The Palo Alto Networks Certified Network Security Engineer (PCNSE) certification validates the skills required to design, deploy, configure, maintain, and troubleshoot Palo Alto Networks security platforms. It is designed for network security professionals who use Palo Alto Networks products. The certification confirms proficiency in configuring Palo Alto’s next-generation firewalls (NGFW), Panorama, GlobalProtect, and other features that protect against cyber threats. It demonstrates a deep understanding of firewall policies, security management, and network architectures to secure both on-premises and cloud-based networks.
The PCNSE exam is recommended for professionals with 3-5 years’ experience in network security. This is specifically for roles that involve working with Palo Alto Networks firewalls and platforms. Candidates should be familiar with network security concepts and have hands-on experience using Palo Alto solutions such as Palo Alto NGFW, Panorama, GlobalProtect, and WildFire. Practical experience with security policies, NAT, VPNs, and SSL decryption is vital, as well as knowledge of integration in both traditional and cloud environments. Experience troubleshooting and managing Palo Alto products in real-world scenarios is highly beneficial for exam preparation.
Understanding the architecture of Palo Alto Networks products is crucial for the PCNSE exam. Candidates must grasp how Palo Alto firewalls are structured, including the role of security zones, interfaces (Layer 2 & Layer 3), virtual systems, and high availability (HA) setups. The architecture determines how security policies are enforced across different network layers. It also determines how the firewall processes traffic, and how features like App-ID and User-ID interact within the security platform. Exam questions often focus on configuring and deploying firewalls in real-world scenarios, requiring candidates to design and manage the architecture effectively.
The PCNSE exam evaluates a range of management and operational skills, with a particular emphasis on:
Panorama Management: Manage multiple firewalls through a centralized interface, creating templates, and pushing configurations to managed devices.
Logging and Monitoring: Setting up log forwarding, log collection, creating custom reports, and monitoring traffic using the WebUI or CLI.
High Availability (HA): Configuring active/passive or active/active HA, session synchronization, and understanding failover mechanisms.
Device Management: Handling system maintenance tasks like upgrading the firewall’s operating system, creating backup configurations, and managing licenses.
Policy Management: Implementing and optimizing security policies and NAT rules and ensuring traffic flows correctly across interfaces and zones.
App-ID and Content-ID are critical features tested in the PCNSE exam. App-ID is a Palo Alto Networks technology that identifies applications traversing the network regardless of port, protocol, encryption (SSL), or evasive tactics. This technology allows granular traffic control based on application identity rather than just IP addresses or ports. This makes it a key differentiator for Palo Alto firewalls.
Content ID inspects and prevents content threats. It scans traffic for malware, vulnerabilities, and data filtering (such as blocking credit card numbers). Both technologies are central to firewall enforcement of security policy. Mastery of these concepts is necessary for configuring policies, understanding application behavior, and ensuring data security.
Firewall rules and policies are tested extensively in the PCNSE exam. Candidates must demonstrate proficiency in:
Security Policies: Writing rules that control traffic flow across different zones based on user identity, application, and content.
NAT Policies: Understanding Source NAT (SNAT), Destination NAT (DNAT), and their interaction with security rules.
Decryption Policies: Implementing SSL decryption to inspect encrypted traffic while maintaining secure connections.
QoS Policies: Configuring Quality of Service (QoS) rules to prioritize certain types of traffic.
Policy Management: Candidates are tested on the sequence and logic of policies, troubleshooting misconfigurations, and optimizing the firewall rule base to minimize performance overhead.
WildFire is an advanced malware analysis service integrated into Palo Alto Networks firewalls, and it plays a significant role in the PCNSE exam. Candidates need to understand how WildFire detects zero-day threats by analyzing suspicious files in a cloud-based sandbox environment. The exam covers how to:
Enable and configure WildFire analysis on a firewall.
Forward suspicious files (e.g., PDFs, executables) for analysis.
Manage Wildfire logs and alerts.
Interpret WildFire verdicts automatically to respond to findings. Knowledge of integrating WildFire with other Palo Alto products to enhance threat detection capabilities is essential for exam success.
The VM-Series Firewalls are virtualized versions of Palo Alto Networks next-generation firewalls designed for deployment in private and public cloud environments such as AWS, Azure, and GCP. The PCNSE exam includes questions about:
Deploying VM-Series Firewalls: Understanding virtualized environments, including single-tenant and multi-tenant deployments.
