Module 6-EtherChannel

Which statement describes a characteristic of EtherChannel?

• It can combine up to a maximum of 4 physical links.

• It can bundle mixed types of 100 Mb/s and 1Gb/s Ethernet links.

• It consists of multiple independent links between a switch and a router.

• It is made by combining multiple physical links that are seen as one link between two switches.

What of the following statements regarding EtherChannel is true?

• Interfaces must operate at the same speed.

• Interfaces do not have to match duplex modes.

• Interfaces must be in the same Vlan.

• Allowed Vlan ranges can be different on each end of the Etherchannel group.

Which two channel-group modes would attempt to create a LACP Etherchannel with the other side of the connection?

• S1: on, S2: on

• S1: desirable, S2: auto

• S1: active, S2: passive

• S1: active, S2: active

Which statement concerning Etherchannel implementation is correct?

• EtherChannel operates only at Layer 2.

• A trunked port can be part of an EtherChannel bundle.

• PAgP cannot be used for establishing EtherChannels

• EtherChannel can support up to a maximum of ten separate links.

Which of the following is not a valid EtherChannel load-balancing method?

• Source IP to Destination IP

• Source MAC to Destination MAC

• Source port to destination port

• Destination IP only

Which configuration setting would form an EtherChannel between switches without PAgP or LACP autonegotiation?

• SW1: passive, SW2: active

• SW1: auto, SW2: auto

• SW1: on, SW2: on

• SW1: desirable, SW2: desirable

EtherChannel has been configured between two switches with four connections. If the physical interface for one of the trunk links changes to a down state, what happens to the Etherchannel?

• The EtherChannel will transition to a down state.

• The EtherChannel will remain functional but at a lower speed.

• Spanning Tree Protocol will transition the failed physical interface into forwarding mode.

• Spanning Tree Protocol will elect a new root bridge.

The following command is issued on SW1:
SW1(config-if-range)# channel-group 1 mode auto.

Which command must be used on SW2 to create an EtherChannel?

• SW2(config-if-range)# channel-group 1 mode on

• SW2(config-if-range)# channel-group 1 mode active

• SW2(config-if-range)# channel-group 1 mode passive

• SW2(config-if-range)# channel-group 1 mode desirable
