For a network security administrator to authenticate and identify a user with a new BYOD-type device that is not joined to the corporate domain, the most effective method is to use an Authentication policy targeting users not yet identified by the system.

A. an Authentication policy with 'unknown' selected in the Source User field:

An Authentication policy allows the firewall to challenge unidentified users for credentials. By selecting 'unknown' in the Source User field, the policy targets users who have not yet been identified by the firewall, which would include users on new BYOD devices not joined to the domain.

Once the user provides valid credentials, the firewall can authenticate the user and map their identity to subsequent sessions, enabling the application of user-based policy rules and monitoring.

This approach ensures that new and unknown devices can be properly authenticated and identified without compromising security or requiring the device to be part of the corporate domain.

For virtual systems (vSys) on a Palo Alto Networks firewall to communicate with each other, especially when separate virtual routers (VRs) are used for each vSys, the configuration must facilitate proper routing and security policy enforcement. The key aspects to focus on include:

A. External zones with the virtual systems added:

External zones are special types of zones that are used to facilitate traffic flow between virtual systems within the same physical firewall. By adding virtual systems to an external zone, you enable them to communicate with each other, effectively bypassing the need for traffic to exit and re-enter the firewall.

D. Add a route with next hop next-vr by using the VR configured in the virtual system:

When using separate VRs for each vSys, it's essential to configure inter-VR routing. This is done by adding routes in each VR with the next hop set to 'next-vr', specifying the VR of the destination vSys. This setup enables traffic to be routed from one virtual system's VR to another, facilitating communication between them.

E. Ensure the virtual systems are visible to one another:

Visibility between virtual systems is a prerequisite for inter-vSys communication. This involves configuring the virtual systems in a way that they are aware of each other's existence. This is typically managed in the vSys settings, where you can specify which virtual systems can communicate with each other.

By focusing on these configuration details, the network security engineer can ensure that the virtual systems can communicate effectively, maintaining the necessary isolation while allowing the required traffic flow.
