PCNSA Device Management and Services Practice Test 4 — 15 Questions

Question 1

Refer to the exhibit. A security analyst reviews a traffic log entry in JSON format. Which firewall feature is responsible for including the 'user' field in the log?

Accepted Answer

User-ID. The 'user' field in a traffic log is populated by User-ID, which maps IP addresses to usernames by monitoring authentication events from Active Directory, LDAP, or terminal services agents. This allows the firewall to log and enforce policies based on user identity rather than just IP addresses.

Answer

Data Filtering

Answer

Captive Portal

Answer

GlobalProtect

Question 2

A network administrator needs to restrict which source IP addresses can access the firewall's web management interface. Which feature should be configured?

Accepted Answer

Management Profile. Management Profile. A Management Profile is a firewall configuration object that defines which services (e.g., HTTPS, SSH, ping) are allowed on a specific interface and, critically, which source IP addresses or subnets can access those services. By binding a Management Profile to an interface, the administrator can restrict web management access to only trusted source IPs, such as a management subnet. This is the intended and most secure method for controlling management plane access on Palo Alto Networks firewalls.

Answer

Access Control List on the data plane

Answer

Interface management settings

Answer

Security policy rule for management traffic

Question 3

An administrator wants to synchronize the firewall's clock with a central NTP server. Where is this configured?

Accepted Answer

Under Device > Setup > Services, NTP tab. NTP (Network Time Protocol) client configuration on a Palo Alto Networks firewall is performed under Device > Setup > Services, where the NTP tab allows you to specify primary and secondary NTP servers. This synchronizes the firewall's system clock, which is critical for accurate log timestamps, certificate validation, and security policy enforcement. The firewall acts as an NTP client, sending periodic NTP requests (typically using UDP port 123) to the configured servers.

Answer

Under Objects > Regions

Answer

Under Device > Licenses

Answer

Under Network > Interfaces, Management Interface

Question 4

A syslog server is only reachable through a specific interface on the firewall. To ensure syslog logs are sent via that interface, which configuration is required?

Accepted Answer

Set up a service route for syslog. Service routes in Palo Alto Networks firewalls allow you to specify which source interface or IP address is used for outbound traffic from the firewall itself, such as syslog, SNMP, or authentication. By configuring a service route for syslog, you ensure that syslog messages are sourced from the specific interface that can reach the syslog server, even if the routing table would otherwise choose a different path.

Answer

Configure a static route for the syslog server IP

Answer

Enable NAT on the syslog traffic

Answer

Use policy-based forwarding for syslog traffic

Question 5

After making configuration changes, an administrator clicks 'Commit' but the changes are not applied. What is the most likely cause?

Accepted Answer

Configuration validation errors exist. When an administrator clicks 'Commit' but the changes are not applied, the most likely cause is that configuration validation errors exist. The Palo Alto Networks firewall performs a validation check before committing; if any errors are found (e.g., invalid IP addresses, missing required fields, or conflicting rules), the commit is blocked and an error message is displayed. This ensures that only syntactically and semantically correct configurations are applied to the running state.

Answer

The commit is scheduled for a later time

Answer

The commit was canceled by another admin

Answer

The firewall is in multi-vsys mode and only the current vsys is committed

Question 6

For a firewall to communicate with Panorama for centralized management, which requirement must be met?

Accepted Answer

Panorama must be reachable via the management interface. For a firewall to communicate with Panorama for centralized management, the Panorama server must be reachable via the firewall's dedicated management interface (MGT). This is because the management interface is the default source for all management-plane traffic, including Panorama communications, unless explicitly overridden by a service route. Without reachability through this interface, the firewall cannot establish the required HTTPS or SSH connections to Panorama.

Answer

Both A and B are required

Answer

A service route must be configured for Panorama

Answer

A valid license for Panorama management is required

Question 7

A company requires automatic daily backups of the firewall configuration. Which method should be used?

Accepted Answer

Schedule a configuration backup under Device > Setup > Operations. The PAN-OS web interface provides a built-in scheduler under Device > Setup > Operations that allows administrators to automate daily configuration backups without external scripts or manual intervention. This method is the simplest and most reliable way to ensure consistent backups, as it leverages the firewall's native scheduling capability.

