Other certification materials providers often include outdated or removed questions by Palo Alto Networks in their PCSFE exam. These outdated questions lead to customers failing their Palo Alto Networks Certified Software Firewall Engineer Exam exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions. Our main priority is your success in the Palo Alto Networks PCSFE exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.

 

Question 1

How are Palo Alto Networks Next-Generation Firewalls (NGFWs) deployed within a Cisco ACI architecture?

Answer Options
Correct Answer: C
Explanation

Palo Alto Networks Next-Generation Firewalls (NGFWs) are deployed within a Cisco ACI architecture using service graphs. Service graphs are logical representations of how traffic flows through different network services, such as firewalls, load balancers, or routers. By configuring service graphs, you can insert NGFWs into the traffic path and apply security policies to the traffic. Reference: [Palo Alto Networks NGFW Integration with Cisco ACI]

Question 2

Which two steps are involved in deployment of a VM-Series firewall on NSX? (Choose two.)

Answer Options
Correct Answer: C, D
Explanation

To deploy a VM-Series firewall on NSX, you need to enable communication between Panorama and the NSX Manager. This allows Panorama to receive information about the virtual machines and services in the NSX environment. You also need to register the VM-Series firewall as a service on the NSX Manager.This allows NSX to redirect traffic to the VM-Series firewall for inspection3.

Question 3

Which component scans for threats in allowed traffic?

Answer Options
Correct Answer: C
Explanation

Security profiles are the components that scan for threats in allowed traffic. Security profiles are sets of rules or settings that define how the firewall will inspect and handle traffic based on various threat prevention technologies, such as antivirus, anti-spyware, vulnerability protection, URL filtering, file blocking, data filtering, and WildFire analysis. Security profiles can be applied to Security policy rules to enforce granular protection against known and unknown threats in allowed traffic. Intelligent Traffic Offload, TLS decryption, and NAT are not components that scan for threats in allowed traffic, but they are related features that can enhance security and performance.

Question 4

Which two actions can be performed for VM-Series firewall licensing by an orchestration system? (Choose two.)

Answer Options
Correct Answer: A, C
Explanation

The two actions that can be performed for VM-Series firewall licensing by an orchestration system are:

Creating a license

Registering an authorization code

An orchestration system is a software tool that automates and coordinates complex tasks across multiple devices or platforms. An orchestration system can perform various actions for VM-Series firewall licensing by using the Palo Alto Networks Licensing API. The Licensing API is a RESTful API that allows programmatic control of license management for VM-Series firewalls. Creating a license is an action that can be performed for VM-Series firewall licensing by an orchestration system using the Licensing API. Creating a license involves generating a license key for a VM-Series firewall based on its CPU ID and the license type. Registering an authorization code is an action that can be performed for VM-Series firewall licensing by an orchestration system using the Licensing API. Registering an authorization code involves activating a license entitlement for a VM-Series firewall based on its authorization code and CPU ID. Renewing a license and downloading a content update are not actions that can be performed for VM-Series firewall licensing by an orchestration system using the Licensing API, but they are related tasks that can be done manually or through other methods.

Question 5

Which two mechanisms could trigger a high availability (HA) failover event? (Choose two.)

Answer Options
Correct Answer: A, D
Explanation

Heartbeat polling and link monitoring are two mechanisms that can trigger an HA failover event. Heartbeat polling is a method of verifying the health of the peer firewall by sending periodic heartbeat messages. If the heartbeat messages are not received within a specified interval, the firewall assumes that the peer is down and initiates a failover. Link monitoring is a method of verifying the connectivity of the interfaces on the firewall by sending link state packets. If the link state packets are not received on a specified number of interfaces, the firewall assumes that the network is down and initiates a failover. Ping monitoring and session polling are not HA mechanisms, but they are used for path monitoring and session synchronization respectively.