Configuring network interfaces: such as those in cloud environments like VPCs (Virtual Private Clouds) in AWS or VNets in Azure.
Scaling: How to manage elastic scaling and high availability in cloud environments.
Licensing and Automation: Knowledge of the VM-Series licensing models and automating deployments with infrastructure-as-code (IaC) tools like Terraform and Ansible.

Question #1
A customer wants to enhance the protection provided by their Palo Alto Networks NGFW
deployment to cover public-facing company-owned domains from misconfigurations that
point records to third-party sources. Which two actions should the network administrator
perform to achieve this goal? (Choose two)
A. Verify the NGFWs have the Advanced DNS Security and Advanced Threat Prevention
licenses installed and validated
B. Create or update a Vulnerability Protection profile to the DNS Policies / DNS Zone
Misconfiguration section, then add the domains to be protected
C. Verify the NGFWs have the Advanced DNS Security and Advanced URL Filtering
licenses installed and validated
D. Create or update an Anti-Spyware profile, go to the DNS Policies / DNS Zone
Misconfiguration section, then add the domains to be protected
Correct Answer(s):
A. Verify the NGFWs have the Advanced DNS Security and Advanced Threat Prevention
licenses installed and validated
D. Create or update an Anti-Spyware profile, go to the DNS Policies / DNS Zone
Misconfiguration section, then add the domains to be protected
Explanation:
To protect public-facing company-owned domains from DNS misconfigurations—such as CNAME, MX, or NS records pointing to expired or third-party domains—the Palo Alto Networks NGFW must leverage Advanced DNS Security, introduced in PAN-OS 11.2.
Here’s what’s required: ✅ A. Licensing Validation
The firewall must have Advanced DNS Security and Advanced Threat Prevention licenses installed and active.
These licenses enable real-time inspection and protection against DNS hijacking and misconfiguration attacks. ✅ D. Anti-Spyware Profile Configuration
DNS Zone Misconfiguration protection is configured within an Anti-Spyware profile, not Vulnerability Protection.
Navigate to Objects > Security Profiles > Anti-Spyware, then go to the DNS Policies tab.
Under DNS Zone Misconfiguration, add the public-facing domains to be monitored.
Attach this profile to relevant Security Policy rules to enforce protection.
❌ Why the Other Options Are Incorrect: B. Vulnerability Protection profile → DNS misconfiguration detection is not part of Vulnerability Protection. It belongs in Anti-Spyware.
C. Advanced URL Filtering license → Not required for DNS Zone Misconfiguration protection. URL Filtering handles web traffic, not DNS records.

Let me know if you’d like help crafting a DNS protection policy or simulating a misconfiguration detection scenario.
Question #2
How can a firewall be set up to automatically block users as soon as they are found to
exhibit malicious behavior via a threat log?
A. Configure a dynamic address group for the addresses to be blocked with the tag
"malicious." Add a Log Forwarding profile to the other policies, which adds the "malicious"
tag to these addresses when logs are generated in the threat log. Under Device > User
Identification > Trusted Source Address, add the condition "NOT malicious."
B. Configure a dynamic user group for the users to be blocked with the tag "malicious."
Add a Log Forwarding profile to the other policies, which adds the "malicious" tag to these
users when logs are generated in the threat log. Create policies to block traffic from this
user group.
C. Configure the appropriate security profiles for Antivirus, Anti-Spyware, and Vulnerability
Prevention, create signature policies for the relevant signatures and/or severities. Under
the "Actions" tab in "Signature Policies," select "block-user."
D. N/A
Correct Answer(s):
B. Configure a dynamic user group for the users to be blocked with the tag "malicious."
Add a Log Forwarding profile to the other policies, which adds the "malicious" tag to these
users when logs are generated in the threat log. Create policies to block traffic from this
user group.
Explanation:
To automatically block users exhibiting malicious behavior based on threat log entries in a Palo Alto Networks firewall, the solution must leverage dynamic user groups and log forwarding to tag and block users dynamically. The firewall’s User-ID feature, combined with Log Forwarding Profiles, allows tagging users based on threat log events (e.g., malware detection) and applying policies to block them.
