The best way for the administrator to meet the requirement of managing all configuration from Panorama and preventing local overrides is B: Perform a template commit push from Panorama using the “Force Template Values” option. This option allows the administrator to overwrite any local configuration on the firewall with the values defined in the template1. This way, the administrator can ensure that the interface configuration and any other

When implementing an application override in a Palo Alto Networks firewall, the primary goal is to explicitly define how specific traffic is identified and processed by the firewall, bypassing the regular App-ID process. This is particularly useful for traffic that might be misidentified by App-ID or for applications that require special handling for performance reasons.

To successfully implement application override, the following items must be configured:

B. Application override policy rule:

This is a specialized policy rule that you create to specify the criteria for the traffic you want to override. In this rule, you define the source and destination zones, addresses, and ports. Instead of relying on the App-ID engine to identify the application, the firewall uses the criteria defined in the application override policy to classify the traffic.

C. Security policy rule:

After defining an application override policy, you must also configure a security policy rule to allow the overridden traffic through the firewall. This rule specifies the action (allow, deny, drop, etc.) for the traffic that matches the application override policy. It's essential to ensure that the security policy rule matches the traffic defined in the application override policy to ensure that the intended traffic is allowed through the firewall.

For detailed guidance on configuring application override and the necessary security policies, refer to the official Palo Alto Networks documentation. This resource provides step-by-step instructions and best practices for effectively managing traffic using application overrides.

When using certificate authentication for firewall administration on Palo Alto Networks devices, the method used for authorization is typically the Local database. Certificate authentication ensures that the entity attempting to access the firewall is in possession of a valid certificate. Once the certificate is validated for authentication, the authorization process determines what level of access or permissions the authenticated entity has. This is usually managed locally on the firewall, where administrators can define roles and permissions associated with different users or certificates. Thus, the authorization process, in this case, leverages the Local database to enforce access controls and permissions, aligning with best practices for secure management of network devices.

In a situation where Panorama and its managed firewalls lack internet access, updating PAN-OS requires a manual upload of the downloaded PAN-OS images. The process involves:

D. Upload the image to Panorama > Device Deployment > Software menu, and deploy it to the firewalls:

The engineer first uploads the downloaded PAN-OS images to Panorama. This is done through the "Device Deployment" section, specifically under the "Software" menu. This area of Panorama's interface is designed for managing PAN-OS versions and software updates for the managed devices.

Once the PAN-OS images are uploaded to Panorama, the engineer can then deploy these images to the firewalls directly from Panorama. This process allows for centralized management of software updates, ensuring that all firewalls can be updated to the latest PAN-OS version in a consistent and controlled manner, even without direct internet access.

This method streamlines the update process for environments with strict security requirements, allowing for the efficient deployment of necessary PAN-OS updates to maintain security and functionality.

WildFire logs showing a "malicious" verdict with an "allow" action indicate that the initial traffic wasn’t blocked in real-time, likely because the Antivirus profile isn’t configured to act immediately on WildFire verdicts. By default, WildFire submits files for analysis, and signatures may take up to 24 hours to propagate globally unless real-time blocking is enabled. Configuring the Antivirus security profile (Option B) to "block" on malicious WildFire verdicts ensures that threats are blocked within minutes once the verdict is returned (typically 5-15 minutes), leveraging WildFire’s real-time signature updates.

Option A (WildFire analysis profile) defines what files are sent to WildFire but doesn’t control blocking actions. Option C (File Blocking profile) manages file type blocking, not threat verdicts. Option D (file size limits) affects submission eligibility, not blocking behavior. The Antivirus profile is the key to real-time WildFire enforcement, as per Palo Alto Networks documentation.

To override a device and network setting applied by a template, you can either configure the setting locally on the firewall or override the setting on the template stack. Configuring the setting locally on the firewall will copy the setting to the local configuration of the device and will no longer be controlled by the template. Overriding the setting on the template stack will apply the setting to all the firewalls that are assigned to the template stack, unless the setting is also overridden locally on a firewall. Changing the setting on the global template will affect all the firewalls that inherit the setting from the template, which is not desirable in this scenario. Configuring a service route for DNS on a different interface will not change the DNS server address, but only the interface that the firewall uses to reach the DNS server. References:

The type of policy in Palo Alto Networks firewalls that can use Device-ID as a match condition is QoS. This is because Device-ID is a feature that allows the firewall to identify and classify devices on the network based on their characteristics, such as vendor, model, OS, and role1. QoS policies are used to allocate bandwidth and prioritize traffic based on various criteria, such as application, user, source, destination, and device2. By using Device-ID as a match condition in QoS policies, the firewall can apply different QoS actions to different types of devices, such as IoT devices, laptops, smartphones, etc3. This can help optimize the network performance and ensure the quality of service for critical applications and devices.

D is the correct answer because the threat log type would provide information about traffic blocked by a Zone Protection profile. This is because Zone Protection profiles are used to protect the network from attacks, including common flood, reconnaissance attacks, and other packet-based attacks1. These attacks are classified as threats by the firewall and are logged in the threat log2. The threat log displays information such as the source and destination IP addresses, ports, zones, applications, threat types, actions, and severity of the threats2.

To prevent the import from affecting ongoing traffic when you import the configuration of an HA pair into Panorama, you should disable config sync on both firewalls. Config sync is a feature that enables the firewalls in an HA pair to synchronize their configurations and maintain consistency. However, when you import the configuration of an HA pair into Panorama, you want to avoid any changes to the firewall configuration until you verify and commit the imported configuration on Panorama. Therefore, you should disable config sync before importing the configuration, and re-enable it after committing the changes on Panorama12. References: Migrate a Firewall HA Pair to Panorama Management, PCNSE Study Guide (page 50)

Wireshark (Option C) is a packet capture tool that provides detailed application traffic patterns (e.g., ports, protocols, payloads), essential for defining custom application signatures in PAN-OS.

Option A (Policy Optimizer) analyzes existing rules, not raw traffic. Option B (Data Filtering Log) shows data patterns, not app behavior. Option D (Expedition) is for migration, not signature creation. Documentation recommends packet captures for this task.
