You purchase a Microsoft 365 subscription.
You plan to move to Microsoft 365 and to implement a hybrid deployment solution for the next 12 months.
You need to prepare for the planned move to Microsoft 365.

Answer options

• A. Purchase a third-party X.509 certificate.
• B. Create an external forest trust.
• C. Rename the Active Directory forest.
• D. Purchase a custom domain name.

Correct answer: D

Explanation

The best action is to purchase a custom domain name, as it is essential for the Microsoft 365 setup and will allow for proper email routing and user identification. The other options, while potentially useful, do not directly impact the initial steps needed for directory synchronization in a Microsoft 365 hybrid deployment.
