PCNSE Practice Exam Questions with Answers Palo Alto Networks Certified Security Engineer (PCNSE) PAN-OS 11.0 Certification

When dealing with a false positive, particularly for a spyware threat detected through DNS queries (as indicated by the category "dns-c2"), the correct course of action involves creating an exception in the Anti-Spyware profile, not the Vulnerability Protection profile. This is because the Anti-Spyware profile in Palo Alto Networks firewalls is designed to detect and block spyware threats, which can include command and control (C2) activities often signaled by DNS queries.

The steps to configure an exception for this specific spyware signature (threat ID: 1000011111) are as follows:

• Navigate to Objects > Security Profiles > Anti-Spyware. This is where all the Anti-Spyware profiles are listed.
• Select the related Anti-Spyware profile that is currently applied to the security policy which is generating the false positive.
• Within the profile, go to the DNS Exceptions tab. This tab allows you to specify exceptions based on DNS signatures.
• Search for the related threat ID (in this case, 1000011111) and click enable to create an exception for it. By doing this, you instruct the firewall to bypass the detection for this specific signature, effectively treating it as a false positive.
• Commit the changes to make the exception active.

By following these steps, the administrator can effectively address the false positive without disabling the overall spyware protection capabilities of the firewall.

In the second image, VW ports mentioned are 1/5 and 1/7. Hence it can not be a part of any other routing. So if any traffic coming as ingress from 1/7, it has to go out via 1/5.

The egress interface for the traffic with ingress interface ethernet1/7, source 192.168.111.3, and destination 10.46.41.113 will be ethernet1/5. This is because the traffic will match the virtual wire with interfaces ethernet1/5 and ethernet1/7, which is configured to allow VLAN-tagged traffic with tags 10 and 201. The traffic will also match the security policy rule that allows traffic from zone Trust to zone Untrust, which are assigned to ethernet1/7 and ethernet1/5 respectively2. Therefore, the traffic will be forwarded to the same interface from which it was received, which is ethernet1/53.

Virtual Desktop Infrastructure (VDI) and Virtual Machine (VM) environments, such as Citrix XenApp and XenDesktop or VMWare Horizon and Vcenter, support access natively through HTML5. You can RDP, VNC, or SSH to these machines through Clientless VPN without requiring additional third-party middleware. In environments that do not include native support for HTML5 or other web application technologies supported by Clientless VPN, you can use third-party vendors, such as Thinfinity, to RDP through Clientless VPN.

Set the Action to take when matching a packet:

Forward—Directs the packet to the specified Egress Interface.

Forward to VSYS (On a firewall enabled for multiple virtual systems)—Select the virtual system to which to forward the packet.

Discard—Drops the packet.

No PBF—Excludes packets that match the criteria for source, destination, application, or service defined in the rule. Matching packets use the route table instead of PBF; the firewall uses the route table to exclude the matched traffic from the redirected port.

External zones are a unique zone type on Palo Alto Networks firewalls that facilitate the movement of traffic between virtual systems on the same physical appliance. These zones are required when multiple virtual systems (vsys) are configured on a single firewall and there is a need to allow inter-vsys traffic without the need for the traffic to leave the firewall and re-enter. An external zone is associated with a specific virtual system and enables traffic to pass from one virtual system to another securely, thereby simplifying traffic management and reducing the need for additional physical interfaces or external routing to handle inter-vsys communication.

For virtual systems (vSys) on a Palo Alto Networks firewall to communicate with each other, especially when separate virtual routers (VRs) are used for each vSys, the configuration must facilitate proper routing and security policy enforcement. The key aspects to focus on include:

A. External zones with the virtual systems added:

• External zones are special types of zones that are used to facilitate traffic flow between virtual systems within the same physical firewall. By adding virtual systems to an external zone, you enable them to communicate with each other, effectively bypassing the need for traffic to exit and re-enter the firewall.

D. Add a route with next hop next-vr by using the VR configured in the virtual system:

• When using separate VRs for each vSys, it's essential to configure inter-VR routing. This is done by adding routes in each VR with the next hop set to 'next-vr', specifying the VR of the destination vSys. This setup enables traffic to be routed from one virtual system's VR to another, facilitating communication between them.

E. Ensure the virtual systems are visible to one another:

• Visibility between virtual systems is a prerequisite for inter-vSys communication. This involves configuring the virtual systems in a way that they are aware of each other's existence. This is typically managed in the vSys settings, where you can specify which virtual systems can communicate with each other.

