Cybersecurity-Practitioner Cybersecurity Fundamentals Practice Question
An enterprise security architect is designing a Zero Trust architecture using Palo Alto Networks products. Which THREE foundational principles must be enforced to achieve a true Zero Trust network posture? (Choose three)
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 by minimizing blast radius and segmenting networks, and inspecting all traffic
Zero Trust principles include verifying explicitly, using least privilege access, and assuming breach while inspecting all traffic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Assume breach by minimizing blast radius and segmenting networks, and inspecting all traffic
Why this is correct
Correct. Assuming breach requires continuous monitoring, micro-segmentation, and end-to-end encryption/inspection.
- ✓
Verify explicitly by authenticating and authorizing based on all available data points (identity, location, device health)
Why this is correct
Correct. Explicit verification is a core pillar of Zero Trust.
- ✓
Use least privilege access by restricting user and device access with risk-based adaptive policies
Why this is correct
Correct. Least privilege access limits user and device privileges to the bare minimum required.
- ✗
Trust the internal network perimeter implicitly once a user successfully authenticates via VPN
Why it's wrong here
Incorrect. Zero Trust explicitly rejects implicit trust based on network location or initial VPN authentication.
- ✗
Bypass security inspection for internal-to-internal data center traffic to maximize network performance
Why it's wrong here
Incorrect. Zero Trust mandates inspecting all traffic, including internal lateral movement.
