Exam SC-400 topic 1 question 35 discussion

The change you need to do is : - disable the double encryption - User access to content expires is set to a value other than Never.

1. Selecting Double encryption does not cause any issue with co-authoring files. 2. Other options like "Assign permissions now" , "Assign Permissions to specific users and groups" are already selected. 3. Use access to content expires - does not effect co-authoring files. Then the steps that are left: Select "Assign Permissions to specific users and groups" --> Assign Permissions Then Select User or groups to select users to whom co-authoring can be provided These are the two steps that have to be performed. There are no multiple choices here.

there is another option now, see: https://learn.microsoft.com/en-us/purview/sensitivity-labels-coauthoring?view=o365-worldwide%20https%3A%2F%2Ftechcommunity.microsoft.com%2Ft5%2Fsecurity-compliance-and-identity%2Fco-authoring-files-with-sensitivity-labels%2Fba-p%2F3029768

I agree with others in this discussion. Set expiration to never and turn off double encryption. Note: The question starts with "You plan to enable co-authoring of encrypted files".... If it's not enabled now, setting these configurations on a sensitivity label won't accomplish that. You need to make a bigger change that can affect your entire enterprise. Make sure you're familiar with this in prep for the test. https://learn.microsoft.com/en-us/microsoft-365/compliance/sensitivity-labels-coauthoring?view=o365-worldwide
