Which network security model eliminates implicit trust by requiring verification for every access request?

• A. Zero Trust
• B. Cross-Domain Connections
• C. Directory Services
• D. Federation of Identity (FIdM)

Answer: (A)

This question tests Zero Trust, a network security model built on “never trust, always verify.” In Zero Trust, no access is granted implicitly; every request is authenticated and authorized based on multiple factors—identity, device health, location, the sensitivity of the resource, and real-time risk. Policies are enforced at the point of access with least-privilege permissions and continuous verification, often with micro-segmentation and ongoing monitoring. The other concepts describe related ideas—trust relationships between domains, centralized identity data, or cross-domain single sign-on—but they do not require verification for every access request across the board the way Zero Trust does.
