Which firewall models support this configuration?
- A. PA-7050, PA-1420, VM-Series, CN-Series
- B. PA-3260, PA-5410, PA-850, PA-460
- C. PA-455, VM-Series, PA-1410, PA-5450
- D. PA-5280, PA-7080, PA-3250, VM-Series
Answer: B
Explanation:
The Advanced Routing Engine (ARE) is supported on Palo Alto Networks firewalls that utilize the PAN-OS 11.0+ software and have the required hardware architecture. The supported models include PA-3200 Series, PA-5400 Series, PA-800 Series, and PA-400 Series. These models provide enhanced routing capabilities, including BGP, OSPF, and more complex routing policies.
PA-3260 and PA-5410 are part of the PA-3200 and PA-5400 Series, which are known to support ARE.
PA-850 and PA-460 are within the PA-800 and PA-400 Series, which also support ARE
NEW QUESTION # 32
What must be configured before a firewall administrator can define policy rules based on users and groups?
- A. Authentication profile
- B. User Mapping profile
- C. LDAP Server profile
- D. Group mapping settings
Answer: D
Explanation:
Before a firewall administrator can define policy rules based on users and groups, the Group Mapping settings must be configured. These settings enable the firewall to map users to their respective Active Directory (AD) groups. This mapping allows the firewall to use user and group information to create policy rules based on group membership.
NEW QUESTION # 33
After an engineer configures an IPSec tunnel with a Cisco ASA, the Palo Alto Networks firewall generates system messages reporting the tunnel is failing to establish. Which of the following actions will resolve this issue?
- A. Ensure that an active static or dynamic route exists for the VPN peer with next hop as the tunnel interface.
- B. Validate the tunnel interface VLAN against the peer's configuration.
- C. Configure the Proxy IDs to match the Cisco ASA configuration.
- D. Check that IPSec is enabled in the management profile on the external interface.
Answer: C
Explanation:
The Proxy IDs (or Traffic Selectors) define the local and remote subnets that are allowed to communicate over the IPSec tunnel. If the Proxy IDs on the Palo Alto Networks firewall do not match the configuration on the Cisco ASA, the tunnel will fail to establish because the firewalls won't agree on which traffic to encrypt. Ensuring that the Proxy IDs match between the Palo Alto Networks firewall and the Cisco ASA will resolve the issue.
NEW QUESTION # 34
A security administrator is creating a new custom report to get a consolidated view of network events and needs to select a database to query for the report data. Which valid set of databases is available for the task?
- A. Data Filtering, IP-Tag, User-ID, Endpoint Security
- B. System, Config, Authentication, Session Flow
- C. Traffic, User-ID, Application Statistics, HIP Match
- D. Threat, URL Filtering, WildFire Submissions, GlobalProtect
Answer: D
Explanation:
When generating custom reports on a Palo Alto Networks firewall, the administrator must first select the underlying database that the report will query. The firewall maintains two primary types of databases for reporting:Summary DatabasesandDetailed Logs. The Summary Databases aggregate data every 15 minutes for faster report generation, whereas Detailed Logs provide a granular look at every single event.
The valid databases available for custom reports include:
* Summary Databases:Traffic, Threat, URL Filtering, Application Statistics, and Tunnel Inspection.
* Detailed Logs:Traffic, Threat, URL Filtering, WildFire Submissions, Data Filtering, HIP Match, GlobalProtect, IP-Tag, User-ID, Decryption, Tunnel, Authentication, and SCTP.
OptionAis the correct answer because all four components (Threat, URL Filtering, WildFire Submissions, and GlobalProtect) are distinct, valid database types that can be selected from the "Database" dropdown menu in the Custom Report configuration (found underMonitor > Manage Custom Reports > Add).
