Answer:
The program to this question as follows:
Program:
//header file iostream
#include<iostream> //including file for use basic function 
//using name space
using namespace std;
//main method 
int main() //defining main method
{
    int a[3][3]; //defining two dimension array 
    int x,y,sum=0; //defining variables
    cout<<"Enter array elements: "<<endl; //message
    for(x=0;x<3;x++) // for row
    {
        for(y=0;y<3;y++) //for column
        {
           cin>>a[x][y]; //input values from user.
        }
        
    }
    //loop for calculting sum.
    for(x=0;x<3;x++) 
    {
        for(y=0;y<3;y++)
        {
        sum=sum+a[x][y];//add all elements
        }
        
    }
    cout<<"Sum: "<<sum; //print sum.
    return 0;
}
Output:
Enter array elements:  
1
2
3
4
5
6
7
8
9
Sum: 45
Explanation:
In the above C++ programming language code first, a header file is included then the main method is declared, inside a main method 2D array that is "a[][]", and an integer variable is defined that are "i, j, and sum". In the next line for loop is used, this loop is used two times that can be described as follows:
- The first time it is used for inserting elements from user ends.  
 - The second time, it uses the sum variable to add all array elements. and in the last print function that is "cout" is used for print sum variable value.

Answer:
The answer is "Pass the cable into the ceiling instead of over the floor".
Explanation:
Network access explains the complex process of link different parts of the network with each other, e.g. while using switches, routers, and access points, and whether, that system works.
- To replace the cable with a pair cable graded in plenum, covered, twisted.
 - We use the cable to pass through the ceiling rather than through the concrete, eliminating the issue and stopping it from occurring again.
