When configuring an AD synchronization task, which directory service is referenced?

• A. LDAP
• B. Active Directory
• C. DNS
• D. RADIUS

Answer: (B)

When configuring an AD synchronization task, you reference the directory service that stores identity information for your Windows environment. The directory service in question is Microsoft Active Directory, specifically Active Directory Domain Services, which holds user accounts, groups, and computer accounts across domains. LDAP is the protocol often used to access directory data, but the task is about the directory service itself, not the protocol. DNS handles name resolution, and RADIUS deals with network access authentication, neither of which serves as the directory of user identities. So the correct reference is Active Directory.
