Switch interfaces that are configured in the on mode will exchange PAgP packets False True Question 7 of 22 8. When using LACP, what transmits outgoing frames from the MAC client to links in aggregation group? The Collector Marker Marker Response The Distributor Question 8 of 22 9. Which of the following statements are FALSE in regards to LACP Port Priority? The default port priority is 32,768 The default port priority is 65,535 The default port priority is 1 The default port priority is 0 The lower the value, the more likely that the interface will be used for LACP transmission The higher the value, the more likely that the interface will be used for LACP transmission Question 9 of 22 10. What happens if Switch Port Analyzer (SPAN) is configured for a member port in an Etherchannel? SPAN is enabled for ALL ports in the Etherchannel SPAN is automatically enabled for the logical Port-Channel interface SPAN is enabled only for that port The port will be removed from the Etherchannel group Question 10 of 22 11. Click on the Exhibit. What is TRUE in regards to this configuration? FastEthernet 0/2 and FastEthernet 0/3 will be successfully bundled The Etherchannel will not successfully form FastEthernet 0/3 will be placed into a suspended state FastEthernet 0/2 will be placed into a suspended state The switch will return an error message Question 11 of 22 12. Which of the following commands allows for the creation of the LACP administration key? Switch-1(config)#lacp admin-key 1 Switch-1(config-if)#lacp admin-key 1 Switch-1(config-if)#channel-protocol lacp admin-key 1 Switch-1(config-if)#channel-group 1 mode active Switch-1(config)#lacp administration-key 1 Question 12 of 22 13. What mode configures the port to listen passively for any received PAgP packets before creating an Etherchannel with the neighboring switch Passive Desirable On Auto Nonegotiate Question 13 of 22 14. Click on the Exhibit. What can be determined from the output in the Exhibit? The local switch is using ACTIVE mode The neighbor switch is using ACTIVE mode The neighbor switch is using PASSIVE mode The neighbor switch has an LACP System Priority of 1 The local switch has an LACP System Priority of 1 The local switch is using PASSIVE mode Question 14 of 22 15. What command can be used to view the LACP system priority? The show lacp system-priority command The show lacp sys-id command The show lacp system-pri command The show lacp system-id command The show lacp sys-pri command Question 15 of 22 16. Click on the Exhibit. What addition configuration is required to create the Layer 2 Etherchannel? Configure the Etherchannel using the interface port-channel 1 global configuration command There is no additional configuration required Configure the Etherchannel using the interface portchannel 1 global configuration command Configure the Etherchannel using the interface channel-group 1 global configuration command Question 16 of 22 17.

What happens when a link within a port channel fails? Traffic previously carried over the failed link is distributed between the remaining links within the port channel Traffic previously carried over the failed link is moved to the next available standby link within the port channel Traffic previously carried over the failed link is moved to the next available link within the port channel Traffic previously carried over the failed link is blocked until the link is restored Question 21 of 22 22.