Option B is also composed of valid databases; however, in the context of Palo Alto Networks certification objectives, Option A is typically the highlighted set for demonstrating visibility into security-related network events. Option C is incorrect because "Endpoint Security" is not a valid database name in the firewall's reporting engine (the firewall uses "HIP Match" for host information). Option D is incorrect because the " Config" and "System" logs are generally viewed through the standard Log Viewer and are not available as source databases for the Custom Report builder, nor is there a "Session Flow" database in this context.
NEW QUESTION # 35
An organization's Security policy states that for all outbound web traffic, the TCP session to the external web server must be established by the firewall, not the user's workstation. This requires configuring user web browsers to point to the firewall. Authentication is also required.
Which solution on a PA-Series firewall meets these specific needs?
- A. GlobalProtect with User-ID
- B. Explicit proxy
- C. Transparent proxy
- D. Decryption policy with Authentication Portal
Answer: B
Explanation:
Explicit proxy requires user web browsers to be manually configured to send traffic to the firewall, and the firewall establishes the TCP session to external web servers on behalf of the client, enabling full mediation of outbound web traffic with integrated authentication support.
NEW QUESTION # 36
An engineer is implementing a new rollout of SAML for administrator authentication across a company's Palo Alto Networks NGFWs. User authentication on company firewalls is currently performed with RADIUS, which will remain available for six months, until it is decommissioned.
The company wants both authentication types to be running in parallel during the transition to SAML.
Which two actions meet the criteria? (Choose two.)
- A. Create and apply an authentication profile with the "SAML Identity Provider" Server Profile.
- B. Create an authentication sequence that includes both the "RADIUS" Server Profile and "SAML Identity Provider" Server Profile to run the two services in tandem.
- C. Create a testing and rollback plan for the transition from Radius to SAML, as the two authentication profiles cannot be run in tandem.
- D. Create and add the "SAML Identity Provider" Server Profile to the authentication profile for the
"RADIUS" Server Profile.
Answer: A,B
Explanation:
B). Create an authentication sequence that orders the RADIUS profile first followed by the SAML profile, allowing the firewall to attempt RADIUS authentication and fall back to SAML if needed, supporting tandem operation for administrator logins.
C). Create and apply an authentication profile using the SAML Identity Provider Server Profile, which can then be sequenced alongside the existing RADIUS profile without disrupting current authentication.
NEW QUESTION # 37
When creating a Log Forwarding profile on a PAN-OS firewall to direct logs to various external and internal systems, which set of methods is available?
- A. Panorama/Cloud logging, email, Syslog
- B. HTTP, RADIUS, SNMP
- C. Email, Syslog, NetFlow
- D. Syslog, Panorama, SD-WAN
Answer: A
Explanation:
Log Forwarding profiles in PAN-OS support forwarding logs to Panorama or cloud logging services, sending notifications via email, and exporting logs to external systems using Syslog, which together form the supported log forwarding mechanisms for centralized management and integration.
NEW QUESTION # 38
A network administrator is configuring path monitoring for a primary static route to ensure immediate failback from a backup route. The administrator wants the primary route to become active again without any delay as soon as its path is restored.
Which preemptive hold time value should the administrator configure to achieve this immediate failback?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
A preemptive hold time of 0 causes the firewall to immediately fail back to the primary static route as soon as path monitoring detects that the primary path is restored, with no delay before traffic is switched back.
NEW QUESTION # 39
An NGFW is deployed inline to inspect traffic without requiring any changes to existing IP addressing or routing configurations.
Which deployment mode is being used?
- A. VPN mode
- B. Layer 2 switching mode
- C. Virtual Wire / transparent mode
- D. Layer 3 routed mode
Answer: C
Explanation:
Virtual Wire (transparent) mode allows the NGFW to inspect traffic without modifying the network topology.
NEW QUESTION # 40
Which two statements apply to configuring required security rules when setting up an IPSec tunnel between a Palo Alto Networks firewall and a third- party gateway? (Choose two.)
- A. For incoming and outgoing traffic through the tunnel, separate rules must be created for each direction.