By focusing on these configuration details, the network security engineer can ensure that the virtual systems can communicate effectively, maintaining the necessary isolation while allowing the required traffic flow.

To enable XML API access to a firewall for automation from a network segment routed through a Layer 3 sub-interface, the most straightforward approach is to use an Interface Management profile.

C. This can be achieved by:

• Configuring an Interface Management profile and enabling HTTPS access on it. This profile defines management services that are permitted on the interface, including HTTPS, which is required for XML API access.
• Applying this Interface Management profile to the desired Layer 3 sub-interface. This action enables HTTPS access (and thus XML API access) on the sub-interface, allowing devices on the connected network segment to communicate with the firewall for automation purposes.

This solution allows for the secure extension of management capabilities to network segments without direct access to the dedicated management interface, facilitating automation and operational efficiency without necessitating changes to existing access configurations.

The Palo Alto Networks Best Practices for Anti-Spyware Profiles recommend enabling single-packet captures (PCAP) for medium, high, and critical severity threats. This allows for capturing the first packet of the malicious traffic for further analysis and investigation. PCAP should not be enabled for low and informational severity threats, as they generate a relatively high volume of traffic and are not particularly useful compared to potential threats2. References: Create the Data Center Best Practice Anti-Spyware Profile, Security Profile: Anti-Spyware, PCNSE Study Guide (page 57)

A syslog listener is the best choice for deploying User-ID to ensure maximum coverage in an environment with multiple forms of authentication. A syslog listener is a feature that enables the firewall or Panorama to receive syslog messages from other systems and parse them for IP address-to-username mappings. A syslog listener can collect user mapping information from a variety of sources, such as network access control systems, domain controllers, MDM solutions, VPN gateways, wireless controllers, proxies, and more2. A syslog listener can also support multiple platforms and operating systems, such as Windows, Linux, macOS, iOS, Android, etc3. Therefore, a syslog listener can provide a comprehensive and flexible solution for User-ID deployment in a large-scale network. References: Configure a Syslog Listener for User Mapping, User-ID Agent Deployment Guide, PCNSE Study Guide (page 48)

A device group is a logical grouping of firewalls that share the same security policy rules. A device group can contain multiple vsys and firewalls, including multi-vsys firewalls. A multi-vsys firewall can have each vsys in a different device group, depending on the desired security policy for each vsys. This allows for granular control and flexibility in managing multi-vsys firewalls with Panorama1. References: Device Group Push to a Multi-VSYS Firewall, Configure Virtual Systems, PCNSE Study Guide (page 50)

Palo Alto Networks recommends following a specific upgrade path when upgrading PAN-OS to ensure compatibility and minimize the risk of issues. The recommended path involves sequential upgrades through major releases.

B. The detailed upgrade path from PAN-OS 10.1 to 11.0.x involves:

• First, upgrading to the latest preferred maintenance release of the current PAN-OS version (10.1) to ensure that all the latest fixes and improvements are applied.
• Next, upgrading to the base version of the next major release (PAN-OS 10.2.0), followed by upgrading to the latest preferred maintenance release of PAN-OS 10.2. This step ensures that the firewall is on a stable and supported version before proceeding to the next major release.
• Finally, upgrading to the base version of PAN-OS 11.0 (11.0.0), followed by the desired PAN-OS 11.0.x version. This step completes the upgrade to the new major version, providing access to new features and improvements, such as TLSv1.3 support for management access.

This sequential upgrade path is designed to ensure a smooth transition between major versions, maintaining system stability and security.

For the transparent proxy method, the request contains the destination IP address of the web server and the proxy transparently intercepts the client request (either by being in-line or by traffic steering). There is no client configuration and Panorama is optional. Transparent proxy requires a loopback interface, User-ID configuration in the proxy zone, and specific Destination NAT (DNAT) rules. Transparent proxy does not support X-Authenticated Users (XAU) or Web Cache Communications Protocol (WCCP). https://docs.paloaltonetworks.com/pan-os/11-0/pan-os-new-features/networking-features/web-proxy

https://docs.paloaltonetworks.com/panorama/11-0/panorama-admin/manage-firewalls/transition-a-firewall-to-panorama-management/migrate-a-firewall-to-panorama-management Push the configuration bundle from Panorama to the newly added firewall to remove all policy rules and objects from its local configuration. This step is necessary to prevent duplicate rule or object names, which would cause commit errors when you push the device group configuration from Panorama to the firewall in the next step.

