Question

What are two requirements to be able to configure an EtherChannel between two switches? (Choose two.)

A) The interfaces that are involved need to be contiguous on the switch.
B) All the interfaces need to work at the same speed.
C) All the interfaces need to be working in the same duplex mode.
D) All interfaces need to be assigned to different VLANs.
E) Different allowed ranges of VLANs must exist on each end.

Answer 1

To configure an EtherChannel between two switches, all interfaces must operate at the same speed and in the same duplex mode. The interfaces do not need to be contiguous or assigned to different VLANs.

Step-by-step explanation:

To configure an EtherChannel between two switches, certain requirements must be met for a proper setup. These requirements ensure that the link aggregation works correctly and efficiently. Two such requirements are:

1. All the interfaces need to work at the same speed.
2. All the interfaces need to be working in the same duplex mode.

The interfaces don't need to be contiguous on the switch, and they don't need to be assigned to different VLANs. In fact, for an EtherChannel to function correctly, it is crucial that all included interfaces are part of the same VLAN or allowed to carry the same range of VLANs if they are configured as trunk ports.
