Synchronization is a critical aspect of Microsoft 365 Identity and Services. Understanding the prerequisites including connectivity methods, permissions, and server requirements is integral to mastering this aspect of the MS-100 exam.

Table of Contents

1. Connectivity Method

When working with Microsoft 365, two primary connectivity methods can be used for synchronization: ExpressRoute and Azure AD Connect.

ExpressRoute:

This is a dedicated network connectivity method between on-premises networks and Azure. It guarantees high availability and minimal latency. Using ExpressRoute avoids passing data through the public internet, thus enhancing security.

Azure AD Connect:

The Azure AD Connect involves integrating your on-premises directories with Azure Active Directory. With this tool, users can manage their Azure services from an on-premises Windows Server Active Directory.

2. Permissions

Properly configured permissions are at the heart of secure and effective synchronization. The two types of permissions to pay keen attention to in Microsoft 365 are: Service administrator and global administrator.

Service Administrator:

They have access to all features within a single service but cannot access or perform operations within another service. An example would be a SharePoint administrator who wouldn’t have access to Exchange services.

Global Administrator:

These can access all administrative features. This is the highest level of permissions and is applied to those who set up the Microsoft 365 or Office 365 account.

3. Server Requirements

Setting up synchronization also demands a carefully-optimized server landscape. Key server requirements include:

  • Azure AD Connect Server: This can be deployed on any member server that’s running Windows Server 2008 or later. However, it’s preferable to use Windows Server 2012 R2 or later.
  • Domain Server: The domain server used should be running Windows Server 2008 R2 or higher.
  • SQL Server: SQL Server 2012 or later is recommended. Full SQL Server installation is supported but isn’t required.
Parameter Requirement
Azure AD Connect Server Windows Server 2008 or higher
Domain Server Windows Server 2008 R2 or higher
SQL Server SQL Server 2012 or higher

In conclusion, understanding the prerequisites of synchronization – connectivity method, permissions, and server requirements – is key to your success in the MS-100 Microsoft 365 Identity and Services exam, and important for the effective management of any Microsoft 365 installation. Always remember to go through the latest official documentation and resources from Microsoft for the most up-to-date and in-depth understanding.