When building Security rules in a Device Group that need to allow traffic to specific users and groups defined in Active Directory, it's essential to have user and group information available in Panorama to select these entities for the rules.

D. A master device with Group Mapping configured must be set in the device group where the Security rules are configured:

• The concept of a "master device" in Panorama refers to a specific firewall that is designated to provide certain settings or information, such as user and group mappings from Active Directory, to Panorama. This information can then be used across other firewalls within the same device group.
• By configuring Group Mapping on a master device, Panorama can leverage this information to populate user and group objects. These objects can then be used in Security rules within the device group, allowing for the creation of policies that are based on user identity and group membership, as defined in Active Directory.
• This setup ensures that Panorama has the necessary context to apply user- and group-based policies accurately across the managed firewalls, facilitating centralized management and consistency in policy enforcement.

In an active/active high availability (HA) firewall pair, the firewall that is currently processing traffic is in the “Active” state. This state indicates that the firewall is fully functional and can own sessions and set up sessions. An active firewall can be either active-primary or active-secondary, depending on the Device ID and the HA configuration. An active-primary firewall connects to User-ID agents, runs DHCP server and DHCP relay, and matches NAT and PBF rules with the Device ID of the active-primary firewall. An active-secondary firewall connects to User-ID agents, runs DHCP server, and matches NAT and PBF rules with the Device ID of the active-secondary firewall. An active-secondary firewall does not support DHCP relay1. References: HA Firewall States, PCNSE Study Guide (page 53)

• A and D are the best practice deployment modes for the firewall if the company wants to add threat prevention to the network without redesigning the network routing. This is because these modes allow the firewall to act as a transparent device that does not affect the existing network topology or routing1.
• A: VirtualWire mode allows the firewall to be inserted into any existing network segment without changing the IP addressing or routing of that segment2. The firewall inspects traffic between two interfaces that are configured as a pair, called a virtual wire. The firewall applies security policies to the traffic and forwards it to the same interface from which it was received2.
• D: Layer 2 mode allows the firewall to act as a switch that forwards traffic based on MAC addresses3. The firewall inspects traffic between interfaces that are configured as Layer 2 interfaces and belong to the same VLAN. The firewall applies security policies to the traffic and forwards it to the appropriate interface based on the MAC address table3.

Palo Alto Networks Device Telemetry data, collected from firewalls with a device certificate installed, is stored on Palo Alto Networks Update Servers. This telemetry data includes information about threats, device health, and other operational metrics that are crucial for the continuous improvement of security services and threat intelligence. The collected data is anonymized and securely transmitted to Palo Alto Networks, where it is used to enhance the overall effectiveness of threat identification and prevention capabilities across all deployed devices. This collaborative approach helps in keeping the security ecosystem updated and resilient against emerging threats.

The two key exchange algorithms that consume the most resources when decrypting SSL traffic are ECDHE and DHE. These are both Diffie-Hellman based algorithms that enable perfect forward secrecy (PFS), which means that they generate a new and unique session key for each SSL/TLS session, and do not reuse any previous keys. This enhances the security of the encrypted communication, but also increases the computational cost and complexity of the key exchange process. ECDHE stands for Elliptic Curve Diffie-Hellman Ephemeral, which uses elliptic curve cryptography (ECC) to generate the session key. DHE stands for Diffie-Hellman Ephemeral, which uses modular arithmetic to generate the session key. Both ECDHE and DHE require more CPU and memory resources than RSA, which is a non-PFS algorithm that uses public and private keys to encrypt and decrypt the session key123. References: Key Exchange Algorithms, Best Practices for Enabling SSL Decryption, PCNSE Study Guide (page 60)

The Advanced Routing Engine in Palo Alto Networks firewalls enhances the capabilities of routing functionalities, allowing for more complex and robust routing configurations. To enable the Advanced Routing Engine on a Palo Alto Networks firewall, an administrator needs to navigate to the Network tab, select Virtual Routers, and then access the settings for the specific virtual router they wish to configure. Within the Router Settings under the General tab, there's an option to enable Advanced Routing features. After enabling this option, the administrator must commit the changes and perform a system reboot for the changes to take effect. This process allows the firewall to utilize advanced routing protocols and features, enhancing its ability to manage and route traffic more efficiently across different network segments.

