Designing and Deploying Microsoft Exchange Server 2016 — Question 14

You have an Exchange Server 2016 organization.
You plan to configure the organization in a hybrid deployment.
You need to identify which firewall ports must be open for Microsoft Azure Active Directory Connect (Azure AD Connect) to communicate with Azure Active
Directory (Azure AD).
Which two TCP ports should you identify? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

Answer options

• A. 80
• B. 389
• C. 443
• D. 636
• E. 3289 AC

Correct answer:

Explanation

The correct ports for Azure AD Connect to communicate with Azure AD are TCP port 443 and port 80. Port 443 is used for secure HTTPS communication with Azure AD, while port 80 is used for initial HTTP communication. Ports 389 and 636 are related to LDAP directory services, and port 3289 AC is not relevant for Azure AD Connect operations.
