What will happen if a network administrator puts a port that is part of an EtherChannel bundle into a different VLAN than the other ports in that bundle?

• The EtherChannel will fail.
• The EtherChannel bundle will stay up if the ports were configured with no negotiation between the switches to form the EtherChannel.
• The EtherChannel bundle will stay up if either PAgP or LACP is used.
• The EtherChannel bundle will stay up only if LACP is used.
• The EtherChannel bundle will stay up only if PAgP is used.

Explanation: All ports in an EtherChannel bundle must either be trunk ports or be access ports in the same VLAN. If VLAN pruning is enabled on the trunk, the allowed VLANs must be the same on both sides of the EtherChannel.
