H11-861_V4.0 Sample Questions Answers

On first CLI login, you must change the default admin password to secure the SC; other network settings can be configured as needed afterward.

The mswt-media config_info command displays static media configuration parameters; querying actual media-exchange status requires the mswt-media exchange_info command.

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.

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.

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.

The Diagnostic Information Collection feature in the SMC web UI gathers logs and status from managed hardware network elements, such as SMC-connected SC nodes, RSE8800 recording engines, and Box 310 endpoints, by selecting their device types in Maintenance > Diagnostic Info Collection. It does not support collecting diagnostic data from software clients like Huawei CloudLink.

Only IDs within the configured range 9100000–9299999 are valid for new common conferences; 9288889 and 9100009 fall in this range, whereas 9688889 and 9300001 do not.

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.

To secure SIP signaling in an encrypted conference, both the MCU and endpoints must use TLS as the transport for SIP messages.

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.

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.

The media processing layer handles core media functions such as audio/video encoding, decoding, mixing, recording, and streaming. The VP9860 is Huawei’s MCU media server - deployed precisely in this media processing (media switching) layer to provide high-density encoding/decoding and mixing capabilities. CloudRSE (Cloud Recording & Streaming Engine) delivers recording and streaming services, which are also key media processing functions within this layer.

Deploying SC1 as the registration SC on the intranet allows internal endpoints to register directly, while placing SC2 as a proxy SC in the DMZ handles external signaling traversal and secures the demilitarized zone.

By default, a Registration SC server supports up to 20,000 registered devices, as specified in the Huawei SC product specifications.

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.