- B. For incoming and outgoing traffic through the tunnel, creating separate rules for each direction is optional.
- C. The IKE negotiation and IPSec/ESP packets are allowed by default via the intrazone default allow policy.
- D. The IKE negotiation and IPSec/ESP packets are denied by default via the interzone default deny policy.
Answer: B,C
Explanation:
In the Palo Alto Networks architecture, establishing a site-to-site VPN requires a clear understanding of how the Security Policy engine interacts with different traffic flows. According to technical documentation (Step 7 of the IPSec configuration guide), there are two distinct categories of traffic to consider: theControl Plane (negotiation) and theData Plane(transit).
First, the IKE negotiation (UDP 500/4500) and IPSec/ESP packets are directed at the firewall's own external interface. Because the peer gateway is usually reachable through the same zone as that interface (e.g.,
'Untrust'), the traffic is processed asintrazone. By default, PAN-OS includes anintrazone-defaultsecurity policy set to 'Allow'. Consequently, the tunnel can technically establish without an explicit rule, provided no manual 'Deny All' rule precedes it. This confirms that negotiation is allowed by default via the intrazone policy.
Second, regarding the data traffic entering or exiting the tunnel interface, the firewall applies standard zone- based inspection. While the firewall is stateful and policies are unidirectional, the documentation specifies that creating separate rules for each direction (one for inbound and one for outbound) isoptional. An administrator can choose to create two granular rules for tighter control or combine both directions into a single rule by adding both the internal and tunnel zones to the source and destination fields. This flexibility allows for a more streamlined rulebase while still meeting security requirements.
NEW QUESTION # 41
An administrator needs to perform several maintenance tasks on a managed firewall directly from the Panorama console, without using the Context Switch feature. Which set of tasks can the administrator fully execute from the Panorama UI? (Choose one answer)
- A. Create a new zone. Configure a new virtual router. View the local ACC on the firewall.
- B. Modify the IP address of a Layer 3 interface. Configure a new local administrator account. Edit a pre- rule.
- C. Download and install a new content update. View current firewall session details. Initiate a device reboot.
- D. Edit a post-rule. Create a new certificate profile. Configure the firewall's hostname.
Answer: D
Explanation:
Palo Alto Networks Panorama provides a centralized management platform that allows administrators to manage firewalls through two primary constructs:TemplatesandDevice Groups. When working directly within the Panorama UI (without switching to the firewall's context), an administrator interacts with these constructs to push configurations down to the managed devices.
The tasks listed inOption Crepresent the core functionality of Panorama's hierarchical management:
* Edit a post-rule:Security policies are managed withinDevice Groups. Post-rules are specific rules that appear after any locally defined rules on the firewall, allowing Panorama to enforce a "bottom-line" security posture across all managed devices.
* Create a new certificate profile:Object management, including certificate profiles, is handled within Templates or Device Groups (depending on scope) and can be easily defined at the Panorama level.
* Configure the firewall's hostname:System-level settings, such as hostnames, DNS, and NTP, are managed viaTemplates.
Conversely, the other options include tasks that generally require a direct connection or a "Context Switch" to the specific firewall's management plane. For example, viewingreal-time session details(Option A) or the local ACC(Option B) requires querying the specific firewall's dataplane. While Panorama can trigger a software update, performing adevice reboot(Option A) or managinglocal administrator accounts(Option D) are typically performed either locally or through the context switch to ensure the administrator is interacting with the device's specific local database rather than the global Panorama template.
NEW QUESTION # 42
Which configuration step is required when implementing a new self-signed root certificate authority (CA) certificate for SSL decryption on a Palo Alto Networks firewall?
- A. Disable all existing SSL decryption rules until the new certificate is fully propagated.
- B. Set the subordinate CA certificate as the default routing certificate for all network traffic.
- C. Import the new subordinate CA certificate into the trust stores of all client devices.
- D. Configure the subordinate CA to issue certificates with indefinite validity periods.
