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

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

Create additional broadcast domains by inserting a router between the switches

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

It eliminates the need for the spanning tree protocol

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

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

Which statement is true about EtherChannel?

PAGP cannot be used in conjunction with EtherChannel

A trunk port can be part of an EtherChannel bundle

EtherChannel can support up to a maximum of ten separate links

EtherChannel operates only at Layer 2

EtherChannel relies on existing switch ports:

FALSE

TRUE

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 auto

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

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

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

Which protocol is a link aggregation protocol?

PAgP

STP

RSTP

EtherChannel

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

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

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

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

10.

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

Interface speed, duplex & vlan should match

vlans & SNMP community strings should match

Only the switch port numbers must match

Only the SNMP community strings must match
