Question1: The maximum spectroscopic ratio supported by 10G GPON is (Radio) ?

Question2: (Multi-select) Network Management U2000 adds line templates to realize the mapping of user traffic flows to
GEM PORTS, including mapping modes(Radio)

Question3: (Radio) Which of the following options can improve the service experience of multicast users when switching
channels (switching time is shorter)

Question4: When the Type C dual home protection linkage uplink detection, if the OLT or OLT uplink fails, the Type C
dual home protection can be reversed to another OLT

Question5: (Radio) 10G GPON system downlink wavelength is

Question6: (Multi-select) VLAN planning principles need to be considered

Question7: In the evolution of EPON to 10 G EPON, a smooth transition is achieved at the local level by adding WDM
WDM modules, and ODNs coexist

Question8: (Single-choice) An IPTV user reflects that the TV cannot be watched, open the debug switch on the OLT side,
and the debug printing information is as follows: huawei( config).
This can be judged by the results of the query

Question9: (Single) A total of 100 multicast users on OLT are watching 20 multicast programs, assuming that each
multicast program occupies 2M bandwidth, then how much multicast traffic is currently on the OLT upstream
port

Question10: (Single choice) The following statement about ssH connection is incorrect, yes

Question11: Under the H.248 protocol, if the signaling IP and media IP are both 10. 1 1 100/8, voice gateway is 10. 1 1 1.
When configuring voIP service, the following command is incorrect

Question12: (Radio) The following is not the QOS service model, is

Question13: (Radio) To improve link reliability, the LT device passes through two upstream ports 0/19/0 and 0/20/0
Configure the Timedelay protection group, which of the following commands is optional

Question14: The (radio) prerequisites for esight to automatically discover OLT and MXU devices by IP address are not
included

Question15: OLT can support direct replication of user packet priority as the priority of forwarding packets, and also
supports direct local configuration

Question16: (Multiple choice) Which of the following measures can be adopted by GPON in terms of traffic control

Question17: When configuring IPTV services on the U2000, what templates are included in the IGMP templates?

Question18: The (radio) 10G GPON system uses XGEN frames to encapsulate data, and the PORT ID is defined in the
XGEN header as () bits.

Question19: The (radio) device periodically sends and receives LMCP packets to avoid information loss, and if packets are
not received during ( ) LACp packet interaction cycles, the system considers the port to be down

Question20: The auto-discovery methods provided by sight are by network segment mode, ARP mode and routing mode.
At the same time, you can create a network segment or IP address of a device that does not need to be
connected as an exclusion list. Automatically skips the network segment or IP address configured in the
exclusion list during self-discovery of devices.

Question21: (Multiple choice) When the OLT main control board CPU is detected to be continuously elevated, the
following possible causes are?

Question22: (Single choice) When planning qos, it is necessary to plan reasonably according to the business, and adopt the
() scheduling mode for high-priority businesses.

Question23: (Radio) A power access service deploys GPON Type C dual attribution protection, and the protection group is
fixed with the upstream Ethernet port status on the OLT, and when the Ethernet port status associated with the
protection group on the OLT becomes down, the following description is incorrect.
