Who has the authority to switch the authentication type to JWT for a FDI instance?

• A. Service administrator
• B. End user
• C. Application developer
• D. Auditor

Answer: (A)

Switching the authentication method is a security-oriented configuration change that affects how every client proves its identity to the FDI instance. This kind of setting is managed by someone with full service administration privileges, who has the authority to alter security and authentication configurations, rotate keys, and manage tokens. The service administrator is responsible for these critical controls, so they are the ones who would switch the authentication type to JWT.

End users rely on the existing authentication setup and cannot modify security mechanisms. Application developers might implement clients that use JWT, but they don’t usually have the power to change the server’s authentication method. Auditors review and verify configurations and activity, not change them.
