Q28. When using WCS 7.0 to calibrate a floor in a facility, which two factors are common to the point and linear calibration methods? (Choose two.) 

A. You must go through each collection point at a speed that isn't too fast to collect too much information nor too slow which limits the amount of information collected. 

B. You must sample both the 802.11a/n and the 802.11b/g/n network separately. 

C. If one collection point in the linear or point collection method is missed, you have to start at the beginning again. 

D. Rotating the client is only required during the point collection process because the linear method is a slowly moving process. 

E. You will only need to combine the linear and point collection methods in special spaces like hallways. 

Answer: A,B 


Q29. In post-deployment testing you have identified an area where there is a substantial rate-shift issue causing problems with the existing Cisco 7921 phones. How might you resolve this issue? 

A. Increase the AP power level to maintain higher throughput further away from the AP. 

B. Increase client RSSI, SNR, and retry values to maintain connectivity to the original AP for as long as possible. 

C. Change VoWLAN to 7925 phones. 

D. Reduce the power level of the AP so that roaming occurs before the client experiences the substantial rate shift. 

Answer:


Q30. You have completed a site survey for a customer that refurbishes/remanufactures automobile engines.
