Q: 3
An administrator needs to perform bare-metal maintenance on a server in a remote datacenter.
Which of the following should the administrator use to access the server’s console?

I don’t think it’s A. Option D trips up a lot of people, I'd pick RDP for remote console tasks here.
Nah, it’s not B-VNC only works once the OS is running. For bare-metal (like BIOS or pre-boot) remote console, A (IP KVM) is what actually lets you interact before the OS loads. Got tripped by that a couple times in practice sets. Let me know if you think there’s a use case for anything but A.
D seems right to me since RDP lets you remote into the server, even for maintenance. Maybe I'm missing something about "bare-metal," but I thought RDP could handle a lot of that if the OS is online. Am I off here?
Definitely A for bare-metal. The other options rely on the OS being up, but an IP KVM gets you direct console access.
Option D
Maybe A lets you get to the server even if there's no OS or it's crashed. The real trap is picking VNC or RDP, but those only work when the OS is running. Seen similar questions in practice sets.
C or A? If the admin was on-site C would make sense, but for remote pre-OS access I'm thinking A is correct.
Every CompTIA question makes remote management sound trickier than it is. A imo, since IP KVM is the only one here that'll let you touch BIOS or pre-OS screens from afar, nothing else works at bare metal.
Wouldn’t VNC require a working OS already? How would you use it for BIOS access?
Why wouldn't VNC (B) work here if you had a service running?
Be respectful. No spam.
