NetSec-Architect Zero Trust Architecture And Design Practice Question
An architect is designing a Zero Trust network segmentation strategy for an enterprise data center using Palo Alto Networks firewalls. Which TWO architectural principles are fundamental to this design? (Choose two)
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 explicitly for every transaction, regardless of network origin
Zero Trust mandates assuming breach and verifying explicitly, as well as enforcing least-privilege access across all segments.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Rely exclusively on perimeter gateway firewalls while leaving internal networks unmonitored
Why it's wrong here
Incorrect. Perimeter-only security contradicts Zero Trust.
- ✗
Disable user identification and threat inspection for internal database clusters
Why it's wrong here
Incorrect. Internal databases require rigorous inspection and identity context.
- ✓
Assume breach and verify explicitly for every transaction, regardless of network origin
Why this is correct
Correct. Assuming breach and verifying explicitly are core tenets of Zero Trust.
- ✗
Establish wide-open internal trust zones to maximize east-west application performance
Why it's wrong here
Incorrect. Zero Trust eliminates implicit internal trust zones.
- ✓
Enforce strict least-privilege access control based on user, device, and application context
Why this is correct
Correct. Least-privilege access based on granular context is fundamental to ZT.
