Answer: B

Question No: 82

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.)

  1. You must go through each collection point at a speed that isn#39;t too fast to collect too much information nor too slow which limits the amount of information collected.

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

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

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

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

Answer: A,B

Question No: 83

Refer to the exhibit. A company requires a multi-point bridge solution with Cisco 1400 series bridges. The central bridge (B1) is set to 10 dBm, the manufacturing remote bridge (B2) is set to 20 dBm, the inventory remote bridge (B3) is set to 20 dBm, and the shop remote bridge (B4) is set to 10 dBm. What is the maximum allowed power setting for all four bridges?
