Question 87

Regarding EPON, which of the following descriptions is incorrect?

A.In the upstream direction from the ONU to the OLT, each ONU uses the broadcast mode to share the upstream bandwidth.

B.The EPON standard is one of many TDM-PON standards and has the basic characteristics of a TDM-PON network: a tree topology network is composed of OLT, ONU and ODN (Optical Distribution Network).

C.In the logical topology, the EPON protocol establishes a logical link for the OLT to each ONU, and the leading byte of the Ethernet data frame carries the logical link identity, that is, LLID (Logical Link Identity).

D.The downstream data stream from the OLT to the ONU is encapsulated as an Ethernet message, and the corresponding LLID is attached and sent in the tree PON network. The optical splitter in the ODN broadcasts the data stream to each branch, and all ONUs can receive the downlink Ethernet data frame, and selectively receive their own data according to the LLID.

Question 88

Regarding OLT+MDU networking and OLT+ONT networking, what are the correct statements about multicast configuration?

A.The configuration of the two on the OLT is the same.

B.When the unicast VLAN and the multicast VLAN are different, under the OLT+MDU networking, an additional gemport-maping and service-port for the multicast VLAN on the MDU should be added on the OLT.

C.When the unicast VLAN and the multicast VLAN are different, the configuration of the two on the OLT is the same.

D.None of the above

Question 89

If you want to test the optical transmit power of the ONU, connect a common power meter to the upstream port of the ONU and select the 1310 nm wavelength to read the power value.

A.TRUE

B.FALSE

Question 90

When other SNMP parameters are configured correctly, how to configure the trap source address of the device to ensure that the network manager can receive device alarms normally?

A.The trap source address is set to the loopback address
