Huawei HCIP-Access Certified H35-211-ENU Test Dumps Updated

1. The total downlink bandwidth of the 10G EPON PONI port is the sum of the EPON downlink bandwidth and the 10GEPON downlink bandwidth.

2. What is the downlink wavelength in the 10GGPON system?

3. The maximum splitting ratio supported by 10GGPON is:

4. During the evolution of EPON to 10G EPON, WDM wavelength division modules are added at the central office to achieve a smooth transition, and ODN coexists.

5. The complete SIP message interaction process will include multiple request and response messages. A field can be used in the header field of the SIP message to describe the specific request corresponding to the current response message. This field is:

6. Under the H.248 protocol, if the signaling IP and media IP are both 10.1.1.100/8, and the voice gateway is 10.1.1.1, when configuring the voIP service, which of the following command is wrong?

7. When the invitation message sent by user A reaches user B after passing through servers C, D, and E, the server address recorded in the VIA field in the message received by user B from top to bottom is:

8. The SIP user and the server are completed the establishment, maintenance, and removal of a voice path through a series of message interactions. Therefore, each information contained in the SIP text is one-to-one, and there will be no single information values appears multiple times.

9. The Max-Forwards field can be used in the S1P message to solve the loop QUESTION NO: to avoid endless message forwarding.

10. Regarding multicast, which of the following descriptions is incorrect?

11. The correct multicast MAC address corresponding to the multicast IP address 227.120.1.32 is:

12. Under IGMP snooping, two users under the OLT order the same program, and olt sends two join messages to the multicast router.

13. Multicast technology effectively solves the problem of single-point sending and multi-point receiving, and realizes efficient point-to-multipoint data transmission in the IP network.

14. When configuring the multicast service on the MA5600T/MA5680T, the multicast vlan program adopts the static configuration method. Which of the following options must be configured, otherwise the multicast program may not be watched?

15. The range of class D multicast addresses is from 224.0.0.0 to 238.255.255.255.

16. The IGMP version on the OLT is configured as V2. What kind of processing will the OLT do after receiving the igmr v3 join message forwarded from OnT?

17. Enable IGMP-snooping on the layer 2. When the switch port receives an IGMP join message, it monitors the message and adds the corresponding port to the multicast group.

18. Which of the following options can improve the service experience of multicast users when switching channels (shorter switching time)?

19. A total of 100 multicast users on the OLT are watching 20 multicast programs. If each multicast program occupies a bandwidth of 2M, how much multicast traffic does the OLT uplink port currently have?

20. When the backbone fiber is broken or the OLT cannot detect the expected optical signal (LOS) alarm, the possible cause is: (Multiple Choice)

21. Use OTDR to locate the position of abnormal attenuation in the optical path. After the OTDR connection is to be detected the line, which of the following parameters can be set? (Multiple Choice)

22. It can be judged by the query results that (). (Multiple Choice)

23. In the FTTB/C scenario, the ONU is connected to the phone as an AG device, and no sound failure when the SIP protocol is picked up. The possible cause is:

24. When the ONT fails or the hardware is upgraded, the ONT needs to be replaced, and the ONT service needs to be removed on the OLT, and then the ONT terminal is removed, and the new ONT service is registered and configured.

25. An IPTV user reports that the TV cannot be watched. Turn on the debugging switch on the OLT side, and the debugging print information is as follows:

Huawei(config)

Can be judged by the query results:

26. A GPON Type C dual-homing protection is deployed for a power access service, and the status of the protection group and the uplink Ethernet port is set on the OLT. When the status of the Ethernet port associated with the protection group on the OLT becomes down, which of the following description is incorrect?

27. TypeB protection provides redundant protection for both the OLT PON port and the backbone fiber. When the OLT or OLT PON port or the backbone fiber fails, manually switch to the other optical fiber.

28. In order to improve link reliability, the LT device configures the Time delay protection group through two uplink ports 0/19/0 and 0/20/0. Which of the following commands is optional?

29. When deploying GP ON Type C single-homing protection, which of the following description is correct?

30. The device will periodically send and receive LMCP packets to avoid information loss. If no packets are received within () LACP packet interaction cycles, the system considers the port to be faulty.
