fsas3alG
Except option C, the choices are forms of common words that might be found during a dictionary attack.
mike is a name and would be easily detected. elppa is simply apple spelled backward, and dayorange
combines two dictionary words. Crack and other utilities can easily see through these "sneaky"
techniques. Option C is simply a random string of characters that a dictionary attack would not uncover.

Password Attacks Correct Answer: Which one of the following passwords is least likely to be
compromised during a dictionary attack?
A elppa
B dayorange
C fsas3alG
D mike
Salting
Salting passwords adds a random value to the password prior to hashing, making it impractical to
construct a rainbow table of all possible values.
