NEW QUESTION # 22
Which of these statements are true about the VP9800-T series MCU?
Choose three
Answer: A,B,C
Explanation:
Huawei's VP9800-T series provides high-capacity media-processing functions that support AVC universal transcoding and SVC multistream forwarding within a converged MCU architecture.
Option A is correct. The Training Material specifies that VP9830-T, VP9850-T, and VP9860-T support up to
300 concurrent 1080p30 forwarding connections through the electrical-port configuration, subject to the documented operating conditions.
Option B is correct because the VP9830-T supports 64 concurrent 1080p30 participants in universal transcoding mode. The MCU uses its media-processing resources to accommodate participants requiring different media characteristics.
Option C is correct because the VP9800-T series supports H.265 4K universal transcoding and SVC multistream forwarding. These capabilities allow the MCU to support both high-quality traditional video conferences and bandwidth-efficient scalable video services.
Option D is incorrect. Huawei identifies the VP9800-T series as using its Kunpeng-based hardware architecture, rather than the dedicated x86 architecture specified in the option.
This distinction is important because Huawei offers different MCU product families with different hardware platforms.
Direct source confirmation: Huawei includes an equivalent multiple-answer question in the MCU module's own quiz and supplies the answer corresponding to these same three capabilities.
Huawei reference: Training Material, PDF page 41, VP9800(T) Series Fully-Converged Media Engine; PDF page 457, MCU Products and Features - Quiz, which explicitly supplies the equivalent answer.
NEW QUESTION # 23
After conference rooms have been provisioned on the SMC, which settings must be configured on manageable endpoints?
Choose two
Answer: A,B
Explanation:
Huawei manageable endpoints use an activation-based provisioning mechanism to establish communication with the Service Management Center. This mechanism simplifies endpoint deployment and enables centralized device-management services.
Option C is correct because the endpoint must identify the appropriate management server type. Setting the server type to SMC directs the endpoint to use Huawei's centralized service-management infrastructure.
Option D is also correct because the endpoint requires the SMC service IP address to establish communication with the management platform.
The Lab Guide provides the exact configuration procedure. After provisioning a conference room, the administrator logs in to the endpoint web interface and navigates to System Settings > Server > Basic Services. The administrator then configures the server type, server address, and activation code before activating the endpoint.
Option A is not the expected answer. Although Huawei's endpoint-management architecture uses TR-069- related mechanisms, manually configuring TR-069 parameters is not one of the two requested settings in this provisioning procedure.
Option B is incorrect because SNMP configuration is not required for the described activation workflow.
Important configuration detail: The actual Huawei procedure also requires the activation code allocated by the SMC. It is an additional mandatory value omitted from the answer choices. Consequently, C and D are the two correct listed selections, but they do not constitute the complete endpoint activation configuration.
Huawei reference: Lab Guide, Section 3.5.3, Activating Endpoints, PDF pages 84-85; Training Material, PDF page 542, Automatic Endpoint Registration.
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
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 # 26
Which of these statements is true about the Q.931 call process?
Answer: D
Explanation:
The H.225/Q.931 call-signaling protocol is used in H.323 multimedia communication systems to establish, manage, and release calls between endpoints.
The typical call-signaling sequence is SETUP # CALL PROCEEDING # ALERTING # CONNECT # RELEASE COMPLETE.
SETUP initiates the call and carries information identifying the calling and called parties.
CALL PROCEEDING indicates that the called endpoint has received the call request and is processing it.
Huawei identifies this as optional signaling during the call-establishment phase.
ALERTING indicates that the called endpoint is alerting the user, typically corresponding to the ringing phase of the call.
CONNECT indicates that the called endpoint has accepted the call. This message confirms successful call establishment.
RELEASE COMPLETE is exchanged during call termination to indicate completion of the release procedure.
Option B is correct because it follows the sequence documented in Huawei's H.225/Q.931 signaling diagrams.
Option A incorrectly places ALERTING before CALL PROCEEDING. Options C and D incorrectly place CONNECT before the normal call-processing and alerting stages.
Although the precise signaling sequence can omit optional messages in particular call scenarios, the standard sequence presented in the Huawei course follows option B.
Understanding this progression is important when diagnosing H.323 call-establishment failures and interpreting endpoint signaling traces.
Huawei reference: Training Material, PDF pages 138-141, H.225/Q.931 Call Signaling (1), (2), and the associated signaling-flow diagrams.
