1. 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-passive
- S1-on and S2-active
- S1-on and S2-passive
- S1-passive and S2-active
2. When a range of ports is being configured for EtherChannel, which mode will configure PAgP so that it initiates the EtherChannel negotiation?
- active
- desirable
- passive
- auto
channel-group mode active enables LACP unconditionally, and the command channel-group mode passive enables LACP only if the port receives an LACP packet from another device. The command channel-group mode desirable enables PAgP unconditionally, and the command channel-group mode auto enables PAgP only if the port receives a PAgP packet from another device.3. Which three interface parameters must match for an EtherChannel to form? (Choose three.)
- PortFast mode
- spanning-tree state
- allowed VLANs
- native VLAN
- EtherChannel mode
- trunking mode
4. What are three advantages of using EtherChannel technology? (Choose three.)
- Configuration tasks can be done on the EtherChannel interface.
- 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.
- There is no need to upgrade links to faster connections to increase bandwidth.
- EtherChannel uses multiple logical links to provide redundancy.
- Load balancing is not needed with EtherChannel.
5. A network administrator is configuring an EtherChannel link between two physical ports on a switch. Which statement describes the result when one of the physical ports fails?
- An STP recalculation is needed.
- The EtherChannel link fails.
- The EtherChannel stops transmitting data until it is restarted.
- The EtherChannel continues transmitting data with reduced bandwidth.
6. When EtherChannel is implemented, multiple physical interfaces are bundled into which type of logical connection?
- port channel
- loopback
- VLAN interface
- interface range
7. 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?
- desirable
- active
- auto
- passive
channel-group mode active enables LACP unconditionally, and the command channel-group mode passive enables LACP only if the port receives an LACP packet from another device. The command channel-group mode desirable enables PAgP unconditionally, and the command channel-group mode auto enables PAgP only if the port receives a PAgP packet from another device.8. Which two load balancing methods can be implemented with EtherChannel technology? (Choose two.)
- source IP to destination IP
- source MAC to destination MAC
- destination IP to destination MAC
- destination MAC to source MAC
- destination IP to source IP
- destination MAC to destination IP
9. Which function is provided by EtherChannel?
- enabling traffic from multiple VLANs to travel over a single Layer 2 link
- spreading traffic across multiple physical WAN links
- dividing the bandwidth of a single link into separate time slots
- creating one logical link by using multiple physical links between two LAN switches
10. Which statement is true about EtherChannel technology?
- All configuration tasks must be done on the individual ports in the EtherChannel link.
- STP does not run on redundant EtherChannel links.
- EtherChannel uses existing switch ports.
- Links must be upgraded to support EtherChannel.
11. Which two mode combinations would result in the successful negotiation of an EtherChannel? (Choose two.)
- active; on
- passive; auto
- desirable; desirable
- desirable; active
- active; passive
- auto; auto
12. Which two protocols are link aggregation protocols? (Choose two.)
- EtherChannel
- STP
- PAgP
- 802.3ad
- RSTP
13. When a range of ports is being configured for EtherChannel, which mode will configure LACP so that it initiates the EtherChannel negotiation?
- active
- auto
- desirable
- passive
channel-group mode active enables LACP unconditionally, and the command channel-group mode passive enables LACP only if the port receives an LACP packet from another device. The command channel-group mode desirable enables PAgP unconditionally, and the command channel-group mode auto enables PAgP only if the port receives a PAgP packet from another device.14. What will happen if a network administrator puts a port that is part of an EtherChannel bundle into a different VLAN than the other ports in that bundle?
- The EtherChannel will fail.
- 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 if either PAgP or LACP is used.
- The EtherChannel bundle will stay up only if LACP is used.
- The EtherChannel bundle will stay up only if PAgP is used.
15. When a range of ports is being configured for EtherChannel, which mode will configure LACP on a port only if the port receives LACP packets from another device?
- auto
- passive
- desirable
- active
channel-group mode active enables LACP unconditionally, and the command channel-group mode passive enables LACP only if the port receives an LACP packet from another device. The command channel-group mode desirable enables PAgP unconditionally, and the command channel-group mode auto enables PAgP only if the port receives a PAgP packet from another device.
