Palo Alto Networks PAN-NSA Online Questions & Answers

• Question 91:

  A company wants to build Security policy rules based on user identity rather than changing IP addresses assigned by DHCP and remote access.

  Which Palo Alto Networks capability supports this requirement?

  A. DNS Security
  B. WildFire
  C. User-ID
  D. QoS
  C. User-ID

  ---

  Explanation

  Comprehensive and Detailed 150 to 250 words of Explanation From Palo Alto Networks Network Security Analyst Knowledge: User-ID is the capability that allows the firewall to map network traffic to individual users and groups instead of relying only on IP addresses. This is especially important in modern environments where users move between wired, wireless, and remote contexts, and where IP addresses can change frequently due to DHCP, VPN assignment, or mobility. Identity-based policy provides more durable and meaningful access control.

  Option A is incorrect because DNS Security is a threat-prevention capability focused on malicious DNS activity, not user identity mapping.

  Option B is incorrect because WildFire is used for malware analysis and signature generation. Option

  D is incorrect because QoS manages traffic priority and bandwidth, not identity-aware policy.

  For a Network Security Analyst, User-ID enables policy rules such as allowing specific departments to access approved applications while restricting others, regardless of the endpoint's current IP. This supports Zero Trust principles by centering control around verified identity rather than temporary network location. It also improves auditing and troubleshooting because policy decisions can be tied to real users and groups, making security operations more precise and easier to explain to stakeholders.

• Question 92:

  What is the benefit of the Command Center's centralized dashboard in Strata Cloud Manager (SCM)?

  A. Monitoring encryption for network performance optimization
  B. Using AI to predict and prevent potential security incidents
  C. Automatically patching security vulnerabilities
  D. Monitoring and managing threats and operational health
  D. Monitoring and managing threats and operational health

  ---

  Explanation

  Comprehensive and Detailed 150 to 250 words of Explanation From Palo Alto Networks Network Security Analyst Knowledge: The Command Center in Strata Cloud Manager (SCM) is designed as the "single pane of glass" for modern network security operations. Its primary benefit is providing a unified, centralized dashboard that aggregates data across the entire security estate, including Next-Generation Firewalls (NGFWs), Prisma Access, and Prisma SD-WAN.

  By utilizing the Command Center, a Network Security Analyst can gain real-time visibility into two critical areas: security posture (threats, vulnerabilities, and risky applications) and operational health (device status, connectivity, and performance metrics). This centralized view eliminates the need for analysts to pivot between different management consoles to understand the global health of their network. The dashboard highlights critical threats that require immediate attention and provides health scores for devices, allowing for proactive troubleshooting of potential outages before they impact the business. While SCM does leverage AI (AIOps) for predictive analysis, the fundamental "benefit" of the Command Center dashboard itself, as defined in Palo Alto Networks documentation, is the holistic monitoring and management of threats and health across the distributed enterprise.

• Question 93:

  An analyst is investigating why traffic for a proprietary internal tool is repeatedly identified as unknown-tcp.

  What is the most likely reason?

  A. The policy is using application-default
  B. The firewall lacks a matching App-ID signature
  C. The destination is using an FQDN object
  D. The rule has logging disabled
  B. The firewall lacks a matching App-ID signature

  ---

  Explanation

  Comprehensive and Detailed 150 to 250 words of Explanation From Palo Alto Networks Network Security Analyst Knowledge: The most likely cause is that the firewall does not have a signature capable of identifying the proprietary application. When traffic is classified as unknown-tcp, it means the session was seen and processed as TCP traffic, but App-ID did not find a known signature match for it. This is common for internal or custom-built applications that are not part of the standard application database.

  Option A is incorrect because application-default influences port enforcement after an application is identified; it does not explain why the application remains unidentified.

  Option C is incorrect because the use of an FQDN object affects address matching in policy, not application identification.

  Option D is incorrect because disabling logging may reduce visibility, but it does not cause the firewall to label the traffic as unknown-tcp.

  For a Network Security Analyst, the next step is usually to collect packet captures and examine the payload for unique patterns that can be used in a custom application signature. Once a reliable custom App-ID is created, the organization can enforce more granular policy and reporting for that traffic. Reducing unknown applications is an important objective because unknown traffic represents a visibility gap that can hide misuse or malicious activity.

