NetSec-Analyst Management And Operations — 15 Questions

Question 1

A security analyst notices that the Threat Prevention subscription on a firewall is expired, but the firewall still has its previously downloaded signature database. Why might this happen?

Accepted Answer

The firewall still has the previous signature database stored locally.. The firewall maintains the last downloaded signatures in its local database even after the subscription expires, but it will not fetch new updates until renewed.

Answer

The firewall is using a grace period provided by the license server.

Answer

The subscription is tied to the Panorama management server, not the firewall.

Answer

The update server is misconfigured to allow free updates.

Question 2

When migrating from local management to Strata Cloud Manager, what happens to the existing local security policies on the firewall?

Accepted Answer

They remain as they are until the administrator pushes a new configuration from SCM.. When a device is added to SCM for management, the SCM policies typically override or merge with the existing local policies, and administrators must perform a 'push' operation to unify.

Answer

They are exported to a CSV file for manual review.

Answer

They are moved to a 'Local-Only' device group.

Answer

They are automatically deleted to prevent conflict.

Question 3

An administrator is troubleshooting a synchronization issue between SCM and an on-premises firewall. Which log file is best for verifying communication between the two?

Accepted Answer

devsrvr.log. The 'cms' (Cloud Management System) or 'scm' logs are typically used to troubleshoot connectivity between the firewall and the cloud management service.

Answer

tlog.log

Answer

pan_config.log

Answer

mp-log system.log

Question 4

Which of the following is considered an operational task performed via the firewall Dashboard?

Accepted Answer

Monitoring system resource utilization.. Monitoring system resource utilization is an operational task because it involves ongoing observation of the firewall's health and performance metrics (CPU, memory, disk, session counts) via the Dashboard. The Dashboard in Palo Alto Networks firewalls provides real-time widgets and graphs for this purpose, falling under operational monitoring rather than configuration. Other options are configuration or maintenance tasks, not operational monitoring.

Answer

Updating the App-ID database.

Answer

Defining a security policy rule.

Answer

Creating an address object.

Question 5

Which action must an administrator perform after installing a new license key on an NGFW?

Accepted Answer

Retrieve license keys from the license server.. After installing a new license, it is best practice to retrieve the latest license information from the portal to ensure the device reflects the updated status.

Answer

Clear the configuration cache.

Answer

Reboot the firewall.

Answer

Reset the management plane.

Question 6

What is the primary purpose of the 'Commit' operation?

Accepted Answer

To apply configuration changes to the running system.. The commit operation saves the running configuration into the candidate configuration and activates it, applying the changes to the firewall's data plane.

Answer

To save the configuration to the local disk.

Answer

To verify if the configuration syntax is correct.

Answer

To reboot the firewall.

Question 7

If an administrator forgets the password for the 'admin' account, how can it be recovered?

Accepted Answer

Reboot into maintenance mode and follow the recovery sequence.. On newer PAN-OS versions, password recovery involves using the 'maintenance' mode during boot, which requires physical console access.

Answer

Use the 'Reset Password' button on the login screen.

Answer

Contact TAC for a universal override password.

Answer

Factory reset the device.

Question 8

Where can an administrator view the total number of sessions currently active on the firewall?

Accepted Answer

Dashboard > System Resources. The Dashboard > Session Browser or the 'show session info' CLI command provides this data.

Answer

Device > Setup > Session

Answer

Network > Interfaces

Answer

Monitor > Traffic Logs

Question 9

Which TWO of the following are valid methods for performing a configuration backup on a firewall?

Accepted Answer

Exporting the configuration file via Device > Setup > Operations.. Option C is correct because on Palo Alto Networks firewalls the Device > Setup > Operations page provides the 'Export named configuration snapshot' and 'Export configuration version' functions, which generate an XML configuration file that can be saved locally as a valid backup. Option D is correct because the same Operations area (or Panorama/expedition scheduling) allows you to schedule recurring configuration exports to a remote server (e.g., SCP/HTTPS), giving an automated, off-box backup. Option A is wrong because a hard reset wipes the configuration rather than preserving a copy of it. Option B is wrong because an interface status snapshot captures runtime/operational state, not the device configuration. Option E is wrong because 'save config' is not a valid configuration-backup command on these firewalls; the CLI uses 'save config to <filename>' only in specific contexts and the standard backup mechanism is the export/scheduled export, not a generic 'save config' command.

Answer

Performing a hard reset.

Answer

Taking a snapshot of the interface status.

Answer

Using the 'save config' command in the CLI.

Question 10

A security operations team wants to ensure that configuration changes on a Palo Alto Networks firewall are automatically backed up and that they can quickly roll back to a previous version if a change causes issues. They need to schedule automatic backups that include the complete configuration and device state. Which feature should they configure?

Accepted Answer

Configuration Versioning with Scheduled Snapshots. Configuration Versioning with Scheduled Snapshots is designed to automatically capture full configuration and device state at scheduled intervals. These snapshots are stored on the firewall and can be restored with a single operation, enabling quick rollback. Other options either export only configuration, manage settings centrally without backup, or handle logs, none of which provide the required automatic backup and rollback capability.

