A financial services company is experiencing intermittent one-way audio issues in conferences hosted on their Huawei VP9660 MCU. The issue primarily affects remote employees connecting via Huawei CloudLink clients over a VPN, while users on the corporate LAN with TE30 endpoints do not experience problems. A network analysis reveals that signaling packets (SIP) are traversing correctly, but RTP packets from the remote clients are not consistently reaching the MCU. Which of the following is the most probable root cause of this issue?

A collaboration engineer is designing a highly resilient video conferencing solution for a hospital's telehealth service. The key requirements are end-to-end encryption for all sessions and the ability for endpoints to automatically failover to a secondary gatekeeper if the primary becomes unavailable. Which combination of technologies and configurations must be implemented to meet these requirements? (Select TWO)

A university is deploying Huawei IdeaHubs in its lecture halls. To prevent unauthorized use, the IT department wants to ensure that only faculty members can initiate meetings and access advanced settings, while students can only join meetings and use basic whiteboarding features. Which Huawei platform is used to centrally define and enforce these distinct user roles and permissions across all IdeaHub devices?

True or False: In a Huawei video conferencing environment, Scalable Video Coding (SVC) allows an MCU to send a single, multi-layered video stream to all participants, where each endpoint decodes only the layers it can support based on its display resolution and available bandwidth.

An engineer is troubleshooting a SIP call failure between a Huawei CloudLink client and a third-party SIP endpoint. A packet capture shows the CloudLink client sending an INVITE request, and the third-party endpoint responding with a '488 Not Acceptable Here' message. What is the most common reason for receiving this specific SIP response code?

A company has two main offices, one in New York and one in London, each with its own Huawei VP9650 MCU. To optimize bandwidth usage over the transatlantic WAN link, they want to cascade the MCUs for large global meetings. An administrator has configured the cascading link, but participants in London report that they can only see the active speaker from New York, not the continuous presence layout. The network topology is shown below. What is the most likely configuration error? ```mermaid graph TD subgraph NewYork_Office NY_MCU[VP9650 MCU - NY] NY_EP1[TE Endpoint] NY_EP2[TE Endpoint] end subgraph London_Office LON_MCU[VP9650 MCU - LON] LON_EP1[TE Endpoint] LON_EP2[TE Endpoint] end NY_EP1 --> NY_MCU NY_EP2 --> NY_MCU LON_EP1 --> LON_MCU LON_EP2 --> LON_MCU NY_MCU -- Transatlantic WAN Link --- LON_MCU ```

A network administrator needs to reserve bandwidth for video conferencing traffic across the corporate WAN. To achieve this, they must mark the traffic with the appropriate Layer 3 QoS identifier. Which field in the IP header is used to carry Differentiated Services Code Point (DSCP) values?

To improve audio quality in a large, acoustically challenging boardroom, an AV specialist has installed multiple ceiling microphones. However, during conferences, participants complain of echo and a 'hollow' sound. Which audio processing feature on the Huawei video conferencing endpoint is specifically designed to mitigate these issues by differentiating between direct sound and reflected sound?

An administrator is performing a security hardening on a Huawei collaboration environment. What are the three primary mechanisms used to secure a SIP-based video conference session from eavesdropping and unauthorized access? (Select THREE)

A manufacturing company is setting up a video link between its design center and a factory floor. The design center has a high-resolution Huawei TE60 endpoint in a pristine studio environment. The factory floor has a ruggedized mobile video cart with a lower-resolution camera and is subject to variable Wi-Fi connectivity. To ensure the best possible experience for both sides, which video technology should be prioritized on the central MCU?
