EtherChannel Quiz for Cisco exams - Networkwalks Academy

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

It is Cisco Proprietary

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

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

Active

Passive

Auto

Desirable

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

Create additional broadcast domains by inserting a router between the switches

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

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

What are two advantages of using LACP?

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

It provides a simulates environment for testing link aggregation

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

It eliminates the need for the spanning tree protocol

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 SNMP community strings must match

Only the switch port numbers must match

Which statement is true about EtherChannel?

EtherChannel operates only at Layer 2

A trunk port can be part of an EtherChannel bundle

EtherChannel can support up to a maximum of ten separate links

PAGP cannot be used in conjunction with EtherChannel

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

Source IP to destination IP, Source MAC to destination MAC

Destination MAC to destination MAC

Destination MAC to destination IP, Destination MAC to destination MAC

Destination MAC to Destination IP

10.

Which statement describes a characteristic of EtherChannel?

It can combine up to a maximum of 4 physical links

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

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

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