In order to facilitate management and maintenance, the AP power supply method is generally preferred to select which of the following for power supply?

Question

Options

• ASeparate power adapter
• BPOE switch
• CPOE adapter
• DAC power supply

• A
  3% (1)
• B
  74% (25)
• C
  15% (5)
• D
  9% (3)

Explanation

POE switches are the preferred power supply method for APs because they deliver both power and data over a single Ethernet cable, eliminating the need for separate power outlets at each AP location while enabling centralized power management - administrators can remotely reboot individual APs simply by toggling the corresponding switch port. A separate power adapter (A) requires an AC outlet at every AP installation point and offers no remote power control, making large-scale deployments difficult to manage. A POE adapter (C) also uses Power over Ethernet but is a single-port injector, so it lacks the scalability and unified management a switch provides when supporting dozens of APs. AC power supply (D) shares the same drawbacks as a separate adapter - local outlet dependency and no remote management capability.

Memory tip: POE Switch = one cable does two jobs (power + data) for many APs at once, all controllable from one place.
