An enterprise network security team is deploying VM-Series firewalls in a multi-cloud environment. Some firewalls are deployed in VMware NSX-V, while others are in AWS, and all are centrally managed using Panorama with the appropriate plugins installed. The team wants to streamline policy management by organizing the firewalls into device groups in which the AWS-based firewalls act as a parent device group, while the NSX-V firewalls are configured as a child device group to inherit Security policies. However, after configuring the device group hierarchy and attempting to push configurations, the team receives errors, and policy inheritance is not functioning as expected. What is the most likely cause of this issue?
Correct Answer: D
Panorama's device group hierarchy supports policy inheritance, but it does not support inheritance across groups with firewalls on different hypervisors (e.g., AWS and NSX-V) when managed by multiple plugins (Option D). AWS and NSX-V firewalls use distinct plugins (e.g., AWS Plugin, NSX Plugin), and Panorama restricts cross-hypervisor inheritance due to differing configurations and contexts, causing errors when pushing policies. Option A (plugin versions) is unrelated to inheritance. Option B (object overrides) isn't a requirement for this issue. Option C (command) is fictional. Documentation confirms this limitation.

PCNSE Exam Question 104
Which tool will allow review of the policy creation logic to verify that unwanted traffic is not allowed?
Correct Answer: B
The Test Policy Match tool in PAN-OS allows administrators to simulate traffic against the current security policy set to verify how it will be handled. By inputting source/destination IPs, ports, protocols, and other parameters, it shows which rule matches and whether the traffic is allowed or denied, making it ideal for ensuring unwanted traffic is blocked. Option A (Managed Devices Health) monitors device status, not policy logic. Option C (Preview Changes) shows configuration diffs, not traffic matching. Option D (Policy Optimizer) helps refine rules but doesn't test specific traffic scenarios. Test Policy Match is the documented tool for this purpose. Reference: PAN-OS 11.2 Administrator's Guide, "Policies" section - Test Policy Match Tool.
PCNSE Exam Question 105
What happens when an A/P firewall pair synchronizes IPsec tunnel security associations (SAs)?
Correct Answer: B
In a High Availability (HA) setup with Palo Alto Networks firewalls, the synchronization of IPsec tunnel Security Associations (SAs) is an important aspect to ensure seamless failover and continued secure communication. Specifically, for Phase 2 SAs, they are synchronized over the HA2 links. The HA2 link is dedicated to synchronizing sessions, forwarding tables, IPSec SA, ARP tables, and other critical information between the active and passive firewalls in an HA pair. This ensures that the passive unit can immediately take over in case the active unit fails, without the need for re-establishing IPsec tunnels, thereby maintaining secure communications without interruption. It's important to note that Phase 1 SAs, which are responsible for establishing the secure tunnel itself, are not synchronized between the HA pair, as these need to be re-established upon failover to ensure secure key exchange.
