We all know that there are 26 letters available in the alphabet and there are just 5 even numbers between 0 and 9. We are now given the situation of how many passwords can we make out of the criteria of having 5 letters that cannot be repeated and 4 even digits from 0-9. We cannot repeat the numbers and letters, thus our password will look something like this, LLLLLNNNN, where L is a letter and N is a number. Let us note that we cannot use the characters and digits more than once.This is how we will solve the probable number of passwords.
26 x 25 x 24 x 23 x 22 x 5 x 4 x 3 x 2
When we compute this formula, we will have the total number of possible passwords:
947,232,000.00
There are 947,232,000 possible passwords based on the given criteria.
Answer:
A) True

<span> In a network that uses WPA2-PSK encryption you can bypass the encryption by using the weakness in the WPA2-PSK system and that is the following:the encrypted password is shared in what is known as the 4-way handshake. </span> When a client authenticates to the access point, the client and
the AP go through a 4-step process of authentication.
The equivalent of film speed in a digital camera is going to be sensitivity. This will make the correct answer B.
