Explanation

AD (Active Directory) server is a directory server because Active Directory is Microsoft's implementation of LDAP-based directory services - it stores and organizes information about network resources (users, computers, groups, policies) in a hierarchical, searchable structure, which is exactly what a directory server does.

Why the distractors are wrong:

• A. RADIUS server - handles authentication, authorization, and accounting (AAA) for network access, not directory storage.
• C. DNS server - resolves domain names to IP addresses; it's a name resolution service, not a general-purpose directory.
• D. Portal server - provides a web-based gateway/interface (like a captive portal for Wi-Fi login), not a directory.

Memory tip: Think "AD = Address Directory" - Active Directory is literally a directory of addresses and identities for everything on a Windows network, just like a phone directory stores names and numbers.
