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?
Establish a Windows Remote Desktop Protocol session using the server's last known IP address.
Issue SNMP write commands to the server's in-band management agent to reboot the host.
Send a Wake-on-LAN magic packet to one port of the server's bonded data NICs.
Access the motherboard's baseboard management controller (BMC) through its dedicated IPMI port.