Correct Answer B. Configure a dynamic user group for the users to be blocked with the tag "malicious." Add a Log Forwarding profile to the other policies, which adds the "malicious" tag to these users when logs are generated in the threat log. Create policies to block traffic from this user group.: Step 1: Create a dynamic user group under Objects > Dynamic User Groups with a match condition for the tag "malicious" (e.g., tag eq malicious). This group dynamically includes users tagged with "malicious" based on threat log events. Step 2: Configure a Log Forwarding Profile under Objects > Log Forwarding, adding a match list for Threat logs (e.g., severity: critical, high) with an action to tag the source user with "malicious" (under User Tag > Tag). Step 3: Attach the Log Forwarding Profile to relevant security policies under Policies > Security > Actions > Log Forwarding to trigger tagging when threats are detected. Step 4: Create a security policy to block traffic from the dynamic user group (under Policies > Security, set Source User to the "malicious" dynamic user group, action: deny).
This setup ensures users are automatically tagged and blocked when malicious behavior is detected in threat logs (e.g., malware or exploits). Example: A user downloading malware triggers a threat log, gets tagged "malicious," and is blocked by a deny policy.
Why Other Options Are Incorrect A. Configure a dynamic address group for the addresses to be blocked with the tag "malicious." ... Under Device > User Identification > Trusted Source Address, add the condition "NOT malicious.":
While dynamic address groups can tag IP addresses, the question focuses on blocking users, not IPs. Additionally, Device > User Identification > Trusted Source Address does not exist in PAN-OS; User-ID configurations are under User Mapping or Dynamic User Groups, and "NOT malicious" is not a valid condition, making this option incorrect.
C. Configure the appropriate security profiles for Antivirus, Anti-Spyware, and Vulnerability Prevention, create signature policies for the relevant signatures and/or severities. Under the "Actions" tab in "Signature Policies," select "block-user.":
Security profiles (Antivirus, Anti-Spyware, Vulnerability Protection) define actions like block or alert for traffic, not users. There is no "Signature Policies" section or "block-user" action in PAN-OS security profiles. Blocking users requires User-ID and dynamic user groups, not signature-based actions, making this option invalid.
D. N/A:
This option implies no solution exists, which is incorrect since dynamic user groups with log forwarding provide a clear method to block users based on threat logs.
Technical Details
Configuration: Create dynamic user group: Objects > Dynamic User Groups, set match to tag eq malicious. Create Log Forwarding Profile: Objects > Log Forwarding, add match list for Threat logs, set action to tag user with "malicious". Attach to security policy: Policies > Security > Actions > Log Forwarding.
Create block policy: Policies > Security, set Source User to the dynamic user group, action: deny. CLI: set user-id dynamic-user-group match tag malicious, set log-settings profiles match-list log-type threat tag malicious.
Monitoring: Check tagged users in Monitor > Logs > User-ID or CLI (show user ip-user-mapping all). Best Practice: Use specific threat severities (e.g., critical, high) in the Log Forwarding Profile to avoid over-tagging.
PCNSE Relevance
The PCNSE exam tests your ability to use User-ID and dynamic user groups for automated policy enforcement based on threat detection, a key feature for dynamic security responses.

Question #3
What must be taken into consideration when preparing a log forwarding design for all of a
customer’s deployed Palo Alto Networks firewalls?
A. The logs will not contain the names of the identified applications unless the "Enable
enhanced application logging" option is selected
B. Traffic and threat logs will not be forwarded unless the relevant Log Forwarding profile is
attached to the security rules
C. App-ID engine will not identify any application traffic unless the "Enable enhanced
application logging" option is selected
D. Traffic and threat logs will not be forwarded unless the relevant Log Forwarding profile is selected in "Logging and Reporting Settings"
Correct Answer(s):
B. Traffic and threat logs will not be forwarded unless the relevant Log Forwarding profile is
attached to the security rules
Explanation:
When designing log forwarding for Palo Alto Networks firewalls, one of the most critical considerations is how Security Policy rules interact with Log Forwarding profiles. Specifically:
Traffic and Threat logs are only forwarded if a Log Forwarding profile is explicitly attached to the security rule that generates those logs.
This means that even if you've configured syslog, SNMP, email, or HTTP server profiles, no logs will be sent unless the forwarding profile is linked to the relevant rules.
