Question 14

Your consulting firm has recently been hired to complete a site survey for a company. Your engineers use predictive design software for the task, but the company insists on a pre-deployment site visit.
What task should be performed as part of the pre-deployment visit to prepare for a predictive design?

A. Evaluate the building materials at ABC’s facility and confirm that the floor plan documents are consistent with the actual building

B. Install at least one AP on each side of the exterior walls to test for co-channel interference through these walls

C. Test several antenna types connected to the intended Aps for use in the eventual deployment

D. Collect information about the company’s security requirements and the current configuration of their RADIUS and user database servers

Correct Answer:A

Question 15

Three access points are used within a facility. One access point is on channel 11 and the other two are on channel 1. The two access points using channel 1 are on either side of the access point using channel 11 and sufficiently apart so that they do not interfere each other when they transmit frames. Assuming no other Aps are in the vicinity, is CCI still a possibility in this network and why?

A. Yes, because the client devices connected to one of the channel 1 APs will transmit frames that reach the other channel 1 AP as well as

B. No, because the Aps are far enough apart that no CCI will occur

C. No, because CCI only occurs in the 5 GHz frequency band

D. Yes, because channel 11 loops around and causes CCI with channel 1

Correct Answer:A
