What are two advantages of using LACP?

It eliminates the need for the spanning tree protocol

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

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

It provides a simulates environment for testing link aggregation

What is a best practice to use before beginning an EtherChannel implementation?

Assign affected interfaces to VLAN 1

Enable each of the affected interfaces

Assign affected interfaces to an unused VLAN

Shut down each of the affected interfaces

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

Load balancing is not needed with EtherChannel

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

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

vlans & SNMP community strings should match

Only the SNMP community strings must match

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

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

Increase the speed of the ports

Create additional broadcast domains by inserting a router between the switches

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

Which Cisco command must be used on SW2 to enable an EtherChannel, if a network administrator is configuring an EtherChannel link between switches SW1 and SW2, by using the command SW1(config-if-range)# channel-group 1 mode passive?

atech_SW2(config-if-range)# channel-group 1 mode desirable

atech_SW2(config-if-range)# channel-group 1 mode auto

atech_SW2(config-if-range)# channel-group 1 mode active

Which PAgP mode combination will establish an EtherChannel?

Switch 1 set to desirable; switch 2 set to desirable
