7. Question 7 · 1

   A controller is connected to a Cisco Catalyst switch. The switch port configuration looks like this: interface GigabitEthernet 1/0/10 switchport switchport trunk encapsulation dot1q switchport trunk allowed vlan 1,20,30,50 switchport trunk native vlan 20 switchport mode trunk Which controller CLI command assigns its management interface to the native VLAN interface of the Cisco Catalyst switch?

8. Question 8 · 1

   Which type of management tasks can be completed on a Cisco WLC remotely from a wireless client?

   Choose one answer.

   • All management and configuration tasks can be performed from a wireless client except for using debug commands.
   • All management and configuration tasks, except uploads from and downloads to the Cisco WLC, are permitted.
   • In the default configuration, no management or configuration is possible through the GUI on the Cisco WLS.
   • The default configuration of the Cisco WLC allows only CLI access and then only the use of show commands, so no configuration is possible.
