Arrange the steps in the correct order to enable and test ICMP ping responses on a Palo Alto Networks firewall Layer 3 interface, starting with profile configuration.

### The order 1. **Configure the Layer 3 interfaces with their network addresses**: routing and zone mapping require the relevant interfaces to exist as configured network interfaces. 2. **Add the interfaces and default route to the virtual router**: the firewall needs its routing context and Internet next hop. 3. **Create zones and map interfaces to them**: zones provide interface groupings for security-policy decisions. 4. **Create and assign the Allow-ping interface-management profile, then commit**: this permits the selected interface service and applies the changes. 5. **Test reachability to firewall interfaces from the hosts**: testing follows configuration and commit. ### Terms - **Layer 3**: The network layer where IP routing occurs. ### Remember Configure interfaces and routing before testing the committed management access.
