About ZXCTN equipment, which of the following commands can be executed to inquire syst

A.ZXCTN6200/6300 V1.1 can realize NAT translation functio

B.Both ZXCTN9000 2.08.30 and 2.08.31 can realize this function.

C.ZXCTN6110V1.1 can realize this function.

D.None of the above

A.For ZXCTN6100 equipment of Version 1.0, monitoring IP of EMS is LOOPBACK1 of the equipment

B.For ZXCTN6100 equipment of Version 1.1, monitoring IP of EMS is LOOPBACK1 of the equipment

C.For ZXCTN6200/6300 equipment, monitoring IP of EMS is interface IP of the equipment

D.For ZXCTN6200/6300 equipment, monitoring IP of EMS is LOOPBACK IP of the equipment

A.nSignal failure switching of tunnel depends on whether port is dow

B.nSignal failure switching of tunnel depends on whether CC packets are lost

C.n1:1 switching of tunnel depends on APS protocol and is bidirectional switching

D.n1+1 switching of tunnel depends on APS protocol and is unidirectional switching

A.nA node adjacent to failure at one side sends switching request to another node adjacent to the failure at the other side through APS protocol.

B.nNode not adjacent to the failure does not switch but just works in pass through state to transparently transmit servic

C.nWhen the network failure disappears, the service returns to original path after WTR time expires.

D.nWhen the network failure disappears, the service switches back to the original path immediately

A.Each line side interface (NNI) of ZXCTN equipment should be configured with EMS VLAN, and each VLAN should be configured with proper EMS IP;

B.ZXCTN6300/6200 support L3 routing protocol (e.g. OSPF). In 10GE ring, EMS info is forwarded through L3, and two adjacent ports on one link belong to one VLAN domain and one IP network segment;

C.After ZXCTN6100 device is upgraded into agent version, it is recommended to use L3 monitoring mode.

D.EMS VLAN ID range is in 3001～4093, and these VLAN values are automatically shielded on T31 to prevent collision between EMS VLAN and encapsulation VLAN;

A.LOC alarm

B.Mismerge alarm

C.Forced switching command (FS)

D.Manual switching command (MS)

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;

A.children

B. animals

C. houses

D. equipmen
