QuestionQ1

Recording & Streaming Products and Features

Which statement below is false regarding the video-download and network-storage capabilities of the recording & streaming server (RSE)?

  • A If a presentation video is attached to a conference recording, users can download the presentation video after being approved.
  • B Users can download online videos as required, including recorded conference videos.
  • C The RSE offers local disk storage and supports IP SAN storage network to store video files.
  • D The RSE offers local disk storage and supports the network file system (NFS) to store video files.
Explanation

The RSE supports local disk storage and IP SAN network storage for video files. NFS is supported for operations such as exporting, dumping, or uploading recorded files for backup, rather than as the RSE network-storage method for video-file storage.

QuestionQ2

Video Conferencing Technology and Product Overview

Which statement below is false regarding VMR conferences?

  • A Before participants can join a VMR conference, it must first be activated.
  • B Once a VMR is set up on the SMC, you can choose to make it a personal or public VMR before starting a conference on an endpoint.
  • C When adding a participant on the SMC, you can assign a VMR number to the endpoint directly.
  • D Each VMR number can only hold one conference at a time.
Explanation

SMC VMR conferencing uses the personal VMR mode, in which a fixed VMR number is allocated to and bound with a user account or conference device. It is not configured by choosing between personal and public VMR types.

QuestionQ3

SMC Products and Features

The SMC schedules and starts an H.323-only multipoint conference with four participants. After it receives the participant list, the MCU sends an ARQ message to the SC.

How many ACF messages will the SC send back in response to the ARQ message?

  • A 8
  • B 12
  • C 4
  • D 2
Explanation

For each H.323 participant call, the SC acting as the gatekeeper provides admission confirmation for the MCU’s outgoing call and for the called endpoint’s incoming-call admission. A four-participant multipoint conference therefore requires two ACF messages per participant, for a total of eight.

QuestionQ4

SMC Products and Features

The SMC manages MCUs as resources.

Which of the following statements are correct about MCU management and scheduling on the SMC?

Choose three
  • A On the SMC web interface, you can view the basic information, alarms, logs, configuration information, and usage of the MCU.
  • B You can add, modify, and delete MCUs on the SMC web interface.
  • C On the SMC, you can configure load balancing, sharing, as well as redundancy and backup of MCU resources.
  • D You can set the MCU working mode on the SMC.
Explanation

SMC2.0 provides centralized management of MCU systems, including web-based device status, alarm and log handling, configuration management, and MCU utilization reporting. It supports registering and managing MCU resources and grouping multiple MCUs into resource pools for centralized scheduling, enabling load balancing, sharing, and redundancy or backup. MCU working mode is configured on the MCU, not as an SMC MCU-resource scheduling setting.

QuestionQ5

MCU Products and Features

A company has deployed three MCUs within the same service area. When starting a conference, it needs to preferentially choose the MCU that has the greatest number of available ports for the conference connection.

Which feature is required to accomplish this?

  • A Load balancing
  • B Intra-pool backup
  • C Inter-pool backup
  • D Automatic cascading
Explanation

Load balancing selects an MCU for a new conference according to available capacity, allowing the MCU with the most available ports in the service area to be preferred. Backup features are for failover, and automatic cascading is for spanning conference resources across MCUs.
