NEW QUESTION # 23
Which of these CloudRSE user roles can release conference recordings?
Choose two
Answer: A,D
Explanation:
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.

NEW QUESTION # 24
If a video-conferencing endpoint is not registered with the server by using H.323 or SIP, endpoint A can make a point-to-point call to endpoint B by using endpoint B's IP address, provided that the two endpoints can communicate with each other.
Answer: B
Explanation:
Huawei video conferencing endpoints support point-to-point communication through direct IP-address dialing even when they are not registered with an H.323 gatekeeper or SIP registration server.
In a registered deployment, endpoints can use logical identifiers, such as H.323 numbers or SIP numbers, to establish calls. The associated signaling infrastructure resolves these identifiers and facilitates call routing.
When registration is unavailable, the endpoints can instead establish communication by directly addressing the destination endpoint's IP address.
Option A is correct because successful point-to-point communication does not inherently require registration with a central server, provided that the endpoints support compatible signaling and media capabilities and can communicate over the network.
Huawei's Lab Guide explicitly describes this procedure under Point-to-Point Call (Touch).
The administrator enters the destination endpoint's IP address in the meeting interface and initiates the call.
The endpoint then attempts to establish the connection directly.
The guide further explains that, when the connection fails, engineers should verify network reachability and the accuracy of the destination IP address.
Firewalls, routing restrictions, and incompatible endpoint configurations can still prevent communication even when the addresses are correct.
The central distinction is that server registration enables number-based calling and centralized management, whereas direct IP dialing can support point-to-point calls independently.
Huawei reference: Lab Guide, Section 1.3.1.5, Point-to-Point Call (Touch), PDF pages 25-26; Section
1.3.2.5, Point-to-Point Call (Controller).
NEW QUESTION # 25
What are the six request methods of a SIP message?
Answer: A
Explanation:
Session Initiation Protocol (SIP) is an application-layer signaling protocol used to establish, modify, and terminate multimedia communication sessions. SIP operates through request-response exchanges between User Agent Clients (UACs), User Agent Servers (UASs), and intermediary network servers.
Huawei's HCIA-Collaboration Training Material identifies six basic SIP request methods: INVITE, ACK, CANCEL, BYE, REGISTER, and OPTIONS.
INVITE initiates a multimedia session or invites a participant to join an existing session. ACK acknowledges the final response to an INVITE request. CANCEL terminates a pending request before the corresponding transaction is completed. BYE terminates an established session. REGISTER updates the user's registration or contact information with a registration server. OPTIONS queries the capabilities supported by a SIP entity.
Option B contains all six basic request methods and is therefore correct.
Options A and D incorrectly substitute MESSAGE for ACK or OPTIONS. MESSAGE is an extended SIP method used for instant-message delivery.
Option C incorrectly substitutes UPDATE for OPTIONS. UPDATE is an extended method used to modify session parameters during session establishment.
The distinction between basic and extended SIP methods is explicitly defined in Huawei's protocol curriculum and is essential to interpreting SIP signaling procedures.
Huawei reference: Training Material, PDF pages 100-101, SIP Requests (1) and SIP Requests (2).
NEW QUESTION # 26
After the IdeaHub is powered on for the first time, restored to factory settings, or restarted, the startup wizard screen is shown by default.
Answer: B
Explanation:
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.
Huawei reference: Training Material, PDF pages 328-334, Initial Configuration Description and Configuring the Startup Wizard.
NEW QUESTION # 27
After a video conference has been recorded, users are unable to replay the conference recording in the recording & streaming server's web interface.
Which of the following is not a possible cause?
Answer: A
Explanation:
Huawei's recording and streaming server (RSE) provides recording storage, video-on-demand (VOD), live streaming, and access-control capabilities. Once conference recording is complete, the recorded media is stored on the RSE and can be accessed through its web interface, subject to publication status and user permissions.
Option B is correct because disconnecting the RSE from the Service Management Center (SMC) after recording does not inherently prevent playback of video files already stored on the RSE. Provided that the RSE remains operational, its storage is accessible, and users can access its web interface, existing recordings can still be played.
Option A represents a possible cause because an administrator may remove a released recording from the available video list, preventing ordinary users from accessing it.
Option C is also a possible cause. Recordings placed in the to-be-released state are unavailable to users who require the recording to be published before viewing.
Option D is a possible cause because the RSE implements permission-based access control. Users cannot view recordings for which they lack the required authorization.
Huawei's Training Material distinguishes between released and to-be-released videos and explains the corresponding viewing permissions.
Huawei reference: Training Material, PDF pages 502-503, Watching a Video on Demand; pages 506-507, Releasing a Video. Lab Guide, Sections 4.7.8-4.7.10, Supporting Live Streaming and VOD, Releasing Recorded Programs, and Removing a Recorded Program.
