Palo Alto Networks Certified Network Security Administrator (PCNSA)Palo Alto Networks Security PlatformHard
A network security architect is designing a multi-tenant environment using a single Palo Alto Networks firewall. Each tenant requires complete isolation of their network traffic and dedicated security policies, while sharing the physical hardware. Which firewall feature allows for this logical segmentation and independent management within a single physical device?
- AVirtual Systems (vSys)
- BVirtual Routers
- CSecurity Zones
- DService Routes
Show answer & explanationAnswer & explanation
Correct answer: A. Virtual Systems (vSys)
Virtual Systems (vSys) allow a single physical Palo Alto Networks firewall to be logically partitioned into multiple independent virtual firewalls. Each vSys has its own virtual interfaces, security zones, routing tables, and security policies, providing complete separation and independent management for multi-tenant environments.
Why the other options are wrong
- B. Virtual Routers handle routing within a single logical firewall context, not independent firewall instances for multi-tenancy.
- C. Security Zones group interfaces for policy enforcement but do not provide complete logical separation and independent management for multiple tenants.
- D. Service Routes define paths for management traffic, not for tenant isolation or logical firewall partitioning.
Virtual Systems (vSys)
A feature on Palo Alto Networks firewalls that allows a single physical device to be partitioned into multiple logical, independent firewall instances, each with its own interfaces, zones, policies, and management, suitable for multi-tenant environments.
- Logical partitioning of a single firewall
- Independent interfaces, zones, policies, routing
- Ideal for multi-tenant or departmental separation
- Requires specific licensing
Memory trick: Virtual Systems divide with might, giving each tenant their own security light.
