Module 6

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

1.) A spanning tree recalculation is not required when a single link within the channel goes down. 2.) Configuration tasks can be done on the EtherChannel interface The Spanning Tree Protocol shuts down the unused interfaces in the bundle to avoid loops. 3.) There is no need to upgrade links to faster connections to increase bandwidth

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

1.) desirable, desirable 2.) active; passive

Which three are PAGP interface modes? (Choose three.)

1.) on 2.) auto 3.) desirable

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-active

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?

The EtherChannel continues transmitting data with reduced bandwidth.

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.

When a range of ports is being configured for EtherChannel, which mode will LACP on a port only if the port receives LACP packets from another device?

passive

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

port channel

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

1.) PAgP 2.) 802.3ad

Which function is provided by EtherChannel?

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

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

desirable

Which combinations of PAGP modes will form an EtherChannel? (Choose all that apply.)

1.) auto > desirable 2.) on > on

Which are benefits of EtherChannel technology? (Choose that apply.)

1.) fault-tolerance 2.) load sharing 3.) increased bandwidth 4.) link redundancy

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

1.) source IP to destination IP 2.) source MAC to destination MAC

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

1.) trunking mode 2.) allowed VLANS 3.) native VLAN

Which statement is true about EtherChannel technology?

EtherChannel uses existing switch ports.

True or False? FastEthernet and GigabitEthernet links can be combined into a single EtherChannel.

False

True or False? PAGP and LACP are both Cisco-proprietary link aggregation protocols.

False

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

active

Which PAGP interface mode will initiate negotiation with other interfaces?

desirable
