The top questions for the interview
Here, we’ve provided the top questions for the interview to help you get through any discussion related to Palo Alto, whether you’re new or an expert with years of experience.
We live in a digitalization time that sees computers, the internet, and other electronic gadgets, as well as software applications, have a significant role to play in our lives. Hospitals, banks, financial institutions, government agencies, and manufacturing firms all rely on connected devices for their daily operations.
Unauthorized access or disclosure of certain information, like financial information, intellectual property, and personal data, could lead to grave consequences. Threat actors and intruders can use this information to gain access to these data for various reasons, including profit, extortion, the benefit of societal or political power or even devastation. Therefore, it is essential to establish a comprehensive security policy in place to safeguard sensitive information from high-profile security incidents.

Palo Alto Interview Questions for Freshers
Using the switch SPAN or tap port, users can observe traffic flow across the network. This deployment option allows businesses to closely check the traffic flowing through their networks or servers without needing any changes to their network infrastructure.
It is crucial to set up the proper SPAN origin and SPAN port to destination and activate Tap mode in the Firewall when configuring SPAN. While tap mode allows for an overview of the application, user and contents, we need to be aware that the Firewall cannot control the traffic when it is in this mode since there are no security rules that can be implemented. Tap mode provides access to your Dashboard’s ACC tab. The problem is that the interface must be assigned to an area of security.
Virtual Deployment option:
The Firewall is deployed at a low level on every network segment using this deployment method, which integrates two interfaces. Engineers can monitor and control traffic flow through the link using V-Wire deployment options that overcome the limitations of TAP deployment in mode. App-ID, User-IDand, Content-ID and NAT, and decryption are available through V-Wire. Virtual Wire interface.
Layer 2 deployment option:
Multiple networking interfaces are turned into a “virtual switch” or VLAN mode in Layer 2. The Firewall is configured to Layer two configuration mode, which allows it to change between two or more networks. The flow of traffic through the Firewall is scrutinized according to the policies, improving security and visibility in the network.
The firewall interfaces can be configured to support Access or Trunk Links in this manner; however, they are not included in the Spanning Tree topology. Any BPDUs received through the firewall interfaces will be routed to the Firewall without being routed to the adjacent Layer 2 switch. A default Gateway is typically a Layer 3 switch which supports Inter VLAN routing, a Firewall Security Appliance or a Router-on-a-Stick model, which can transfer traffic across VLAN networks or any other networks.
Layer 3 deployment option:
The Palo Alto firewall routes allow traffic to flow between different interfaces of these layer three deployments. The IP address needs to be added to every connection by the client.
The Layer 3 deployment is the typical configuration. The Firewall controls traffic across multiple interfaces in this mode, each with an IP address of its own and a security zone. The Firewall interfaces can be set up to obtain a lesson through a DHCP server and utilized to manage the security device.
The image above illustrates the standard Layer 3 deployment in which the Firewall controls and routes traffic across three IP networks. Every traffic stream that goes via the Firewall is scrutinized and approved or denied according to the security policies that are in place, similar to previous configuration methods.
Does the security in Palo Alto stateful?
Yes, since the Palo Alto system can process every Firewall’s traffic, it is compared to the session. Additionally, every session must be evaluated to a security policy established in the Firewall.
Virtual routers:
Virtual routers are Layer 3 routers integrated inside the Firewall. The Firewall can use virtual routers to establish access to other subnets. You can create static routes manually or be a part of some or all Layer three routing protocols.
There is also the option of creating multiple VRs, each with its own set of routes which do not share among them. This lets you set different routing behavior for other interfaces.
Multiple VSYS can be connected to the same VR, and multiple VSYS may be equipped with various VRs.
What’s the point that Palo Alto has in Auto Focus?
Palo Alto Auto Focus is a Palo Alto service that may detect major threats and respond effectively without requiring additional resources. The service is a cloud-based threat intelligence system.
WildFireTM, the PAN-DB URL Filtering database Unit 42 and other third-party feeds are all utilized in AutoFocus (including closed-source and free-source information). AutoFocus makes the data searchable and adds data highlighting the prevalence of malware and uncovering malware-related links.
What are the various failover scenarios?
This is known as a failure when one Firewall fails, and the peer assumes the task of protecting traffic. If a monitored metric of the Firewall of the HA pair is in error, for instance, it is triggered by a failover.
The possible explanations for the failure to trigger can be described in the following:
Heartbeat polling and hello messages
Firewalls use heartbeats and Hello messages to ensure that the Firewall on the other side is functioning and responsive. To confirm the functioning of the Firewall, hello messages are transmitted by one party to the next during the configured Hello Interval.
It is an ICMP signal sent over an HA control connection, and the peer replies to confirm that the firewalls are active and connected. The interval between heartbeats is set to 1000 milliseconds. Each time a signal is issued. If three consecutive heartbeat losses occur, the system will failover.
