Frage 7
Frage
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?
Antworten
-
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 through the same EtherChannel link.
-
Traffic cannot be sent to two different switches, but only to two different devices like an EtherChannel-enabled server and a switch.
Frage 8
Frage

Antworten
-
active
-
auto
-
desirable
-
passive
Frage 9
Frage
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?
Antworten
-
active
-
auto
-
desirable
-
passive
Frage 10
Frage
Which statement describes a characteristic of EtherChannel?
Antworten
-
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 parallel links between a switch and a router.
-
It is made by combining multiple physical links that are seen as one link between two switches.
Frage 11
Frage
What are two advantages of using LACP? (Choose two.)
Antworten
-
increases redundancy to Layer 3 devices
-
eliminates the need for the spanning-tree protocol
-
allows automatic formation of EtherChannel links
-
provides a simulated environment for testing link aggregation
-
decreases the amount of configuration that is needed on a switch for EtherChannel
-
allows use of multivendor devices
Frage 12
Frage
Which three settings must match in order for switch ports to form an EtherChannel? (Choose three.)
Antworten
-
The switch port numbers that will be combined to form the EtherChannel must match.
-
Non-trunk ports must belong to the same VLAN.
-
The SNMP community strings must be configured the same.
-
The interfaces must be configured to the same speed.
-
The duplex settings of the switch ports on both sides of the physical link must match.
-
Port security settings on the connected physical interfaces must be configured to the same violation mode.
Frage 13
Frage

Antworten
-
channel-group group-identifier
-
interface port-channel interface-identifier
-
interface interface-identifier
-
interface range interface-identifier

-
Shut down each of the affected interfaces.
-
Enable each of the affected interfaces.
-

Frage 17
Frage
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.
