Question 1

A PAN-OS administrator needs to ensure that a specific critical server in the DMZ is always reachable via the same public IP, regardless of which interface handles the traffic. Which NAT type achieves this?

Accepted Answer

Static NAT with bidirectional enabled

Answer

Static NAT with bidirectional enabled creates a permanent one-to-one mapping between a private IP and a public IP, allowing both inbound and outbound traffic translation.

Question 2

Which PAN-OS operational mode allows an administrator to test configuration changes in a sandboxed environment before committing them to the running configuration?

Accepted Answer

Candidate configuration

Answer

The candidate configuration in PAN-OS stores uncommitted changes that can be tested and reviewed before being committed to the active running configuration.

Question 3

When WildFire analysis identifies a previously unknown file as malware, how does PAN-OS distribute the new threat signature to subscribed firewalls?

Accepted Answer

Automatically through WildFire signature updates, delivered within minutes of verdict generation

Answer

WildFire delivers new malware signatures to subscribed firewalls within approximately 5 minutes of verdict generation through automated signature updates.

Question 4

An administrator is troubleshooting why traffic matching a security policy rule is being dropped. The 'test security-policy-match' CLI command shows the correct rule, but traffic still fails. What should be checked next?

Accepted Answer

Verify the security profile applied to the rule is not blocking the traffic

Answer

Even when a security rule allows traffic, an attached Security Profile (e.g., Vulnerability Protection, Antivirus) may detect and block the traffic based on threat content.

Question 5

Which Panorama feature allows an administrator to push a consistent set of interface, routing, and zone configurations to multiple managed firewalls using a template-based approach?

Accepted Answer

Templates and Template Stacks

Answer

Panorama Templates define network-level settings (interfaces, routing, zones), and Template Stacks allow layering templates for hierarchical configuration push to managed firewalls.
