You Are Using Google Cloud Directory Sync to Manage Users

You are using Google Cloud Directory Sync to manage users. You performed an initial sync of nearly 1,000 mailing lists to Google Groups with Google Cloud Directory Sync and now are planning to manage groups directly from Google. Over half the groups have been configured with incorrect settings, including who can post, who can join, and which groups can have external members. You need to update groups to be configured correctly. What should you do?

A) Use the bulk upload with CSV feature in the G Suite Admin panel to update all Groups.
B) Update your configuration file and resync mailing lists with Google Cloud Directory Sync.
C) Create and assign a custom admin role for all group owners so they can update settings.
D) Use the Groups Settings API to update Google Groups with desired settings.
