Broadcasts
WINS
DNS
NTP

In a cloud-based model, what happens when the cloud is unavailable?
The APs cease to function, and the WLAN is inoperable
The APs function based on the last received configuration
The APs switch to autonomous mode and must be manually configured
The APs switch to controller-based mode with the onside backup controller
The APs function based on the last received configuration
What is determined by the RS/CTS threshold?
The frame size at which RTS/CTS must be used
The signal strength at which RTS/CTS must be used
The number of associated clients at which RTS/CTS must be used
None of these
The frame size at which RTS/CTS must be used
While no WLAN design is easy, why is MCA RF planning simpler in 5 GHz bands?
Automatic channel planning actually works there
Signals do not propagate as far
More channels are available
We know more about the 6=5 GHz band
More channels are available
