Answer:

b. The Hello timer as configured on the root switch.

Explanation:

There are differrent timers in a switch. The root switch is the only forwarding switch in a network, while non root switches blocks traffic to  prevent looping of BPDUs in the network. Since the root switch is the only forwarding switch, all timing configuration comes from or is based on the configuration in the root.

The hello timer is no exception as the nonroot switch only sends 802.1D DTP hello BPDU messages forwarded to it by the root switch and its frequency depends on the root switch hello timer.

Checkpoint 7.61 Write the prototype for a function named showSeatingChart that will accept the following two-dimensional array a
Kobotan [32]

Answer:

void showSeatingChart(const string [][COLS], int);

Explanation:

void showSeatingChart(const string [][COLS], int);

The above function showSeatingChart() will display the 2D array of seating chart.

The return type of this function is void because it does not need to retun anything.

The parameter of the function is a 2D array which is seatingChart[ROWS][COLS].

The type of this 2D array is string that means it is a 2D array of string. It will contain string elements.

To declare a prototype of a function, there should be a semi-colon (;) at the end of declaration.

The definition of the function should be given outside main() function and declaration of the function should be above the main() function or at the beginning of the program with declaration of constant variables.

Answer:

count = 0

while count != 8:

   height = float(input("Enter height of the rider: "))

   if height >= 140:

       print("You are allowed to ride")

       count += 1

   else:

       if height >= 120:

           answer = input("Is the rider with an adult (yes/no): ")

           if answer == "yes":

               print("You are allowed to ride")

               count += 1

           else:

               print("You are not allowed to ride")

       else:

           print("You are not allowed to ride")

Explanation:

Initialize the count as 0, it will count the number of people allowed to ride

Create a while loop that iterates while count is not equal to 8

Inside the loop, ask the user for the height. If the height is greater than or equal to 140, print "You are allowed to ride" and increment the count by 1. Otherwise, check if the height is greater than or equal to 120. If it is not, print "You are not allowed to ride". If it is, ask if the rider is with an adult or not. If it is not, print "You are not allowed to ride". If it is print "You are allowed to ride" and increment the count by 1.
