Which two command sequences must you configure on a switch to establish a Layer 3 EtherChannel with an open-standard protocol? (Choose two.)

The `channel-group 10 mode on` command forces the EtherChannel without using any negotiation protocol (LACP or PAgP), thus it is not an open-standard protocol.

This sequence configures a physical interface as a Layer 3 port (`no switchport`) and adds it to EtherChannel group 10 using LACP in `active` mode, which is an open-standard protocol for negotiating link aggregation.

The `channel-group 10 mode desirable` command uses PAgP, which is a Cisco proprietary protocol, not an open-standard one.

This sequence configures the logical Port-Channel interface 10 by removing its Layer 2 switching capabilities (`no switchport`) and assigning an IP address, making it a Layer 3 routable interface within the EtherChannel bundle.

Configuring the port-channel with `switchport mode trunk` makes it a Layer 2 interface, which conflicts with the requirement for a Layer 3 EtherChannel that routes traffic directly and has an IP address assigned.
