Free Practice Questions for Paloalto Networks NetSec-Pro Exam

Acomprehensive security approachuses:

User-IDfor identity-based policies

App-IDfor application-based security

Decryptionto inspect encrypted traffic

Security profilesto enforce protections

Dynamic updatesto ensure up-to-date threat coverage

“For comprehensive security, combine User-ID, App-ID, decryption, and security profiles. Keep the firewall updated with dynamic content updates to maintain the strongest security posture.”

(Source: Best Practices for Security Policy)

This ensures real-time, identity-aware, and application-centric security enforcement.

TheAnti-spyware profileincludes DNS-based protections like sinkholing and detection of DNS queries to malicious domains, offering real-time protection against attacks that exploit DNS misconfigurations.

“The Anti-Spyware profile protects against DNS-based threats by sinkholing DNS queries to malicious domains and detecting suspicious DNS activity, thus blocking data exfiltration and C2 communication.”

TheSP3 architectureof Palo Alto NGFWs ensures that additional security services (CDSS) only cause aminor reduction in performance, as traffic is inspected once in a single pass.

“The single-pass parallel processing (SP3) architecture performs application identification and security enforcement simultaneously in one pass, resulting in only minor performance impacts when enabling multiple security services.”

(Source: SP3 Architecture)

Unlike traditional multi-pass engines, SP3 architecture optimizes performance while delivering comprehensive security.

An ALG is designed toinspect and modify the payloadof application-layer protocols (like SIP, FTP, etc.) to manage dynamic port allocations and session information.

“Application Layer Gateways (ALGs) inspect the payload of certain protocols to dynamically manage sessions that use dynamic port assignments. By modifying payloads, the ALG ensures that NAT and security policies are correctly applied.”

When migrating from aperpetual VM-Series firewall license to a flexible VM licensing model, two critical steps are needed:

Allocate same number of vCPUs– This ensures that the VM-Series capacity remains consistent and avoids resource bottlenecks.

“When migrating perpetual VM-Series licenses to flexible VM licensing, allocate the same vCPU and memory resources to ensure equivalent performance.”

(Source: VM-Series Flexible Licensing Migration)

Limit to same security services– Flexible licensing requires maintaining the same security services to preserve licensing compliance.

“Ensure that you allow only the same security services on the flexible VM instance as were licensed on the perpetual VM.”

Device grouping rulesin SCM allow administrators toorganize firewalls into logical groupsand collectively manage updates or configuration pushes across those groups.

“SCM allows you to create device group rules, enabling streamlined management and collective updates of multiple NGFW instances.”

This approach ensures consistency in software versions and configuration baselines across large deployments.

To inspect SaaS app traffic (often encrypted), you must configure:

SSL Forward Proxy

“The SSL Forward Proxy decryption profile enables the firewall to decrypt outbound SSL traffic, essential for visibility into SaaS app usage.”

(Source: SSL Forward Proxy Overview)

Validate certificates

“Validating and deploying the appropriate root and intermediate CA certificates is critical for establishing trust and preventing SSL errors during decryption.”

(Source: Certificate Deployment and Validation)

Without these steps, SaaS decryption and policy enforcement would be incomplete.

For IoT Security toaccurately classify and monitorIoT devices, the following logs must be forwarded to Strata Logging Service:

Enhanced application logs– provide detailed application usage and behaviors, essential for profiling device types and roles.

“Enhanced Application logs provide additional context on IoT device behavior and usage patterns, and must be forwarded to Strata Logging Service for IoT Security to build accurate Device-ID profiles.”

(Source: IoT Security Logging Requirements)

Threat logs– essential for detecting suspicious or malicious activities by IoT devices.

“Threat logs are critical for identifying potential exploits or suspicious activities involving IoT devices and are required for accurate threat visibility within IoT Security.”

(Source: IoT Security Logs)

These logs collectively ensure accurate device classification and real-time threat visibility.
