CompTIA Server+ SK0-005 Practice Question
An enterprise maintains a dedicated management VLAN for lights-out access to its production servers. Late on a Friday night, a 2U rack server in a remote branch becomes completely unresponsive: the operating system has crashed, and the network team has disabled the trunk that carries the server's data NICs to prevent it from causing a broadcast storm. No personnel are on-site. You must remotely restore the system by performing these steps:
- Hard power-cycle the chassis.
- Open a console that shows POST messages and BIOS setup.
- Attach a bootable ISO image from your laptop so you can reload the firmware and operating system.
Which built-in subsystem will let you accomplish all three tasks over the isolated management network, even though the host OS and data interfaces are offline?
Access the motherboard's baseboard management controller (BMC) through its dedicated IPMI port.
Send a Wake-on-LAN magic packet to one port of the server's bonded data NICs.
Issue SNMP write commands to the server's in-band management agent to reboot the host.
Establish a Windows Remote Desktop Protocol session using the server's last known IP address.