Answer

Panorama Template Stack

Answer

Log Forwarding Profile

Answer

Scheduled Config Export

Question 11

A security operations team wants to ensure that a critical change to a firewall's security policy is not accidentally left uncommitted after a maintenance window. They need to configure automatic commit reminders and enforce a commit after any configuration change. Which TWO settings or features should they use? (Choose two.)

Accepted Answer

Configure a scheduled commit using the PAN-OS XML API with a cron job on an external management server.. The Commit Reminder sends periodic alerts via email to prompt administrators to commit pending changes, directly preventing forgotten commits. For automatic enforcement, the PAN-OS XML API can be called by an external scheduler to perform commits at set times. Together, these provide both a reminder mechanism and an automated enforcement path, satisfying the team's requirements. Other options reference non-existent features or unrelated settings.

Answer

Enable 'Require Commit' under Device > Setup > Session, which forces a commit before any new session is allowed.

Answer

Set up a Commit Lock under Device > Setup > Management to prevent changes from being saved until committed.

Answer

Use the 'Auto Commit' option under Device > Setup > Management to automatically commit all changes at a scheduled time.

Question 12

A security operations team wants to automate the response to a specific threat: when a firewall detects a critical severity threat from an internal IP address, it should automatically add that IP to a dynamic block list and notify the team via Slack. Which Palo Alto Networks feature should be used to achieve this?

Accepted Answer

Automation with Dynamic Address Groups and HTTP Server profiles. Palo Alto Networks firewalls support automation through Dynamic Address Groups (DAGs) and HTTP Server profiles. DAGs can be updated dynamically based on external sources or log events. When a critical threat is detected, a log forwarding profile can be configured to trigger an action that tags the source IP, which then updates the DAG to block it. Simultaneously, an HTTP Server profile can send a webhook to Slack. This native automation meets the requirement without external scripting.

Answer

Dynamic User Groups with GlobalProtect

Answer

Threat Prevention profiles with block IP action

Answer

Log Forwarding profiles with syslog to a SIEM that triggers a script

Question 13

A security analyst is configuring a new firewall to send logs to an external syslog server. The analyst must ensure that logs are reliably delivered and that the firewall can continue to operate if the syslog server becomes unreachable. Which two actions should the analyst take? (Choose two.)

Accepted Answer

Create a syslog server profile that defines the server IP address, port, and format, then reference it in the Log Forwarding profile.. To forward logs to an external syslog server, the analyst must create a syslog server profile defining the server details and then reference it in a Log Forwarding profile applied to security policies. The firewall will buffer logs locally if the server is unreachable, ensuring continued operation. The other options are either incorrect steps or do not directly contribute to reliable external logging.

Answer

Enable 'Log at Session Start' for all security rules to ensure logs are generated even if the session is denied.

Answer

Set the syslog server as a 'Syslog' profile in the Log Forwarding profile and configure a fallback local logging option.

Answer

Configure a Service Route for the syslog traffic to use the management interface for guaranteed delivery.

Question 14

A security analyst notices that a firewall is dropping traffic from a specific internal subnet to an external server, even though a security policy exists to allow it. The analyst suspects that a policy-based forwarding (PBF) rule is redirecting the traffic. Which action should the analyst take to verify this?

Accepted Answer

Check the PBF rules in the firewall's web interface under Network > Policy-Based Forwarding.. To verify if a PBF rule is redirecting traffic, the analyst should directly check the configured PBF rules in the firewall's web interface under Network > Policy-Based Forwarding. Other methods like routing table, session details, or traffic logs do not provide definitive information about PBF rule matches. Thus, inspecting the PBF rules is the correct action.

Answer

Run the 'show routing route' command to view the routing table.

Answer

Review the Traffic logs for the subnet to see the 'Application' field.

Answer

Inspect the session details using 'show session all filter source <subnet>'.

Question 15

A network security administrator is configuring a firewall to send logs to an external syslog server. The administrator wants to ensure that if the syslog server becomes unreachable, the firewall continues to log locally and does not drop traffic. Which configuration should be applied?

Accepted Answer

Create a Log Forwarding profile that includes both the syslog server and local logging, and apply it to security policies.. Log Forwarding profiles determine where logs are sent. By configuring a profile to send logs to both local disk and an external syslog server, the firewall will continue to log locally if the syslog server is unreachable. This does not impact traffic flow, as logging is separate from security policy enforcement. Other options reference non-existent features or misuse existing ones.

Answer

Enable 'Log Redundancy' under Device > Setup > Logging to buffer logs when the syslog server is down.

Answer

Configure a Policy-Based Forwarding rule to redirect traffic to a local logging interface if the syslog server fails.

Answer

Configure a Syslog server profile with the 'Log to Disk' option enabled and set the action to 'Fail Open'.
