Which of the following hardware devices will you connect to the server in order to resist power outages or
power fluctuations?

A. Hard disk




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
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.
