A network administrator is setting up a web server for a small advertising office and is concerned with data availability. The administrator wishes to implement disk fault tolerance using the minimum number of disks required. Which RAID level should the administrator choose?
A) RAID 0B) RAID 1
C) RAID 5
D) RAID 6

RAID 1 level should be  choosed by the administrator.

B) RAID 1

Explanation:

RAID 1 is commonly utilized with a couple of plates, however, it should be possible with additional, and would indistinguishably reflect/duplicate the information similarly over all the drives in the exhibit. RAID 1  requires at least two physical drives, as information is composed at the same time to two spots.

The drives are basically identical representations of one another, so on the off chance that one drive comes up short, the other one can dominate and give access to the information that is put away on that drive. The purpose of RAID 1 is principally for repetition, as you can totally lose a drive, yet at the same time keep awake and running off the extra drive(s).

Likewise, at least two circles are required for RAID 1 equipment usage. With programming RAID 1, rather than two physical circles, information can be reflected between volumes on a solitary plate.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
