简述Ethernet Channel Technology 与PAgP （Port Aggregation Protocol ） 的区别

第1题：

第2题：

Which statement is true regarding the Port Aggregation Protocol？ （）

• A、Configuration changes made on the port-channel interface apply to all physical ports assigned to the portchannel interface.
• B、Configuration changes made on a physical port that is a member of a port-channel interface apply to the port-channel interface.
• C、Configuration changes are not permitted with Port Aggregation Protocol； instead， the standardized Link Aggregation Control Protocol should be used if configuration changes are required.
• D、The physical port must first be disassociated from the port-channel interface before any configuration changes can be made.

第4题：

Which two statements about SAN port channels configured on Cisco Nexus 5000 Series switches are true？ （）  

• A、 The bring up protocol automatically detects and overrides any misconfiguration.
• B、 You can manually configure channel groups， or they can be automatically created.
• C、 Changes in configuration to the SAN port channel interface must also be made to all members of the channel group.
• D、 The port channel protocol uses the exchange fabric parameters command to communicate across peer ports in an ISL.
• E、 The port channel protocol ensures that a set of ports is eligible to be part of the same SAN port channel.

第10题：

Which of the following describes the advantage of using Fibre Channel over Ethernet （FCoE） in POWER6 and POWER7 Blades？（）

• A、The FCoE card provides both LAN and fibre channel function from a single card on the blade. 
• B、The FCoE advanced technology removes the need for any BladeCenter switching to support this function.
• C、Component reliability on the fibre channel over Ethernet is higher than on regular Ethernet and fibre channel adapters.
• D、The AIX device driver for FCoE has been completely rewritten for the current adapter， eliminating errors and performance issues.
