700-765 · Question #149
Which two security risks are created by legacy approaches to networking'? (Choose two.)
The correct answer is A. slow containment C. large attack surface. Legacy networking approaches create a large attack surface due to flat, unsegmented networks and result in slow containment because they lack automated isolation and response capabilities.

Why each option
Legacy networking approaches create a large attack surface due to flat, unsegmented networks and result in slow containment because they lack automated isolation and response capabilities.
Legacy networks rely on manual processes and lack automated segmentation, meaning that once a threat is detected, security teams must respond manually, leading to slow containment and prolonged exposure windows.
User vulnerability is a general security concern related to human behavior, not a specific risk introduced by legacy network architecture.
Traditional flat network architectures do not segment users, devices, or workloads, which gives attackers broad lateral movement capability and exposes a large number of systems once a single device is compromised.
Network downtime is primarily a reliability and availability concern, not a security risk specifically created by legacy networking approaches.
Access points are physical or logical network devices and are not themselves a security risk that is uniquely created by a legacy networking approach.
