Explanation

Multilevel security (MLS) mode allows a system to process data at multiple classification levels simultaneously, and users do NOT need clearance for all levels - they only access information at or below their own clearance level, combined with need-to-know controls. Dedicated mode (D) requires all users to have the clearance and need-to-know for ALL data on the system. System-high mode (C) requires all users to have clearance for the highest level but not necessarily need-to-know for all data. Compartmented mode (A) requires clearance for the highest level plus formal access approval for compartments.
