Palo Alto Networks (PANW) System Engineer (PSE) Practice Exam

What allows you to create a policy that automatically adapts to instance additions, moves, or deletions?

1. XML APIs

2. Device Groups

3. Ansible

4. Dynamic Address Groups

The correct answer is: Dynamic Address Groups

Dynamic Address Groups are a powerful feature in Palo Alto Networks' firewall architecture that allows for the creation of policies that automatically adapt to changes in the network environment, such as the addition, movement, or deletion of instances. This capability is achieved by leveraging specific attributes of the endpoints to define these groups dynamically. Instead of having to manually update policies whenever there are changes in the network—like new devices being added or existing ones being moved—Dynamic Address Groups dynamically assess and group instances based on defined criteria. For example, you can create a Dynamic Address Group based on tags, IP addresses, or other attributes. As devices meet or no longer meet these criteria, they are automatically added to or removed from the group. This ensures that security policies remain relevant and effective without requiring constant manual intervention. Using Dynamic Address Groups streamlines policy management in dynamic environments, such as cloud infrastructures where instances frequently change, thereby enhancing the agility and responsiveness of the security posture.
