Free CWNP CWNA-106 Exam Dumps Questions & Answers

Prior to association, what parameter can 802.11 client devices measure and use to select the optimal access point for association?

• A.Proximity to potential access points
• B.Average round trip time to reach the Internet DNS server
• C.Average round trip time to reach the IP router
• D.Retry rate of probe request and responseframes
• E.Signal strength of access point beacons received

As you prepare for a site survey in a multi-floor corporate office, you have learned about several wireless devices that support connection-oriented, real-time applications. These applications are sensitive to service interruptions and require excellent signal quality, low latency, and low loss. For that reason, it is important to identify sources of RF interference as well as building characteristics that would cause RF blockage or dead spots.
What systems or environmental characteristics are most likely to cause interference or RF blockage and disrupt service for these applications? (Choose 2)

• A.Elevator shafts
• B.Narrow hallways
• C.Microwave ovens
• D.Workspace dividers
• E.RFID chokepoints

What feature(s) are most likely to be supported by 802.11 enterprise-class WLAN controllers? (Choose 4)

• A.BGP and Frame Relay
• B.IGMP snooping
• C.802.1p and DSCP QoS
• D.Captive web portals
• E.Link aggregation / port trunking

What factors will have the most significant impact on the amount of wireless bandwidth available to each station within a BSS? (Choose 2)

• A.The data rates at which nearby client stations are transmitting and receiving data
• B.The presence of co-located (10m away) access points on non-overlapping channels
• C.The layer 3 protocol used by each station to transmit data over the wireless link
• D.The power management settings in theaccess point's beacons
• E.The number of clientstations associated to the BSS

In an 802.11n 2.4 GHz BSS, what prevents each station fromusing the full network bandwidth (e.g. 130 Mbps) for user data throughput when multiple clients are actively exchanging data with the AP?

• A.APs do not have sufficient wired connection speeds to the LAN, even at 1 Gbps connections with 802.11n and earlier APs.
• B.Half of the bandwidth is allocated to uplink traffic and half to downlink traffic.
• C.WLAN devices cannot detect collisions and must receive positive frame acknowledgment.
• D.Radio receiver hardware cannot process data as quickly as it can be transmitted.
