EtherChannel Quiz for Cisco exams - Networkwalks Academy

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

Auto

Active

Passive

Desirable

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

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 if the ports were configured with no negotiation between the switches to form the EtherChannel

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

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 statement is true about EtherChannel?

A trunk port can be part of an EtherChannel bundle

PAGP cannot be used in conjunction with EtherChannel

EtherChannel operates only at Layer 2

EtherChannel can support up to a maximum of ten separate links

Which protocol is a link aggregation protocol?

EtherChannel

STP

RSTP

PAgP

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 will initiate EtherChannel interface configuration mode?

#interface interface-identifier

#channel-group group-identifier

#interface port-channel interface-identifier

#interface range interfaced-identifier

What are two advantages of using LACP?

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

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

10.

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 passive

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