The Company core switches use 802.1Q trunks to connect to each other. 
How does 802.1Q  trunking keep track of multiple VLANs？ （）

Two access points running the core feature set are connected to the same switch and are 
providing guest services. if pspf is enabled.
What must be enabled on the switch to prevent clients from seeing one another’s data？（）

You have just finished aligning a cisco aironet 1400 series wireless bridge link using 
installation mode. when you set the link back to operational mode you loose association to the root bridge.
Which action will correct the problem？（）

You are troubleshooting a problem with a Cisco 7920 wireless IP phone that is causing the
phone to drop calls. The problem appears to be a roaming bandwidth issue. In order to verify what kind ofissue it is， you decide to increase the bandwidth reserved for roaming on the WLAN controller to themaximum.
What level do you set the bandwidth to？（）

Following ticket consists of a problem description and existing configuration on the device.
