NEW QUESTION # 36
A security administrator wants to determine which action a URL Filtering profile will take on the URL "www.chatgpt.com." The firewall has a custom URL object with "www.chatgpt.com/" as a member called "Permitted-AI." The URL "www.chatgpt.com" is also categorized as "Artificial- Intelligence, " "Computer-and-Internet-Info," and "Low-Risk." The URL Filtering profile has the following in descending order:
- Artificial-Intelligence set to continue
- Computer-and-Internet-Info set to block
- Low-Risk set to alert
- Permitted-AI set to allow
Which action will the URL Filtering profile take when traffic matches the "www.chatgpt.com" URL on a rule with this profile attached?
- A. Allow
- B. Continue
- C. Block
- D. Alert
Answer: A
Explanation:
Custom URL categories take precedence over predefined URL category matches in the profile evaluation. Since the URL is explicitly included in the custom object mapped to an allow action, that rule is applied before the standard category actions, resulting in the traffic being permitted.
NEW QUESTION # 37
In which two Security Profiles can an action equal to the block IP feature be configured? (Choose two.)
- A. Antivirus b
- B. Vulnerability Protection
- C. URL Filtering
- D. Anti-spyware
Answer: B,D
Explanation:
The block IP feature can be configured in two Security Profiles: Vulnerability Protection and Anti-spyware.
The block IP feature allows the firewall to block traffic from a source IP address for a specified period of time after detecting a threat. This feature can help prevent further attacks from the same source and reduce the load on the firewall1. The block IP feature can be enabled in the following Security Profiles:
Vulnerability Protection: A Vulnerability Protection profile defines the actions that the firewall takes to protect against exploits and vulnerabilities in applications and protocols. You can configure a rule in the Vulnerability Protection profile to block IP connections for a specific threat or a group of threats2.
Anti-spyware: An Anti-spyware profile defines the actions that the firewall takes to protect against spyware and command-and-control (C2) traffic. You can configure a rule in the Anti-spyware profile to block IP addresses for a specific spyware or C2 signature.

Which log type should be checked first using Log Viewer when a user reports being unable to access a specific website?
- A. Firewall/Threat
- B. Firewall/Traffic
- C. Firewall/URL
- D. Firewall/DNS Security
Answer: B
Explanation:
Traffic logs show whether the session was allowed or denied and which security policy handled the connection. Checking these logs first confirms if the firewall is blocking the session or if the issue lies elsewhere before reviewing more specific logs like URL or threat events.

NEW QUESTION # 44
A newly acquired subsidiary operates its own legacy firewall system, separate from the parent company's Palo Alto Networks infrastructure. The parent company's security mandate is to onboard the subsidiary into the central Panorama management and apply standardized security profiles. Before migration, the security team needs to understand the subsidiary's current traffic patterns, identify all applications in use, and discover any potential vulnerabilities or misconfigurations. Post-migration, they need to validate that the new policies are correctly enforced and that no critical services are disrupted. How would a Network Security Analyst use the integrated capabilities of Command Center, Activity Insights, and Policy Optimizer throughout this migration lifecycle?
- A. Pre-migration: Manually review the subsidiary's legacy firewall logs. Post-migration: Use Command Center to monitor for any 'deny' logs from the new Palo Alto Networks firewall.
- B. Pre-migration: Use Policy Optimizer to simulate policy changes on the legacy firewall logs. Post-migration: Use Activity Insights to generate compliance reports for the new policies.
- C. Pre-migration: Run vulnerability scans against the subsidiary's network. Post-migration: Rely on Policy Optimizer's recommendations to improve the security posture.
- D. Pre-migration: Interview the subsidiary's IT staff to document applications and services. Post-migration: Conduct penetration tests to validate policy enforcement.
- E. Pre-migration: Deploy a temporary Palo Alto Networks firewall in 'tap mode' or integrate logs into a SIEM that can feed Activity Insights. Analyze Activity Insights for application usage and user behavior. Post-migration: Use Command Center for real-time monitoring of policy hits and traffic flow, and Policy Optimizer to identify any 'unused' rules from the new consolidated policy set.
Answer: E
Explanation:
This scenario emphasizes data-driven decision making throughout a migration. Pre-migration: Deploying a Palo Alto Networks firewall in 'tap mode' (passive monitoring) or feeding logs into a system that can ingest them into Activity Insights (e.g., via a logging service or SIEM integration) is crucial. This allows Activity Insights to learn the subsidiary's actual traffic patterns, applications, and user behavior before any policy changes are made. This data is invaluable for accurately translating legacy policies to Palo Alto Networks policies and avoiding service disruption. Post-migration: Once the new policies are deployed, Command Center provides real-time visibility to immediately identify any traffic being unexpectedly dropped or routed, allowing for quick troubleshooting and validation of the new policies. Policy Optimizer can then be used to refine the newly implemented policies, identifying any rules that might have been carried over but are now 'unused' or overly broad in the new consolidated environment, thereby continuously improving the security posture.
