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?

Increase the speed of the ports

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

Create additional broadcast domains by inserting a router between the switches

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

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

Shut down each of the affected interfaces

Assign affected interfaces to an unused VLAN

Enable each of the affected interfaces

Assign affected interfaces to VLAN 1

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

EtherChannel uses multiple logical links to provide redundancy

Load balancing is not needed with EtherChannel

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

When a range of ports is being configured for EtherChannel, which mode will configure LACP so that it initiates the EtherChannel negotiation?

Auto

Passive

Desirable

Active

Which Cisco command will initiate EtherChannel interface configuration mode?

#interface interface-identifier

#channel-group group-identifier

#interface range interfaced-identifier

#interface port-channel interface-identifier

What are two advantages of using LACP?

It eliminates the need for the spanning tree protocol

It provides a simulates environment for testing link aggregation

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

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

Which load balancing method/s can be implemented with EtherChannel technology?

Destination MAC to destination IP, Destination MAC to destination MAC

Destination MAC to Destination IP

Source IP to destination IP, Source MAC to destination MAC

Destination MAC to destination MAC

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 is Cisco Proprietary

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

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

vlans & SNMP community strings should match

Interface speed, duplex & vlan should match

Only the switch port numbers must match

Only the SNMP community strings must match

10.

Which PAgP mode combination will establish an EtherChannel?

Switch 1 set to on; switch 2 set to desirable

Switch 1 set to auto; switch 2 set to on

Switch 1 set to auto; switch 2 set to auto

Switch 1 set to desirable; switch 2 set to desirable
