A technician needs to install an additional PCI NIC without powering down the server. Which of the following BEST describes the technology the board must support?

"Hot install" is not a standard industry term for this functionality; while it implies installing while running, "hot plug" is the correct technical term.

"Hot add" is a term often used in virtualization environments for adding resources like CPU or memory to a running virtual machine, but "hot plug" is the specific term for physical PCI devices.

Plug and Play (PnP) is a technology that allows the operating system to automatically detect and configure hardware devices without manual intervention, but it does not inherently imply the ability to add or remove devices while the system is powered on.

Hot plug technology specifically refers to the ability to add or remove components, such as a PCI NIC, from a running system without powering it down or causing disruption, ensuring continuous operation.
