NEW QUESTION # 15
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 new architecture are cascaded, both the cascading channel and proxy channel consume bandwidth and codec resources.
- B. When the MCU of the old architecture is cascaded with the MCU of the new architecture, the cascading channel consumes bandwidth and codec resources.
- C. When MCUs of the old architecture are cascaded, the cascading channel consumes bandwidth and codec resources.
- D. When the MCU of the old architecture is cascaded with the MCU of the new architecture, the proxy channel consumes bandwidth and codec resources.
Answer: B
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 # 21
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. Another participant whose speaker is turned off is at the local site.
- B. The microphone is too close to the speaker.
- C. The endpoint's input volume is lower than the minimum energy threshold required for echo cancellation.
- D. An audio loop exists. The external audio device feeds back the sound from the endpoint output port to the endpoint input port.
Answer: B,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.
NEW QUESTION # 22
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 # 23
In the collaboration solution architecture, which of the following network elements are deployed at the media processing layer? (Choose all that apply.)
- A. SMC
- B. VP9860
- C. CloudRSE
- D. Box 310
Answer: B,C
Explanation:
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.
NEW QUESTION # 24
In the encrypted conference scenario, the SIP transmission type must be set to TLS on both the MCU and endpoint.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
To secure SIP signaling in an encrypted conference, both the MCU and endpoints must use TLS as the transport for SIP messages.
NEW QUESTION # 25
At an SMC video conferencing system site, the customer wants to deploy a conferencing system with converged firewall ports, with a planned DMZ. The SC1 is deployed on the intranet and SC2 is deployed in the DMZ. In this case, which of the following deployment modes is the most suitable one for SC1 and SC2?
- A. SC1 is the proxy SC, and SC2 is the registration SC.
- B. SC1 and SC2 are both registration SCs.
- C. SC1 and SC2 are both proxy SCs.
- D. SC1 is the registration SC, and SC2 is the proxy SC.
Answer: D
Explanation:
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.
NEW QUESTION # 26

SIP relies on SDP for session description in multimedia calls; it cannot negotiate media parameters independently of SDP.
NEW QUESTION # 32
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: A
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 # 33
Which of the following statements is true about image sampling?
- A. The transmission rate of video data using YUV 4:2:0 is 140 Mbit/s. If the 4:2:2 mode is used, the transmission rate required by the video is 175 Mbit/s.
- B. For human eyes, the Y component in YUV is the most important. Therefore, downsampling can be performed on the UV components.
- C. The YUV 4:2:0 sampling mode is half the size of the YUV 4:4:4 sampling mode.
- D. RGB components have weak correlation, which is unfavorable for video image compression. Therefore, RGB is often used for image display.
Answer: C
Explanation:
YUV 4:2:0 subsamples chroma by a factor of two in both horizontal and vertical dimensions, reducing total data to half of the full-resolution YUV 4:4:4 format.
