The SMC (Service Management Center) is the central management platform for Huawei's videoconferencing solution. Its primary responsibilities include:
* Resource Management: Managing MCUs, SCs, and endpoints.
* Conference Scheduling: Providing a portal for users to book and manage meetings.
* User Management: Handling account permissions and organizational structures.
* O & M: Providing a visualized dashboard for system health and meeting quality.
Note: MCU is for media processing, and CloudRSE is for recording/streaming.

In the Huawei CloudVC 21.0 back-to-back (B2B) networking solution, firewall traversal is achieved using two SwitchCenters (SC) . To ensure security, the connection must be initiated from the more secure zone to the less secure zone.
* Intranet SC: Acts as the Traversal Client (TC) . It resides in the internal network and initiates the connection to the SC in the DMZ.
* DMZ SC: Acts as the Traversal Server (TS) . It resides in the DMZ and waits for the connection request from the intranet SC.
Statement A is incorrect because it claims the DMZ SC is the client and the intranet SC is the server, which is the reverse of the actual technical configuration. The other statements are correct: the SMC can manage extranet endpoints via the traversal link (B), extranet endpoints use the DMZ SC as their entry point (C), and CloudRSE deployment is flexible based on where the VOD/Live services are consumed (D).

Huawei provides an Open SDK for the IdeaHub to allow third-party developers to integrate their own office or industry-specific applications. For "lightweight integration," the SDK allows these apps to invoke the IdeaHub's professional-grade camera and microphone hardware. The standard performance target for these third-party integrations is 1080p HD video , providing a professional conferencing experience even when using non-native apps. While deep hardware optimization (as seen with Huawei's own WeLink or Cloud Meeting) can push certain capabilities higher, 1080p is the verified standard for lightweight integrated remote meetings.

Student eye health is a primary focus for Huawei's education products. The IdeaHub Board 2 features a specialized 4K soft-light screen that utilizes Hardware-level Optical Anti-Blue Light technology. This technology shifts the peak of harmful blue light without causing the yellow color cast associated with software filters. This feature has been rigorously tested and officially certified by TUV Rheinland (Low Blue Light Hardware Solution Certification and Eye Comfort Certification), ensuring it meets global standards for long-term viewing safety in classrooms.

The MCU (Multipoint Control Unit) web portal is a software management interface accessible via a browser once the device is already running.
* One-click information collection (A): This is a standard O & M feature used to gather system data for troubleshooting.
* Hardware status (B): The portal displays real-time data such as CPU usage, memory, and temperature.
* Logs collection (C): Administrators can download operation and system logs directly from the web UI.
* Power on (D): This is not supported because the web portal is a service provided by the MCU's operating system. If the device is powered off, the web service is not running and cannot be accessed.
To power on the device remotely, an out-of-band management tool like the Huawei iBMC (Intelligent Baseboard Management Controller) must be used.
