Cisco 3 - Chapter 3: Quiz
Refer to the exhibit. On the basis of the output that is shown, what can be determined about the EtherChannel bundle? *The EtherChannel bundle is down. *The EtherChannel bundle is operating at both Layer 2 and Layer *Two Gigabit Ethernet ports are used to form the EtherChannel. *A Cisco proprietary protocol was used to negotiate the EtherChannel link.
A Cisco proprietary protocol was used to negotiate the EtherChannel link
An administrator tried to implement an EtherChannel between two switches by grouping the six physical ports as shown. (both Fast ethernet and Gigabit Ethernet) However, the administrator was not successful. What is the reason for that? *An EtherChannel link can only be created between Layer 3 switches. *An EtherChannel link can only be formed by grouping interfaces of the same type. *An EtherChannel link can only be formed by grouping interfaces of the same type. *An EtherChannel link can only be implemented on Fast Ethernet interfaces
An EtherChannel link can only be formed by grouping interfaces of the same type
What are three advantages of using EtherChannel technology? (Choose three.) *EtherChannel uses multiple logical links to provide redundancy. *Configuration tasks can be done on the EtherChannel interface. *There is no need to upgrade links to faster connections to increase bandwidth. *Load balancing is not needed with EtherChannel. *The Spanning Tree Protocol shuts down the unused interfaces in the bundle to avoid loops. *A spanning tree recalculation is not required when a single link within the channel goes down.
Configuration tasks can be done on the EtherChannel interface There is no need to upgrade links to faster connections to increase bandwidth A spanning tree recalculation is not required when a single link within the channel goes down
Which two protocols are used to implement EtherChannel? (Choose two.) *Spanning Tree Protocol *Rapid Spanning Tree Protocol *Port Aggregation Protocol *Link Aggregation Control Protocol *Cisco Discovery Protocol
Port Aggregation Protocol Link Aggregation Control Protocol
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 bundle will stay up only if PAgP is used. *The EtherChannel bundle will stay up only if LACP is used. *The EtherChannel bundle will stay up if either PAgP or LACP is used. *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.
ill in the blank. Do not use abbreviations. Which command displays only one line of information per port channel?

Refer to the exhibit. An administrator wants to form an EtherChannel between the two switches by using the Port Aggregation Protocol. If switch S1 is configured to be in auto mode, which mode should be configured on S2 to form the EtherChannel? *on *auto *desirable *off
desirable
Which statement is true about EtherChannel technology? *Configuration tasks must be done on individual ports. *EtherChannel relies on existing switch ports. *Links must be upgraded to support EtherChannel. *STP does not run on EtherChannel links.
EtherChannel relies on existing switch ports
When a range of ports is being configured for EtherChannel, which mode will configure PAgP so that it initiates the EtherChannel negotiation? *active *auto *desirable *passive
desirable
Which three interface parameters must match for an EtherChannel to form? (Choose three.) *allowed VLANs *EtherChannel mode *native VLAN *PortFast mode *spanning-tree state * trunking mode
allowed VLANS native VLAN trunking mode
