By default, the SMC provides six user roles. Default permissions of each user role can be modified or deleted based on site requirements.

• B.FALSE

Assume endpoints T1 and T2 are registered with the same SC node zone. After T1 calls the number of T2 using H.323, T1 and T2 communicate with each other. Which of the following statements are true about the call process? (Choose all that apply.)

• A.In this process, the H.225 RAS signaling interaction between T1 and T2 must pass through the SC.
• B.225 RAS messages (registration, admission, status) always traverse the SC (gatekeeper) for endpoints in the same zone.
• C.In this process, the media stream must be directly transmitted between T1 and T2.
• D.Endpoint control signaling involved in this process mainly includes H.225 RAS, H.225 Call Signaling, and H.245.
• E.In this process, the H.225 call signaling interaction between T1 and T2 must pass through the SC.

Which of the following statements is true about image sampling?

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

Which of the following operations needs to be performed when you log in to the SC as the admin user using the CLI for the first time?

• A.Delete user configuration.
• B.Configure the SC IP address.
• C.Configure a default route for SC.
• D.Change the default password.

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