NEW QUESTION # 45
After making multiple changes to the candidate configuration of a firewall, the administrator would like to start over with a candidate configuration that matches the running configuration.
Which command in Device > Setup > Operations would provide the most operationally efficient way to accomplish this?
- A. Revert to last saved configuration
- B. Load named configuration snapshot
- C. Import named config snapshot
- D. Revert to running configuration
Answer: D
NEW QUESTION # 46
A company is deploying a new Palo Alto Networks firewall and requires comprehensive visibility into encrypted traffic. They plan to implement SSL Forward Proxy decryption. During testing, users report issues accessing various websites, including some financial institutions and healthcare portals. Upon investigation, the firewall logs show 'Untrusted Certificate' errors. Which of the following is the most likely cause and the immediate corrective action?
- A. The firewall's root CA certificate used for signing intercepted traffic has not been distributed to client trust stores.
- B. The decryption policy rule is set to 'No Decryption' for these specific URL categories.
- C. The 'SSL Inbound Inspection' profile is misconfigured.
- D. The firewall's clock is out of sync with NTP, leading to certificate validity issues.
- E. The 'Block Sessions with Unknown Status' setting is enabled in the SSL Protocol Settings of the decryption profile.
Answer: A
Explanation:
When SSL Forward Proxy decryption is enabled, the firewall acts as a man-in-the-middle, generating new certificates for intercepted connections, signed by its own Root CA. If this Root CA is not trusted by the client devices (i.e., not distributed to their trust stores), clients will receive an 'Untrusted Certificate' error. This is a very common initial hurdle in forward proxy deployments. Options B and D are unlikely to cause 'Untrusted Certificate' errors. Option C might cause blocks, but the primary error message points to trust. Option E is a possibility for certificate validity, but 'Untrusted Certificate' directly implies a missing trust anchor for the firewall's self-signed certificates.
NEW QUESTION # 47
An administrator wants to enable access to www.paloaltonetworks.com while denying access to all other sites in the same category.
Which object should the administrator create to use as a match condition for the security policy rule that allows access to www.paloaltonetworks.com?
- A. URL category
- B. Application group
- C. Service
- D. Address ab
Answer: A
Explanation:
A URL category object is the object that the administrator should create to use as a match condition for the security policy rule that allows access to www.paloaltonetworks.com while denying access to all other sites in the same category. A URL category object allows the administrator to define a custom list of URLs that belong to a specific category, such as Business and Economy. The administrator can then use this object in a security policy rule to allow or deny access to the URLs based on the category1. For example, the administrator can create a URL category object that contains www.paloaltonetworks.com and assign it to the Business and Economy category. Then, the administrator can create a security policy rule that allows access to this URL category object and denies access to the predefined Business and Economy category2. References: Create a Custom URL Category, Create a Security Policy Rule to Allow or Deny Access to a Custom URL Category, Certifications - Palo Alto Networks, Palo Alto Networks Certified Network Security Administrator (PAN-OS 10.0) or [Palo Alto Networks Certified Network Security Administrator (PAN-OS 10.0)].
NEW QUESTION # 48
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, 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'.
- B. 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.
- C. 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.
- 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), Next Hop: 192.0.2.254. This requires an inter-vSys forwarding mechanism to be configured.
- E. 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.
Answer: A
Explanation:
This is a complex inter-vSys PBF scenario. Palo Alto Networks firewalls can forward traffic between Virtual Systems using a special configuration called an 'Inter-vSys Link'. This is a logical link, not a physical one, that allows traffic from one vSys to be forwarded to another. Inter-vSys Link (Critical Element): An 'Inter-vSys Link' must be configured under 'Network > Virtual Wires' or 'Network > Interfaces' (depending on the PAN-OS version and desired setup). This link creates a logical connection between two Virtual Routers across different vSystems. One end is attached to a Virtual Router in 'vSys_A', and the other to a Virtual Router in 'vSys_B'. PBF Rule: In 'vSys_A', the PBF rule will then specify the 'Egress Interface' as the 'Inter-vSys Link Interface' that connects to 'vSys_B'. The 'Next Hop' would be the IP address of the proxy (192.0.2.254), which is assumed to be reachable via 'vSys_B'. Let's evaluate other options: Option A: A PBF rule in 'vSys_A' cannot directly specify an egress interface that belongs to 'vSys_B'. They are isolated routing domains. Option B and D: The 'Virtual Router' action in PBF is for transferring traffic between Virtual Routers within the same Virtual System . It cannot transfer traffic between different Virtual Systems directly. Option E: This is incorrect. While dedicated physical links can be used, the 'Inter-vSys Link' feature is designed for logical forwarding between vSystems without consuming additional physical interfaces for simple transfers like this.
