What type of password cracking attack will always be successful?

A.
Brute Force

B.
Dictionary

C.
Hybrid

D.
Rainbow Table

Explanation:
Answer A is correct; brute force attacks are always successful, given enough time.

Incorrect Answers and Explanations: B, C, and D: Answers B, C, and D are incorrect. Dictionary attacks will only crack passwords that exist in a dictionary or word list. Hybrid attacks append, prepend, or alter characters in words from a dictionary. A rainbow table uses precomputed hashes. Not all rainbow tables are complete, and rainbow tables are less effective against salted hashes.
