NEW QUESTION # 31
What is the highest supported video-conference resolution when an IdeaHub is used for cloud conferences?
Answer: A
Explanation:
Huawei IdeaHub supports both cloud-based video conferencing and on-premises conferencing, with available video resolutions depending on the conferencing mode and product capabilities.
For cloud conferencing, the HCIA-Collaboration V4.0 Training Material specifies support for 1080p high- definition video meetings.
Huawei IdeaHub can run mainstream cloud conferencing applications directly through its supported operating- system environment without requiring an additional Open Pluggable Specification (OPS) computer.
The Training Material identifies Huawei Cloud Meeting, Huawei WeLink, Tencent Meeting, and Lark Meetings among the supported mainstream conferencing applications. The documented cloud meeting capability provides 1080p video.
Option D is therefore correct.
Option A, 4K, represents a higher resolution supported in certain on-premises conferencing configurations and presentation-sharing scenarios. However, the course material does not identify 4K as the maximum cloud conference video resolution.
Options B and C represent lower resolutions than the documented 1080p cloud conferencing capability.
The examination distinction is between the endpoint display's native resolution, supported presentation resolution, and the resolution of the cloud conferencing video stream.
A 4K display does not automatically mean that every video conferencing application can transmit and receive
4K conference video.

NEW QUESTION # 32
Which of the following is not a fault-diagnostics method available through the IdeaHub web interface?
Answer: A
Explanation:
Huawei IdeaHub provides integrated fault-diagnostic capabilities through its web management interface.
These functions allow administrators to examine device behavior, troubleshoot audiovisual problems, and isolate hardware or network-related faults.
Option A is a supported diagnostic function. One-click diagnostics collect system information, error reports, and other diagnostic data, enabling maintenance personnel to investigate abnormalities efficiently.
Option C is also supported. Loopback testing examines audio or video signal-processing paths. Local loopback tests evaluate local processing modules, while remote loopback tests help assess remote media modules and network transmission.
Option D is supported because the color bar test provides a standardized video signal that helps engineers examine video output and display behavior. It is useful when diagnosing display-related faults or determining whether an observed image problem originates in the output path.
Option B is correct because Whiteboard test is not included among the fault-diagnostic methods available through the IdeaHub web interface.
Although IdeaHub provides interactive whiteboard functionality, this collaboration feature must not be confused with the dedicated diagnostics available through the web management interface.
Huawei's Training Material explicitly identifies one-click diagnostics, signaling diagnostics, network tests, route tests, audio tests, color bar tests, and loopback tests as supported web-interface diagnostic operations.
Huawei reference: Training Material, PDF pages 386-394, Fault Diagnostics on the Web Interface, One- Click Diagnostics, Color Bar Test, and Loopback Test.
NEW QUESTION # 33
In the video-conferencing endpoint projection scenario, when the IdeaShare client is used to project a PC screen, make sure the PC and endpoint are on the same LAN and can communicate with one another.
Answer: A
Explanation:
Huawei IdeaShare provides wireless presentation-sharing capabilities that allow users to project computer content onto compatible video conferencing endpoints without using a dedicated physical video cable.
When the IdeaShare software client is used, successful projection requires network connectivity between the computer and the target conferencing endpoint. Huawei's Lab Guide explicitly specifies that the PC and endpoint must be on the same local area network and capable of communicating with each other.
The IdeaShare client establishes a software-based projection session using the endpoint's network services.
During configuration, the user installs the IdeaShare application, launches it, enters the projection code displayed by the endpoint, and initiates screen sharing.
If the PC and endpoint cannot communicate, the projection session may fail even when the application and projection code are correct.
This requirement differs from IdeaShare Key projection, which uses a supported wireless connection mechanism and does not require the computer and endpoint to share the same LAN.
Option A is therefore correct.
For troubleshooting, administrators should verify the PC's network connection, the endpoint's IP connectivity, and the availability of the required network communication path before investigating application-specific problems.

NEW QUESTION # 34
Which of the following statements describes Huawei Video Motion Enhancement (VME) technology?
Answer: D
Explanation:
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.
Huawei reference: Training Material, PDF page 188, H.265+VME, and page 53, Super PLC and Intelligent Bandwidth Prediction.
NEW QUESTION # 35
Which of these user roles is permitted to manage bulletin boards?
Answer: C
Explanation:
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.

703, User Management (1) and User Management (2).
