질문 # 47
Which of the following statements describes Huawei Video Motion Enhancement (VME) technology?
정답：B
설명：
Huawei Video Motion Enhancement (VME) is a proprietary video-processing technology designed to improve perceived image quality and produce clearer, more visually appealing conference video.
The technology combines several image-enhancement operations, including noise reduction, edge enhancement, blocking artifact removal, definition processing, and image-mode adjustment. These operations improve the appearance of compressed video and help preserve visual clarity under bandwidth-constrained conditions.
Option B is correct because it accurately identifies the image-processing functions associated with VME in Huawei's Training Material.
Option A describes an intelligent participant-identification function involving face detection and name tags.
This is not the fundamental purpose of VME.
Option C describes camera image-processing capabilities associated with low-light performance and digital wide dynamic range. Although noise reduction overlaps with VME functionality, the complete description concerns camera imaging technology rather than the specifically defined VME algorithm.
Option D describes automatic exposure, automatic white balance, and camera image-mode configuration.
These are camera adaptation functions.
Huawei combines VME with H.265 video encoding to improve overall visual performance. H.265 reduces the bandwidth required for compressed video, while VME enhances perceived image quality. This combination supports high-definition conferencing at relatively low transmission rates.

질문 # 48
Assume a user needs to add several SMC conference operator accounts.
On which of the following pages must the user perform this operation?
정답：C
설명：
The Huawei Service Management Center separates system administration from routine conference operations through distinct web portals.
The SMC sys-portal is the system management interface. It provides centralized administrative capabilities, including user provisioning, organization management, conference-room provisioning, device administration, and system configuration.
Option A is correct because creating conference operator accounts is an administrative provisioning activity.
An authorized system administrator accesses the SMC system management portal and creates the required conference users.
The Lab Guide describes this process in Experiment 3. After accessing the system management interface, the administrator navigates to Service Provisioning > Organization & User Management > Organization & Conference User, selects the appropriate organization, and adds the required accounts.
Option B is incorrect because the MCU web interface is intended primarily for MCU-specific device configuration and maintenance.
Option C is incorrect because the endpoint Touch interface provides local endpoint configuration and conference operations, not centralized SMC account provisioning.
Option D identifies the SMC conference management portal. Conference administrators and common users use this interface for their authorized conference activities, but account creation is performed through the system management portal.
The fundamental distinction is between provisioning conference-management identities and performing conference-management operations using those identities.

질문 # 49
Which of the following devices support the on-premises conference function by default?
Choose two
정답：A,D
설명：
Huawei IdeaHub models differ in their default conferencing capabilities and licensing requirements. Some models support on-premises video conferencing immediately, while others require additional licensing to activate the function.
Option A is correct because the IdeaHub ES2 Plus supports on-premises conferencing. Huawei positions this model for premium enterprise meeting scenarios requiring advanced audiovisual capabilities and integrated conferencing functions.
Option D is also correct. The Huawei Training Material explicitly states that the IdeaHub S2 Pro supports on- premises meeting scenarios by default.
Option B is incorrect because the IdeaHub ES2 requires an on-premises meeting license before the corresponding functionality can be used. Huawei distinguishes the standard ES2 from the ES2 Pro and ES2 Plus in this respect.
Option C is incorrect. The IdeaHub Board 3 is not identified in the supplied V4.0 Training Material as one of the models providing the specified on-premises conference functionality by default. The course material describes the Board series primarily in the context of interactive display, education, and collaborative office applications.
The examination requires candidates to distinguish built-in conferencing capabilities from functions that depend on additional licenses.
Accordingly, the correct selections are A and D.

질문 # 50
Which of the following are the primary purposes of a remote video loopback test?
Choose two
정답：B,C
설명：
A remote video loopback test examines the video-processing and network-transmission path between two conferencing endpoints.
Huawei's Training Material explains that, during a remote loopback test, media data is transmitted from the local endpoint to the remote endpoint and subsequently returned to the local endpoint for examination.
Option B is correct because the test evaluates the transmission path between the endpoints. Network-related problems, including packet loss, excessive jitter, and connectivity faults, may affect the quality of the returned video.
Option C is correct because the loopback path includes the remote video-processing module. A failure within this module can influence the video returned to the originating endpoint.
Option A is not the primary purpose of remote loopback testing. Local video input should first be checked using local video diagnostics or a local loopback test.
Option D is also not a primary remote-loopback objective. Local display problems can be investigated through local display diagnostics and video-output checks.
Huawei explicitly identifies remote video module and network transmission as the diagnostic targets associated with remote video loopback testing.
The practical value of this test is its ability to extend fault isolation beyond the local endpoint and examine the end-to-end media path involving the remote device.
Huawei reference: Training Material, PDF page 394, Loopback Test, including the diagnostic-method and signal-flow table.
질문 # 51
Which of these user roles is permitted to manage bulletin boards?
정답：B
설명：
Huawei's Service Management Center implements role-based authorization to separate collaboration management functions among different administrator categories.
The Program administrator is the role specifically authorized to manage bulletin-board materials, programs, and associated release tasks.
Option D is correct.
Huawei's bulletin-board functionality allows authorized personnel to prepare and publish informational content for supported collaboration environments. The program administrator manages the relevant materials and release activities without receiving unrestricted system-management permissions.
Option A is incorrect because conference administrators are responsible for conference scheduling, conference monitoring, and participant-control operations within their authorized organizational scope.
Option B is not the designated bulletin-board management role. System administrators primarily manage devices, system configuration, organizational structures, user accounts, and platform maintenance. Huawei deliberately separates these responsibilities from program administration.
Option C is incorrect because security auditors are responsible for auditing system logs and identifying unauthorized operations. Their permissions do not include bulletin-board content administration.
Huawei's Training Material identifies six SMC user roles and specifically assigns bulletin-board program management to the program administrator.
This separation supports controlled publication workflows and prevents conference or infrastructure administrators from automatically gaining unrelated content-management privileges.
Huawei reference: Training Material, PDF page 60, Rights-based Administrator Permissions; pages 702-
703, User Management (1) and User Management (2).
