• Question 132:

  During the site survey kick-off meeting with your customer, they ask why you need to verify the existing network infrastructure. Which two reasons do you give them? (Choose two.)

  A. You need to verify the make, model, and software versions of all the equipment that will connect to the WLAN components in order to ensure compatibility.
  B. You need to verify that the equipment the WLAN components will connect to has sufficient memory capacity to support the additional WLAN connections.
  C. You need to verify that there are sufficient switch ports to support the new WLAN connections.
  D. You need to verify that the switches the WLAN components will connect to can supply 802.3af inline power, and that they have sufficient ports to support all the new WLAN devices.
  E. Depending on the type of APs that are planned for, the deployment may require different types of PoE to be supplied by the LAB switches.
  C. You need to verify that there are sufficient switch ports to support the new WLAN connections.
  D. You need to verify that the switches the WLAN components will connect to can supply 802.3af inline power, and that they have sufficient ports to support all the new WLAN devices.

• Question 133:

  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 134:

  What is the vertical height that a MAP should not exceed for proper deployment?

  A. 15 ft
  B. 30 ft
  C. 45 ft
  D. 55 ft
  B. 30 ft

• Question 135:

  A company has requested an indoor wireless survey in a multi-tenant building for 2.4GHz data and 5GHz voice services. Data clients will require three spatial streams and 4x4 MIMO technology. What is the Cisco recommended Access Point for performing this survey?

  A. 600
  B. 1600
  C. 2600
  D. 3600
  D. 3600

• Question 136:

  Refer to the exhibit.

  

  Clients in a conference room have been experiencing difficulty connecting to the Access Point on Channel 1. Which option is causing the interference?

  A. Wireless Video Camera
  B. Bluetooth Device
  C. Cordless Phone
  D. Zigbee Device
  E. Jammer
  C. Cordless Phone

• Question 137:

  What are two reasons that it is always preferable to obtain a digital copy of the "as built" drawings for a site you need to perform a WLAN site survey on? (Choose two.)

  A. A digital copy of the "as built" drawings is always more accurate than design drawings because it includes the placement of office furniture.
  B. A digital copy of the "as built" drawings includes all the changes made during construction that are not included in the design drawings.
  C. A digital copy of the "as built" drawings includes a full set of preliminary mechanical drawings so sources of interference, diffusion, and absorption can be easily identified.
  D. A digital copy of the "as built" drawings allows you to more accurately estimate physical AP placement in the customer environment.
  E. A digital copy of the "as built" drawings assists in the placement of WLAN equipment so the WLAN signal minimizes wired network delay.
  B. A digital copy of the "as built" drawings includes all the changes made during construction that are not included in the design drawings.
  D. A digital copy of the "as built" drawings allows you to more accurately estimate physical AP placement in the customer environment.
