#interface interface-identifier

Which protocol is a link aggregation protocol?

STP

EtherChannel

RSTP

PAgP

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

It requires more physical links than LACP

It is Cisco Proprietary

It increases the number of ports that are participating spanning tree

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

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 passive

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

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

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 PAgP mode combination will establish an EtherChannel?

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

Switch 1 set to on; switch 2 set to desirable

What are two advantages of using LACP?

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

It provides a simulates environment for testing link aggregation

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 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 only if PAgP is used

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

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

Desirable

Passive

Active

Auto
