NEW QUESTION # 20
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. Endpoint control signaling involved in this process mainly includes H.225 RAS, H.225 Call Signaling, and H.245.
- B. In this process, the H.225 call signaling interaction between T1 and T2 must pass through the SC.
- C. 225 RAS messages (registration, admission, status) always traverse the SC (gatekeeper) for endpoints in the same zone.
- D. In this process, the media stream must be directly transmitted between T1 and T2.
- E. In this process, the H.225 RAS signaling interaction between T1 and T2 must pass through the SC.
Answer: A,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 # 21
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. TRUE
- B. FALSE
Answer: B
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 # 22

Huawei's SMC supports cascading up to four conference levels for multi-level conferencing, ensuring efficient management and control across up to four tiers.
NEW QUESTION # 23
Which of the following statements are true about the SC cluster reconstruction deployment scenario? (Choose all that apply.)
- A. If the number of SIP endpoints is far less than that of H.323 endpoints, you are advised not to deploy the SC cluster.
- B. If the number of SIP endpoints is much greater than that of H.323 endpoints, an SC cluster can be deployed for SIP endpoint access. The non-cluster registration SC is reserved for H.323 endpoint access.
- C. If the number of connected extranet soft clients is greater than 2000, you are advised to reconstruct a non-cluster proxy SC into a proxy SC cluster.
- D. If the number of SIP endpoints is much greater than that of H.323 endpoints, an SC cluster can be deployed for SIP and H.323 endpoint access.
Answer: A,B,C
Explanation:
When SIP endpoints greatly outnumber H.323 endpoints, you deploy an SC cluster to serve the SIP devices while leaving a standalone SC for the H.323 endpoints.
If SIP registrations are much fewer than H.323 registrations, clustering the SC for SIP isn't recommended, as the scale doesn't justify the added complexity.
A proxy SC supports up to 2,000 external soft-client registrations; if you exceed this, you should rebuild it as a proxy-SC cluster to handle the extra load.
NEW QUESTION # 24
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. TRUE
- B. FALSE
Answer: A
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 # 25
In the non-DMZ public-private network traversal scenario (small- and medium-sized network where the SMC and SC are co-deployed), you need to configure the LAN2 port of the SC as the default routing port.
- A. TRUE
- B. FALSE
Answer: B
Explanation:
In a co-deployed small/medium network, LAN1 is used for the default gateway to the SMC/public network; LAN2 serves the private segment, so you do not set LAN2 as the default routing port.
NEW QUESTION # 26
In the SIP protocol, the Via header field indicates the route of the subsequent response message.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
The Via header tracks each hop of the request and is used to guide the response back along the same path.
NEW QUESTION # 27

- A. sc
- B. gauss
- C. root
- D. vcexpert
Answer: B
Explanation:
The SC's underlying database is a GaussDB cluster, and only the dedicated database OS user (gauss) has the necessary permissions to start and stop it using the GaussDB control utilities.
NEW QUESTION # 28

NEW QUESTION # 29
SIP is an application-layer protocol independent of the transport-layer protocols. It can be carried over different transport protocols, such as UDP, TCP, TLS, and SCTP. Currently, SCTP is the most commonly used transport-layer protocol.
- A. TRUE
- B. FALSE
Answer: B
Explanation:
While SIP is transport-agnostic and can run over UDP, TCP, TLS, or SCTP, UDP remains the predominant transport - SCTP is not the most commonly used.

- A. Bit rates of all ongoing streams
- B. Current system information of the CloudMCU
- C. MCU operation logs
- D. Conference and participant numbers of the ongoing conferences on the MCU
Answer: A
Explanation:
The mswt-media allflow command reports the bit rates of all ongoing media streams on the CloudMCU; it does not display conference/participant counts, system info, or logs.
NEW QUESTION # 31
Which of the following statements is false about point-to-point calls?
- A. During a point-to-point call, the Alerting signaling is used during the H.225/RAS connection.
- B. During a point-to-point call, the GK receives two call requests.
- C. During a point-to-point call, the called endpoint sends a call request to the GK after receiving a SETUP message.
- D. During a point-to-point call, H.245 performs capability set matching before the logical channel is opened.
Answer: A
Explanation:
Alerting is part of the H.225 call-signaling sequence, not the RAS interface, so it is not used over the RAS channel.
NEW QUESTION # 32

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. TRUE
- B. FALSE
Answer: B
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 # 35
An AVC conference is scheduled on the CloudMCU (working in SFU mode) and VP9850 (working in IAU mode). After the conf get strmInfo 41353221 command is executed on the CloudMCU, the following information is displayed:
Which of the following is the video stream number generated after the IAU decodes and re-encodes the three video streams of Site (16), Site (17), and Site (18)?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
In SFU+IAU mode, the IAU's re-encoded (decoded and encoded) streams are identified by the MpAdaptStrmNo value under Site(18). In the output, MpAdaptStrmNo[2710124429803] is the stream number carrying all three re-encoded video channels.
NEW QUESTION # 36
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. TRUE
- B. FALSE
Answer: A
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 # 40
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. TRUE
- B. FALSE
Answer: A
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 # 41
