CAS-004 Migrating to a zero trust architecture Practice Question
A company is migrating to a zero trust architecture. Which of the following is a key principle of zero trust?
⚠ Common exam trap
Candidates often confuse 'trust but verify' (Option D) with zero trust, but zero trust explicitly eliminates the initial trust assumption, requiring verification before any access is granted, not after.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Assume breach and verify every request
Zero trust architecture is built on the principle of 'never trust, always verify,' which explicitly requires that every access request—regardless of origin—be authenticated, authorized, and continuously validated. Option B ('Assume breach and verify every request') captures this core tenet, as it mandates that no implicit trust is granted based on network location or device status, and every request must be treated as potentially malicious until proven otherwise.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Allow all traffic within the corporate network
Why it's wrong here
Zero trust requires micro-segmentation and strict access controls.
- ✓
Assume breach and verify every request
Why this is correct
Zero trust operates on the principle of never trusting and always verifying.
- ✗
Trust devices based on their IP address
Why it's wrong here
Zero trust does not trust based on IP; it requires continuous verification.
- ✗
Trust but verify for all internal traffic
Why it's wrong here
Zero trust is 'never trust, always verify', not 'trust but verify'.
