Explanation

Legacy networking was built around a "trust everything inside the perimeter" model, which creates two critical security weaknesses. Slow containment (D) occurs because flat, unsegmented legacy networks allow threats to spread laterally unchecked - by the time an intrusion is detected, the attacker has already moved deep into the network, making isolation and response painfully slow. Large attack surface (E) results from legacy designs that assumed a fixed internal perimeter, but modern realities (cloud, remote workers, IoT, BYOD) have expanded that perimeter massively, leaving countless unmanaged entry points exposed.

The distractors don't hold up: network downtime (A) is an availability/reliability concern, not a security risk unique to legacy architecture. User vulnerability (B) stems from human behavior and training gaps - it exists regardless of network design. Access points (C) are physical/wireless infrastructure components; their mere existence isn't a risk created by legacy approaches, only poor configuration of them is.

Memory tip: Think "Legacy leaves you SLOW and SPREAD" - Slow containment and a Spread-out (large) attack surface are the two traps of the old-school perimeter model.
