Hosts or cohosts in meetings/webinars have the ability to create polls to use and share questionnaires.
To use polls in a meeting, turn polling on by going to Advanced Options > Scheduling Options > Meeting Options or Advanced Options > Scheduling Options > Webinar Options.
During your meeting, select View > Panels > Manage Panels, then select Polling > Add > OK.
From there, you can select the ellipsis and select Polling. You can then select the question type from the drop-down list in the Question section (Short Answer, Multiple Choice - Multiple Answer, Multiple Choice - Single Answer).
Click New to create a new question - and fill in the appropriate questions and answer sections! From there, you select your poll and click Open Poll to present to your attendees.
To end the poll, click Close Poll and you can the view Quick reference tasks to view options on how to save, share, and view poll results.