Answer: C
Explanation:
When implementing a new self-signed root certificate authority (CA) for SSL decryption on a Palo Alto Networks firewall, the subordinate CA certificate (which is generated by the firewall) must be imported into the trust stores of all client devices. This ensures that client devices trust the firewall as a valid certificate authority, enabling the firewall to decrypt and re-encrypt SSL traffic.
Importing the subordinate CA certificate into the client devices' trust stores is necessary for those devices to trust the new self-signed root CA and properly handle SSL decryption traffic.
NEW QUESTION # 43
An organization is migrating its data center to Amazon Web Services (AWS) and needs to deploy VM-Series firewalls to inspect all ingress and egress traffic. The solution must provide both resilience across multiple Availability Zones and the ability to scale horizontally.
Which combination of AWS services and Palo Alto Networks components is required for this use case?
- A. PAN-OS active/active high availability (HA) pair with an AWS Transit Gateway
- B. Single VM-Series firewall with an Elastic IP address that can be re-associated upon failure
- C. Amazon EC2 Auto Scaling group with VM-Series firewalls and an Amazon Gateway Load Balancer
- D. AWS Lambda function that monitors the firewall's health and re-routes traffic using the AWS API
Answer: C
Explanation:
Using VM-Series firewalls in an EC2 Auto Scaling group provides horizontal scale-out across multiple Availability Zones, and placing them behind an Amazon Gateway Load Balancer enables resilient, distributed traffic insertion for centralized inspection of ingress and egress flows while supporting automatic scaling and failover.
NEW QUESTION # 44
A network security engineer is reviewing the dynamic update settings for a fleet of firewalls in a financial institution that has a policy prioritizing operational stability above all else. The engineer notes that the current content update threshold is set to 24 hours.
Following the Palo Alto Networks recommended best practices for mission-critical deployments, which adjustment should be made to the threshold?
- A. Decrease to 12 hours.
- B. Reset to reconfirm 24 hours.
- C. Increase to 48 hours.
- D. Change to "download only" and schedule manual installation.
Answer: C
Explanation:
For mission-critical environments where stability is prioritized over rapid updates, Palo Alto Networks best practice is to increase the content update threshold to allow additional soak time for new releases, reducing the risk of introducing instability from newly published content updates.
NEW QUESTION # 45
An engineer is troubleshooting a failed inter-VSYS communication path between a DMZ-VSYS and an Internal-VSYS. The configuration includes separate virtual routers with next-vr static routes and appropriate Security policies within each VSYS allowing traffic to and from their external zones. Given that all routing and policy configurations within each individual VSYS are correct, what is the probable cause of the failure?
- A. A tunnel interface is required to connect the two virtual routers instead of using the next-vr option.
- B. The external zones were not assigned the External zone type, preventing them from connecting.
- C. The administrator did not configure Visible Virtual System.
- D. The intrazone-default policy is blocking the traffic because the two external zones are logically connected.
Answer: B
Explanation:
In a Multi-VSYS (Virtual System) architecture, Palo Alto Networks firewalls require a specific logical construct to facilitate communication that stays within the physical device. While traditional Layer 3 zones must be bound to physical interfaces, sub-interfaces, or aggregate groups,inter-VSYS communicationrelies on a specialized zone configuration known as theExternalzone type.
When traffic is routed between virtual routers using the next-vr command, the firewall needs a logical "hand- off" point to pass the session from one VSYS context to another. To achieve this, an engineer must create a zone in each VSYS and explicitly set itsType to External. These External zones do not attach to physical ports; instead, they serve as the entry and exit points for the internal backplane.
If the engineer attempts to use a standard Layer 3 zone for this purpose without an associated physical interface, the traffic will fail to egress the source VSYS or ingress the destination VSYS. Even if theSecurity PolicyandVirtual Routersettings are technically accurate, the session cannot be established because the logical path is incomplete. Therefore, assigning theExternal zone typeis a mandatory architectural requirement to bridge the gap between two logically separated virtual systems within the same hardware chassis.
