You are designing a backup solution for an EMC NetWorker customer. Based on EMC best
practices, how many CPU cycles are needed by the storage node when backing up clients over
the network to local tape drives at a rate of 100 MB/s?
A.
0.2 Hz
B.
0.5 Hz
C.
1.2 GHz
D.
2.4 GHz
Correct answer is B:- .5Ghz
Exp:- 5MHz of CPU capacity per 1MB/Sec of data movement in and out of a NetWorker storage node.

It is mentioned a rate of 100MB/s so it is 500Mhz in and 500Hz out,so 1.2Ghz is the closest to the 1Ghz required.
Also Answer B is not in Gig but in Hertz (.5Hz not .5GHz)

the answer is 0.5 ghs + 0.5 ghz = 1 ghz.. remeber it is 5MHz for every 1MB/s
