What are two valid zone types that can be selected from the zone configuration menu, per Palo Alto Networks best practices? (Choose two answers)
In the Palo Alto Networks PAN-OS environment, a Security Zone is a logical grouping of interfaces that allows for the application of security policies based on the network's topology and security requirements. When navigating to the zone configuration menu, an administrator must define the Type of the zone, which dictates how the firewall processes traffic and which types of interfaces can be associated with it.
The primary valid zone types available in the configuration menu include Layer 3, Layer 2, Virtual Wire, Tap, and Tunnel.
Layer 3 (Option A): This is the most common zone type. It is used when the firewall acts as a routing hop. Interfaces in a Layer 3 zone have IP addresses assigned and participate in routing tables.
Layer 2 (Option B): This type is used when the firewall is integrated into a switched environment where it performs inspection without acting as a router. Traffic is switched between interfaces within the same Layer 2 zone based on MAC addresses.
It is important to note that while Management and DMZ are common terms in networking, they are not technical 'types' in the zone configuration menu. 'Management' refers to a dedicated physical port for administrative access (which typically does not belong to a security zone for transit traffic), and 'DMZ' is a functional role or name given to a zone (usually of the Layer 3 type) rather than a selectable architectural type.
