EtherChannel Quiz for Cisco exams - Networkwalks Academy

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

It is Cisco Proprietary

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

It increases the number of ports that are participating spanning tree

It requires more physical links than LACP

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 active

atech_SW2(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

Which PAgP mode combination will establish an EtherChannel?

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

Switch 1 set to desirable; switch 2 set to desirable

Which statement is true about EtherChannel?

PAGP cannot be used in conjunction with EtherChannel

EtherChannel can support up to a maximum of ten separate links

EtherChannel operates only at Layer 2

A trunk port can be part of an EtherChannel bundle

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

Active

Desirable

Passive

Auto

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

Auto

Desirable

Active

Passive

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 IP

Destination MAC to destination IP, Destination MAC to destination MAC

Destination MAC to destination MAC

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

EtherChannel uses multiple logical links to provide redundancy

Load balancing is not needed with EtherChannel

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

The Spanning Tree Protocol shuts down the unused interfaces in the bundle to avoid loops

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 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

The EtherChannel bundle will stay up only if LACP is used

The EtherChannel bundle will stay up only if PAgP is used

10.
