A network technician has been tasked with designing a WLAN for a small office. One of the requirements of this design is that it is capable of supporting HD video
streaming to multiple devices. Which of the following would be the appropriate wireless technology for this design?

A.
802.11g

B.
802.11ac

C.
802.11b

D.
802.11a

Explanation:
In this question, we need a wireless network capable of supporting HD video streaming to multiple devices. We therefore need the fastest wireless network speed
available.
802.11 is a set of IEEE standards that govern wireless networking transmission methods. The 802.11 standards commonly used today to provide wireless
connectivity in home or office wireless networks are 802.11a, 802.11b, 802.11g, 802.11n and 802.11ac.
The 802.11ac standard is the fastest wireless network supporting speeds of over 3Gbps and uses the 5-GHz band.