Cisco TrustSec technology uses Security Group Tags (SGTs) to enforce access controls on Layer 2 traffic. When implementing Zone Protection on a Palo Alto Networks firewall in an environment with Cisco TrustSec, you should configure Ethernet SGT Protection. This setting ensures that the firewall can recognize SGTs in Ethernet frames and apply the appropriate actions based on the configured policies.The use of Ethernet SGT Protection in conjunction with TrustSec is covered in advanced firewall configuration documentation and in interoperability guides between Palo Alto Networks and Cisco systems.

traffic log would list an application as “not-applicable” if the firewall denied the traffic before the application match could be performed. This can happen if the traffic matches a security rule that is set to deny based on any parameter other than the application, such as source, destination, port, service, etc1. In this case, the firewall does not inspect the application data and discards the traffic, resulting in a “not-applicable” entry in the application field of the traffic log1.

The cause of the unsecured website warnings is that the forward trust certificate has not been signed by the self-signed root CA certificate. The forward trust certificate is used by the firewall to generate a copy of the server certificate for outbound SSL decryption (SSL Forward Proxy). The firewall signs the copy with the forward trust certificate and presents it to the client. The client then verifies the signature using the public key of the CA that issued the forward trust certificate. If the client does not trust the CA, it will display a warning message. Therefore, the forward trust certificate must be signed by a CA that is trusted by the client. In this case, the administrator has installed the self-signed root CA certificate in all client systems, so this CA should be used to sign the forward trust certificate. However, as shown in the screenshot, the forward trust certificate has a different issuer than the self-signed root CA certificate, which means it has not been signed by it. This causes the client to reject the signature and show a warning message. To fix this issue, the administrator should generate a new forward trust certificate and sign it with the self-signed root CA certificate12. References: Keys and Certificates for Decryption Policies, How to Configure SSL Decryption

IP flood thresholds, you can also use DoS Protection profiles to detect and prevent session exhaustion attacks in which a large number of hosts (bots) establish as many sessions as possible to consume a target’s resources. On the profile’s Resources Protection tab, you can set the maximum number of concurrent sessions that the device(s) defined in the DoS Protection policy rule to which you apply the profile can receive. When the number of concurrent sessions reaches its maximum limit, new sessions are dropped. https://docs.paloaltonetworks.com/pan-os/10-1/pan-os-admin/zone-protection-and-dos-protection/zone-defense/dos-protection-profiles-and-policy-rules/dos-protection-profiles.html

Decryption can be resource-intensive, and in scenarios where the firewall is nearing its resource limits, optimizing decryption practices is crucial. One way to do this is by choosing more efficient encryption algorithms that require less computational power.

C. Use ECDSA instead of RSA for traffic that isn't sensitive or high-priority:

• Elliptic Curve Digital Signature Algorithm (ECDSA) is known for requiring smaller key sizes compared to RSA for a comparable level of security. This translates to less computational overhead during the encryption and decryption processes.
• By using ECDSA for traffic that isn't sensitive or high-priority, the administrator can reduce the processing load associated with decryption on the firewall. This is particularly beneficial in scenarios where resource optimization is necessary.
• It's important to note that this approach does not compromise the security of encrypted traffic. Instead, it offers a more resource-efficient way to manage decryption, thus helping to maintain firewall performance even when system resources are under significant demand.

By judiciously applying this strategy, administrators can manage the decryption workload on the firewall, ensuring continued protection and inspection of encrypted traffic without overburdening the firewall's resources.

When the peer device will act as the initiator and none of the peer addresses are known, the administrator can enable Passive Mode to establish the VPN connection. Passive Mode tells the firewall to wait for the peer device to initiate the VPN connection. The other options are incorrect. Option A, setting up certificate authentication, would require the administrator to know the peer device's certificate. Option C, using the Dynamic IP address type, would require the administrator to know the peer device's dynamic IP address. Option D, configuring the peer address as an FQDN, would require the administrator to know the peer device's fully qualified domain name.

The firewalls exchange hello messages and heartbeats at configurable intervals to verify that the peer firewall is responsive and operational. Hello messages are sent from one peer to the other to verify the state of the firewall. The heartbeat is an ICMP ping to the HA peer. A response from the peer indicates that the firewalls are connected and responsive.

