Which of the following devices would be installed if an administrator wants to control a group of servers from a remote location?

A VLAN (Virtual Local Area Network) is a logical segmentation of a network and does not provide direct remote control over server hardware.

A standard KVM switch allows control of multiple servers from a single, local console, but it does not inherently provide remote access over a network.

An IP KVM (Keyboard, Video, Mouse) switch allows administrators to remotely control multiple servers over a standard IP network from any location. It virtualizes the physical KVM connection, enabling out-of-band management even if the server's operating system is not responsive.

RAID (Redundant Array of Independent Disks) is a data storage virtualization technology used for data redundancy and performance, not for remote server control.
