Question 1

A network engineer is designing a new wireless network. The network needs to have these characteristics:

support high client concentration

optimize client performance

avoid interference

Which approach should be taken?

Options :

A :

Deploy APs near each other for 2.4 GHz coverage, and disable the 5 GHz radios for all APs.

B : Deploy APs near each other for 5 GHz coverage, and disable the 2.4 GHz radios for some APs.

C :

Deploy APs near each other for 2.4 GHz coverage, and disable the 5 GHz radios for some APs.

D :

Deploy APs near each other for 5 GHz coverage, and enable the 2.4 GHz radios for all APs.

Answer: C

Question 2

A wireless engineer is designing a wireless network to support real time applications over wireless. Which IEEE

protocol must the engineer enable on the WLC so that the number of packets that are exchanged between an

access point and client are reduced and fast roaming occurs?

Options :

A : 802.11w

B : 802.11r

C : 802.11i

D : 802.11k

Answer: D

Question 3

An engineer is trying to configure the APs installed in a new auditorium to use 40 MHz channels with high data rates and lower TX power. The APs in the building hallway must use lower-density design settings configured for the rest of the building. Which two configurations achieve this design? (Choose two.)

Options :

A : TPC

B : DCA

C : AP group

D : RRM

E : RF profile

Answer: C,E

Question 4

A wireless engineer is performing a post verification of a wireless network. Which two metrics does the

engineer verify to ensure that the wireless network can support voice services? (Choose two.)

Options :

A :

The coverage area must have a noise floor that does not exceed −87 dBm.

B :

The client device must have at least an −67 dBm RSSI.

C : The rate of retransmitted packets must be 15 percent or below.

D :

The rate of retransmitted packets must be 20 percent or below.

E :

The client device must have at least an −65 dBm RSSI.

Answer: B,C

Question 5

A customer has a central Cisco WLC that manages APs in FlexConnect mode. The wireless infrastructure

supports multiple small branches. One branch deploys new CCX wireless phones that are authenticated by a

central Cisco ISE via PEAP/IMSCHAPv2, and traffic is switched locally. The customer must reduce the number

of full authentication requests and optimize roaming for the new phones. Which action accomplishes the

requirement?

Options :

A : Enable CCKM on the voice SSID and add APs to a FlexConnect group

B : Enable Aironet IE on the voice SSID and add APs to an AP group.

C : Enable Aironet IE on the voice SSID and add APs to a FlexConnect group.

D :

Enable CCKM on the voice SSID and add APs to an AP group.
