Palo Alto Networks Systems Engineer (PSE): Software Firewall Professional PSE-SoftwareFirewall Exam Practice Test

Answer : B

Data-plane vCPU Licensing:

The CN-Series firewalls are licensed based on the number of data-plane vCPUs. This licensing model reflects the processing power dedicated to handling traffic and security enforcement within the containerized environment.

Answer : A

Geneve (Generic Network Virtualization Encapsulation) is the protocol used for communication between VM-Series firewalls and a Gateway Load Balancer (GWLB) in AWS. Geneve provides a flexible encapsulation method and is specifically supported for integrating with AWS GWLB to ensure seamless traffic flow and security inspection.

Answer : A

Microsegmentation is a security technique that enables granular control of east-west traffic within a software-defined network. By dividing the network into smaller segments, each with its own security policies, microsegmentation allows for detailed control over communication between workloads, thereby reducing the attack surface and preventing lateral movement of threats within the network.

Answer : B, D

The VM-Series firewalls support various dynamic routing protocols to ensure efficient and resilient network traffic management. Among these, OSPF (Open Shortest Path First) and BGP (Border Gateway Protocol) are supported. OSPF is used for intra-domain routing, while BGP is essential for inter-domain routing, allowing VM-Series to participate in complex and scalable network topologies.

Answer : B

Creating a New Virtual Switch:

By creating a new virtual switch, you can segment the network within the ESXi environment. The VM-Series firewall can then be used to provide security controls between these virtual switches using virtual wire mode.

Moving Guests to New Virtual Switch:

Guests requiring additional security are moved to the new virtual switch, allowing the VM-Series firewall to inspect and control traffic between the switches. This setup does not necessitate changes to the existing IP addresses or default gateways of the VMs.

Answer : D

YAML File Structure:

The structure of a YAML file repository for managing configurations typically follows the order of Kubernetes/Deployment_Type/Environment. This hierarchy ensures that the configurations are organized logically, with Kubernetes-specific settings at the top level, followed by the type of deployment, and then the specific environment.
