Which Statement Is True Regarding Modern Switching Requirements

Which statement is true regarding modern switching requirements?

A) Most older legacy switches had high port bandwidth utilization and were future proof designed to meet today's power-over-Ethernet needs.
B) Requirements for PoE are normally addressed using AC to DC power adapters. Concerns for port security for IoT devices are usually addressed using default wired encryption that all 802.3 Ethernet switches provide.
C) While APs are common, most clients are still docked and only require traditional wired connections with only the occasional dedicated PoE switch to provide power for the low number of devices needed.
D) Clients tend to prefer wireless connections, raising the need for PoE port access. There is also a growing amount of IoT devices that require security and port authentication options.
