EtherChannel Quiz for Cisco exams - Networkwalks Academy

Which one of below is an advantages of using EtherChannel technology?

EtherChannel uses multiple logical links to provide redundancy

The Spanning Tree Protocol shuts down the unused interfaces in the bundle to avoid loops

A spanning tree recalculation is not required when a single link within the channel goes down

Load balancing is not needed with EtherChannel

What are two advantages of using LACP?

It allows the use of multivendor devices & automatic formation of EtherChannel links

It provides a simulates environment for testing link aggregation

It eliminates the need for the spanning tree protocol

It decreases the amount of configuration that is needed on a switch for EtherChannel

Which PAgP mode combination will establish an EtherChannel?

Switch 1 set to desirable; switch 2 set to desirable

Switch 1 set to auto; switch 2 set to auto

Switch 1 set to on; switch 2 set to desirable

Switch 1 set to auto; switch 2 set to on

Which protocol is a link aggregation protocol?

STP

PAgP

RSTP

EtherChannel

Which statement is true regarding the use of PAgP to create EtherChannels?

It increases the number of ports that are participating spanning tree

It requires more physical links than LACP

It mandates that an even number of ports (2, 4, 6) be used for aggregation

It is Cisco Proprietary

Which settings must match on both sides of the switch ports to form an EtherChannel?

Only the switch port numbers must match

Interface speed, duplex & vlan should match

Only the SNMP community strings must match

vlans & SNMP community strings should match
