NEW QUESTION # 22
The VDC can be used with the Huawei video conferencing platform to provide rich conference control functions. Conference control settings can be customized, and conference control shortcut keys and descriptions can be set.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
The Huawei Video Conferencing Desktop Client (VDC) offers comprehensive conference-control capabilities, allowing you to tailor control settings and define custom shortcut keys with descriptive labels for streamlined operation.
NEW QUESTION # 23
The main functions of H.245 include capability negotiation, video encoding, and master-slave determination.
- A. FALSE
- B. TRUE
Answer: A
NEW QUESTION # 24
Which of the following statements is false about SVC intelligent forwarding conferences?
- A. In an SVC intelligent forwarding conference, the video resolution viewed by each participant varies depending on the endpoint bandwidth and capability of SVC participants.
- B. In an SVC intelligent forwarding conference, an SVC endpoint can send a maximum of six channels of video streams to the MCU.
- C. In an SVC intelligent forwarding conference, the Box 310/610 can join a conference with the SVC capability.
- D. When the MCU works in SFU mode, the SVC intelligent forwarding conference is supported.
Answer: B
Explanation:
In an SVC intelligent forwarding conference, SVC endpoints transmit up to four video channels (base plus enhancement layers) to the MCU for forwarding; they do not send six channels.
NEW QUESTION # 25
The Record-Route header field indicates the route of a request.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
The Record-Route header is inserted by proxies to advertise their desired route for subsequent requests in the dialog.
NEW QUESTION # 26
Assume endpoints T1 and T2 are registered with the same SC node zone. After T1 calls the number of T2 using H.323, T1 and T2 communicate with each other. Which of the following statements are true about the call process? (Choose all that apply.)
- A. In this process, the H.225 call signaling interaction between T1 and T2 must pass through the SC.
- B. Endpoint control signaling involved in this process mainly includes H.225 RAS, H.225 Call Signaling, and H.245.
- C. 225 RAS messages (registration, admission, status) always traverse the SC (gatekeeper) for endpoints in the same zone.
- D. In this process, the H.225 RAS signaling interaction between T1 and T2 must pass through the SC.
- E. In this process, the media stream must be directly transmitted between T1 and T2.
Answer: B,D,E
Explanation:
RTP media is exchanged directly between T1 and T2 once the call is established.
The call control sequence involves H.225 RAS (registration/admission), H.225 call signaling (SETUP/CONNECT), and H.245 control for capabilities.
NEW QUESTION # 27
In an SVC hybrid conference (scheduled on the SFU and IAU), when an AVC participant views continuous presence of an SVC participant, dynamic codec resources on the IAU are consumed. When an AVC participant views continuous presence of other AVC participants, no dynamic codec resources are consumed.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
Displaying SVC streams to AVC endpoints requires IAU decoding and encoding, consuming dynamic codec resources; forwarding native AVC streams uses SFU without engaging IAU resources.
NEW QUESTION # 28
Currently, the widely used video compression standards include H.263, H.264, H.265, MPEG-1, MPEG-2, and MPEG-4. The H.26X series standards are mainly used for real time video communication, and the MPEG series standards are mainly used for video storage (DVD), video broadcast, and video streaming media.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
The H.26x family (H.263, H.264/AVC, H.265/HEVC) was designed with low-latency, real-time encoding/decoding in mind (ideal for videoconferencing and streaming calls) whereas MPEG-1/2/4 were originally optimized for file-based storage (VCD/DVD), broadcast and progressive streaming. Modern deployments often blend these. For example, using H.265 for both live calls and high-efficiency streaming and newer standards (like H.266/VVC) are now emerging.
NEW QUESTION # 29
The new and old MCU architectures differ in bandwidth and codec resource usage during cascading. The new architecture supports multiple working modes, such as MCU, SFU, and IAU. The old architecture does not provide different working modes of the MCU. Which of the following statements is false about MCU cascading?
- A. When MCUs of the old architecture are cascaded, the cascading channel consumes bandwidth and codec resources.
- B. When the MCU of the old architecture is cascaded with the MCU of the new architecture, the proxy channel consumes bandwidth and codec resources.
- C. When MCUs of the new architecture are cascaded, both the cascading channel and proxy channel consume bandwidth and codec resources.
- D. When the MCU of the old architecture is cascaded with the MCU of the new architecture, the cascading channel consumes bandwidth and codec resources.
Answer: D
Explanation:
When cascading an old-architecture MCU with a new-architecture MCU, only the proxy channel on the new side consumes bandwidth and codec resources - the legacy MCU's cascading channel is not used.
NEW QUESTION # 30
The MCU debugging command "mswt-media config_info" is used to query the configuration information about media exchange.
- A. FALSE
- B. TRUE
Answer: A
Explanation:
The mswt-media config_info command displays static media configuration parameters; querying actual media-exchange status requires the mswt-media exchange_info command.
NEW QUESTION # 31
In a hybrid multistream conference, SVC and AVC endpoints can join the conference at the same time. By default, the system provides the same continuous presence experience as the AVC conference.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
In a hybrid multistream conference, the MCU's built-in media resources run in dual-mode (AVC+SVC) intelligent adaptation by default, and when SVC and AVC participants view each other, the system automatically delivers the same continuous-presence layout and experience as in an AVC (universal transcoding) conference.
NEW QUESTION # 32
In a SIP multipoint conference, if BFCP Trans Type is set to TCP on the MCU, the BFCP communication protocol must be set to TCP on the endpoint.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
BFCP transport must match between the MCU and endpoints; if the MCU is configured for TCP, endpoints must also use TCP for BFCP.
NEW QUESTION # 33
SIP and SDP are independent of each other. SIP can implement multimedia calls independently to add new applications or media easily.
- A. FALSE
- B. TRUE
Answer: A
Explanation:
SIP relies on SDP for session description in multimedia calls; it cannot negotiate media parameters independently of SDP.
NEW QUESTION # 34
Assume endpoints T1 and T2 are registered with the same SC node zone (signaling routing is enabled on the SC). After T1 calls the number of T2 using H.323, T1 communicates with T2. How many TCP connections are established in this process?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
With signaling routing enabled on the SC, both the H.225 call signaling and the H.245 control channel are each split into two TCP legs (T1→SC and SC→T2), resulting in 2 × 2 = 4 TCP connections.
NEW QUESTION # 35
A company deployed a new Huawei video conferencing system last year (conference rooms are managed by organization). Now, the company plans to add 50 Box 610 devices to meet service requirements. In addition, the company plans to change the conference room management mode to area management in the SMC system to meet their new conference room management requirements. In this case, before provisioning new conference rooms, you can directly click Organization Management to switch to Area Management on the SMC web interface.
- A. FALSE
- B. TRUE
Answer: A
Explanation:
You cannot directly switch from organization to area management when existing conference rooms are bound under organization management; you must first complete the migration process (such as unbinding or reassigning rooms) before the switch becomes available.
NEW QUESTION # 36
When the MCU has two service network ports, you can use the IP address bound to bond0 or bond1 to access the MCU web interface.
- A. FALSE
- B. TRUE
Answer: A
Explanation:
The MCU's web management interface listens only on the service-network bond (bond0); the second port group (bond1) is dedicated to media traffic and does not provide web access.
NEW QUESTION # 37
Assume the SMC system administrator wants to remotely log in to the SC in SSH mode. Which of the following is the default port for the admin user to log in to the SC?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
SSH uses port 22 by default for secure CLI access to the SC admin account.
