Question
Which access control model is more flexible and scalable between Mandatory Access Control (MAC)l and Discretionary Access Control (DAC)?
Options
- AMAC, for compartmentalization and scalability by adding more compartments
- BDAC, for centralized decision-making, quick responses, and scalability by reducing required
- CDAC, for enabling individual administrators to make decisions and achieve scalability and
- DMAC, for its scalability and flexibility by adding more labels

Explanation
Discretionary Access Control (DAC) is more flexible because resource owners or individual administrators can grant or revoke permissions on their own resources without requiring central authority approval. This decentralized decision-making makes it easier to scale across large, dynamic environments. Mandatory Access Control (MAC), by contrast, enforces rigid, centrally-defined labels and classifications (e.g., Top Secret, Secret). While MAC is highly secure, it is inflexible-changes require administrative overhead-making DAC the winner for flexibility and scalability.
