Designing and Implementing a Server Infrastructure — Question 21

You need to perform the directory synchronization with Office 365.
What should you do first?

Answer options

• A. Set the domain functional level to Windows Server 2012.
• B. Upgrade the Office 365 licenses to Enterprise E4.
• C. Set the forest functional level to Windows Server 2012.
• D. Create a site-to-site VPN.
• E. Install the DirSync utility in the on-premises environment.

Correct answer: D

Explanation

The correct answer is D because establishing a site-to-site VPN is crucial for secure communication between the on-premises environment and Office 365. The other options do not directly pertain to the initial setup required for directory synchronization, as they involve configurations or upgrades that are not prerequisites for starting the synchronization process.
