When a range of ports is being configured for EtherChannel, which mode will configure LACP so that it initiates the EtherChannel negotiation?
Place the options in the following order:
This command shows information about the status of the port involved in the Etherchannel.
� not scored -
This command shows information about the reliability of the port-channel.
This command is used to check what port channels are configured on a switch.
This command shows the list of ports involved in the port channel and the time since the ports were bundled.

What is an advantage of using LACP?
decreases the chance of a spanning-tree loop
provides a simulated environment for testing link aggregation
allows automatic formation of EtherChannel links*
decreases the amount of configuration that is needed on a switch for EtherChannel
increases redundancy to Layer 3 devices

Which command will initiate EtherChannel interface configuration mode?
interface port-channel interface-identifier*
interface interface-identifier
interface range interface-identifier
channel-group group-identifier
Launch PT  Hide and Save PT
Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.
What are two reasons why the ping messages that are issued from Laptop0 towards Laptop1 are failing? (Choose two.)
The wrong cable types are connecting the two switches.
The channel group mode is not set correctly on the switches.
The interface VLAN 1 is shut down on both switches.
The channel group should be configured as a trunk on each switch.*
The two interfaces on each of the switches belong to different VLANs.*

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*
port numbers that are used for the EtherChannel
VLAN memberships of the interfaces that are used for EtherChannel*
duplex settings of the interfaces that are used for EtherChannel*
port security settings on the interfaces that used for EtherChannel
domain names on the switches

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?

Which statement is true regarding the use of PAgP to create EtherChannels?
It requires more physical links than LACP does.
It mandates that an even number of ports (2, 4, 6, etc.) be used for aggregation.
It is Cisco proprietary.*
It increases the number of ports that are participating in spanning tree.
It requires full duplex.

Which PAgP mode combination will establish an EtherChannel?
switch 1 set to desirable; switch 2 set to desirable.?*
switch 1 set to on; switch 2 set to desirable.
switch 1 set to auto; switch 2 set to auto.?
switch 1 set to auto; switch 2 set to on.?
What is a best practice to use before beginning an EtherChannel implementation?
Shut down each of the affected interfaces.*
Assign affected interfaces to VLAN 1.
Assign affected interfaces to the management VLAN.
Enable each of the affected interfaces.
Assign affected interfaces to an unused VLAN.
Which two protocols are link aggregation protocols? (Choose two.)

Refer to the exhibit. A network administrator has decided that an EtherChannel between ports 0/1 and 0/2 on switches S1 and S2 would help performance. After making the configuration, the administrator notices no performance gain. Based on the output that is shown, what two possible assumptions could a network administrator make? (Choose two.)
The EtherChannel bundle is working.
One of the ports on S2 was not configured correctly.*
Switch S2 must be configured so that the maximum number of port channels is increased.
LACP and PAgP were both used to form the EtherChannel.
Switch S2 did not use a compatible EtherChannel mode.
The EtherChannel bundle is not working.*
Which statement describes an EtherChannel implementation?
EtherChannel can connect up to a maximum of eight separate links.
EtherChannel operates only at Layer 2.
PAgP cannot be used in conjunction with EtherChannel.
A trunked port can be part of an EtherChannel bundle.*
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?
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*
grouping two devices to share a virtual IP address
providing redundant devices to allow traffic to flow in the event of device failure
providing redundant links that dynamically block or forward traffic

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.*
Traffic can only be sent to two different switches if EtherChannel is implemented on Gigabit Ethernet interfaces.?
Traffic can only be sent to two different switches if EtherChannel is implemented on Layer 3 switches.?
Traffic cannot be sent to two different switches, but only to two different devices like an EtherChannel-enabled server and a switch.?
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-on and S2-active?
S1-passive and S2-active*
S1-passive and S2-passive?
S1-on and S2-passive
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*
insert a router between the switches
increase uplink speed
add more VLANs to reduce broadcast domains

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 interface port-channel number has to be different on each switch.
The switch ports were not configured with speed and duplex mode.
The EtherChannel was not configured with the same allowed range of VLANs on each interface.*
The switch ports have to be configured as access ports with each port having a VLAN assigned.?
Which two load balancing methods can be implemented with EtherChannel technology? (Choose two.)
destination IP to source IP
destination MAC to destination IP
source IP to destination IP*
source MAC to destination MAC*
destination IP to destination MAC
destination MAC to source MAC
