Exam MS-721 topic 1 question 77 discussion

I think D is correct because you can bulk change the value of "Join third-party meetings" see ref: https://learn.microsoft.com/en-us/microsoftteams/rooms/rooms-manage Join third-party meetings = Direct Guest Join "Also Microsoft Teams Rooms devices support a one-touch experience for joining third-party online meetings, also referred to as Direct Guest Join" ref: https://learn.microsoft.com/en-us/microsoftteams/rooms/third-party-join

Why the Other Options Are Not Correct: A. From the Microsoft Teams admin center, select all the devices, and then add a tag: Adding a tag to devices helps with organizing and managing devices in groups but does not directly configure settings like Direct Guest Join. C. Run the Set-CsTeamsGuestMeetingConfiguration cmdlet: This cmdlet is used for configuring guest meeting settings at the tenant level but is not specifically for enabling Direct Guest Join on Teams Rooms devices. D. From the Microsoft Teams admin center, select all the devices, and then modify the Meeting settings: While you can modify meeting settings directly, this would be a manual process for each device and would not be as efficient as using a configuration policy.

B. From the Microsoft Teams admin center, configure a configuration policy.
