NetNTLM responses are used in which authentication protocol?

• A. NTLM
• B. Kerberos
• C. OAuth
• D. SAML

Answer: (A)

NetNTLM responses belong to the NTLM authentication protocol, which uses a challenge–response exchange to prove knowledge of the user’s password without sending it directly. In this flow, the server issues a random challenge, and the client replies with a NetNTLM response computed from the user’s password hash. The server then validates that response to authenticate the user. Kerberos relies on tickets rather than NetNTLM responses, while OAuth and SAML are token-based web authentication methods that operate differently. So NetNTLM responses are specifically used in the NTLM protocol.
