Q1. Which two statements about deploying a mesh network by MAPs and RAPs are true on AireOS 8.0?(choose two) A. The three main types of mesh type under the neighbor information are neighbored, parent and child. For types default neighbor and default child default is used when the neighbor BGN is not known of different from the current AP BGNif the strict matching BGN features is disabled. 

B. The backhaul client access feature cannot be enabled on a RAP that is RAP does not allow clients on its 802.11a radio 

C. To allow relaying traffic to and from the Ethernet port of a MAP,the Ethernet bridging feature must be enabled on the map 

D. A map of rap must be authorized by either PSK or EAP before joining a controller in bridge mode. 

Answer: A, C 

Q2. Which three statements about 802.11ac are true? (choose three) 

A. MU-MIMO is supported in wave 1 

B. MU-MIMO allows one AP to transmit unique data to multiple stations simultaneously 

C. when using MU-MIMI up to 8 devices can transmit data at the same time 

D. 802.11 a/b/g/n device are able to connect to 802.11ac radios 

E. it IS possible to reach 160 MHz by combining two discontinuous 80 MHz channel block 

F. 802.11 ac is supported in the 2.4- and 5-Ghz radio band 

Answer: B, D, E 

Q3. Which two statements are true based upon the output in the exhibit? (Choose two.)

B. In addition to extending battery life, U-APSD increases the latency of the traffic flow delivered over the wireless media 

C. U-APSD is configured on the access point switch port and supports the Power over Ethernet feature D. (Unscheduled automatic power save delivery) U-APSD is a Qos facility defined in IEEE 802.11e that extends the battery life of mobile clients
