Palo Alto is an American multinational cybersecurity company located in California. The core products of Palo Alto included are advanced firewalls and cloud-based applications to offer an effective security system to any enterprice. Palo Alto is a popular cybersecurity management system which is mainly used to protect networking applications. For the beginners or experienced, our trainee experts crafted the top interview questions that will help to crack any complex interview process related to the palo alto.

1. Is Palo Alto a stateful firewall?

Ans: The answer would be yes because here all the firewall traffic can be transmitted through the Palo Alto system, and later these are matches against a session. More importantly, each session should match against a firewall cybersecurity policy as well.

2. What is the purpose of Palo Alto Focus?

Ans: Palo Alto Focus is one of the services available in Palo Alto to identify the critical attacks and take necessary action without using any additional resources. It is considered as the cloud-based threat intelligence service.

3. Name the types of deployment modes in Palo Alto?

Ans: There are four deployment models available such as;

  1. Tap mode: this mode allows users to monitor any type of traffic flow across the networking system with the help of tap or switch SPAN/mirror port.
  2. Virtual wire: in this deployment model, the firewall system is installed passively on any network segment by combing two interfaces together.
  3. Layer 2 mode: in this layer mode, multiple networking interfaces will be configured into a “virtual-switch” or VLAN mode.
  4. Layer 3 deployment: In this layer 3 deployments, the Palo Alto firewall routes allow traffic between multiple interfaces. User should add the IP address to each interface.
4. What are the scenarios for failover triggering?

Ans: The following are the scenarios that explain the failure over triggering,

Failure occurs, if one or more monitored interface fail

Failure occurs, if one or more specified destinations cannot be pinged by the active firewall

If the active device does not respond to heartbeat polls or loss of three consecutive heartbeats over a period of 1000 millisecond this time failure occurs.

5. Which command is used to check the firewall policy matching in Palo Alto?

Ans: Open the Palo Alto web browser -> go to test security -> policy -> match from trust to untrust destination .

6. What is the application command center (ACC)?

Ans: The application command center offers visibility to the traffic patterns and actionable information on threats in the firewall network logs.

7. What is the purpose of Palo Alto’s autofocus?

Ans: Autofocus in Palo Alto is the kind of threat intelligence service; this supports easier identification of critical attacks so that effective action can be taken without the need for the additional resources.

8. What is the zone protection profile?

Ans: With the help of the Zone protection profile, you will get complete protection from attacks like floods, reconnaissance, and packet-based attacks. The flood attacks can be of type SYN, ICMP, and UDP, etc. The reconnaissance protections will help you to defend against port and host sweeps. The packet protections help you to get the protection from the large ICMP and ICMP fragment attacks.
