NEW QUESTION # 53
Assume that a user holds a multipoint conference using the Huawei video conferencing system. After a participant is unmuted and broadcast, the microphones of the remaining participants are automatically muted.
Which conference-control operation can the user perform on the SMC to produce this effect?
Answer: C
Explanation:
Huawei SMC provides conference-control functions that allow administrators to regulate participant audio, video, and presentation behavior during multipoint conferences.
The Giving the floor function assigns speaking priority to a selected participant. When this operation is performed, the selected participant's video is displayed to the other participants, and the microphones of the remaining participants are automatically muted.
Option C is therefore correct.
Option A, Free discussion, is intended to enable open interaction among participants. Huawei describes this function as unmuting participants and stopping the current broadcast, making it unsuitable for the scenario.
Option B, Locking a conference, restricts conference access or related operations according to the configured locking function. It does not implement the specific speaking-priority behavior described.
Option D, Muting all, applies microphone muting to participants collectively. It does not independently grant speaking priority and broadcast one selected participant while leaving that participant unmuted.
The Lab Guide explicitly describes Giving the floor as a conference-control operation in which other participants are muted and automatically view the specified participant.
This functionality is especially useful in formal meetings, presentations, administrative conferences, and other structured discussions where one participant must address the conference without interruption.

NEW QUESTION # 54
The SMC manages MCUs as resources.
Which of the following statements are correct about MCU management and scheduling on the SMC?
Choose three
Answer: A,B,D
Explanation:
Huawei's Service Management Center provides centralized MCU administration, resource management, scheduling, and operational monitoring. The SMC allows administrators to coordinate multiple MCUs and maintain conference availability without managing each conference connection individually.
Option A is correct because the SMC provides device-management capabilities covering configuration information, operational status, alarms, logs, and resource information. These functions allow administrators to inspect MCU health and diagnose service-related problems.
Option B is correct because administrators can perform MCU lifecycle management from the SMC web interface. The Training Material describes adding an MCU through Device Management > MCU. MCU configuration and registration parameters are centrally managed after the device is added.
Option C is also correct. Huawei supports MCU resource pools with load balancing, automatic cascading, and redundancy mechanisms. These capabilities improve resource utilization and conference reliability. When the primary MCU becomes unavailable, backup mechanisms can transfer conference services to another suitable MCU.
Option D is incorrect because the MCU working mode is configured through the MCU web interface. Huawei specifically describes MCU, SFU, and IAU operating modes as device-level configurations rather than SMC resource-scheduling settings.
The distinction is between centralized MCU resource administration and configuration of the MCU's internal media-processing mode.

NEW QUESTION # 55
In the CloudVC 23.0 solution, proprietary Super Error Concealment (SEC) technology ensures video quality even when the packet-loss rate reaches 30% and 12 consecutive packets are lost. It accomplishes this by using verification packets to respond to lost packets and implement video QoS.
Answer: A
Explanation:
Super Error Concealment (SEC) is Huawei's proprietary video-quality protection technology, designed to maintain acceptable video performance when packets are lost during network transmission.
Packet loss is particularly damaging to compressed video streams because missing packets may contain information required to decode individual frames or reconstruct subsequent frames. Depending on the affected data, packet loss can produce visible artifacts, interrupted motion, image freezing, or temporary deterioration of video quality.
Huawei's Training Material explicitly describes SEC as supporting video quality when packet loss reaches
30% and 12 consecutive packets are lost. This establishes the performance capability stated in the first part of the question.
The question additionally attributes this capability to verification packets used for packet recovery. Such recovery mechanisms are conceptually consistent with redundancy-based error protection, where additional information enables a receiver to reconstruct missing data.
However, the supplied Training Material does not specify the verification-packet algorithm or explicitly identify verification packets as the mechanism implementing SEC.
Verification finding: The performance figures are directly documented, but the asserted verification-packet mechanism is not independently established by either supplied guide. The intended answer is TRUE; the complete statement cannot be certified as fully verified from these sources alone.

NEW QUESTION # 56
If SMC provisions conference rooms by area, conference rooms can be linked only to areas and not to organizations.
Answer: A
Explanation:
Huawei Service Management Center (SMC) supports two conference-room provisioning approaches:
organization-based management and area-based management. These approaches determine how conference rooms are structured, administered, and made available to users.
When conference rooms are provisioned by organization, the Organization parameter is mandatory. This associates the conference room with a particular organizational structure and determines its visibility according to organizational permissions.
When conference rooms are provisioned by area, the Area parameter becomes mandatory. However, this does not prevent the conference room from also being associated with an organization.
Huawei's Training Material explicitly states that, under area-based provisioning, Area is mandatory and Organization is optional.
Therefore, the statement is false.
Area-based conference rooms are normally treated as public resources available to users across the system.
Nevertheless, an administrator can optionally specify an organizational association during provisioning.
Option A is incorrect because it assumes that area-based provisioning prohibits organizational associations.
Option B is correct because Huawei permits conference rooms to be linked to an area while also retaining an optional organization association.
This distinction is particularly important in enterprises that use geographical areas for conference-room resource allocation while maintaining organizational information for administrative purposes.
Huawei reference: Training Material, PDF pages 615-616, Organization and Area; PDF page 622, Provisioning a Conference Room (1). Lab Guide, Section 3.5.2, Provisioning Conference Rooms.
NEW QUESTION # 57
After conference rooms have been provisioned on the SMC, which settings must be configured on manageable endpoints?
Choose two
Answer: C,D
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.
