問題 #35
Which of these CloudRSE user roles can release conference recordings?
Choose two
答案：C,D
解題說明：
Huawei CloudRSE implements role-based access control to separate system administration, media-content management, ordinary video access, and guest viewing.
The recording and streaming server supports four user roles: system administrator, media administrator, common user, and guest. Each role has different permissions associated with managing and accessing recorded content.
Option A is correct because the system administrator possesses administrative authority over the CloudRSE platform and can manage recorded programs, including releasing recordings.
Option C is correct because the media administrator is specifically authorized to manage recording and streaming content. Its responsibilities include editing program information, managing video metadata, releasing recorded programs, and removing published recordings.
Option B is incorrect because guests are restricted to viewing public content made available to them. They cannot perform recording-release operations.
Option D is incorrect because common users do not possess the general media-administration permissions required for releasing recorded programs through the CloudRSE management interface.
Huawei's Lab Guide explicitly identifies the system administrator and media administrator as the roles authorized to manage and release recorded programs.
The documented release procedure is performed through Programs > Release Management > Videos to Be Released, where an authorized administrator selects the appropriate recording and clicks Release.
Therefore, the correct selections are A and C.
Huawei reference: Lab Guide, Section 4.7.9, Releasing Recorded Programs, PDF pages 148-149; Training Material, PDF pages 496 and 509-511, Role- and Right-based Management and Managing Permissions.
問題 #36
After the IdeaHub is powered on for the first time, restored to factory settings, or restarted, the startup wizard screen is shown by default.
答案：B
解題說明：
Huawei IdeaHub provides a startup wizard to guide administrators through the initial configuration of a newly deployed endpoint.
The wizard is displayed when the IdeaHub is powered on for the first time or after the device has been restored to its factory settings.
During initialization, administrators configure settings such as language, region, time zone, network connectivity, administrator credentials, and other applicable system parameters.
Once the configuration process is completed, the IdeaHub retains its settings during normal operation.
A standard restart does not automatically remove these saved settings or require the initial configuration wizard to run again. The device is expected to restart using its existing configuration and return to its normal operating environment.
The statement incorrectly includes restarting as a condition that automatically displays the startup wizard.
Therefore, option B is correct.
Huawei's Training Material explicitly identifies first-time power-on and factory restoration as the two conditions under which the startup wizard appears by default. It does not include a normal restart.
This distinction is operationally important because restarting an endpoint is a routine maintenance action, whereas restoring factory settings is a configuration-reset operation that may require administrators to reconfigure the device.

問題 #37
Which of these operations can be carried out through the endpoint web interface?
Choose five
答案：A,B,C,D,E
解題說明：
Huawei video conferencing endpoints provide a web-based management interface for configuration, monitoring, media control, maintenance, and fault diagnosis.
Option A is correct because the interface displays the operational status of input and output ports. The Lab Guide demonstrates how administrators can inspect port-status indicators to determine whether connected peripherals and media interfaces are functioning.
Option B is correct because the web interface supports configuration of system parameters, network settings, endpoint services, and associated device functions.
Option C is correct because the interface provides network-related information and server-registration status, enabling administrators to verify communication with H.323 and SIP signaling infrastructure.
Option D is correct because administrators can perform audio and video operations through endpoint management controls, including camera-related adjustments and other supported media functions.
Option E is correct because the web interface provides maintenance and troubleshooting capabilities. These include diagnostic functions, operational information, and mechanisms for examining endpoint faults.
Huawei's Lab Guide introduces the endpoint web interface as an essential operational tool in Experiment 1, while the Training Material describes the diagnostic and maintenance capabilities.
All five options represent supported functions. Consequently, there is no incorrect alternative in this question.

問題 #38
If a point-to-point call cannot be established between two video-conferencing endpoints, which of the following methods can be used to identify the fault?
Choose four
答案：A,B,C,D
解題說明：
Huawei's endpoint troubleshooting methodology requires engineers to examine network connectivity, registration status, signaling behavior, and endpoint call-handling configuration when a point-to-point conference cannot be established.
Option A is correct because IP connectivity is fundamental to successful communication. Engineers should verify network reachability and determine whether intervening firewalls are blocking the required signaling or media traffic.
Option B is correct because the dialing method must match the endpoint's registration state. Huawei's Lab Guide explains that unregistered endpoints can initiate calls using the destination IP address, while registered endpoints can use assigned endpoint numbers when the call route is reachable.
Option C is correct because signaling diagnostics provide information about call-establishment exchanges and failures. These diagnostics can help isolate problems involving registration, routing, signaling messages, or incompatible configurations.
Option D is correct because the endpoint's answer mode influences how incoming calls are handled. An endpoint configured for manual answering requires user intervention, whereas automatic answering permits calls to be accepted without manual confirmation.
All four checks address different components of call establishment. Using them together provides a structured diagnostic process and helps distinguish transport failures from signaling or endpoint-configuration problems.

問題 #39
A company has deployed three MCUs within the same service area. When starting a conference, it needs to preferentially choose the MCU that has the greatest number of available ports for the conference connection.
Which feature is required to accomplish this?
答案：A
解題說明：
Load balancing is the MCU resource-management mechanism that preferentially allocates conference connections to the MCU with the greatest available resource capacity within an MCU resource pool.
In the described deployment, three MCUs belong to the same service area. When participants initiate a conference, the SMC evaluates available MCU resources and directs connections to the most suitable device.
Huawei's resource-pool scheduling mechanism preferentially selects the MCU with the most abundant available resources.
Option A is therefore correct.
Option B, intra-pool backup, provides recovery within the same MCU resource pool. If an MCU fails, conference services can be transferred to another available MCU in that service area.
Option C, inter-pool backup, provides recovery across service areas. It is used when the original service area cannot provide the required resources or experiences an applicable failure condition.
Option D, automatic cascading, combines resources from multiple MCUs when a single MCU cannot independently accommodate the required conference capacity.
The critical requirement in the scenario is preferential resource selection during conference establishment, not fault recovery or combining multiple MCUs.
Huawei's Training Material explicitly identifies load balancing as the mechanism that gives preference to the MCU with the greatest available resources. This directly supports option A.