Answer

Backup the config using TFTP from the CLI

Answer

Write a script using the PAN-OS API to copy the running config

Answer

Use the 'Export Device State' feature manually

Question 8

An administrator wants to allow ping (ICMP) and SSH access on a data interface (e.g., ethernet1/1) for troubleshooting. Which configuration is required?

Accepted Answer

Configure an interface management profile on ethernet1/1. Interface management profiles control which management services (ping, SSH, HTTP, etc.) are permitted on a data interface.

Answer

Enable 'Management' profile on the VLAN interface

Answer

Create a security policy allowing ICMP and SSH inbound

Answer

Enable the service route for ping and SSH

Question 9

During troubleshooting, an administrator needs to review firewall system events such as user logins, configuration changes, and commit failures. Which log type should be examined?

Accepted Answer

System logs. System logs in Palo Alto Networks firewalls capture administrative and system-level events, including user logins, configuration changes, and commit failures. These logs are generated by the management plane and are essential for auditing and troubleshooting device management activities.

Answer

Threat logs

Answer

Traffic logs

Answer

URL filtering logs

Question 10

What is the purpose of the 'Telemetry' feature in PAN-OS?

Accepted Answer

To send anonymous device health and usage data to Palo Alto Networks. The Telemetry feature in PAN-OS sends anonymous device health and usage data to Palo Alto Networks to help improve product development and threat detection. This data includes information such as system resource utilization, feature usage statistics, and aggregate threat information, but does not include sensitive or personally identifiable information. It is an opt-in feature that enhances Palo Alto Networks' ability to provide proactive support and security updates.

Answer

To send logs to Panorama

Answer

To enable DNS proxy

Answer

To configure User-ID agent

Question 11

Refer to the exhibit. What is the PAN-OS version running on the firewall?

Accepted Answer

10.2.0. The PAN-OS version is determined by the first two digits of the version string displayed in the CLI output (e.g., '10.2.0'). In the exhibit, the firewall shows '10.2.0', which corresponds to PAN-OS 10.2.0. This is the correct version because the CLI command 'show system info' or the GUI dashboard displays the exact software version installed.

Answer

10.1.0

Answer

9.1.0

Answer

10.0.0

Question 12

Refer to the exhibit. What is the default gateway of the firewall?

Accepted Answer

10.0.0.1. The default gateway for a firewall is the IP address of the next-hop router that the firewall uses to reach networks not directly connected. In the exhibit, the route with destination 0.0.0.0/0 (the default route) points to next-hop 10.0.0.1, making 10.0.0.1 the default gateway. This is the standard behavior in PAN-OS: the default gateway is defined by the static default route, not by an interface IP.

Answer

ethernet1/1

Answer

10.0.0.0

Answer

0.0.0.0

Question 13

Refer to the exhibit. What is the status of the commit job?

Accepted Answer

Pending. The commit job status is 'Pending' because the commit operation has been initiated but not yet completed. In Palo Alto Networks firewalls, when a commit is in progress, the job status shows as 'Pending' until the configuration is successfully applied or an error occurs. The exhibit likely shows a commit job with a status of 'Pending', indicating that the system is still processing the configuration changes.

Answer

Completed

Answer

Canceled

Answer

Failed

Question 14

Which two authentication methods can be used for administrative access to the firewall's web interface? (Choose two.)

Accepted Answer

SAML. SAML (Security Assertion Markup Language) is correct because it enables single sign-on (SSO) for administrative access to the firewall's web interface, allowing integration with external identity providers (IdPs) such as Okta or Azure AD. The local database is correct because it is the default authentication method, where administrators are created and stored locally on the firewall, and credentials are verified against the internal user database. Both methods are natively supported in PAN-OS for web interface (GUI) access.

Answer

NTLM

Answer

OAuth

Answer

Kerberos

Question 15

Which three of the following are valid commit options in the PAN-OS GUI? (Choose three.)

Accepted Answer

Validate commit. The PAN-OS GUI provides a 'Validate commit' option that checks the configuration for errors before applying it. This is a standard commit option that ensures the candidate configuration is syntactically and semantically valid, reducing the risk of committing a broken configuration.

Answer

Force commit

Answer

Commit to Panorama
