Which of the following statements is true about image sampling?

• A.RGB components have weak correlation, which is unfavorable for video image compression. Therefore, RGB is often used for image display.
• B.For human eyes, the Y component in YUV is the most important. Therefore, downsampling can be performed on the UV components.
• C.The YUV 4:2:0 sampling mode is half the size of the YUV 4:4:4 sampling mode.
• D.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.

Which of the following MCU debugging commands is used to display detailed information about a specified conference?

• A.conf get iaures [confNum]
• B.conf get csdchaninfo [confnum]
• C.conf get strmInfo [confnum]
• D.conf get [confNum]

The virtual conference ID range of the SMC video conferencing system is set to 9100000 to 9299999. Which of the following may be the ID of a new common conference (that is not bound to a VMR)? (Choose all that apply.)

• A.9688889
• B.9300001
• C.9100009
• D.9288889

The new and old MCU architectures differ in bandwidth and codec resource usage during cascading. The new architecture supports multiple working modes, such as MCU, SFU, and IAU. The old architecture does not provide different working modes of the MCU. Which of the following statements is false about MCU cascading?

• A.When MCUs of the old architecture are cascaded, the cascading channel consumes bandwidth and codec resources.
• B.When MCUs of the new architecture are cascaded, both the cascading channel and proxy channel consume bandwidth and codec resources.
• C.When the MCU of the old architecture is cascaded with the MCU of the new architecture, the proxy channel consumes bandwidth and codec resources.
• D.When the MCU of the old architecture is cascaded with the MCU of the new architecture, the cascading channel consumes bandwidth and codec resources.

Which of the following statements are true about the intranet-only SC cluster network? (Choose all that apply.)

• A.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.
• B.A standalone SC should be deployed to provide registration services specifically for H.323 endpoints.
• C.The intranet registration SC cluster provides only SIP registration.
• D.The intranet SC cluster supports two distribution modes: single-active distribution and multi-active distribution.
• E.323 endpoints must register with a standalone SC when an intranet-only cluster is used.
