TRUE

FALSE

Q25. Generally, the bandwidth actually occupied by a video conference is greater than the conference bandwidth. What are the possible causes? (Choose all that apply.)

IP packet headers occupy some bandwidth.

Q27. 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.

Q28. Assume endpoints T1 and T2 are registered with the same SC node zone (signaling routing is enabled on the SC). After T1 calls the number of T2 using H.323, T1 communicates with T2. How many TCP connections are established in this process?

Q29. In the non-DMZ public-private network traversal scenario (small- and medium-sized network where the SMC and SC are co-deployed), you need to configure the LAN2 port of the SC as the default routing port.

TRUE

FALSE

Q30. 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?

When the MCU of the old architecture is cascaded with the MCU of the new architecture, the proxy channel consumes bandwidth and codec resources.

When MCUs of the old architecture are cascaded, the cascading channel consumes bandwidth and codec resources.

When the MCU of the old architecture is cascaded with the MCU of the new architecture, the cascading channel consumes bandwidth and codec resources.

When MCUs of the new architecture are cascaded, both the cascading channel and proxy channel consume bandwidth and codec resources.

Q31. FILL in BLANK
Assume endpoints T1 and T2 are registered with the same SC node zone (signaling routing is disabled on the SC). After T1 calls the number of T2 using H.323, T1 and T2 communicate with each other. In this process, a total of ____________ TCP connection(s) need to be established between T1 and T2. (Enter an Arabic numeral.)

Q32. 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.)