When using certificate authentication for firewall administration on Palo Alto Networks devices, the method used for authorization is typically the Local database. Certificate authentication ensures that the entity attempting to access the firewall is in possession of a valid certificate. Once the certificate is validated for authentication, the authorization process determines what level of access or permissions the authenticated entity has. This is usually managed locally on the firewall, where administrators can define roles and permissions associated with different users or certificates. Thus, the authorization process, in this case, leverages the Local database to enforce access controls and permissions, aligning with best practices for secure management of network devices.

In an active/active high availability (HA) firewall pair, when a firewall experiences a failure of a monitored path, it enters the “Tentative” state1. This state indicates that the firewall is synchronizing sessions and configurations from its peer due to a failure or a change in monitored objects such as a link or path. The firewall in this state is not fully functional but is working towards resuming normal operations by syncing with its peer. Therefore, the correct answer is B. Tentative.

Firewall Stuck in Initial (Leaving Suspended State) - Palo Alto Networks

To determine the egress interface a Palo Alto Networks firewall will use to route a specific IP address, the appropriate command is test routing fib-lookup ip 10.2.5.3 virtual-router default. This command performs a Forwarding Information Base (FIB) lookup for the specified IP address within the context of the specified virtual router, which in this case is the default virtual router. The FIB lookup process checks the routing table and the associated forwarding information to determine the next-hop and the egress interface for the given IP address. This command is instrumental for troubleshooting and verifying routing decisions made by the firewall to ensure that traffic is routed as expected through the network infrastructure.

The firewall can use three multi-factor authentication methods to authenticate access to the firewall: SMS, user certificate, and one-time password. These methods can be used in combination with other authentication factors, such as username and password, to provide stronger security for accessing the firewall web interface or CLI. The firewall can integrate with various MFA vendors that support these methods through RADIUS or SAML protocols5. Voice and fingerprint are not supported by the firewall as MFA methods. References: MFA Vendor Support, PCNSE Study Guide (page 48)

To prevent the import from affecting ongoing traffic when you import the configuration of an HA pair into Panorama, you should disable config sync on both firewalls. Config sync is a feature that enables the firewalls in an HA pair to synchronize their configurations and maintain consistency. However, when you import the configuration of an HA pair into Panorama, you want to avoid any changes to the firewall configuration until you verify and commit the imported configuration on Panorama. Therefore, you should disable config sync before importing the configuration, and re-enable it after committing the changes on Panorama12. References: Migrate a Firewall HA Pair to Panorama Management, PCNSE Study Guide (page 50)

These are the two links that can be used to configure an active/active high availability pair. An active/active high availability pair consists of two firewalls that are both active and share the traffic load between them1. To configure an active/active high availability pair, the following links are required2:

• HA1: This is the control link that is used for exchanging heartbeat messages and configuration synchronization between the firewalls. It can be a dedicated interface or a subinterface. It can also have a backup link for redundancy.
• HA2: This is the data link that is used for forwarding sessions from one firewall to another in case of failover or load balancing. It can be a dedicated interface or a subinterface. It can also have a backup link for redundancy.
• HA3: This is the session owner synchronization link that is used for synchronizing session information between the firewalls in different virtual systems. It can be a dedicated interface or a subinterface. It is only required for active/active high availability pairs, not for active/passive pairs.

When deploying a large number of firewalls, such as 15 GlobalProtect gateways around the world, it's crucial to have a scalable configuration approach. Panorama offers several features to help scale configurations efficiently:

B. Template stacks:

• Template stacks in Panorama allow administrators to create a collection of configuration templates that can be applied to multiple firewalls or device groups. This enables the consistent deployment of shared settings (such as network configurations, security profiles, etc.) across all managed firewalls, ensuring uniformity and reducing the effort required to manage individual firewall configurations.

D. Variables:

• Variables in Panorama provide a way to customize template configurations for individual firewalls or device groups without altering the overall template. For example, a variable can be used to define a unique IP address, hostname, or other specific settings within a shared template. When the template is applied, Panorama replaces the variables with the actual values specified for each device or device group, allowing for customization within a standardized framework.

By using template stacks and variables, an administrator can rapidly deploy and manage configurations across multiple GlobalProtect gateways, ensuring consistency while still accommodating site-specific requirements. This approach streamlines the deployment process and enhances the manageability of a widespread GlobalProtect infrastructure.
