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.
Answer: Lattice-based, non-discretionary
Explanation: Lattice-based access control is a form of non-discretionary access control in which users are assigned a matrix of authorizations for particular areas of access. Lattice-based access control are usually used to restrict or define the level of authorization granted to a subject which may be an individual, organization or group or the that given to the object which may include applications and computers.It utilizes a non-discretionary approach whereby the defined access is uniformly enforced across all subjects and objects within the confines of an information system.
Answer:
30
Explanation:
Java - Using a method, how do I "write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. Your program must define and call the following method that returns the number of times the input character appears in the input string.
public static int countCharacters(char userChar, String userString)"
Answer:
Following are the program in C++ language
#include <iostream> // header file
using namespace std; // namespace
int main() // main function
{
int number=0; // variable declaration
while(number>-1) // iterating the while loop
{
cout<<"body"<<endl; // dsiplay the statement
cin>>number; // Read the value by the user
}
cout<<endl<<"Done";// dsiplay the statement
return 0;
}
Output:
body
5
body
45
body
-8
Done
Explanation:
Following are the description of the statement
- Declared a variable "number" of int type and initialized with 0 to them
- iterating the while loop. In this loop print the message "body" and Read the value by the user in the "number" variable. This loop will be executed repeatedly until the user do not read the negative value.
- After the execution of the while loop, it prints the message "Done".
