In this process, the H.225 RAS signaling interaction between T1 and T2 must pass through the SC.

In this process, the H.225 call signaling interaction between T1 and T2 must pass through the SC.

In this process, the media stream must be directly transmitted between T1 and T2.

Endpoint control signaling involved in this process mainly includes H.225 RAS, H.225 Call Signaling, and H.245.

225 RAS messages (registration, admission, status) always traverse the SC (gatekeeper) for endpoints in the same zone.

NO.32 An AVC conference is scheduled on the CloudMCU (working in SFU mode) and VP9850 (working in IAU mode). After the conf get strmInfo 41353221 command is executed on the CloudMCU, the following information is displayed:

Which of the following is the video stream number generated after the IAU decodes and re-encodes the three video streams of Site (16), Site (17), and Site (18)?

2710124363957

2710124429801

NO.34 Which of the following statements is false about point-to-point calls?

During a point-to-point call, the Alerting signaling is used during the H.225/RAS connection.

During a point-to-point call, the called endpoint sends a call request to the GK after receiving a SETUP message.

During a point-to-point call, the GK receives two call requests.

During a point-to-point call, H.245 performs capability set matching before the logical channel is opened.

NO.35 Which of the following network elements can be utilized to centrally manage and control, remotely schedule shutdowns, and perform batch OTA upgrades for 10,000 IdeaHub ES2 Plus devices?

TRUE

FALSE

NO.37 At an SMC video conferencing system site, the customer wants to deploy a conferencing system with converged firewall ports, with a planned DMZ. The SC1 is deployed on the intranet and SC2 is deployed in the DMZ. In this case, which of the following deployment modes is the most suitable one for SC1 and SC2?

SC1 and SC2 are both registration SCs.

SC1 is the registration SC, and SC2 is the proxy SC.

SC1 is the proxy SC, and SC2 is the registration SC.

SC1 and SC2 are both proxy SCs.

NO.38 In a SIP multipoint conference, if BFCP Trans Type is set to TCP on the MCU, the BFCP communication protocol must be set to TCP on the endpoint.

TRUE

FALSE

NO.39 Which of the following statements are true about the SC cluster reconstruction deployment scenario? (Choose all that apply.)

If the number of SIP endpoints is much greater than that of H.323 endpoints, an SC cluster can be deployed for SIP and H.323 endpoint access.

If the number of SIP endpoints is much greater than that of H.323 endpoints, an SC cluster can be deployed for SIP endpoint access. The non-cluster registration SC is reserved for H.323 endpoint access.

If the number of SIP endpoints is far less than that of H.323 endpoints, you are advised not to deploy the SC cluster.

If the number of connected extranet soft clients is greater than 2000, you are advised to reconstruct a non-cluster proxy SC into a proxy SC cluster.

NO.40 SIP is an application-layer protocol independent of the transport-layer protocols. It can be carried over different transport protocols, such as UDP, TCP, TLS, and SCTP. Currently, SCTP is the most commonly used transport-layer protocol.

TRUE

FALSE

NO.41 Which of the following statements is true about image sampling?

The YUV 4:2:0 sampling mode is half the size of the YUV 4:4:4 sampling mode.

For human eyes, the Y component in YUV is the most important. Therefore, downsampling can be performed on the UV components.

RGB components have weak correlation, which is unfavorable for video image compression. Therefore, RGB is often used for image display.

The transmission rate of video data using YUV 4:2:0 is 140 Mbit/s. If the 4:2:2 mode is used, the transmission rate required by the video is 175 Mbit/s.

NO.42 Which of the following is the maximum number of cascaded conference levels supported by the SMC?

NO.43 Which of the following statements are true about the intranet-only SC cluster network? (Choose all that apply.)

The intranet registration SC cluster provides only SIP registration.

The intranet SC cluster supports two distribution modes: single-active distribution and multi-active distribution.

A standalone SC should be deployed to provide registration services specifically for H.323 endpoints.

If a large number of SIP hard endpoints or soft clients are located on the intranet, you can deploy a registration SC cluster on the intranet.

323 endpoints must register with a standalone SC when an intranet-only cluster is used.

NO.44 When the MCU has two service network ports, you can use the IP address bound to bond0 or bond1 to access the MCU web interface.

TRUE

FALSE
