HCIP-Video Conference V2.0 H11-861_V2.0-ENU Real Exam Dumps [2022] Check Free H11-861_V2.0-ENU Dumps

1. The SR message in TCP is a sending report, which describes the sending and receiving statistics of the sending gateway.

2. In multimedia services, RTP is used for real-time data message transmission, and RTCP is used to detect the service quality of RTP sessions.

3. The voice enhancement technology Jitter Buffer uses a signal wave of human intervention to eliminate the echo signal generated in the communication process, while retaining other normal voice signals to achieve the normal use of communication.

4. Voice enhancement technology, automatic noise suppression ANR can solve the problem of the overall low or high call volume in the line.

5. Image format refers to the size or resolution of the image. Commonly used image formats include SOCIF, QCIF, CIF, ACIF, 16CIF, HD and Full HD.

6. The video signal starts from the input terminal equipment, encodes and compresses it and sends it to the network, and finally displays it. It has undergone many images processing links in the middle, mainly including: IP camera, preprocessing, compression encoding, data encapsulation and transmission, decoding, Image format changes, playback.

7. Full HD image resolution is?

8. Illuminance, expressed by the luminous flux received per unit area, expressed in lux (Lux, lx).

9. The arrangement of lamps and lanterns requires direct illumination to avoid diffuse reflection.

10. The color of the desktop should be adjacent to the skin color or gray, and avoid the same color as the skin color, the reflectivity of the desktop should be higher than the skin color to highlight the skin image.

11. Loudness indicates the strength of the sound, and which can determine the loudness?

12. The basic concept of white balance technology is "regardless of any light source, white objects can be restored to white", and the color cast phenomenon that occurs when shooting under a specific light source is compensated by strengthening the corresponding complementary color.

13. The stretching mode is full-screen stretching according to the output ratio, and part of the image will be captured.

14. The design purpose of the terminal auxiliary IP is to allow users to log in the terminal to configure or debug in the local area network, which can be used for the main business.

15. Terminals with built-in mini-MCU function can hold multipoint conferences through the built-in MiniMcU, but the processing capacity will be limited.

16. The IP addresses of FE, GEO and GE1 cannot be in the same network segment, otherwise, network failure will occur. At this time, the ALM indicator on the front panel is always on.

17. MCU built-in WEB includes multi-user management, address book management, conference management and equipment management.

18. When using the MCU wall riding mode, there is no need to add other devices for traversing the public and private networks.

19. The network port of the switch connected to the MCU must be: LOOM half-duplex.

20. Network recording service During the meeting, in addition to recording the content of the meeting, you can also watch it in real time through the live client.

21. The SMC platform, as Huawei's video conferencing service management platform, manages and schedules video conferences in a unified manner, can realize all conference control operations in video conferences, and provide customers with a convenient and fast conference management experience.

22. Forward error correction (FEC), when the two parties establish a call and detect that the media stream packet loss exceeds 0.1% within 10s, the super error correction function will be enabled, and the super borrow correction function will divide a part of the call bandwidth. It is used to transmit redundant code streams that are resistant to packet loss.

23. Peer-to-peer network, diagnosis in the case of networking without public and private network traversal.

24. The Huawei NLOG software is part of the conference scheduling and management software, and is installed and used together with the SMC conference management software.

25. In H.460 networking, the RTP keep-alive code stream is?

26. Under the static NAT network, which is wrong about the signaling description of the public network terminal calling the private network terminal?

27. The basic functions of the firewall include: content filtering, user authentication, VPN, application proxy, NAT, packet filtering & state detection, IDs and alarms, logs, etc.

28. According to the H.323 protocol, the signaling required to complete the process of capability exchange is?

29. The Call-ID header field is used as a unique identifier for a series of messages. In the dialog, in all requests and responses sent by each UA, the Call-id must be the same.

30. A SIP message consists of a start-line, a header consisting of one or more fields (riold), a blank line (CRLF) that marks the end of the header, and an optional message body (message boby) composition.
