Hi Jun,
Thank you for reaching out to Microsoft Q & A forum.
The correct answer for the exercise is that guest users can manage their profile, change their password, and retrieve some information about users, groups, and apps. The second option is correct, but in practice, their access depends on Microsoft Entra’s external collaboration settings, which may impose further restrictions. For the most accurate information, I recommend reviewing your organization's Entra settings.
