Palo Alto Networks NetSec-Analyst 認定試験の出題範囲：

トピック	出題範囲
トピック 1	Management and Operations: This section of the exam measures the skills of Security Operations Professionals and covers the use of centralized management tools to maintain and monitor firewall environments. It focuses on Strata Cloud Manager, folders, snippets, automations, variables, and logging services. Candidates are also tested on using Command Center, Activity Insights, Policy Optimizer, Log Viewer, and incident-handling tools to analyze security data and improve the organization overall security posture. The goal is to validate competence in managing day-to-day firewall operations and responding to alerts effectively.
トピック 2	Object Configuration Creation and Application: This section of the exam measures the skills of Network Security Analysts and covers the creation, configuration, and application of objects used across security environments. It focuses on building and applying various security profiles, decryption profiles, custom objects, external dynamic lists, and log forwarding profiles. Candidates are expected to understand how data security, IoT security, DoS protection, and SD-WAN profiles integrate into firewall operations. The objective of this domain is to ensure analysts can configure the foundational elements required to protect and optimize network security using Strata Cloud Manager.
トピック 3	Troubleshooting: This section of the exam measures the skills of Technical Support Analysts and covers the identification and resolution of configuration and operational issues. It includes troubleshooting misconfigurations, runtime errors, commit and push issues, device health concerns, and resource usage problems. This domain ensures candidates can analyze failures across management systems and on-device functions, enabling them to maintain a stable and reliable security infrastructure.
トピック 4	Policy Creation and Application: This section of the exam measures the abilities of Firewall Administrators and focuses on creating and applying different types of policies essential to secure and manage traffic. The domain includes security policies incorporating App-ID, User-ID, and Content-ID, as well as NAT, decryption, application override, and policy-based forwarding policies. It also covers SD-WAN routing and SLA policies that influence how traffic flows across distributed environments. The section ensures professionals can design and implement policy structures that support secure, efficient network operations.

Palo Alto Networks Network Security Analyst 認定 NetSec-Analyst 試験問題 (Q35-Q40):

質問 # 35
An organization is migrating its Palo Alto Networks firewall configurations to Panoram a. They have a complex hierarchy of security policies and objects that were previously managed on individual firewalls. They want to ensure that after migration, their policy structure is well-organized, easy to navigate, and supports future expansion while minimizing potential conflicts. What is the most appropriate Folder and Snippet (Shared Objects) strategy on Panorama?

A. Utilize a hierarchical folder structure that mirrors the organizational structure (e.g., 'Corporate', 'Data Center', 'Branch Offices') and use shared objects for common services, applications, and addresses at the 'Shared' or appropriate hierarchical folder level.
B. Export all configurations to XML and manually edit them to remove redundancies before importing into a single Panorama device group.
C. Avoid using folders and simply rely on policy rules for organization, leveraging tags for searchability.
D. Migrate all policies and objects to the 'Shared' folder. This simplifies management as everything is in one place.
E. Create a separate folder for each individual firewall. This isolates configurations and prevents accidental changes.

正解：A

解説：
Option C is the best practice. A hierarchical folder structure in Panorama allows for logical organization of policies and objects, making management intuitive and scalable. Placing common objects (snippets) at higher levels (like 'Shared' or a parent folder) ensures reusability and consistency across multiple device groups. This approach minimizes policy conflicts and simplifies future expansion. Option A leads to a cluttered 'Shared' folder. Option B defeats the purpose of centralized management. Option D lacks structural organization. Option E is manual and prone to errors.

質問 # 36
What are three valid information sources that can be used when tagging users to dynamic user groups? (Choose three.)

A. Custom API scripts
B. Firewall logs
C. Blometric scanning results from iOS devices
D. Security Information and Event Management Systems (SIEMS), such as Splun
E. DNS Security service

正解：A、B、E

質問 # 37
A financial institution has a requirement to send all traffic originating from the 'Finance' security zone, destined for external banking APIs (known IP ranges), through a dedicated, high-throughput internet link. Simultaneously, all other internet traffic from the 'Finance' zone should use the standard, lower-cost internet uplink. A PBF rule is configured as follows:

After deployment, users in the 'Finance' zone report that some API traffic is still going over the standard link. What is the most probable cause for this misbehavior?

A. The PBF rules are processed after security policy rules, causing the default security policy to take precedence for API traffic.
B. PBF rules only apply to inter-zone traffic; intra-zone traffic destined for external IPs will bypass PBF.
C. The 'Destination Zone' in both PBF rules should be explicitly set to 'any' instead of 'Untrust' for external destinations.
D. The 'Application' and 'Service' fields in the 'Finance_API_Route' rule should be more specific (e.g., 'web-browsing', 'ssl') to match API traffic accurately.
E. The 'Finance_Default_Route' rule is placed above the 'Finance_API_Route' rule in the PBF policy rulebase.

正解：E

解説：
PBF rules, like security policy rules, are processed in order from top to bottom. If the 'Finance_Default_Route' (which has a broader 'Destination Address: any') is placed above 'Finance_API_Route' (which has specific API IP ranges), all traffic from the 'Finance' zone destined for 'Untrust' will match the 'Finance_Default_Route' first and be forwarded out the standard link, before the more specific API rule is ever evaluated. To fix this, 'Finance_API_Route' must be placed above 'Finance_Default_Route'. Option A is incorrect; PBF rules are processed before security policy rules. Option C is incorrect; 'Untrust' is typically the correct zone for external destinations. Option D is plausible for better granularity but not the most probable cause of all API traffic misdirection, especially if the API traffic is using standard HTTP/HTTPS. Option E is incorrect; PBF applies to traffic that matches the rule criteria, regardless of intra-zone or inter-zone if the destination is external and matches the rule.

質問 # 38
Which type of object should be used to ensure that a Security policy rule automatically updates when a new virtual machine is spun up in a public cloud environment and assigned a specific tag?

A. Dynamic Address Group (DAG)
B. External Dynamic List (EDL)
C. Application Filter
D. Static Address Group

正解：A

解説：
Comprehensive and Detailed 150 to 250 words of Explanation From Palo Alto Networks Network Security Analyst Knowledge:
A Dynamic Address Group (DAG) is a powerful object type used to create agile security policies in environments where IP addresses change frequently, such as cloud-based infrastructures. Unlike a static group, where an analyst must manually add or remove IP addresses, a DAG uses tags as its membership criteria.
In this scenario, as a new virtual machine is deployed with a specific tag (e.g., "Web-Server"), the firewall or Panorama learns the IP address associated with that tag via the XML API or a VM Information Source. The firewall then automatically populates that IP address into the DAG. Because the Security policy refers to the DAG rather than specific IPs, the rule immediately applies to the new VM without requiring a manual configuration change or a commit. This automation is a fundamental objective for analysts working in DevOps or cloud-native environments, as it ensures that security scales at the same pace as the infrastructure.

質問 # 39
Actions can be set for which two items in a URL filtering security profile? (Choose two.)

A. Allow List
B. Custom URL Categories
C. Block List
D. PAN-DB URL Categories

正解：A、C