NEW QUESTION # 46
An NGFW engineer is establishing bidirectional connectivity between the accounting virtual system (VSYS) and the marketing VSYS. The traffic needs to transition between zones without leaving the firewall (no external physical connections). The interfaces for each VSYS are assigned to separate virtual routers (VRs), and inter-VR static routes have been configured. An external zone has been created correctly for each VSYS. Security policies have been added to permit the desired traffic between each zone and its respective external zone. However, the desired traffic is still unable to successfully pass from one VSYS to the other in either direction.
Which additional configuration task is required to resolve this issue?
- A. Enable the "allow inter-VSYS traffic" option in both external zone configurations.
- B. Create a transit VSYS and route all inter-VSYS traffic through it.
- C. Add each VSYS to the list of visible virtual systems of the other VSYS.
- D. Create Security policies to allow the traffic between the two external zones.
Answer: A
Explanation:
External zones in Palo Alto firewalls require explicitly enabling "Allow traffic from other VSYS" (or similar inter-VSYS traffic allowance) in their zone configurations to permit bidirectional flow between VSYS without physical external routing, even when VSYS visibility, policies, and inter- VR routes are already configured.
Why VSYS Visibility Alone Fails
While adding VSYS to each other's visible list enables awareness of external zones across VSYS boundaries, traffic still drops unless the external zones themselves permit inter-VSYS traversal, as zones enforce isolation by default beyond mere visibility.
NEW QUESTION # 47
Palo Alto Networks NGFWs use SSL/TLS profiles to secure which two types of connections? (Choose two.)
- A. User Authentication
- B. NAT tables
- C. GlobalProtect Portal
- D. GlobalProtect Gateways
Answer: C,D
Explanation:
Palo Alto Networks Next-Generation Firewalls (NGFWs) use SSL/TLS profiles to secure connections for services such as GlobalProtect Gateways and GlobalProtect Portals. These profiles are used to manage the SSL/TLS encryption and decryption for secure communication between the firewall and clients (such as VPN clients for GlobalProtect). This helps ensure the confidentiality and integrity of the data during transmission.
NEW QUESTION # 48
Which two zone types are valid when configuring a new security zone? (Choose two.)
- A. Virtual Wire
- B. Intrazone
- C. Tunnel
- D. Internal
Answer: A,C
Explanation:
When configuring a new security zone on a Palo Alto Networks firewall, the two valid zone types are:
Tunnel: A Tunnel zone is used for traffic that is associated with a VPN tunnel, such as IPSec tunnels. Traffic passing through a tunnel interface is classified into this zone.
Virtual Wire: A Virtual Wire zone is used when a firewall operates in transparent mode (also known as Layer 2 mode). In this configuration, the firewall can inspect traffic without modifying the IP address structure of the network.
NEW QUESTION # 49
A network administrator needs to replace the default self-signed certificate on a firewall with one signed by the company's internal certificate authority (CA).
Which two firewall features would require this new certificate to be assigned via an SSL/TLS service profile? (Choose two.)
- A. RADIUS server authentication
- B. User-ID agent redistribution
- C. Authentication portal
- D. GlobalProtect gateway
Answer: B,C
Explanation:
User-ID agent redistribution uses SSL/TLS for secure communication between the firewall and User-ID agents, which requires a certificate assigned via an SSL/TLS service profile, and the Authentication Portal uses HTTPS for user authentication interactions, which also depends on a certificate provided through an SSL/TLS service profile.
NEW QUESTION # 50
Without performing a context switch, which set of operations can be performed that will affect the operation of a connected firewall on the Panorama GUI?
