Answer:
d. Port mirror
Explanation:
Port mirroring is a method to monitor network traffic and it is used in the Intrusion Detection Systems. It is also called Switched Port Analyzer and is used to analyse the network errors. This technique basically copies the network packets and sends or transmits these copied packed from one port to another in a network device such as a switch. This means that this technique is used to copy the network packets from one switch port and send the copy of these packets to another port where these packets are monitored. This is how it analyses the network errors and incoming traffic for irregular behavior and also this can be done without affecting the normal operation of the switch and other network processes. It is simple, inexpensive and easy to establish and use. The most important advantage of using mirrored ports is that it catches the traffic on several ports at once or can capture all of the network traffic.
Answer:
a. grep 'b[au]nk$' myLine
Explanation:
grep is a command used for searching a specified pattern in a given text.
Our goal is to match the character sequence - bank or bunk at the end of line in a given line referenced by myLine.
The regular expression for the specified match criterion is:
b[au]nk$
The second character can be either a or u.
$ indicates match at end of line.
So the overall grep command is :
grep 'b[au]nk$' myLine
Answer:
Hi there! Pseudocode is the process of writing out the high-level structure of the program in simple English terms which acts as a blueprint of how the program will work. The pseudocode for this question is written below.
Explanation:
Prompt user for input 1
Validate input 1
Prompt user for input 2
Validate input 2
Prompt user for input 3
Validate input 3
Perform checks:
If
1 and 2 equals 3
Or
1 and 3 equals 2
Or
2 and 3 equals 1
Display message to user
Answer:
Explanation:
#include <iostream>
using namespace std;
//This is the function in the next line
double MilesToLaps(double userMiles) {
double Laps;
Laps = userMiles * 4;
return Laps
}
//This is the main fucnction
int main(){
double Miles, FinLap;
cout << "Enter the number of miles " << endl;
cin>>Miles;
FinLap = MilesToLaps(Miles);
cout << "The number of laps ran is: "<<setprecision(2)<<Finlap<<endI;
}
