Palo Alto Networks Certified Network Security Professional NetSec-Pro Exam Questions

Answer : C

When using AWS centralized deployments for Cloud NGFW, the service deploys NGFW instances into selected VPCs as additional workloads to secure that traffic.

''In centralized deployments, Cloud NGFW instances are deployed as security appliances within the selected VPCs, ensuring consistent traffic inspection and protection.''

This approach minimizes complexity and ensures direct security policy enforcement within AWS.

Answer : C

Advanced DNS Security uses a signature policy to sinkhole malicious DNS queries and prevent them from resolving.

''The DNS Security service integrates with Anti-Spyware profiles, and you must configure signature policy settings to sinkhole malicious queries. This proactively stops traffic to known malicious domains.''

(Source: Configure DNS Security)

Sinkholing ensures that DNS queries to malicious FQDNs are redirected to a safe IP, preventing compromise.

Answer : C

In cloud environments like Azure, the VM-Series NGFW is deployed to create Layer 3 segmentation zones closest to the application workloads.

''In Azure, deploy VM-Series firewalls in Layer 3 mode to enforce security policies closest to private applications, meeting strict compliance and segmentation requirements.''

Layer 3 segmentation ensures security policies are enforced at the right boundary to isolate traffic within Azure's virtual networks.

Answer : A, C

Blocking non-compliant SSH versions and failing certificate validations are fundamental security measures:

Block sessions when certificate validation fails

''The SSH Proxy profile should block sessions that fail certificate validation to ensure that only trusted hosts are allowed.''

Block connections using non-compliant SSH versions

Older SSH versions may have vulnerabilities or lack modern encryption algorithms.

''To enforce stronger security, block SSH sessions that use older or deprecated versions of the SSH protocol that do not comply with your security posture.''

Together, these measures minimize the risk of MITM attacks and secure SSH traffic.

Answer : B

Enterprise DLP Profile is specifically designed to detect and log data exfiltration attempts, including those involving confidential or sensitive data.

''Enterprise DLP logs capture incidents involving potential data exfiltration. They help identify sensitive data transfers, even in seemingly legitimate traffic.''

File Blocking and Vulnerability Protection handle files or exploit detection, while WildFire focuses on malware analysis---not direct data exfiltration.

Answer : B

IoT Security uses MAC address, device manufacturer, and OS information to identify and classify devices via Device-ID.

''IoT Security uses passive network traffic analysis to fingerprint devices based on the MAC address, manufacturer, and operating system to ensure accurate classification.''

(Source: IoT Security Device-ID and Classification)

These attributes provide a robust, manufacturer-agnostic method to fingerprint IoT devices.

Answer : D

The firewall must be running a PAN-OS version that is supported by Panorama. This means that Panorama must be running the same or a newer PAN-OS version as the one being installed on the firewalls to maintain compatibility.

''Before you upgrade the firewall, ensure that Panorama is running the same or a later PAN-OS version than the firewall. Panorama must always be at the same or a higher version to maintain compatibility.''
