What destination addresses are PAgP and LACP packets/frames sent? LACP packets are sent to the destination Multicast MAC address 01-80-C2-00-00-02 LACP packets are sent to the destination Multicast MAC address 01-00-0C-CC-CC-CC LACP packets are sent to the destination Multicast MAC address 01-00-0C-9F-F0-CC PAgP packets are sent to the destination Multicast MAC address 01-80-C2-00-00-02 PAgP packets are sent to the destination Multicast MAC address 00-00-0C-07-AC-CC PAgP packets are sent to the destination Multicast MAC address 01-00-0C-CC-CC-CC PAgP packets are sent to the destination Multicast MAC address 01-00-0C-9F-F0-CC LACP packets are sent to the destination Multicast MAC address 00-00-0C-07-AC-CC Question 12 of 22 13. Click on the Exhibit. Which command produced the output illustrated in the exhibit? The show pagp 1 internal command The show pagp 1 neighbor command The show etherchannel 1 summary command The show etherchannel 1 brief command Question 13 of 22 14. What happens if Switch Port Analyzer (SPAN) is configured for a member port in an Etherchannel? SPAN is automatically enabled for the logical Port-Channel interface SPAN is enabled for ALL ports in the Etherchannel The port will be removed from the Etherchannel group SPAN is enabled only for that port Question 14 of 22 15. When using LACP, what transmits outgoing frames from the MAC client to links in aggregation group? Marker Response Marker The Collector The Distributor Question 15 of 22 16. Which of the following statements is TRUE in regards to LACP? By default, all inbound Broadcast and Multicast packets on one link in a port channel can return on any other link of the port channel No more than eight links can be assigned to an Etherchannel bundle running LACP LACP mandates that ports only be half-duplex as full-duplex is not supported LACP supports both half-duple and full-duplex ports More than eight links can be assigned to an Etherchannel bundle running LACP LACP mandates that ports only be full-duplex as half-duplex is not supported By default, all inbound Broadcast and Multicast packets on one link in a port channel are blocked from returning on any other link of the port channel Question 16 of 22 17. What mode configures the port to listen passively for any received PAgP packets before creating an Etherchannel with the neighboring switch Auto Desirable On Nonegotiate Passive Question 17 of 22 18. Which of the following commands allows for the creation of the LACP administration key? Switch-1(config-if)#channel-protocol lacp admin-key 1 Switch-1(config-if)#lacp admin-key 1 Switch-1(config)#lacp admin-key 1 Switch-1(config-if)#channel-group 1 mode active Switch-1(config)#lacp administration-key 1 Question 18 of 22 19. Which of the following statements are FALSE in regards to LACP Port Priority? The default port priority is 65,535 The default port priority is 32,768 The default port priority is 0 The higher the value, the more likely that the interface will be used for LACP transmission The default port priority is 1 The lower the value, the more likely that the interface will be used for LACP transmission Question 19 of 22 20.
