Paloalto Networks Updated PCNSE Exam Questions and Answers by sasha

The AIOps Plugin for Panorama enhances security management by proactively validating commits against best practices (Option B). It analyzes policies, provides recommendations (e.g., unused rules, misconfigurations), and advises administrators before pushing changes, improving security posture without automatic enforcement.

Option A (auto-push) overstates its role; it advises, not pushes. Option C (auto-correct) is inaccurate; it suggests, not fixes. Option D (retroactive checks) misaligns with its proactive design. Documentation highlights its advisory function.

traffic log would list an application as “not-applicable” if the firewall denied the traffic before the application match could be performed. This can happen if the traffic matches a security rule that is set to deny based on any parameter other than the application, such as source, destination, port, service, etc1. In this case, the firewall does not inspect the application data and discards the traffic, resulting in a “not-applicable” entry in the application field of the traffic log1.

A and D are the best practice deployment modes for the firewall if the company wants to add threat prevention to the network without redesigning the network routing. This is because these modes allow the firewall to act as a transparent device that does not affect the existing network topology or routing1.

A: VirtualWire mode allows the firewall to be inserted into any existing network segment without changing the IP addressing or routing of that segment2. The firewall inspects traffic between two interfaces that are configured as a pair, called a virtual wire. The firewall applies security policies to the traffic and forwards it to the same interface from which it was received2.

D: Layer 2 mode allows the firewall to act as a switch that forwards traffic based on MAC addresses3. The firewall inspects traffic between interfaces that are configured as Layer 2 interfaces and belong to the same VLAN. The firewall applies security policies to the traffic and forwards it to the appropriate interface based on the MAC address table3.
