A security engineer needs to deploy a Palo Alto Networks firewall in a high-availability (HA) pair with active/passive mode. The firewall will inspect traffic for multiple tenants, each requiring separate routing and policy configuration. Which feature should be used to isolate tenant configurations while using a single pair of firewalls?
Virtual systems (VSYS) allow a single Palo Alto Networks firewall to be partitioned into multiple independent logical firewalls, each with its own routing table, security policies, and administrative domains. This enables tenant isolation on a single HA pair without requiring sep…Read full explanation
A firewall administrator notices that traffic from a specific subnet is being unexpectedly dropped. The firewall log shows a 'flow_drop' reason of 'packet too long for interface MTU'. The interface MTU is set to 1500, and the packets are 1500 bytes. What is the most likely cause?
When a packet is encapsulated (e.g., by IPsec) after the routing decision, the original packet's size remains 1500 bytes, but the encapsulation adds overhead (e.g., IPsec ESP headers/trailers, typically 50–60 bytes). This causes the resulting frame to exceed the interface MTU of …Read full explanation
An organization wants to simplify firewall rule management by grouping related rules into logical units and applying them to specific sets of users or devices. Which Palo Alto Networks feature supports this requirement?
Security policy rule groups allow administrators to organize related firewall rules into logical units, which can then be applied to specific users or devices via policy-based forwarding or rule placement. This feature simplifies management by grouping rules that share a common p…Read full explanation
