NetSec-Architect Zero Trust Architecture And Design Practice Question
An enterprise security architect is optimizing a complex Palo Alto Networks firewall policy structure to adhere to Zero Trust network segmentation principles. Which THREE strategies should be employed to properly restructure legacy 'perimetral' rules into micro-segmentation policies? (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
✓
Enabling comprehensive security profiles (Antivirus, Anti-Spyware, Vulnerability Protection, WildFire) on inter-zone traffic rules
Zero Trust policy restructuring involves replacing broad IP-based rules with Dynamic Address Groups, applying strict App-ID granularity instead of port-based services, and enforcing consistent threat profile inspection across all internal zones.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disabling all User-ID enforcement mechanisms to rely strictly on source MAC address binding
Why it's wrong here
MAC addresses can be easily spoofed and do not provide reliable user-level context for Zero Trust policies.
- ✓
Enabling comprehensive security profiles (Antivirus, Anti-Spyware, Vulnerability Protection, WildFire) on inter-zone traffic rules
Why this is correct
Zero Trust inspection requires full threat prevention profiles across all internal segmentation boundaries.
- ✓
Transitioning from broad L4 service objects (e.g., 'any' or 'tcp-high') to specific L7 App-IDs
Why this is correct
Least-privilege security mandates defining exact applications rather than allowing broad port ranges.
- ✗
Merging all internal IT and guest network zones into a single flat L2 virtual wire segment to simplify routing
Why it's wrong here
Merging zones creates a flat network, violating the core Zero Trust tenet of strict network segmentation.
- ✓
Replacing static IP address objects with Dynamic Address Groups (DAGs) populated via VM-Series or tag integrations
Why this is correct
DAGs allow automated, tag-based policy enforcement that adapts as workloads scale and move.
