A.Compared with the shared Hub, a port of the LAN Switch can be said to be a separate collision domain.
When the D.LAN Switch receives a packet containing an unrecognized MAC address, it forwards the packet directly from the received port.

B.LAN Switch may not recognize the MAC address, but must identify the IP address.

C.LAN Switch mainly searches for the corresponding IP address based on the MAC address of the data packet to implement data packet forwarding.

A.True

B.False

A.DHCP Simulation Test

B.BTV Simulation Test

C.voice call emulation test

D.PPPOE Simulation Test

A.Each GEM Port is identified by a unique Port-ID, Port-ID range is 0 ～ 4095 and globally assigned by the OLT, and namely each ONU/ONT under OLT can't use duplicate GEM Port of Port-ID.

B.Each GPON port supports up to 32 ONU/ONT

C.GEM Port identifies the virtual channel business between OLT and ONU/ONT, namely the channel of carrying the business flow, similar to the VPI/VCI identifier in ATM virtual connection.

D.Each T-CONT is composed by one or more GEM Ports, each GEM Port carrying a business flow. A T-CONT can carry one or more types of data flow.

A.False

B.True
