1.What is the core reason why video conferencing supports public and private network traversal? A. There is a firewall or NAT, so public and private network traversal must be supported. B. Signaling and media transmission channels are not unified C. There is a media transmission address in the signaling, and the NAT device only performs address translation on the IP header, so public and private network traversal processing is required. D. Because the network performs address translation on IP packets Answer: C

2.In video conferencing, which anti-packet loss method will not increase network bandwidth? A. ARQ packet loss retransmission B. FEC forward error correction C. Packet loss compensation PLC D. Redundant coding Answer: C

3.Which of the following descriptions about HD terminals is correct? A. HD video terminals cannot communicate with SD video terminals B. HD video terminals must be registered to GK to communicate C. The high-definition video terminal supports remote control of the camera D. The password for the HD video terminal WEB page cannot be empty. Answer: C

4.Which statement is correct about Huawei's video network recording and broadcasting solution? A. Only the SMC interface and telepresence central control interface can control recording and playback. B. The terminal recording and broadcasting request will be sent to the MCU, and then the MCU will perform unified recording and broadcasting operations. C. When the meeting ends, the recording server will return the recording address to SMC, and SMC will notify the user via email to watch on-demand. D. Support point-to-point recording and local recording Answer: C

5.Which of the following is the core reason why a video conferencing system requires a public-private network traversal function? A. The IP header of the private network device needs to be address translated. B. The signaling and media transmission channels are not unified. C. There is a media transmission address in the signaling, but the NAT device only performs address translation on the IP header. D. Because the network performs address translation on IP packets. Answer: C

6.Among the following application modes, () video conferencing has the highest interactivity requirements. A. Peer-to-peer mode B. Small-capacity multi-point conference C. Large-capacity multi-point conference D. Cascading conference Answer:A
