Palo Alto Networks PCNSE Exam Questions Instant Access

Question 1

A company needs to preconfigure firewalls to be sent to remote sites with the least amount of reconfiguration. Once deployed, each firewall must establish secure tunnels back to multiple regional data centers to include the future regional data centers.

Which VPN configuration would adapt to changes when deployed to the future site?

APreconfigured GlobalProtect satellite

BPreconfigured GlobalProtect client

CPreconfigured IPsec tunnels

DPreconfigured PPTP Tunnels

Answer : A

Question 2

How is Perfect Forward Secrecy (PFS) enabled when troubleshooting a VPN Phase 2 mismatch?

AEnable PFS under the IKE Gateway advanced options

BEnable PFS under the IPsec Tunnel advanced options

CSelect the appropriate DH Group under the IPsec Crypto profile

DAdd an authentication algorithm in the IPsec Crypto profile

Answer : A

Perfect Forward Secrecy (PFS) ensures unique session keys per VPN session, enabled under the IKE Gateway advanced options (Option A) by selecting a Diffie-Hellman (DH) group. This resolves Phase 2 mismatches if the peer requires PFS.

Option B (IPsec Tunnel) doesn't directly control PFS. Option C (DH Group in IPsec Crypto) is related but not the enablement point. Option D (authentication algorithm) is unrelated. Documentation specifies IKE Gateway for PFS.

Question 3

An administrator plans to deploy 15 firewalls to act as GlobalProtect gateways around the world. Panorama will manage the firewalls.

The firewalls will provide access to mobile users and act as edge locations to on-premises infrastructure. The administrator wants to scale the configuration out quickly and wants all of the firewalls to use the same template configuration.

Which two solutions can the administrator use to scale this configuration? (Choose two.)

Acollector groups

Btemplate stacks

Cvirtual systems

Dvariables

Answer : B, D

When deploying a large number of firewalls, such as 15 GlobalProtect gateways around the world, it's crucial to have a scalable configuration approach. Panorama offers several features to help scale configurations efficiently:

B . Template stacks:

Template stacks in Panorama allow administrators to create a collection of configuration templates that can be applied to multiple firewalls or device groups. This enables the consistent deployment of shared settings (such as network configurations, security profiles, etc.) across all managed firewalls, ensuring uniformity and reducing the effort required to manage individual firewall configurations.

D . Variables:

Variables in Panorama provide a way to customize template configurations for individual firewalls or device groups without altering the overall template. For example, a variable can be used to define a unique IP address, hostname, or other specific settings within a shared template. When the template is applied, Panorama replaces the variables with the actual values specified for each device or device group, allowing for customization within a standardized framework.

By using template stacks and variables, an administrator can rapidly deploy and manage configurations across multiple GlobalProtect gateways, ensuring consistency while still accommodating site-specific requirements. This approach streamlines the deployment process and enhances the manageability of a widespread GlobalProtect infrastructure.

Question 4

Why are external zones required to be configured on a Palo Alto Networks NGFW in an environment with multiple virtual systems?

ATo allow traffic between zones in different virtual systems without the traffic leaving the appliance

BTo allow traffic between zones in different virtual systems while the traffic is leaving the appliance

CExternal zones are required because the same external zone can be used on different virtual systems

DMultiple external zones are required in each virtual system to allow the communications between virtual systems

Answer : B

Question 5

Which log type would provide information about traffic blocked by a Zone Protection profile?

AData Filtering

BIP-Tag

CTraffic

DThreat

Answer : D

https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClhzCAC

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.

Question 6

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)

AIKEv1 only to deactivate the use of public key encryption

BIKEv2 with Hybrid Key exchange

CIKEv2 with Post-Quantum Pre-shared Keys

DIPsec with Hybrid ID exchange

Answer : B, C

Quantum-related attack protection requires cryptography resistant to quantum computing, such as post-quantum algorithms. In PAN-OS 11.2, IKEv2 with Hybrid Key Exchange (Option B) combines classical and quantum-resistant algorithms for key exchange, enhancing VPN security. IKEv2 with Post-Quantum Pre-shared Keys (PPK) (Option C) uses pre-shared keys designed to resist quantum attacks, supported in IKEv2 configurations.

Option A (IKEv1 only) weakens security by avoiding PFS and modern cryptography. Option D (IPsec with Hybrid ID exchange) is not a valid PAN-OS feature. Documentation confirms IKEv2 enhancements for quantum resistance.

Question 7

During a routine security audit, the risk and compliance team notices a series of WildFire logs that contain a "malicious" verdict and the action "allow." Upon further inspection, the team confirms that these same threats are automatically blocked by the firewalls the following day. How can the existing configuration be adjusted to ensure that new threats are blocked within minutes instead of having to wait until the following day?

AConfirm the file types and direction are configured correctly in the WildFire analysis profile

BConfigure the appropriate actions in the Antivirus security profile

CConfigure the appropriate actions in the File Blocking profile

DConfirm the file size limits are configured correctly in the WildFire general settings

Answer : B

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.
