Show answer and explanation
Correct answers: A, B, D, E
Explanation
Endpoints and media types are critical to the performance of video conferencing systems. Network bandwidth, media type compatibility, supported codecs, and application updates are all important factors to verify when troubleshooting issues like poor video quality and audio lag. While hardware upgrades may improve performance, they are not a necessary step unless the current hardware is incompatible.
- A. Correct.
Verifying the network bandwidth and connectivity ensures that the endpoints have sufficient resources to handle video and audio streams without quality degradation.
- B. Correct.
Checking media type compatibility ensures that the video conferencing application and endpoints can process the video and audio streams correctly.
- C. Incorrect.
Upgrading all endpoints to the latest hardware is unnecessary unless the current hardware is incompatible. This step would not directly address the issue at hand.
- D. Correct.
Confirming supported codecs ensures that the endpoints and application can encode and decode the video and audio streams effectively, avoiding issues like lag and poor quality.
- E. Correct.
Ensuring that the application is updated can resolve compatibility bugs and improve performance during video conferencing.
