Consider the following code segment. int[][] multi = new int[4][4];

for (int rows = 0; rows < 4; rows++)

{

for (int cols = 0; cols < 4; cols++)

{

if (cols == 0)

{

multi[rows][cols] = 0;

}

else if (cols == 1)

{

multi[rows][cols] = 1;

}

else if (cols == 2)

{

multi[rows][cols] = 2;

}

if ((rows % 2 == 0) && (cols % 2 == 0))

{

if ((rows >= 2) && (cols <= 2))

{

multi[rows][cols] = 9;

}

}

}

}

As a result of executing the code segment, how many elements in the two-dimensional (2D) array multi will store the value 9 ?

A 0

B 1

C 2

D 4

E 6

One of your customers wants you to build a personal server that he can use in his home. one of his concerns is making sure he has at least one backup of their data stored on the server in the event that a disk fails. you have decided to back up his data using raid. since this server is for personal use only, the customer wants to keep costs down. therefore, he would like to keep the number of drives to a minimum. which of the following raid systems would best meet the customer's specifications? a. raid 0 b. raid 1 c. raid 5 d. raid 10

1. you have a small business that is divided into 3 departments: accounting, sales, and administration. these departments have the following number of devices (computers, printers, etc.): accounting-31, sales-28, and administration-13. using a class c private network, subnet the network so that each department will have their own subnet. you must show/explain how you arrived at your conclusion and also show the following: all available device addresses for each department, the broadcast address for each department, and the network address for each department. also, determine how many "wasted" (not usable) addresses resulted from your subnetting (enumerate them).
