Cisco 642-732 Online Questions & Answers

• Question 171:

  You have completed a WLAN site survey for a customer. Which two pieces of information will need to be included in the final customer report? (Choose two.)

  A. Client association report
  B. Client inventory
  C. Printed cable scan certification results
  D. Map location of all APs and controllers
  E. WCS device inventory report of only the AP, WLC, and location server (MSE)
  C. Printed cable scan certification results
  D. Map location of all APs and controllers

• Question 172:

  You have been contacted by a medium sized medical center to do a site survey of their existing WLAN. The current network is set up with multiple SSIDs/VLANs to separate voice and data and the networks functioning properly. The medical center would like to add Vocera voice badges to the existing VoWLAN. Which two issues need to be considered during the site survey? (Choose two.)

  A. The additional voice endpoints may increase additional load, which may increase delay in the WLAN and cause voice quality to degrade.
  B. There will not be any issues due to adding the Vocera voice badges because they are point-to-point devices and do not require the infrastructure to communicate.
  C. Verify the WLAN is multicast enabled for Vocera voice badges.
  D. To make these devices as efficient as possible, the Vocera voice badges should be placed on their own unicast SSID/VLAN.
  E. Verify the WLAN that is being used by the Vocera voice badges is configured in the WLC to use the Gold QoS value.
  A. The additional voice endpoints may increase additional load, which may increase delay in the WLAN and cause voice quality to degrade.
  C. Verify the WLAN is multicast enabled for Vocera voice badges.

• Question 173:

  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.)

  A. Verify the green, yellow, and red regions in the RF environment only if the floor has not been calibrated.
  B. To prevent one-way audio, set the AP power levels to half the power of the client. This will ensure proper radio coverage.
  C. You need to edit the RSSI values for Cisco IP Phones so the 802.11b/g/n radios display the region map properly.
  D. 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.
  E. Set the AP power level to match the VoWLAN client to avoid one-way audio.
  D. 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.
  E. Set the AP power level to match the VoWLAN client to avoid one-way audio.

• Question 174:

  When performing a site survey, what is a typical usable range for client signal strength?

  A. -70 to -90 dBm
  B. -60 to -80 dBm
  C. -45 to -65 dBm
  D. -30 to -50 dBm
  B. -60 to -80 dBm

• Question 175:

  A network engineer is conducting an active wireless survey. Which four actions must be performed to ensure a successful survey? (Choose four.)

  A. Use the same AP model for the survey that is used in production.
  B. Point the antenna of the survey laptop towards the access point.
  C. Perform the survey when site is empty.
  D. Place the survey laptop antenna on a pole while surveying.
  E. Look for potential barriers of the propagation of RF signals.
  F. Identify areas that have high user density.
  G. Use the same wireless devices that the customer will use.

  G. Use the same wireless devices that the customer will use.

• Question 176:

  What two factors could cause a post-deployment audit to show a high retransmission rate for the WLAN? (Choose two.)

  A. CRC errors
  B. Rate shifting
  C. CCX compatible clients
  D. High SNR values
  E. High RSSI values
  A. CRC errors
  B. Rate shifting

  A. blocks no more than 20 percent
  B. blocks no more than 40 percent
  C. blocks no more than 60 percent
  D. comprises a single zone to keep clear
  E. comprises multiple zones of which the first inside zone is the most important to keep clear
  F. comprises multiple zones of which the outside zone is the most important to keep clear
  B. blocks no more than 40 percent
  E. comprises multiple zones of which the first inside zone is the most important to keep clear

• Question 178:
