A cybersecurity firm manages multiple tenants on a single Palo Alto Networks firewall using Virtual Systems (vSys). Each vSys has its own PBF policies. A new requirement dictates that all outbound web traffic (TCP/80, 443) from a specific subnet (172.16.0.0/24) in 'vSys_A' must first be directed to an external web proxy (192.0.2.254) before being sent to the internet. This proxy is located in a different vSys, 'vSys_B', which has a dedicated interface (ethernet1/10) for this proxy integration. All other traffic from 172.16.0.0/24 in 'vSys A' should follow its regular internet path. Which PBF configuration is appropriate, and what critical inter-vSys element is needed?

• A.In 'vSys_A', create a PBF rule: Source Address: 172.16.0.0/24, Application: web-browsing, ssl, Action: Forward, Virtual Router: (Virtual Router in vSys_B), Next Hop: 192.0.2.254. This requires an inter-vSys forwarding mechanism to be configured.
• B.In 'vSys_A', create a PBF rule: Source Address: 172.16.0.0/24, Application: web-browsing, ssl, Action: Forward, Egress Interface: (Inter-vSys Link Interface), Next Hop: 192.0.2.254. An 'Inter-vSys Link' must be configured between 'vSys_A' and 'vSys_B'.
• C.This scenario requires a dedicated physical interface to connect 'vSys_A' to 'vSys_B' as an 'inter-vSys' data plane link, and PBF cannot be used to directly forward traffic between Virtual Systems.
• D.In 'vSys_A', create a PBF rule: Source Address: 172.16.0.0/24, Application: web-browsing, ssl, Action: Forward, Virtual Router: (Virtual Router in vSys_B where the proxy's network resides). In 'vSys_B', a static route for 172.16.0.0/24 must point to the proxy via ethernet1/10.
• E.In 'vSys_A', create a PBF rule: Source Address: 172.16.0.0/24, Application: web-browsing, ssl, Egress Interface: ethernet1/10 (assigned to vSys_B), Next Hop: 192.0.2.254, Action: Forward. Ensure a security policy exists in vSys_B to allow traffic from vSys_A to the proxy.

A Palo Alto Networks Network Security Engineer is developing an automated remediation script to respond to specific, repeatable 'DLP Violation' incidents. The script needs to retrieve the 'source-user' and 'destination-IP' from the incident, dynamically create a new security policy rule to block the 'source-user' from accessing the 'destination-IP', and then commit the changes. Assuming the script can query the Incidents and Alerts page API (using XSOAR or custom code) for active incidents and interact with the firewall via its XML API/REST API, what is the MOST critical data point to extract from the incident, and which API operation would be necessary for creating the blocking rule?

• A.Critical Data Point: 'user' (from incident context) and 'destination' (from incident context). API Operation:
  
• B.Critical Data Point: 'threat-id'. API Operation:
  
• C.Critical Data Point: 'source-user' and 'destination-ipt (as directly available fields from the incident object). API Operation:
  
• D.Critical Data Point: 'src' (from log data within incident) and 'dst' (from log data within incident). API Operation:
  
• E.Critical Data Point: 'incident-id' and 'log-entry-count'. API Operation:
  

A large e-commerce platform uses an internal REST API service on TCP/443 for microservices communication. While it uses TLS, App-ID often misidentifies it as 'web-browsing' or 'ssl', preventing granular policy enforcement based on the actual API application. The security team wants to classify this traffic as 'internal-rest-api' (a custom application) and apply a custom URL Filtering profile that blocks only specific API endpoints, not general web browsing. They also need to ensure that this override does not affect legitimate 'web- browsing' traffic to external sites over TCP/443. Which configuration strategy should be employed?

• A.Create an Application Override policy for TCP/443 to 'internal-rest-api' from the internal microservices zone to the API gateway zone. Then, create a security policy allowing 'internal-rest-api' with the custom URL Filtering profile. Ensure the Application Override rule is placed before any general web-browsing rules.
• B.Create an Application Override policy for TCP/443 to 'internal-rest-api' from the internal microservices zone to the API gateway zone. Then, create a security policy allowing 'internal-rest-api' with the custom URL Filtering profile. Ensure the Application Override rule is placed after any general web-browsing rules.
• C.Configure SSL Decryption for the internal REST API traffic, and then use the decrypted traffic to apply more precise App-ID and URL filtering.
• D.Create a custom application signature that identifies the specific HTTP Host header for the internal REST API service. Then, create a security policy allowing this custom application with the desired URL Filtering profile.
• E.Modify the 'SSI' application definition to exclude the internal REST API server's IP address. Then, create a separate security policy for the internal REST API allowing 'any' application on TCP/443 with the custom URL Filtering profile.

Consider the following firewall policy configuration snippet from a Panorama managed firewall:

An analyst observes internal users are still able to browse external HTTP websites, contradicting the 'Block-External-Browsing' rule. Using Policy Optimizer, Command Center, and Activity Insights, what is the most likely reason for this behavior, and how would these tools help identify and rectify it? (Select all that apply)

• A.Most Likely Reason: The 'service' in 'Block-External-Browsing' is 'any', making it less specific than 'Allow-Internal-HTTP' and thus being hit first for internal traffic. Tool Action: Policy Optimizer would recommend making the 'Block-External-Browsing' rule more specific, possibly by adding a source or destination zone.
• B.Most Likely Reason: The 'Block-External-Browsing' rule is placed lower in the rulebase than 'Allow-Internal-HTTP'. Tool Action: Policy Optimizer's 'Rule Order' view would visually indicate the incorrect placement. Command Center session logs would confirm traffic hitting 'Allow-Internal-HTTP' instead of 'Block-External-Browsing'.
• C.Most Likely Reason: Users are bypassing the firewall using a VPN. Tool Action: Activity Insights would show a drop in 'web-browsing' activity but an increase in VPN application usage. Command Center would show VPN tunnel traffic bypassing policy checks.
• D.Most Likely Reason: The 'Allow-Internal-HTTP' rule is shadowing 'Block-External-Browsing'. Tool Action: Policy Optimizer would highlight 'Allow-Internal-HTTP' as a shadowed rule or show its 'usage' affecting external traffic. Command Center would show sessions hitting 'Allow-Internal-HTTP' for external destinations.
• E.Most Likely Reason: The firewall is not configured to perform App-ID on HTTP traffic. Tool Action: Activity Insights would show traffic categorized as 'unknown- tcp' instead of 'web-browsing' for HTTP. Command Center would display sessions with 'unknown-tcp' as the application.

Consider a large-scale network migration where an organization is transitioning thousands of physical Palo Alto Networks firewalls to a mix of physical and virtual firewalls, all to be managed by Strata Cloud Manager (SCM). The migration plan involves frequent, scheduled policy updates across different device groups. How can an administrator programmatically automate the policy update process and verify successful deployment for multiple device groups using SCM's API?

• A.Manually SSH into each firewall and apply policy updates sequentially, then check logs locally.
• B.Utilize the SCM GUI for batch operations, as API is not suitable for large-scale migrations.
• C.Develop a Python script that leverages SCM's RESTful API endpoints for configuration management and retrieves job status for deployment validation.
• D.Implement an SNMP-based monitoring system to push configurations and receive alerts.
• E.Deploy a dedicated firewall management server (Panorama) instead of SCM for such a large migration.
