A network administrator is setting up the wireless network in a small office. The administrator wants to choose a wireless protocol standard that takes advantage of 5 GHz throughput but is also compatible with a few existing devices that operate at 2.4 GHz. Which wireless standard should the administrator deploy?

  • 802.11a
  • 802.11b
  • 802.11g
  • 802.11n
  • 802.11ac
Answers Explanation & Hints:

802.11n operates at both 2.4 GHz and 5 GHz and is backward compatible with 802.11b and 802.11g. 802.11b and 802.11g operate at 2.4 GHz only. 802.11a and 802.11ac operate at 5 GHz only.
