NEW QUESTION # 15
Which statement correctly describes the functions of the RTP protocol?
Answer: B
Explanation:
Real-time Transport Protocol (RTP) is responsible for transporting time-sensitive media streams, including audio and video, across IP networks.
RTP provides mechanisms such as sequence numbering and timestamps that allow receiving endpoints to identify packet ordering and support the timely reconstruction and playback of real-time media.
Option C is correct because RTP is the protocol used to carry real-time media streams within an established multimedia communication session.
Option A describes the role of Session Description Protocol (SDP). SDP communicates media characteristics and negotiation information, including supported codecs, transport addresses, and media parameters.
Option B describes Session Initiation Protocol (SIP). SIP is responsible for initiating, modifying, and terminating communication sessions through signaling messages.
Option D describes Real-time Transport Control Protocol (RTCP). RTCP works alongside RTP to monitor media-stream transmission characteristics and provide control information, including reception statistics and quality-related feedback.
Huawei's Training Material explicitly distinguishes these protocol responsibilities in its introduction to SIP.
An important technical distinction is that RTP supports real-time delivery mechanisms but does not independently guarantee packet delivery, eliminate network congestion, or ensure a fixed transmission delay.
Overall media quality depends on the network and associated quality-control mechanisms.
Huawei reference: Training Material, PDF pages 93-94, Location of SIP on the Network and Introduction to SIP (1).
NEW QUESTION # 16
Which of these statements are true about the VP9800-T series MCU?
Choose three
Answer: A,C,D
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 # 17
Which IdeaHub ES2 Pro function lets you open two applications at the same time in split-screen mode, reducing the need for complex app switching and improving usage efficiency?
Answer: D
Explanation:
Huawei IdeaHub ES2 Pro includes a Multi-Window capability that allows users to operate two supported applications simultaneously on the same screen.
Multi-Window divides the IdeaHub display into separate application areas, enabling users to work with different types of content without repeatedly switching between applications.
For example, users can review presentation materials in one window while writing notes or collaborating on the electronic whiteboard in another. Huawei supports adjustable split-screen ratios, including 1:1, 1:2, and 2:
1, to accommodate different application requirements.
Option B is correct because Multi-Window is explicitly designed for simultaneous multi-application operation.
Option A, Bulletin board, is used for displaying and managing informational content rather than running two applications side by side.
Option C, App Multiplier, is a different functionality. It allows a single compatible application to display multiple views or pages simultaneously, such as a navigation pane alongside a detailed content pane.
Option D, Dual-screen display, concerns displaying content across physical screens rather than dividing one display into separate application windows.
The defining distinction is that Multi-Window supports two applications concurrently, whereas App Multiplier presents multiple views of an individual application.

NEW QUESTION # 18
After signing in, which of the following menus can a common user use?
Choose three
Answer: B,C,D
Explanation:
Huawei SMC provides different conference portal interfaces according to the role assigned to the authenticated user. Common users have access to personal conference scheduling, conference templates, conference records, and user-level conference settings.
Option B is correct because common users can schedule conferences through the conference portal. The supported conference types include instant, scheduled, and recurring conferences, subject to the user's permissions and available resources.
Option C represents a supported capability because common users can view and manage scheduled conferences associated with their accounts. Huawei's role-permission documentation explicitly includes viewing scheduled and historical conferences among common-user capabilities.
Option D is correct because common users can access their default conference parameters. These settings allow users to customize applicable conferencing preferences without changing system-wide defaults.
Option A is not part of the common-user navigation shown in the supplied Training Material. The dedicated Active Conferences menu appears in the conference administrator interface.
Verification concern: Huawei's common-user portal screenshot identifies My Conferences rather than a separate Scheduled Conferences navigation menu. Therefore, option C describes an available function but does not reproduce the exact menu label shown in the V4.0 interface. The intended answer is B, C, D, but the question should be corrected if exact menu names are being tested.

NEW QUESTION # 19
After conference rooms have been provisioned on the SMC, which settings must be configured on manageable endpoints?
Choose two
Answer: B,C
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.
