Correct answer & explanation
✓

Defense in depth for physical security involves multiple layers: external perimeter controls (fencing, bollards, lighting), building entrance controls (guards, access badges, mantraps), and internal controls (server room biometric readers, equipment locks). Together they create overlapping barriers.
