Answer: B

Explanation:

In order to resist power outages or power fluctuations, you should connect UPS (Uninterruptible Power Supply) to the server.

UPS (Uninterruptible Power Supply) devices employ a large battery to provide power to a system in the event of a power outage. The amount of time it can continue to supply power to the system depends upon the size of the battery, and the power consumption. UPS is built into the system between the reader and the external power source. The reader is susceptible to power spikes (caused due to lightning strikes or generator variations). UPS keeps the readers running in case of a power failure and also protects them against unexpected power spikes. The UPS helps in keeping data, which may be in the random access memory (RAM) and not yet pushed up to the application, from being lost and the configuration is not wiped out.

Incorrect Answers:

A: A hard disk drive is a non-volatile storage device that stores digitally encoded data on rapidly rotating rigid platters with magnetic surfaces.

C: Virtual Hard Disk (VHD) is a file with a .vhd extension. This file acts as a separate hard disk. In the Windows 10 or Windows Server 2016 operating system, Virtual hard disks can be created and used on computers that are not virtual machines.

D: Random Access Memory (RAM) is a chip that comes embedded within a computer. It is loaded by an operating system while starting the computer and it also copies an application to be run on the computer, such as a word processor or database program. Whenever a new program is created by a user, the program is temporarily held by RAM and copied to the disk to save the data permanently.
