NetSec-Architect Zero Trust Architecture And Design Practice Question
When implementing a Zero Trust network segmentation strategy using Palo Alto Networks firewalls, which architectural placement is recommended for implementing internal segmentation gateways (ISGs)?
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
✓
At strategic chokepoints within the internal network architecture (east-west boundaries) to isolate sensitive assets and workloads
Internal Segmentation Gateways (ISGs) are deployed inside the data center or campus core to control traffic moving laterally (east-west) between different security zones, applications, or business units.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
At strategic chokepoints within the internal network architecture (east-west boundaries) to isolate sensitive assets and workloads
Why this is correct
Correct. ISGs are deployed internally to enforce least-privilege access between internal zones and application tiers.
- ✗
Directly on every end-user laptop as a software-only client package without any network gateway
Why it's wrong here
Incorrect. Endpoints use agents like GlobalProtect, not ISGs.
- ✗
Only inside public cloud VPCs as software gateways dedicated exclusively to VPN tunnels
Why it's wrong here
Incorrect. ISGs are used broadly for internal segmentation, including on-premises data centers and private clouds.
- ✗
Exclusively at the internet edge to inspect inbound and outbound traffic
Why it's wrong here
Incorrect. Internet edge firewalls protect against north-south traffic, not internal east-west segmentation.
