The method that effectively prevents a rainbow table attack is using salted hashes for password storage.

Here's a step-by-step explanation:

1. A rainbow table attack is a type of hacking where the attacker uses a precomputed table for reversing cryptographic hash functions, usually for cracking password hashes.

2. Salting is a method that adds an additional value to the end of the password, creating a salted hash, before it's hashed again. This means even if two users have the same password, their hashed passwords will be different due to the unique salt.

3. When an attacker tries to use rainbow tables in a salted system, they would need a new rainbow table for each possible salt value, which is computationally very expensive and practically infeasible.

4. Therefore, using salted hashes for password storage is an effective method to prevent rainbow table attacks.

Note: While the other methods mentioned (account lockout policies, requiring complex password patterns, and encrypting passwords with RSA) can enhance security, they do not specifically prevent rainbow table attacks.
