Cisco 2, Module 6

Which three interface parameters must match for an EtherChannel to form? (Choose three.)

• native VLAN

• allowed VLANs

• trunking mode

• spanning-tree state

• EtherChannel mode

What are three advantages of using EtherChannel technology? (Choose three.)

• A spanning tree recalculation is not required when a single link within the channel goes down.

• EtherChannel uses multiple logical links to provide redundancy.

• There is no need to upgrade links to faster connections to increase bandwidth.

• Configuration tasks can be done on the EtherChannel interface.

• The Spanning Tree Protocol shuts down the unused interfaces in the bundle to avoid loops.

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

• destination IP to destination MAC

• source MAC to destination MAC

• source IP to destination IP

• destination IP to source IP

• destination MAC to destination IP

Which two mode combinations would result in the successful negotiation of an EtherChannel? (Choose two.)

• active; passive

• desirable; desirable

• auto; auto

• passive; auto

• desirable; active

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

• RSTP

• EtherChannel

• PAgP

• 802.3ad

• STP

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

• passive

• desirable

• auto

• active

Which function is provided by EtherChannel?

• enabling traffic from multiple VLANs to travel over a single Layer 2 link

• creating one logical link by using multiple physical links between two LAN switches

• spreading traffic across multiple physical WAN links

• dividing the bandwidth of a single link into separate time slots

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.

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

• desirable

• passive

• active

• auto

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

• active

• passive

• desirable
