Explanation

Multi-factor authentication (MFA) directly prevents unauthorized access to cloud accounts - the primary vector for data breaches - by requiring a second proof of identity even when credentials are stolen or guessed. Frequent password rotation (A) is largely considered outdated guidance and doesn't stop credential theft in progress. Regular software patching (C) addresses vulnerabilities but doesn't authenticate who is accessing the environment. Continuous monitoring (D) detects breaches after they begin rather than preventing unauthorized access in the first place.

Memory tip: Think "MFA = the lock on the door." Patching fixes holes in the walls, monitoring watches the cameras, and rotation changes the key - but MFA is what stops the intruder at the entrance.
