Explanation

Centrally Managed Users (CMU) integrates database or system user management with a central directory service (such as Microsoft Active Directory), and it supports exactly three authentication mechanisms: Remote Access Services authentication (A), Kerberos authentication (D), and username/password authentication (E). These three align with how a directory service verifies identities - via delegated remote authentication, ticket-based network authentication, and direct credential validation, respectively.

Why the distractors are wrong:

• B (Smart key) - "Smart key" is not a recognized CMU authentication category; smart card/token-based auth falls under PKI, not a standalone method here.
• C (PKI/PKT) - Note the typo "PKT" is itself a red flag. While PKI exists in broader security contexts, it is not one of the three defined CMU authentication methods in this framework.
• F (SSH) - SSH is a transport/connection protocol, not an authentication method that CMU manages directly; conflating the two is a common exam trap.

Memory tip: Think "RKU" - Remote Access, Kerberos, Username/password. These are the three practical ways a centrally managed user can prove their identity: by delegating to a remote service, using a Kerberos ticket from a domain controller, or simply providing credentials. If it sounds more like a protocol (SSH) or a hardware token concept (smart key), it's not on the CMU list.