• Question 94:

  An analyst needs to identify, in a graphical and near-real-time way, which users, applications, and threats are currently most active on the network.

  Which tool provides this view?

  A. Config Audit
  B. ACC
  C. Authentication Log
  D. Template Stack
  B. ACC

  ---

  Explanation

  Comprehensive and Detailed 150 to 250 words of Explanation From Palo Alto Networks Network Security Analyst Knowledge: The Application Command Center, or ACC, is the correct tool because it provides a graphical and aggregated view of current network activity across users, applications, threats, URLs, and bandwidth consumption. It is designed to help analysts quickly spot anomalies, heavy usage patterns, and emerging issues without having to begin in raw log data. This makes it especially useful for operational monitoring and initial threat hunting.

  Option A is incorrect because Config Audit is used to compare configuration versions and administrative changes, not live traffic patterns.

  Option C is incorrect because the Authentication Log only records authentication-related events and does not provide broad network activity visualization.

  Option D is incorrect because a Template Stack is part of centralized configuration management and is unrelated to monitoring current traffic behavior.

  For a Network Security Analyst, ACC is often the starting point when investigating unusual application activity, bandwidth spikes, or user behavior that may require deeper analysis. From ACC, the analyst can pivot into more detailed logs and policy contexts. This combination of high-level visibility and drill-down capability makes ACC one of the most valuable tools for quickly understanding what is happening across the environment at a given moment.

• Question 95:

  An administrator is using Strata Cloud Manager (SCM) and notices that several firewalls are reporting a low health score due to "Untrusted Certificates" being used for management.

  Which specific SCM dashboard provides the fastest way to identify which certificates are nearing expiration across the entire estate?

  A. Command Center
  B. Activity Insights
  C. Policy Optimizer
  D. Device Health Dashboard
  B. Activity Insights

  ---

  Explanation

  Comprehensive and Detailed 150 to 250 words of Explanation From Palo Alto Networks Network Security Analyst Knowledge: In a modern Palo Alto Networks environment managed by Strata Cloud Manager (SCM), the Activity Insights dashboard is specifically designed to provide visibility into operational risks that are not necessarily "threats" but impact the stability of the security posture. One of its core functions is monitoring the lifecycle of certificates used throughout the network, including those for SSL Decryption, GlobalProtect, and web interface management. While the Device Health Dashboard (Option D) provides a generalized health score based on operational metrics like CPU and memory, Activity Insights drills down into specific configuration risks such as expired or weak certificates. This allows a Network Security Analyst to proactively identify which firewalls or service profiles are at risk of service disruption before a certificate actually expires. By centralizing this information, SCM eliminates the need for analysts to manually check local certificate stores on dozens or hundreds of individual firewalls, significantly reducing administrative overhead and ensuring that secure management channels remain operational without interruption.

• Question 96:

  An organization wants to use Strata Cloud Manager to monitor firewall health over time and focus on issues that have persisted for a longer duration.

  Which SCM dashboard is intended for this type of analysis?

  A. Policy Optimizer
  B. Device Health Dashboard
  C. ACC
  D. URL Filtering Dashboard
  B. Device Health Dashboard

  ---

  Explanation

  Comprehensive and Detailed 150 to 250 words of Explanation From Palo Alto Networks Network Security Analyst Knowledge: The Device Health Dashboard in Strata Cloud Manager is intended for monitoring the health of managed firewalls over time and identifying issues based on how long they have persisted. This helps analysts distinguish temporary spikes from ongoing problems such as sustained resource pressure or repeated operational anomalies that may require remediation.

  Option A is incorrect because Policy Optimizer is focused on improving policy specificity and rule design, not operational health trending.

  Option C is incorrect because ACC provides aggregated visibility into applications, users, and threats, but it is not the primary SCM dashboard for device health duration analysis.

  Option D is incorrect because URL Filtering Dashboard is not the tool for long-term device condition tracking.

  For analysts, trend-based health monitoring is important because not every issue requires the same level of urgency. A short-lived event may be informational, while a chronic condition can indicate capacity limitations, misconfiguration, or instability. By focusing on duration and persistence, the Device Health Dashboard supports more effective prioritization and proactive maintenance. This helps security teams address underlying operational risks before they affect traffic handling or service availability.
