Okay, let me see if I've got this right. If the firewall is Layer 2 and connected to switches, we can use staff-sharing. But if it's Layer 3 and connected to routers, no load-sharing groups. Sounds like a recipe for some serious network admin headaches!
Haha, primary/standby networking? Sounds like something straight out of a tech support manual. I wonder if the exam writers were having a bit of fun with that one.
I think the key is the layering and connectivity. If it's Layer 3 to the routers, you can't use load-sharing groups. But the Layer 2 cases seem a bit tricky.
D) The firewall service interface works under the networking condition of Layer 3, uplink and downlink connecting routers You cannot use load-sharing groups.
C) The firewall service interface works in the case of three-layer, uplink and downlink connection to the router You can use primary/standby networking.
B) Under the condition that the firewall service interface works at Layer 2 and connects the switch upstream and downstream Support staff sharing networking
A) Under the condition that the firewall service interface works at Layer 2 and connects the router upstream and downstream It is recommended to use a staff-sharing network.
Wait, so the firewall service interface can work at Layer 2 and connect to the router or switch? That's interesting, but I'm not sure about the staff-sharing part.
