PW0-105 Online Practice Questions and Answers

Given: Two co-located 802.11b/g/n APs can interfere with one another and cause contention and collisions, even when the two APs are operating on non-overlapping channels (e.g. 1 and 6).

What deployment flaw could cause this problem? (Choose two)

A. The access points are mounted too closely to one another.

B. Reflective objects in the area are causing significant multipath.

C. A client station is using active scanning to probe for access points on multiple channels.

D. The output power on the access points is too high.

E. A client station authenticates to both access points, but does not associate.

F. The access points are not synchronized to the same NTP server.

Given: The network administrator at XYZ Company recently attended a training class on wireless security and realized that he should update the corporate security policy to address WLAN technology. The network administrator is listing the items that should be addressed in the security policy update, and has asked for your input.

What WLAN topics should be addressed by a company security policy? (Choose 4)

A. Theft prevention and data security of WLAN infrastructure devices

B. Wireless intrusion monitoring and response procedures

C. WLAN performance analysis baseline documentation

D. Password requirements for users and infrastructure equipment

E. Training of the IT staff on WLAN operational security

F. User density planning and AP client association thresholds

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

A. Radio receiver hardware cannot process data as quickly as it can be transmitted.

B. Half of the bandwidth is allocated to uplink traffic and half to downlink traffic.

C. The DCF and EDCA coordination functions require backoff algorithms

D. WLAN devices cannot detect collisions and must receive positive frame acknowledgment.

E. WLANs rely on the CSMA/CD protocol and must wait a collision detection period after each frame is transmitted.

As XYZ Company's wireless specialist, you have been asked to troubleshoot some unexpected frame patterns in a wireless protocol capture. Your peers explain that the network's beacon frames are inconsistent. That is, the BSSID is the same for all beacons, but the source address varies between three different addresses.

What network configuration would cause this beacon frame behavior?

A. A single AP supports multiple BSSs with different SSIDs

B. A virtual cell single channel network has been implemented

C. The beacons are from an IBSS instead of a BSS

D. Three APs still share the same default configuration.

Given: You are on-site to perform a post-deployment site survey. When verifying a multiple channel VoWiFi deployment using a VoWiFi handset, which aspect is most important?

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

B. Testing a constant conversation or handset 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 orientation/polarity of all omni-directional antennas in use by the VoWiFi clients.

When performing a site survey for a Multiple Channel Architecture (MCA) system in a multi-tenant building with six floors, what aspect should you, as the site surveyor, keep in mind?

A. All doors and windows in the building should be open during the site survey to assess maximum coverage range.

B. The omni-directional antennas of the access points should be oriented parallel to the floor to maximize the coverage pattern across as many floors as possible.

C. The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors.

D. The Fresnel Zone is completely blocked between floors so each floor is considered a separate site survey.

Given: As a station moves away from the access point to which it is associated, it changes its data rate from 54 Mbps to 48 Mbps and then to 36 Mbps.

What IEEE 802.11 term is used to describe this functionality?

A. Dynamic Rate Switching

B. Multirate Control

C. Modulation and Coding Selection

D. Rate Set Selectivity

E. Adaptive Rate Management

What is a common feature of an 802.11 WLAN client utility? (Choose two)

A. Real-time retry monitor

B. AP Signal strength meter

C. Spectrum analyzer utility

D. VLAN configuration

E. Link statistics display

What type of RF transmitter is shown in both of the spectrum analysis exhibits?

A. Military radar

B. Bluetooth mouse

C. Microwave oven

D. Wireless video camera

E. WIPS sensor

Given: Network users and IT personnel at a large machinery 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 taking any site survey or implementation steps. The first order of discussion in the meeting is corporate policy concerning implementation and use of WLAN technology.

What specific topics are appropriate in this policy meeting? (Choose two)

A. Vendor hardware recommendations

B. Business justification

C. User productivity impact

D. Antenna types

E. Obtaining permits and zoning requirements
