Exam SK0-005 topic 1 question 8 discussion

I disagree. If a system is bare metal, there is no way to access the BIOS and Hardware without a crash cart, KVM, console, or remote management (iLO, etc). Since only one of those options (ip KVM or iLO) can be done remotely, that would be the correct answer. RDP would allow you to manage the operating system running on the server, but not the bare metal system itself.

First off, RDP is only a Windows based protocol, not all servers use Windows as the OS. At one time, all servers were bare-metal servers. Servers were kept on-premises and often belonged to the organization using and operating them. In computer networking, a bare-metal server is a physical computer server that is used by one consumer, or tenant, only. Each server offered for rental is a distinct physical piece of hardware that is a functional server on its own. They are not virtual servers running in multiple pieces of shared hardware. With that being the definition of On-Premises Server, you could use A. IP KVM, or C. A crash cart to gain access to the server. The question is vague enough not to be able to correctly determine by not knowing the need. Is the server in the same room? Do they have a OOB network set up? If you can access the server via IP KVM, why wouldn't you opt to?. Make sure you do your Backups/ Testing beforehand.

An administrator needs to perform bare-metal maintenance on a server "IN" a remote datacenter.

I concur with A. 49tiktok has the correct reasoning as to why

A: This way, the OS on the server does not matter and you have access to BIOS and other functions like RAID configuration.

KVM vendors have responded to the need for a KVM switch that can be accessed over the network. The switch is like the one you saw earlier with one difference—it can be reached through the network. This means it is accessible not only from a workstation in the next room, but from anywhere. In this particular implementation (it can be done several ways), each server has a small device between it and the KVM switch that accepts the serial and keyboard/mouse connections.

KVM-over-IP switches are the remote access version of local KVM (keyboard/video/mouse) devices. They allow administrators to control a remote system by sending keyboard and mouse signals over the network and displaying the remote system’s video output on the administrator’s local machine via a web browser. Administrators can perform almost any function on the remote system as long as it’s powered on and connected to the network.
