質問 # 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
正解：B
解説：
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.
質問 # 32
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
正解：B
解説：
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.
質問 # 33
Which of the following information is displayed when you run the CloudMCU debugging command "mswt-media allflow"?
- A. Bit rates of all ongoing streams
- B. Conference and participant numbers of the ongoing conferences on the MCU
- C. Current system information of the CloudMCU
- D. MCU operation logs
正解：A
解説：
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.
質問 # 34
When the SMC is used to provision system administrator users, each user can be bound to an endpoint that is used as the conference joining device of the user.
- A. FALSE
- B. TRUE
正解：A
解説：
System administrator accounts in the SMC are management-only and do not support binding to endpoints for use as conference-joining devices; endpoint binding applies only to conference user or room accounts.
質問 # 35
By default, a single registration SC server supports a maximum of 20,000 registered devices.
- A. FALSE
- B. TRUE
正解：B
解説：
By default, a Registration SC server supports up to 20,000 registered devices, as specified in the Huawei SC product specifications.
質問 # 36
The MCU debugging command "mswt-media config_info" is used to query the configuration information about media exchange.
- A. FALSE
- B. TRUE
正解：A
解説：
The mswt-media config_info command displays static media configuration parameters; querying actual media-exchange status requires the mswt-media exchange_info command.
質問 # 37
Which of the following statements are true about personal virtual meeting room (VMR) provisioning?
- A. The SMC can provision personal VMRs to conference users one by one or in batches.
- B. The SMC can provision personal VMRs to conference rooms one by one or in batches.
- C. The SMC can provision personal VMRs to conference rooms only one by one.
- D. The SMC can provision personal VMRs to conference users only one by one.
正解：A、B
解説：
The SMC's service provisioning functions include both single-item and batch modes for personal VMR assignment, whether you're binding VMRs to conference rooms or to individual users, you can provision them one by one or import a list and provision them in bulk.
質問 # 38
Which of the following operations needs to be performed when you log in to the SC as the admin user using the CLI for the first time?
- A. Configure the SC IP address.
- B. Delete user configuration.
- C. Change the default password.
- D. Configure a default route for SC.
正解：C
解説：
On first CLI login, you must change the default admin password to secure the SC; other network settings can be configured as needed afterward.
質問 # 39
During a point-to-point call between different GKs, the local GK sends an LRQ request to the neighboring GK to query the information about the called node.
- A. FALSE
- B. TRUE
正解：B
解説：
In H.323, when a gatekeeper needs to locate an endpoint outside its zone, it issues a LocationRequest (LRQ) to the neighboring gatekeeper to retrieve the called party's address.
質問 # 40
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 much greater than that of H.323 endpoints, an SC cluster can be deployed for SIP and H.323 endpoint access.
- B. If the number of SIP endpoints is far less than that of H.323 endpoints, you are advised not to deploy the SC cluster.
- C. 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.
- D. 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.
正解：B、C、D
解説：
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.
質問 # 41
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, the Box 310/610 can join a conference with the SVC capability.
- C. When the MCU works in SFU mode, the SVC intelligent forwarding conference is supported.
- D. In an SVC intelligent forwarding conference, an SVC endpoint can send a maximum of six channels of video streams to the MCU.
正解：D
解説：
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.
質問 # 42
After an AVC conference is held, a user logs in to the MCU and runs the debug command. The following information is displayed:
Which of the following is the IP address of site T3?
- A. 172.23.132.76
- B. 172.23.133.116
- C. 172.23.133.115
- D. 172.17.64.65
正解：A
解説：
In the conference site list, Site 18 corresponds to T3 and its remote media IP ([RmtMedIp]) is listed as 172.23.132.76.
質問 # 43
Which of the following is the format of the configuration file exported from the CloudRSE web interface?
- A. .txt
- B. .bin
- C. .yml
- D. .xml
正解：D
解説：
The CloudRSE web interface exports its configuration in XML format, producing a .xml file for import or backup.
質問 # 44
Which of the following statements are true about the intranet-only SC cluster network? (Choose all that apply.)
- A. 323 endpoints must register with a standalone SC when an intranet-only cluster is used.
- B. If a large number of SIP hard endpoints or soft clients are located on the intranet, you can deploy a registration SC cluster on the intranet.
- C. A standalone SC should be deployed to provide registration services specifically for H.323 endpoints.
- D. The intranet registration SC cluster provides only SIP registration.
- E. The intranet SC cluster supports two distribution modes: single-active distribution and multi-active distribution.
正解：B、C、D、E
解説：
Deploying an intranet registration SC cluster is recommended when there are large numbers of SIP hard or soft endpoints.
Explanation:
An intranet-only SC cluster handles SIP registrations exclusively, offloading SIP endpoint load.
The cluster can be deployed in single-active or multi-active distribution modes for flexibility and redundancy.
質問 # 45
An endpoint is disconnected from a conference due to a power failure. After the endpoint is powered on again, it is not called to the conference again, and the SMC does not detect that the endpoint is disconnected. The SMC O&M engineer finds that this fault is caused by the "Timeout for hang-up upon no code streams" parameter on the CloudMCU. Which of the following parameter values may cause this fault? (Choose all that apply.)
- A. 0
- B. 1
- C. 2
- D. 3
正解：A、D
解説：
Setting the timeout to 0 or -1 disables the automatic hang-up when no media streams are received, so the MCU never tears down the call and SMC doesn't detect the endpoint has dropped.