- A. Modification of local security rules, modification of a Layer 3 interface, modification of the firewall device hostname
- B. Restarting the local firewall, running a packet capture, accessing the firewall CLI
- C. Modification of post NAT rules, creation of new views on the local firewall ACC tab, creation of local custom reports
- D. Modification of pre-security rules, modification of a virtual router, modification of an IKE Gateway Network Profile
Answer: A
Explanation:
In Panorama, without performing a context switch, the administrator can perform local configuration tasks directly on the connected firewall. The following operations can be done:
Modification of local security rules: Security rules can be modified directly on the connected firewall from the Panorama GUI.
Modification of a Layer 3 interface: Changes to the Layer 3 interfaces on the connected firewall can be done from Panorama, without needing to switch to the firewall's local interface.
Modification of the firewall device hostname: The firewall's hostname can be changed via Panorama.
NEW QUESTION # 51
An enterprise uses GlobalProtect with both user- and machine-based certificate authentication and requires pre-logon, OCSP checks, and minimal user disruption. They manage multiple firewalls via Panorama and deploy domain-issued machine certificates via Group Policy.
Which approach ensures continuous, secure connectivity and consistent policy enforcement?
- A. Use a wildcard certificate from a public CA, disable all revocation checks to reduce latency, and manage certificate renewals manually on each firewall.
- B. Distribute root and intermediate CAs via Panorama template, use distinct certificate profiles for user versus machine certs, reference an internal OCSP responder, and automate certificate deployment with Group Policy.
- C. Configure a single certificate profile for both user and machine certificates. Rely solely on CRLs for revocation to minimize complexity.
- D. Deploy self-signed certificates on each firewall, allow IP-based authentication to override certificate checks, and use default GlobalProtect settings for user / machine identification.
Answer: B
Explanation:
To ensure continuous, secure connectivity and consistent policy enforcement with GlobalProtect in an enterprise environment that uses user- and machine-based certificate authentication, the approach should:
Distribute root and intermediate CAs via Panorama templates: This ensures that all firewalls managed by Panorama share the same trusted certificate authorities for consistency and security.
Use distinct certificate profiles for user vs. machine certificates: This enables separate handling of user and machine authentication, ensuring that both types of certificates are managed and validated appropriately.
Reference an internal OCSP responder: By integrating OCSP checks, the firewall can validate certificate revocation in real-time, meeting the security requirement while minimizing the overhead and latency associated with traditional CRLs (Certificate Revocation Lists).
Automate certificate deployment with Group Policy: This ensures that machine certificates are deployed in a consistent and scalable manner across the enterprise, reducing manual intervention and minimizing user disruption.
This approach supports the requirements for pre-logon, OCSP checks, and minimal user disruption, while maintaining a secure, automated, and consistent authentication process across all firewalls managed via Panorama.
NEW QUESTION # 52
An NGFW engineer is configuring multiple Panorama-managed firewalls to start sending all logs to Strata Logging Service. The Strata Logging Service instance has been provisioned, the required device certificates have been installed, and Panorama and the firewalls have been successfully onboarded to Strata Logging Service.
Which configuration task must be performed to start sending the logs to Strata Logging Service and continue forwarding them to the Panorama log collectors as well?
- A. Select the "Enable Duplicate Logging" option in the Cloud Logging section under Device --> Setup - -> Management in the appropriate templates.
- B. Modify all active Log Forwarding profiles to select the "Cloud Logging" option in each profile match list in the appropriate device groups.
- C. Select the "Enable Cloud Logging" option in the Cloud Logging section under Device --> Setup -
-> Management in the appropriate templates. - D. Enable the "Panorama/Cloud Logging" option in the Logging and Reporting Settings section under Device --> Setup --> Management in the appropriate templates.
Answer: A
Explanation:
For Panorama-managed firewalls already onboarded to Strata Logging Service, enabling duplicate logging allows logs to forward simultaneously to both the service and Panorama log collectors.
Configuration Location
This setting resides in the Cloud Logging section of Device > Setup > Management within Panorama templates applied to the firewalls. Selecting "Enable Duplicate Logging (Cloud and On-Premise)" ensures parallel forwarding without disrupting existing Panorama log collection.
