An administrator is troubleshooting an EtherChannel link. Which two commands will provide EtherChannel bundled link information and status of each bundled link? (Choose two.)管理員正在疑難排解 EtherChannel 連結。下列哪兩個指令可以提供 EtherChannel 綁定連結資訊及每條綁定連結的狀態？（選擇兩項。）
You have just configured two EtherChannels between two switches. Each EtherChannel contains 3 physical links. Which option describes how Layer 2 STP will react?你剛在兩台交換器之間設定了兩個 EtherChannel，每個 EtherChannel 都包含 3 條實體連結。以下哪個選項描述了第 2 層 STP 的反應？
Refer to the exhibit. Which two combinations will result in an EtherChannel being established between the two switches that are using LACP? (Choose two.)請參考展示內容。使用 LACP 時，下列哪兩種組合可以在兩台交換器之間成功建立 EtherChannel？（選擇兩項。）
Which option correctly describes the "on" mode regarding EtherChannel?以下哪個選項正確描述了 EtherChannel 的「on」模式？
For configuring EtherChannel on switch SW3, the administrator is starting the configuration by shutting down a range of interfaces, as shown below. Why is the administrator doing so? SW3(config)# interface range Ethernet0/2 - 3
SW3(config-if-range)# shutdown為了在 SW3 交換器上設定 EtherChannel，管理員先關閉一段範圍的介面，如下所示。管理員為什麼要這樣做？ SW3(config)# interface range Ethernet0/2 - 3
SW3(config-if-range)# shutdown
Which four interface characteristics must match for a link to be included into EtherChannel? (Choose four.)要將一條連結納入 EtherChannel，下列哪四項介面特性必須相符？（選擇四項。）
The administrator has configured an EtherChannel link between switches SW1 and SW2 as shown in the exhibit. However, the EtherChannel does not form. What is the likely reason for the issue? SW1(config)# interface range FastEthernet0/1 - 2
SW1(config-if-range)# channel-group 11 mode active
SW1(config-if-range)# exit
SW1(config)# interface port-channel 11
SW1(config-if)# switchport mode trunk
SW1(config-if)# switchport trunk allowed vlan 1,2,10

SW2(config)# interface range FastEthernet0/4 - 5
SW2(config-if-range)# channel-group 1 mode active
SW2(config-if-range)# exit
SW2(config)# interface port-channel 1
SW2(config-if)# switchport mode trunk
SW2(config-if)# switchport trunk allowed vlan 1,2,20管理員如展示內容所示，在 SW1 與 SW2 交換器之間設定了 EtherChannel 連結，但 EtherChannel 卻無法建立。造成此問題最可能的原因是什麼？ SW1(config)# interface range FastEthernet0/1 - 2
SW1(config-if-range)# channel-group 11 mode active
SW1(config-if-range)# exit
SW1(config)# interface port-channel 11
SW1(config-if)# switchport mode trunk
SW1(config-if)# switchport trunk allowed vlan 1,2,10

SW2(config)# interface range FastEthernet0/4 - 5
SW2(config-if-range)# channel-group 1 mode active
SW2(config-if-range)# exit
SW2(config)# interface port-channel 1
SW2(config-if)# switchport mode trunk
SW2(config-if)# switchport trunk allowed vlan 1,2,20
Which statement about the Layer 3 EtherChannel is correct?關於第 3 層 EtherChannel，下列哪項敘述正確？
