B.

Some APs are connected to a PoE switch and are also receiving power from an AC outlet.

C.

The Ethernet switch uplink ports are not connected to an 802.3-2012, Clause 33-compliant core or distribution Ethernet switch.

D.

A gigabit Ethernet switch port supporting an 802.11a/g AP auto-negotiates to 100 Mbps.

Beam width

B.

Range

AP-1 is a 3x3:2 AP. STA-3 is a 3x3:3 client. What is the maximum number of spatial streams that can be used for a downlink HT-OFDM transmission from AP-1 to STA-3?

A.

One spatial stream, because the definition of the AP indicates that it is capable of only one spatial stream.

B.

Three spatial streams, because the definition of the client indicates that it is capable of only three spatial streams.

C.

Two spatial streams, because the definition of the AP indicates that it is capable of only two spatial streams.

D.

Three spatial streams, because the definition of the AP indicates that it is capable of only three spatial streams.

Users and Network support personnel at a mid-sized equipment manufacturer have been discussing the potential uses and benefits of implementing an indoor WLAN. The network administrator and network manager have requested a meeting of senior management personnel to discuss a WLAN implementation before performing a site survey or taking any implementation steps.

C.

With 802.1X/EAP security, the AP acts as the supplicant and the controller acts as the authenticator.
