What should you do to prepare attendees for a video conference?

To prepare attendees for a video conference, testing their internet connection is crucial. A stable internet connection is fundamental for ensuring clear audio and video during the conference. If participants have connectivity issues, it can lead to disruptions, confusion, and a lack of engagement during the session. By checking the internet connection beforehand, you can help attendees troubleshoot any problems they might encounter, allowing for a smoother and more productive meeting experience.

The other choices, while potentially beneficial in specific contexts, do not address the immediate technical requirements necessary for a successful video conference. Sharing a survey link might help gather feedback post-conference, requesting a dress code can help with professional appearance but is less critical for the operation of the conference itself, and confirming lunch orders may only be relevant if the video conference is part of a larger in-person event with catering, which is not inherently linked to the virtual aspect.
