• Question 191:

  You are designing a wireless network for a museum. One of their requirements is to track people inside the museum and push a notification into their tablet device as soon as they step in front of a painting with information about the artist and the painting. This information must be delivered in real time. You are using regular probe request-based tracking and during testing. You notice that although the tablet Is connected to the museum Wi-Fi network, the location is not updating in real time as you move. It can take almost 2 minutes for the location to be updated. Which option is the likely reason for this issue?

  A. Cisco MSE does not perform a new location calculation for certain elements if the resulting position is not at least 5 meters different than the previous location.
  B. Probe request-based tracking is bound to delay due to the broadcast type of traffic that is not acknowledged over the air and could be lost.
  C. CCXv4 S60 is disabled by default. You must enable CCXv4 S60, which is compatible with all Wi-Ficlients. This feature comes out location updates more frequently.
  D. Probe request-based tracking is device dependent. The tablet might not send a probe request if it is maintaining a good Wi-Fi signal, which can cause slower location updates.
  C. CCXv4 S60 is disabled by default. You must enable CCXv4 S60, which is compatible with all Wi-Ficlients. This feature comes out location updates more frequently.
