Designing a ZPF requires several steps. Which step involves defining boundaries where traffic is subjected to policy restrictions as it crosses to another region of the network?

• determine the zones
• design the physical infrastructure
• identify subsets within zones and merge traffic requirements
• establish policies between zones

Explanation: Designing ZPFs involves several steps:

• Step 1. Determine the zones – The administrator focuses on the separation of the network into zones. Zones establish the security borders of a network.
• Step 2. Establish policies between zones – For each pair of \”source-destination\” zones, define the sessions that clients in the source zones can request from servers in destination zones.
• Step 3. Design the physical infrastructure – After the zones have been identified, and the traffic requirements between them documented, the administrator must design the physical infrastructure. This includes dictating the number of devices between most-secure and least-secure zones and determining redundant devices.
• Step 4. Identify subsets within zones and merge traffic requirements – For each firewall device in the design, the administrator must identify zone subsets that are connected to its interfaces and merge the traffic requirements for those zones.
