1. Which security principle assumes that every request is a potential breach and
requires full authentication, authorization, and encryption?
A. Defense in Depth
B. Least Privilege Access
C. Zero Trust
D. Shared Responsibility
🟢 C. Zero Trust
🔴 Explanation: The Zero Trust model operates on the principle of "never trust, always
verify," requiring every access request to be fully validated regardless of its origin.
2. In the Shared Responsibility Model for Software as a Service (SaaS), who is

attacks in real time?
A. Verify Explicitly
B. Use Least Privilege Access
C. Assume Breach
D. Just-In-Time Access
🟢 C. Assume Breach
🔴 Explanation: The "Assume Breach" pillar focuses on minimizing the blast radius of an

managed devices. Which Microsoft tool should be used to enforce this?
A. Azure Bastion
B. Microsoft Sentinel
C. Conditional Access
D. Microsoft Priva
🟢 C. Conditional Access
