What's the main piece of information you look for in an e-mail message you're investigating??

2. An evil twin attack that broadcasts a legitimate SSID for an unauthorized network is an example of what category of threat? A

avanturin [10]

Answer:

A. Spoofing

Explanation:

Spoofing is the act of disguising a communication from an unknown source as being from a known, trusted source. Spoofing can apply to emails, phone calls, and websites, or can be more technical, such as a computer spoofing an IP address, Address Resolution Protocol (ARP), or Domain Name System (DNS) server.

IP spoofing involves an attacker trying to gain unauthorised access to a system by sending messages with a fake or "spoofed" IP address to make it look like the message came from a trusted source, such as one on the same internal computer network, for example.

Email spoofing often involves things like requests for personal data or financial transactions. The emails appear to be from trusted senders such as customers, coworkers, or managers but they are actually from cyber criminals who deliberately disguise themselves to gain your trust and your help with the action they want you to take

Fofino [41]

Answer:

Two advantages of the agile methods are:

The agile method require less documentation process as compared to waterfall model and saves maximum time and money. It basically reduces the efforts and the amount of work.
In agile method, there is always high customer satisfaction present. In agile method, it is easy to modify in the data as compared to the waterfall model. The customers and developers always interact with each other as the interaction is very important for the good results in the project.

Two disadvantages of the agile methods are:

For the large and complex projects, sometimes it is difficult to determine the requirements in the software development as projects are easily go off track.
There is less predictability and the projects are easily messed up if the projects requirement are not clear by the customer end.

Write a program that reads numbers from scanf (keyboard) and then sums them, stopping when 0 has been entered. Construct three v

almond37 [142]

Answer:

For loop Version:

#include <stdio.h>

int main()

{

int number, sum = 0;

printf("Enter a positive integer: ");

scanf("%d", &number);

for (int i = 0; i <= number; i++) {

if(number == 0)

break;

sum += number;

printf("Enter a positive integer: ");

scanf("%d", &number);

}

printf("Sum is: %d", sum);

return 0;

}

While Loop Version:

#include <stdio.h>

int main()

{

int number, sum = 0, i = 0;

printf("Enter a positive integer: ");

scanf("%d", &number);

while (number != 0) {

sum += number;

printf("Enter a positive integer: ");

scanf("%d", &number);

}

printf("Sum is: %d", sum);

return 0;

}

Do-while Loop Version:

#include <stdio.h>

int main()

{

int number, sum = 0, i = 0;

do {

printf("Enter a positive integer: ");

scanf("%d", &number);

sum += number;

} while (number != 0);

printf("Sum is: %d", sum);

return 0;

}

Explanation:

- Initialize the variables

- Ask the user for the numbers until the user enters 0

- Calculate and print the sum

What is the purpose behind the Three Phase Commit? It improves upon the two phased commit by requiring that locks be acquired at

Ray Of Light [21]

The answer is a) It improves upon the two-phased commit by requiring that locks be acquired at the start of a transaction.

Reason: The 3PC is an extension or you can say developed from 2PC that avoids blocking of an operation. It just ensures that first n sites have intended to commit a transaction that means it acquires commits or locks before the start of any transaction to avoid any blocking.

Option b) is wrong as it does not allow coordination, it just let all the other sites do their transaction if any other site is blocked, so no coordination is there between sites that they will wait till their coordinator is corrected.

Option c) is wrong as lock operations are shared between other connections as when their coordinator fails, the new coordinator agrees to the old coordinator that they had shared locks before and they can start their transaction.

Option d) is wrong as option a) is correct.
