EtherChannel Quiz for Cisco exams - Networkwalks Academy

Which protocol is a link aggregation protocol?

STP

PAgP

RSTP

EtherChannel

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

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

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

EtherChannel relies on existing switch ports:

TRUE

FALSE

Which statement is true about EtherChannel?

EtherChannel can support up to a maximum of ten separate links

A trunk port can be part of an EtherChannel bundle

PAGP cannot be used in conjunction with EtherChannel

EtherChannel operates only at Layer 2

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

Destination MAC to destination MAC

Destination MAC to destination IP, Destination MAC to destination MAC

Source IP to destination IP, Source MAC to destination MAC

Destination MAC to Destination IP

Which statement describes a characteristic of EtherChannel?

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 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

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

Shut down each of the affected interfaces

Enable each of the affected interfaces

Assign affected interfaces to an unused VLAN

Assign affected interfaces to VLAN 1

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 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

10.

What will happen if one port in an EtherChannel is configured in VLAN22 & all other ports are configured in VLAN11?

The EtherChannel bundle will stay up only if PAgP is used

The EtherChannel bundle will stay up only if LACP is used

The EtherChannel bundle will stay up if either PAgP or LACP is used

The EtherChannel bundle will stay up if the ports were configured with no negotiation between the switches to form the EtherChannel
