Question options:
a. RAID 0
b. RAID 1
c. RAID 5
d. RAID 6
e. RAID 10
Answer:
d. RAID 6
Explanation:
RAID is Redundant Array of Inexpensive/Independent Disks. RAID combines low cost physical hard disk drives in one hard disk drive. RAID is used to achieve data redundancy(data backup but with synchronization) or improved performance or both.
To get what the director requires he would need to use RAID 6. RAID 6 is RAID level optimized to achieve data redundancy but with slow performance.
Illustrate why Sally's slide meets or does not meet professional expectations?
Describe all the things Sally can improve on one of her slides?
Suggest some ways Sally can learn more PowerPoint skills.
The correct answer to this open question is the following.
Unfortunately, you did not provide any context or background about the situation of Sally and the problem with her slides. We do not know it, just you.
However, trying to be of help, we can comment on the following general terms.
When someone does not meet professional expectations, this means that this individual did not prepare her presentation, lacked technical skills, did not included proper sources, or missed the proper visual aids to make the presentation more attractive and dynamic.
What Sally can improve about her slides is the following.
She can design a better structure for the presentation to have more congruence.
Sally has to clearly establish the goal or goals for her presentation.
She has to add many visuals instead of plain text. This way she can better capture the interest of her audience.
If she can use more vivid colors instead of pale or dark ones, that would be best.
No paragraphs unless necessary. She better uses bullet points.
Take care of the tone of her voice. During her practice, she can record her vice to check how it sounds.

g 1-1 Which network model layer provides information about the physical dimensions of a network connector like an RJ45
Answer:
Physical layer
Explanation:
OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;
1. Physical Layer
2. Data link Layer
3. Network Layer
4. Transport Layer
5. Session Layer
6. Presentation Layer
7. Application Layer
Each layer has its unique functionality which is responsible for the proper functioning of the communication services.
In the OSI model, the physical layer is the first and lowest layer. Just like its name physical, it addresses and provides information about the physical characteristics such as type of connector, cable type, length of cable, etc., of a network.
This ultimately implies that, the physical layer of the network (OSI) model layer provides information about the physical dimensions of a network connector such as a RJ45. A RJ45 is used for connecting a CAT-5 or CAT-6 cable to a networking device.

Explanation:
Write a recursive function that returns 1 if an array of size n is in sorted order and 0 otherwise. Note: If array a stores 3, 6, 7, 7, 12, then isSorted(a, 5) should return 1 . If array b stores 3, 4, 9, 8, then isSorted(b, 4) should return 0.
Answer:
The function in C++ is as follows:
int isSorted(int ar[], int n){
if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){
return 1;}
if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){
return 0;}
return isSorted(ar, n - 1);}
Explanation:
This defines the function
int isSorted(int ar[], int n){
This represents the base case; n = 1 or 0 will return 1 (i.e. the array is sorted)
if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){
return 1;}
This checks if the current element is less than the previous array element; If yes, the array is not sorted
if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){
return 0;}
This calls the function, recursively
return isSorted(ar, n - 1);
}
In C language
In a main function declare an array of 1000 ints. Fill up the array with random numbers that represent the rolls of a die.
That means values from 1 to 6. Write a loop that will count how many times each of the values appears in the array of 1000 die rolls.
Use an array of 6 elements to keep track of the counts, as opposed to 6 individual variables.
Print out how many times each value appears in the array. 1 occurs XXX times 2 occurs XXX times
Hint: If you find yourself repeating the same line of code you need to use a loop. If you declare several variables that are almost the same, maybe you need to use an array. count1, count2, count3, count4, … is wrong. Make an array and use the elements of the array as counters. Output the results using a loop with one printf statement. This gets more important when we are rolling 2 dice.
Answer:
The program in C is as follows:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(){
int dice [1000];
int count [6]={0};
srand(time(0));
for (int i = 0; i < 1000; i++) {
dice[i] = (rand() %(6)) + 1;
count[dice[i]-1]++;
}
for (int i = 0; i < 6; i++) {
printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");
printf("\n");
}
return 0;
}
Explanation:
This declares an array that hold each outcome
int dice [1000];
This declares an array that holds the count of each outcome
int count [6]={0};
This lets the program generate different random numbers
srand(time(0));
This loop is repeated 1000 times
for (int i = 0; i < 1000; i++) {
This generates an outcome between 1 and 6 (inclusive)
dice[i] = (rand() %(6)) + 1;
This counts the occurrence of each outcome
count[dice[i]-1]++; }
The following prints the occurrence of each outcome
for (int i = 0; i < 6; i++) {
printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");
printf("\n"); }
Write a simple nested loop example that sums the even and odd numbers between 5 and 15 and prints out the computation.
Answer:
for e in range(6, 15, 2):
for o in range(5, 15, 2):
calc = e+o
print(e, "+", o, "=", calc)
Explanation:
A recursive method may call other methods, including calling itself. Creating a recursive method can be accomplished in two steps. 1. Write the base case -- Every recursive method must have a case that returns a value or exits from the method without performing a recursive call. That case is called the base case. A programmer may write that part of the method first, and then lest. There may be multiple base cases.Complete the recursive method that returns the exponent of a given number. For e.g. given the number 5 and the exponent 3 (53) the method returns 125. Note: any number to the zero power is 1. Note: Do not code for the example. Your method must work for all given parameters! Use this as your method header: public static int raiseToPower(int base, int exponent)
Answer:
Explanation:
The following code is written in Java. It creates the raiseToPower method that takes in two int parameters. It then uses recursion to calculate the value of the first parameter raised to the power of the second parameter. Three test cases have been provided in the main method of the program and the output can be seen in the attached image below.
class Brainly {
public static void main(String[] args) {
System.out.println("Base 5, Exponent 3: " + raiseToPower(5,3));
System.out.println("Base 2, Exponent 7: " + raiseToPower(2,7));
System.out.println("Base 5, Exponent 9: " + raiseToPower(5,9));
}
public static int raiseToPower(int base, int exponent) {
if (exponent == 0) {
return 1;
} else if (exponent == 1) {
return base;
} else {
return (base * raiseToPower(base, exponent-1));
}
}
}

You have been told the WAN protocol in use allows multiple Layer 3 protocols and uses routers that use labels in the frame headers to make routing decisions. What WAN technology is in use
Answer:
The answer is "MPLS".
Explanation:
The MPLS stands for Multiprotocol Label Switching. This packet switching method facilitates the generation of easier personal backbones using a less physical channel, which sends information from one source to its destination with labels rather than IP addresses. Many of these WAN services are sold through huge companies. It is also a technology for data transfer that boosts speed and regulates network traffic flow. The information is directed with this technology via a label rather than needing complicated surveys at every stop in a route cache.
