Conducting Cisco Unified Wireless Site Survey V2

Question No: 101

When planning to perform a customer WLAN site survey, which three components and tasks should be considered? (Choose three.)

  1. Schedule a meeting with the customer to discuss the Statement of Work

  2. Complete the Pre-Survey Customer Questionnaire

  3. Schedule customer end user interviews

  4. Consider travel, access, and equipment requirements necessary to perform the site survey

  5. Schedule initial customer meeting and pre-survey walkthrough events

  6. Determine radio spectrum and channel allocation

  7. Determine AP and controller placement

  8. Determine customer training requirements

Answer: B,D,E

Question No: 102

When designing a WLAN, AP placement is important. How would you rank the density of APs needed to support location services versus data and voice services?

  1. Voice and data services both require a higher density of APs than location services.

  2. Data services have a lower density of APs compared to location services, but more than voice.

  3. Voice services have the highest density of APs over location and data services.

  4. Data services have the lowest density of APs compared to location services, which has the highest density.

Answer: D

Question No: 103

A customer is experiencing slower client data throughput than the data rate setting. Which two wireless characteristics are the primary contributing factors? (Choose two.)

  1. Broadcast and multicast are sent at the lowest associated data rate.

  2. 802.11 acknowledges all packets, which halves throughput on the channel.

  3. Clients that are farther from the access point connect at a slower data rate.

  4. Lower data rates decrease overall throughput.

  5. All clients on a given access point share the bandwidth of the channel.

  6. Overlapping channels cause co-channel interference.

Answer: B,E

Question No: 104

Which option allows the maximum 2.4-GHz channel usage for a survey and data deployment in the ETSI domain?

A. 1, 6, 11

B. 1, 5, 9, 13

C. 1, 6, 9, 14

D. 1, 6, 11, 14

Answer: B

Question No: 105

After you have run the VoWLAN Voice Readiness Tool in WCS 7.0, you see there are potential problem areas in your facility. Which two actions will help you troubleshoot these coverage areas? (Choose two.)

  1. Verify the green, yellow, and red regions in the RF environment only if the floor has not been calibrated.

  2. To prevent one-way audio, set the AP power levels to half the power of the client. This will ensure proper radio coverage.

  3. You need to edit the RSSI values for Cisco IP Phones so the 802.11b/g/n radios display the region map properly.

  4. Determine if the coverage area will have enough APs to support the VoWLAN client, since all APs must have a Tx power level that does not exceed that of the client.

  5. Set the AP power level to match the VoWLAN client to avoid one-way audio.

Answer: D,E

Question No: 106

An engineer installed a 1252 AP and is getting power from the switch. However, devices connected to the wireless network cannot get 802.11n data rates. What supported switchport protocol or standard could be the reason for this?

A. 802.3af B. 802.3at C. 802.1p

D. 802.11e

Answer: A

Question No: 107

Which three basic pieces of information will you need to perform a WLAN site survey? (Choose three.)

  1. How many customer user interviews will be required?

  2. Which network hardware vendor do they currently use for their infrastructure?

  3. What is the location of the facility that needs to be surveyed?

  4. What financial information will my company need to provide to the customer?

  5. How many engineers will be required to perform the work?

  6. What is the expected timeline to complete the project?

Answer: C,E,F

Question No: 108

Which two are impacts of having 802.11b clients in an 802.11g network? (Choose two.)

  1. 802.11b clients will degrade throughput of 802.11g clients

  2. 802.11b is more susceptible to multipath than 802.11g

  3. 802.11b operates over fewer channels than 802.11g

  4. 802.11b uses 20 MHz wide channels, 802.11g uses 40 MHz wide channels

  5. 802.11b is more susceptible to attenuation than 802.11g

Answer: A,B

Question No: 109
