  87% (13)

Explanation

Assessing the existing wired infrastructure before deploying Wi-Fi is critical for three practical reasons. PoE requirement (D): 802.3af/at/bt Power over Ethernet is the standard way to power APs; knowing whether existing switches have PoE capability - and how much budget is available - determines whether switch upgrades are needed. Port bandwidth (E): each AP can aggregate significant wireless throughput (especially with 802.11ac Wave 2 / 802.11ax), so the uplink switch port speed (100 Mbps vs. 1 Gbps vs. multigigabit) must not be a bottleneck. Cable length (F): Ethernet is limited to 100 meters for both data and PoE delivery; runs exceeding this require either a midspan injector, IDF closet, or fiber with a media converter. QoS is a policy decision, UPS is a facilities/power concern, and CAPWAP is a software/firmware concern - none require inspecting the physical wired plant.
