Which two protocols are link aggregation protocols? (Choose two.)

802.3ad* & PAgP*

Which statement describes an EtherChannel implementation?

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

The trunk link between two 2960 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 EtherChannel.*

Refer to the exhibit. Which switching technology would allow each access layer switch link to be aggregated to provide more bandwidth between each Layer 2 switch and the Layer 3 switch?

EtherChannel*

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

It is Cisco proprietary.*

Which statement describes a characteristic of EtherChannel?

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

26. Which three settings must match in order for switch ports to form an EtherChannel? (Choose three.)

Non-trunk ports must belong to the same VLAN* The duplex settings of the switch ports on both sides of the physical link must match. The interfaces must be configured to the same speed.*

An EtherChannel link using LACP was formed between two switches, S1 and S2. While verifying the configuration, which mode combination could be utilized on both switches?​

S1-passive and S2-active*

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. Which command must be used on SW2 to enable this EtherChannel?

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

What is a best practice to use before beginning an EtherChannel implementation?

Shut down each of the affected interfaces.*

Refer to the exhibit. An EtherChannel was configured between switches S1 and S2, but the interfaces do not form an EtherChannel. What is the problem?

The EtherChannel was not configured with the same allowed range of VLANs on each interface.*

Refer to the exhibit. A network administrator issued the show etherchannel summary command on the switch S1. What conclusion can be drawn?

The etherchannel is not funtional.*

Refer to the exhibit. The administrator tried to create an EtherChannel between S1 and the other two switches via the commands that are shown, but was unsuccessful. What is the problem?

Traffic cannot be sent to two different switches through the same EtherChannel link.*

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

active*

What is the most cost-effective method of solving interface congestion that is caused by a high level of traffic between two switches?

aggregate ports by using EtherChannel*

What is an advantage of using LACP?

allows automatic formation of EtherChannel links*

25. What are two advantages of using LACP? (Choose two.)

allows use of multivendor devices* & allows automatic formation of EtherChannel links*

When a range of ports is being configured for EtherChannel by the use of PAgP, which mode will form the bundled channel only if the port receives PAgP packets from another device?

auto

As the network administrator you have been asked to implement EtherChannel on the corporate network. What does this configuration consist of?

grouping multiple physical ports to increase bandwidth between two switches*

Which command will initiate EtherChannel interface configuration mode?

interface port-channel interface-identifier*

Which two load balancing methods can be implemented with EtherChannel technology? (Choose two.)

source IP to destination IP* & source MAC to destination MAC*

Which three options must match in order to establish an EtherChannel between two directly connected switches? (Choose three.)

speed of the interfaces that are used for EtherChannel* VLAN memberships of the interfaces that are used for EtherChannel* duplex settings of the interfaces that are used for EtherChannel*

Which PAgP mode combination will establish an EtherChannel?

switch 1 set to desirable; switch 2 set to desirable.​*
