AVAYA CWNA-106 QUESTIONS ANSWERSQuestion No : 1

ABC Hospital is planning a Wi-Fi infrastructure upgrade wherethe 802.11b/g Aps (HR/DSSS and ERP) would be replaced with new dual-radio 802.11n/802.11ac (HT and VHT) APs. ABC wants to minimize the time and cost associated with performing a new site survey, so they will be mounting all of the new APs in the same locations and with the same cable drops as the existing APs. What is one performance drawback with this deployment method?

A. Multipath will increase, causing excessive layer-2 retransmissions. The retransmissions will cause latency for VoWiFi handsets.

B. Increased receiver sensitivity on theVHT APs will cause them to continually change channels to avoid co-channel interference.

C. If the existing UTP cabling is not Category 3 or better, the total Ethernet backhaul for each AP will be limited to 100 Mbps.

D. The existing WLAN plan, including the AP locations, may not provide the benefits seen in HT and VHT 802.11 PHY capabilities.

AVAYA CWNA-106 QUESTIONS ANSWERS

Question No : 2

As a station moves away from the access point to which it is associated, it changes its data

rate from 600 Mbps to 540 Mbps and then to 450 Mbps.

What IEEE 802.11 term or phase is used to describe this functionality?

A. Dynamic Rate Switching

B. Multirate Control

C. Modulation and Coding Selection

D. Rate Set Selectivity

Answer: A




Question No : 3

What statement accurately describes the RF cables and connectors that are used in an

802.11WLAN system?

A. 75 and 125 ohms are the typical impedances of 802.11 WLAN connectors.

B. Two RF connectors of the same type (e.g. SMA), manufactured by different companies,

may vary in specifications.

C. Some RF connectorsdo not cause insertion loss.

D. Large diameter RF cables cause greater loss than small diameter cables.

Answer: B




Question No : 4

You are selecting antennas for a WLAN operating in the 5 GHz frequency band. What

specifications should be evaluated for an antenna before it is implemented in this WLAN

system?

A. 802.11ad compatibility

B. TPC support

C. Impedance in Ohms

D. Return Loss Rating

Answer: C




Question No : 5

When a client moves to a new BSS within an ESS, whatstep is a part of the 802.11

reassociation process?

A. The client station transmits a Reassociation Request frame to its currentaccess point.

B. The current access point informs the IP gateway of the reassociation.

C. The current access point triggers theclient’s reassociation service.

D. The new access point transmits a Reassociation Response to the client station with a

status value.

Answer: D




Question No : 6

When planning an access point deployment that utilizes Power over Ethernet (PoE)

switches at the network edge, what design decision could adversely affect the operation of

802.3-2012, Clause 33 APs?

A. All ports on theEthernet switch will be supporting Class 3 PoE powered devices.

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.

Answer: A




Question No : 7

You are onsite with a client to perform a post-deployment site survey. When verifying a

multiple channel VoWiFi deployment using a VoWiFi handset, which aspect is most

important?

A. Performingprotocol analysis with a single wireless adapter that is scanning all channels in use

B. Testing a constant conversation orhandset tone while roaming from area to area, or performing an active survey

C. Configuring DSCP-to-802.11e QoS maps on the handset for each access category.

D. Verifying the VHT functionality to handle the call volume incurred by a single VoIP phone call.

Answer: B




Question No : 8

In a Wi-Fi client configuration utility, what feature is most likely to be user configurable?

A. 802.1p to WMM mappings

B. SNMPv3 Users

C. WMM-PS Dozing Interval

D. RADIUS Server IP Address

E. EAP Authentication Type

Answer: E




Question No : 9

As defined in the 802.11 specification, legacy Power Save requires an inefficient back-andforthframe exchange process. Due to this inefficiency, many WLAN device implementations use a variation of 802.11 Power Save to accomplish the same function. What non-standard power save behavior is used by most Wi-Fi devices in actual legacy Power Save implementations?

A. Client devices ignore the TIM field and automatically send PS-Poll frames after every beacon.

B. After eachbeacon, the AP attempts to empty its frame buffer by sending Wake-on-

WLAN frames to wake each dozing client.

C. The Beacon interval is changed from the default 100 time units to 10 or less time units.

D. Clients send null data frames to the AP and switch the power management bit from 1 to

0 toreceive queued data.
