Palo Alto PCNSE Practice Exam Questions


Question # 1

A firewall engineer has determined that, in an application developed by the company's internal team, sessions often remain idle for hours before the client and server exchange any data. The application is also currently identified as unknown-tcp by the firewalls. It is determined that because of a high level of trust, the application does not require to be scanned for threats, but it needs to be properly identified in Traffic logs for reporting purposes. Which solution will take the least time to implement and will ensure the App-ID engine is used to identify the application?
A. Create a custom application with specific timeouts and signatures based on patterns discovered in packet captures.
B. Access the Palo Alto Networks website and raise a support request through the Customer Support Portal.
C. Create a custom application with specific timeouts, then create an application override rule and reference the custom application.
D. Access the Palo Alto Networks website and complete the online form to request that a new application be added to App-ID.


C. Create a custom application with specific timeouts, then create an application override rule and reference the custom application.
Explanation: For an application that is currently identified as unknown-tcp and has sessions that often remain idle for long periods, creating a custom application and using an application override rule is the most time-efficient solution.
C. The process involves:
Creating a custom application in the Palo Alto Networks firewall and configuring it with specific timeouts to accommodate the application's idle session behavior. This step ensures that the firewall does not prematurely close the application's sessions due to inactivity.
Next, creating an application override rule that references the custom application. This rule directs the firewall to identify traffic matching the rule criteria (such as source, destination, and port information) as the custom application, bypassing the App-ID engine's regular identification process.
This approach allows for the quick implementation of a solution that ensures the application is properly identified in traffic logs without undergoing threat scanning, meeting the requirements for both identification and reporting.



Question # 2

A firewall engineer needs to update a company's Panorama-managed firewalls to the latest version of PAN-OS. Strict security requirements are blocking internet access to Panorama and to the firewalls. The PAN-OS images have previously been downloaded to a secure host on the network. Which path should the engineer follow to deploy the PAN-OS images to the firewalls?
A. Upload the image to Panorama > Software menu, and deploy it to the firewalls. *
B. Upload the image to Panorama > Device Deployment > Dynamic Updates menu, and deploy it to the firewalls.
C. Upload the image to Panorama > Dynamic Updates menu, and deploy it to the firewalls.
D. Upload the image to Panorama > Device Deployment > Software menu, and deploy it to the firewalls.


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



Question # 3

Which two items must be configured when implementing application override and allowing traffic through the firewall? (Choose two.)
A. Application filter
B. Application override policy rule
C. Security policy rule
D. Custom app


B. Application override policy rule
C. Security policy rule
Explanation: 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.



Question # 4

A network engineer troubleshoots a VPN Phase 2 mismatch and decides that PFS (Perfect Forward Secrecy) needs to be enabled. What action should the engineer take?
A. Enable PFS under the IKE gateway advanced options.
B. Enable PFS under the IPSec Tunnel advanced options.
C. Add an authentication algorithm in the IPSec Crypto profile.
D. Select the appropriate DH Group under the IPSec Crypto profile.


B. Enable PFS under the IPSec Tunnel advanced options.



Question # 5

An administrator configures a preemptive active-passive high availability (HA) pair of firewalls and configures the HA election settings on firewall-02 with a device priority value of 100, and firewall-01 with a device priority value of 90. When firewall-01 is rebooted, is there any action taken by the firewalls?
A. No - Neither firewall takes any action because firewall-01 cannot be rebooted when configured with device priority of 90.
B. No - Neither firewall takes any action because firewall-02 is already the active-primary member.
C. Yes - Firewall-02 takes over as the active-primary firewall; firewall-01 takes over as the active-primary member after it becomes functional.
D. Yes - Firewall-02 takes over as the active-primary firewall; firewall-02 remains the active-primary member after firewall-01 becomes functional.


C. Yes - Firewall-02 takes over as the active-primary firewall; firewall-01 takes over as the active-primary member after it becomes functional.



Question # 6

Which three multi-factor authentication methods can be used to authenticate access to the firewall? (Choose three.)
A. Voice
B. Fingerprint
C. SMS
D. User certificate
E. One-time password


C. SMS
D. User certificate
E. One-time password
Explanation: The firewall can use three multi-factor authentication methods to authenticate access to the firewall: SMS, user certificate, and one-time password. These methods can be used in combination with other authentication factors, such as username and password, to provide stronger security for accessing the firewall web interface or CLI. The firewall can integrate with various MFA vendors that support these methods through RADIUS or SAML protocols5. Voice and fingerprint are not supported by the firewall as MFA methods.

Question # 7

Which two scripting file types require direct upload to the Advanced WildFire portal/API for analysis? (Choose two.)
A. Ps1
B. Perl
C. Python
D. VBS


B. Perl
D. VBS
