When performing a post-installation audit with an auditing tool such as Ekahau, which three steps are associated with the passive portion of the audit? (Choose three.)
A. Check for co-channel interference.
B. Make sure you emulate your customer client.
C. Survey by SSID to ensure roaming is taking place.
D. Check that you have adequate signal levels as surveyed.
E. Verify that the network traffic of physical data rate and packet loss meets user requirements.
F. Verify AP announced data rate coverage.
When performing a post-installation audit with a auditing tool such as Ekahau, which two steps are associated with the active portion of the audit? (Choose two.)
A. Check that all channels are supported by the APs regardless of client capabilities.
B. Check for co-channel interference by standing near an access point on one channel and watching for other access points that are on the same channel.
C. Verify that the network traffic of physical data rate and packet loss meets user requirements.
D. Verify smooth roaming.
E. Check to see if the signal level on other access points that are heard on the same channel is at least 19 dBm weaker than the access point that you are next to.
How does WCS 7.0 calculate the map location of devices?
A. Based on combined time difference of arrival for map APs.
B. With combined RSSI from each AP of the floor.
C. With unique RF models for RF attenuation loss characteristics obtained by download from Cisco into WCS.
D. By selecting a RF model for RF attenuation loss characteristics in WCS.
If you are calibrating for 2.4 GHz and the site will not be using 802.11 and 802.11b data rates, what should be done to ensure an accurate calibration?
A. Make sure that the access points have the unused rates disabled.
B. Make sure that you are using an 802.11b client when calibrating.
C. Make certain that there are no legacy clients when performing the calibration because they will disrupt the process.
D. Make sure to use a client that supports both 802.11b/g and 802.11a.
What is the basic difference in the manner in which a client location is determined on a map when using Cisco WCS Location v7.0 versus Cisco WCS Base?
A. Cisco WCS Base uses SNR from two or more APs, and Cisco WCS Location uses the SNR from the closest AP.
B. Cisco WCS Base uses highest SNR signal from a single AP, and Cisco WCS Location uses highest SNR signal from two or more APs.
C. Cisco WCS Base uses RSSI from a single AP, and Cisco WCS Location compares the RSSI signal strength from two or more APs.
D. Cisco WCS Base uses RSSI from two or more APs, and Cisco WCS Location uses RSSI from the closest AP.
In evaluating a post-installation WLAN deployment, problems are occurring when a client roams from one AP to another. The client bounces back and forth between APs. Which three items can be checked to resolve this issue? (Choose three.)
A. When a client roams from one AP to the next, check the client RSSI and SNR levels for both APs at the roaming point.
B. Simplify 802.1X/EAP by moving from external RADIUS to local authentication.
C. Verify the authentication being used for the same test that the client would use under production.
D. Check if the roaming settings in the AP are set properly for non-CCX clients.
E. Check the RF levels of the first AP as the client moves toward the second AP.
F. Check that the client roaming parameters are set properly.
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
In performing a post-deployment audit, you are concerned by significant changes in measured RSSI and SNR values taken on a wireless client in one location. How do you explain the differences in these values?
A. The differences in the RSSI and SNR values are a result of signal diffusion in the environment.
B. The differences in the RSSI and SNR values are a result of multipath in the environment.
C. The differences in the RSSI and SNR values are a result of signal absorption in the environment.
D. The differences in the RSSI and SNR values are a result of signal diffraction in the environment.
Which tool can best provide throughput verification?
A. WLC > Monitor > Clients > LinkTest
D. Xirrus Wi-Fi Inspector
Which two types of information should be included in the installation inventory portion of the post- installation report? (Choose two.)
A. All AP, controller, and MSE administrator credentials
B. The number and type of all WLAN clients and tags
C. The names, locations, IP addresses, MAC addresses, etc. for every AP, controller, and MSE in the WLAN
D. Results of the coverage audit performed with the site survey mapping tool
