CCNA2 MODULE 6

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

• AS1-on and S2-passive

• AVS1-passive and S2-active

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

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

• • PortFast mode

• • spanning-tree state

• • allowed VLANs

• • native VLAN

• • trunking mode

What are three advantagesa 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.

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.a

• • The EtherChannel stops transmitting data until it is restarted.

• aThe EtherChannel continues transmitting data with reduced bandwidth.

When EtherChannel is implemented, multiple physical interfaces are bundled into which type of logical connection?a

• • port channel

• • loopback

• aVLAN interface

• interface range

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

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 MAC to destination IP

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

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.
