20+ practice questions focused on Manage, Monitor and Operate — one of the most tested topics on the Palo Alto Networks Certified Network Security Engineer PCNSE exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Manage, Monitor and Operate PracticeA security administrator notices that a specific user is generating excessive logs due to repeated authentication failures. The administrator wants to see only failed authentication events for that user in the monitor tab. Which filter string should be used in the log viewer?
Explanation: The filter (addr.src eq user@domain.com) and (eventid eq auth-fail) uses the proper source address field (addr.src) to match the user's IP or identity and the exact event ID for authentication failures (auth-fail). This combination ensures only failed authentication events from that specific user are displayed in the monitor tab, meeting the administrator's requirement precisely.
A firewall is configured with two ISPs for redundancy. The administrator wants to ensure that traffic from internal users is load-balanced across both links based on source IP. Which configuration method should be used?
Explanation: D is correct because ECMP (Equal-Cost Multi-Path) with source IP hash enables the firewall to load-balance traffic across multiple equal-cost routes by hashing the source IP address, ensuring that all packets from the same source IP consistently use the same link. This method provides per-source-IP stickiness while distributing traffic across both ISPs, meeting the requirement for load balancing based on source IP.
A firewall is deployed in an Active/Passive HA pair. The administrator notices that the passive firewall is not synchronizing configuration changes. The 'show high-availability state' command shows the passive firewall in a 'non-functional' state. What is the most likely cause?
Explanation: The passive firewall showing a 'non-functional' state in an Active/Passive HA pair most likely indicates a version mismatch. PAN-OS requires both firewalls in an HA pair to run the exact same software version for configuration synchronization to work. If the passive firewall is running a different PAN-OS version, it cannot properly interpret or apply the configuration from the active firewall, causing it to enter a non-functional state.
Which TWO of the following are valid methods to upgrade the PAN-OS software on a firewall? (Choose two.)
Explanation: Option B is correct because PAN-OS images can be downloaded from the Palo Alto Networks Customer Support Portal and then uploaded/installed through the firewall's web interface (Device > Software), which is a standard supported upgrade method. Option C is correct because the CLI supports upgrading directly by specifying a URL, e.g., 'request system software upgrade' with an image URL, allowing the firewall to fetch and install the software. Option A is not a valid method since PAN-OS does not support installing software images directly from a USB drive inserted into the firewall. Option D is incorrect because FTP is not a supported transfer/installation mechanism for PAN-OS upgrades. Option E is incorrect because there is no email-to-PAN-OS feature for delivering and installing software images.
Which THREE of the following are valid actions that can be taken on a dynamic block list entry? (Choose three.)
Explanation: In a dynamic block list (DBL), the supported operations are adding an IP address (B) to block it, removing an IP address (A) to unblock it, and viewing the current list of blocked IPs (C) to audit or verify entries. These three actions—add, remove, and view—map directly to the management functions of a dynamic block list, which is IP-based and populated dynamically. Adding a username (D) is not valid because dynamic block lists operate on IP addresses, not user identities. Converting a dynamic entry to a static entry (E) is also not a valid action, since dynamic and static block lists are separate constructs and entries are not converted between them.

Practice all Manage, Monitor and Operate questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Manage, Monitor and Operate. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Manage, Monitor and Operate questions on the PCNSE frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
