Which of the following statements are true about the intranet-only SC cluster network? (Choose all
that apply.)
A, B, C, D
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.
H.323 endpoints must register with a standalone SC when an intranet-only cluster is used.
Deploying an intranet registration SC cluster is recommended when there are large numbers of SIP
hard or soft endpoints.

The stream transmission speed of a digitalized 1080p 60 fps analog TV signal is around
____________ Mbit/s. (Assume that a pixel is 24-bit and enter an integer.)
2986
Explanation:
Uncompressed 1080p at 60 fps has 1920 × 1080 = 2,073,600 pixels per frame. At 24 bits per pixel,
that’s 2,073,600 × 24 = 49,766,400 bits per frame. Multiplied by 60 fps gives 2,985,984,000 bit/s,
which is approximately 2986 Mbit/s.
FILL BLANK
The SMC small- and medium-sized network (SMC and SC co-deployed) supports a maximum of
____________ concurrent calls. (Enter Arabic numerals.)
1000
Explanation:
In a small- and medium-sized deployment with SMC and SC co-deployed on the same server, a single
device supports up to 1,000 concurrent calls.
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, B
Explanation:
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.
In a Huawei video conference, which of the following may cause echoes or even high-pitched noises
when the local participant speaks? (Choose all that apply.)
A, C, D
Explanation:
If the input volume falls below the echo canceller’s detection threshold, the device can’t identify and
suppress return audio, leading to echoes or squealing.
An audio loop, where output is fed back into the input, directly causes echo and feedback noise.
Placing the microphone too close to the speaker allows direct pickup of its output, resulting in echo
and potential high-pitched feedback.
In the encrypted conference scenario, the SIP transmission type must be set to TLS on both the MCU
and endpoint.
A
Explanation:
To secure SIP signaling in an encrypted conference, both the MCU and endpoints must use TLS as the
transport for SIP messages.
Which of the following information is displayed when you run the CloudMCU debugging command
“mswt-media allflow”?
D
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.
Which of the following conference parameters need to be obtained by engineers when locating
conference faults on the SMC video conferencing system? (Choose all that apply.)
A, B, C, D
Explanation:
When troubleshooting conferences, engineers must know the video protocol in use, the conference
type, the resolution and frame rate being delivered, and the bandwidth allocation - each of these
parameters directly impacts session behavior and helps pinpoint faults.
The MCU debugging command “mswt-media config_info” is used to query the configuration
information about media exchange.
B
Explanation:
The mswt-media config_info command displays static media configuration parameters; querying
actual media-exchange status requires the mswt-media exchange_info command.
Which of the following NEs’ information cannot be collected using the diagnostic information
collection function (Maintenance > Diagnostic Info Collection) on the SMC web interface?
C
Explanation:
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.
Which of the following permissions are granted to an SMC system administrator? (Choose all that
apply.)
C, D
Explanation:
The System Administrator role grants full privileges for system configuration tasks and for managing
administrator user accounts; it does not include conference or room management functions.
By default, the SMC provides six user roles. Default permissions of each user role can be modified or
deleted based on site requirements.
B
Explanation:
The SMC indeed provides six built-in user roles (system administrator, security administrator, security
auditor, program administrator, conference administrator, and common user), but their default
permissions are fixed and cannot be modified or removed.
Which of the following is the format of the configuration file exported from the CloudRSE web
interface?
D
Explanation:
The CloudRSE web interface exports its configuration in XML format, producing a .xml file for import
or backup.
The SMC system O&M engineer John wants to start and stop the SC database (version
V600R019C10SPCb20 or later). Which of the following user roles can be used to perform such
operations on the database?
A
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.
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.
B
Explanation:
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.
