PSE-SoftwareFirewall Dumps with Practice Exam Questions Answers

In AWS, VM-Series firewalls support only active-passive high availability (HA) configuration. This means that one firewall is active and processing traffic, while the other remains passive and takes over in the event of a failure. This design consideration ensures continuous availability and reliability of firewall services in the AWS environment.

For deploying VM-Series firewalls in high availability (HA), it is crucial to ensure that both firewalls in the HA pair have identical licenses and subscriptions to ensure feature parity and uninterrupted service during failover. Additionally, both firewalls must be deployed on the same type of hypervisor to ensure compatibility and proper synchronization of state and configurations between the active and passive units.

Full set of APIs enabling programmatic control of policy and configuration:

Palo Alto Networks provides a comprehensive set of APIs that allow for the automation and orchestration of security policies and configurations in an SDN environment.

To avoid split brain scenarios in an active-passive high availability (HA) pair deployment, the management interface can be used as the HA1 backup link. This ensures reliable communication between the HA pair and prevents both firewalls from assuming the active role simultaneously, which can happen if they lose connectivity with each other on the primary HA1 link.

Best Practices for HA Configuration: Avoiding Split Brain

Zero Trust implementation revolves around the principle that no entity, inside or outside the network, should be trusted by default. The primary methods that benefit an organization are:

Security automation is seamlessly integrated: Zero Trust requires continuous monitoring and verification of every device and user attempting to access resources. Automation helps in efficiently managing these processes, ensuring that security policies are consistently enforced without human error. Automated tools can quickly detect anomalies, respond to threats, and update access controls dynamically.