This design ensures granular control over what logs are forwarded and where, aligning with compliance and operational needs.
❌ Why the Other Options Are Incorrect: A. Enhanced Application Logging → This affects additional metadata visibility, not basic application identification or log forwarding behavior.
C. App-ID engine won’t identify traffic without enhanced logging → Incorrect. App-ID works independently of enhanced logging. It identifies applications by default.
D. Logging and Reporting Settings → These settings control global logging behavior, but do not override the need to attach Log Forwarding profiles to individual rules.
How is Perfect Forward Secrecy (PFS) enabled when troubleshooting a VPN Phase 2
mismatch?
A. Enable PFS under the IKE Gateway advanced options
B. Enable PFS under the IPsec Tunnel advanced options
C. Select the appropriate DH Group under the IPsec Crypto profile
D. Add an authentication algorithm in the IPsec Crypto profile
Correct Answer(s):
C. Select the appropriate DH Group under the IPsec Crypto profile
Explanation:
Perfect Forward Secrecy (PFS) ensures that a new Diffie-Hellman (DH) key exchange is performed for every Phase 2 (IPsec SA) negotiation. This guarantees that if one key is compromised, it cannot be used to decrypt past or future sessions.
PFS is not configured under IKE Gateway (Phase 1) → that’s for IKE SA negotiation.
PFS is part of IPsec Phase 2 negotiation and is enabled in the IPsec Crypto Profile by selecting a DH Group (e.g., Group 2, Group 5, Group 14, etc.).
✅ Correct: C. Select the appropriate DH Group under the IPsec Crypto profile
This explicitly enables Perfect Forward Secrecy for Phase 2 negotiations.
❌ Incorrect: A. Enable PFS under the IKE Gateway advanced options
PFS is not configured in Phase 1 (IKE Gateway).
B. Enable PFS under the IPsec Tunnel advanced options
There’s no direct toggle here; it references the Crypto Profile instead.
D. Add an authentication algorithm in the IPsec Crypto profile
Authentication (e.g., SHA256, SHA512) is different from PFS and does not enable it.

“To enable Perfect Forward Secrecy, select a Diffie-Hellman group in the IPsec Crypto Profile.”
Question #5
A company CISO updates the business Security policy to identify vulnerable assets and
services and deploy protection for quantum-related attacks. As a part of this update, the
firewall team is reviewing the cryptography used by any devices they manage. The firewall
architect is reviewing the Palo Alto Networks NGFWs for their VPN tunnel configurations. It
is noted in the review that the NGFWs are running PAN-OS 11.2. Which two NGFW
settings could the firewall architect recommend to deploy protections per the new policy?
(Choose two)
A. IKEv1 only to deactivate the use of public key encryption
B. IKEv2 with Hybrid Key exchange
C. IKEv2 with Post-Quantum Pre-shared Keys
D. IPsec with Hybrid ID exchange
Correct Answer(s):
B. IKEv2 with Hybrid Key exchange
C. IKEv2 with Post-Quantum Pre-shared Keys
Explanation:
With PAN-OS 11.2, Palo Alto Networks NGFWs support quantum-resistant VPN configurations using two key standards:
✅ B. IKEv2 with Hybrid Key Exchange
Based on RFC 9242 and RFC 9370, this method uses multiple Key Exchange Mechanisms (KEMs)—including post-quantum algorithms like Crystals-Kyber, BIKE, HQC—alongside traditional Diffie-Hellman groups.
The result is a hybrid key that remains secure even if one KEM is compromised.
This protects against Harvest Now, Decrypt Later (HNDL) attacks by ensuring long-term confidentiality.
✅ C. IKEv2 with Post-Quantum Pre-shared Keys (PPKs)
Based on RFC 8784, this method uses pre-shared keys that are quantum-safe.
It’s simpler to deploy and provides defense-in-depth when used alongside hybrid key exchange.
Ideal for environments where full hybrid KEM negotiation isn’t feasible or where simplicity is preferred.
❌ Why the Other Options Are Incorrect: A. IKEv1 only to deactivate public key encryption → IKEv1 is deprecated and lacks support for post-quantum features. It’s less secure and should be avoided.
D. IPsec with Hybrid ID exchange → No such configuration exists. Hybrid key exchange applies to IKEv2, not IPsec phase directly.
