commands on an operational switch across a secure encrypted tunnel during normal network operations.
Cevap
The technology items correctly align with their deployment scenarios based on whether access relies on the production network path (in-band) or dedicated non-production hardware paths (out-of-band serial, power, or lights-out management interfaces).
Each management technology addresses specific operational conditions: Cellular OOB modems with terminal servers restore console access during primary link loss; IP-KVM switches enable keyboard/video/mouse control and remote ISO mounting without an OS; IPMI/BMC provides low-level system health metrics directly from the motherboard micro-controller; switched PDUs enable remote AC outlet power cycling when device control planes lock up; and SSH over IPsec VPN provides secure, encrypted in-band CLI access over operational networks.
