For the interface ge-1/2/3.4, what does "ge" represent？（）

A. Gigabit Ethernet

B. SONET/SDH

C. Aggregated Ethernet

D. GRE

A.Cross-connect clock main control board

B.GE optical interface board

C.XGE optical interface board

D.FE electrical interface board

A. And its functions include ().

B.Interface rate configuratio

C.Digital diagnosis for the optical interface

D.Auto shutdown function of the optical interface laser

E.Ethernet synchronizatio

在查看具体物理NNI端口状态时（本题目以GE端口为例)，可以通过show interface gei_x/x命令查看

端口的收发包情况，同时可以通过()命令清除统计数据，以便于重新计算端口收发包的数量。

To check status of a specific physical NNI port （for example, GE port), you can execut

e command show interface gei_x/x to check packets received/transmitted on the port, and command ()to clear statistics for the convenience of recalculating packet count received/transmitted on the port.

is incorrect？ ()

A.One equipment can be configured with multiple VLANs, each with an IP address, and these IPs can locate in one network segment;

B.Qx interface of ZXCTN6263V1.0 is not available, so when the equipment acts as access NE, some port of its GE line card is used as a substitution to connect with T3 server.

C.MCC management VLAN value range should be in 3001-4093. On T3, these VLAN values are automatically shielded to prevent collison between management VLAN and service VLAN;

D.When ZXCTN6200/6300/9000 connects with an access ring in the downstream, it is recommended that the access ring form. a closed loop physically to realize MCC monitoring protection;
