Which three channels can be used simultaneously in a 2.4GHz WLAN environment while avoiding any co-channel interference?

You have been asked to onboard a new Aruba 6300M in a customer deployment. You are working remotely rather than on-site. You have a colleague installing the switch. The colleague has provided you with a remote console session to configure the edge switch. You have been asked to configure a link aggregation going back to the cores using interfaces 1/1/51 and 1/1/52.
The Senior Engineer of the project has asked you to configure the switch and IQ uplink with these guidelines:
1. Add VLAN 20 to the local VLAN database with name Mgmt
2. Add L3 SVl on VLAN 20 for Management using address 10 in the
10.1.1.0/24 subnet
3. Add LAG 1 using LACP mode active for the uplink
4. Use vlan 20 as the native vlan on the LAG
5. Make sure the interfaces are all ON.
Which configuration script will achieve the task?

When using an Aruba standalone AP you select "Native VLAN" for the Client VLAN Assignment.
In which subnet will the client IPs reside?

Based on the "show ip route" output on an Aruba CX 8325, what type of route is "10.20.0.0/22, vrf default via 10.1.1.1, [110/200]"?

Refer to the exhibit. In the given topology, a pair of Aruba CX 8325 switches are in a VSX stack using the active gateway. What is the nature and behavior of the Virtual IP for the VSX pair if clients are connected to the access switch using VSX as the default gateway?
