EtherChannel Quiz for Cisco exams - Networkwalks Academy

A trunk link between two switches has reached its capacity. How can this be addressed in the most economical way?

Decrease the size of inter-switch collision domain by configuring additional VLANs

Create additional broadcast domains by inserting a router between the switches

Increase the speed of the ports

Combine physical ports into a high-speed logical link by configuring the EtherChannel

EtherChannel relies on existing switch ports:

TRUE

FALSE

Which Cisco command will initiate EtherChannel interface configuration mode?

#interface range interfaced-identifier

#channel-group group-identifier

#interface port-channel interface-identifier

Which statement describes a characteristic of EtherChannel?

It can combine up to a maximum of 4 physical links

It consists of multiple parallel links between a switch and a router

It can bundle mixed types of 100 Mb/s and 1 Gb/s Ethernet links

It is made by combining multiple physical links that are seen as one link between two switches

What are two advantages of using LACP?
