During a validation site survey, you realize that the installers mounted some of the APs above the ceiling.
They said that this was a request from the building architect due to aesthetics constraints.
During the requirements gathering, you weren't advised about any aesthetics constraints from the main stakeholder of the project. What should you do in this case?

You are conducting a physical site survey where heavy machinery is repaired. What is a common item required specifically for this type of survey?

You are validating association capabilities from clients to an 802.1X/EAP secure SSID. The RADIUS server's IP address is 10.100.50.25 and the default RADIUS authentication port is used. When testing them, none of the clients are able to associate to the SSID. Troubleshooting the WLAN infrastructure, you found out that the server is up and the RADIUS service is up as well, but the authenticator is not able to communicate properly with the server. What's your next troubleshooting step?

When performing a frame capture over the air during a voice call, you notice that frames in the downlink direction (from the AP to the client) are not being transmitted with the correct UP (User Priority) value for voice frames, but in the uplink direction (from the client to the AP), they are transmitted correctly. What is the likely cause of this issue?
