Refer to the exhibit. An engineer is updating the R1 configuration to connect a new server to the management network. The PCs on the management network must be blocked from pinging the default gateway of the new server. Which command must be configured on R1 to complete the task?
To prevent the PCs on the management network from pinging the default gateway of the new server, a host route can be configured. The command `R1(config)#ip route 172.16.2.2 255.255.255.255 gi0/0` specifies a route to the new server's address via the specified interface. This ensures that only traffic specifically destined for the new server (172.16.2.2) will be routed appropriately, while it won't allow direct pings to the gateway. Consequently, this will block the PCs from pinging the default gateway of the new server.
The fact that you specify a host route is the reason you cannot ping any other host than the server in that subnet. Not that you specified the egress interface instead of the next hop address. I tried both scenarios in PT with a host route and they give exactly the same result, as to be expected.
While C is the right answer wouldn't the ideal configuration be ip route 172.16.2.2 255.255.255.255? C is the right answer because it is a /32 host route so as long as the 172 number isn't advertised by OSPF or configured statically packets from R1 can not reach the 172 gateway.
You right my friend
Please correct me if I'm wrong. I understand that we need to block the ping to the default gateway of the new server. In this case, it is 172.16.2.1. To achieve this, we should configure a static route specifically for the new server so that it cannot be pinged from the default gateway.
"Refer to the exhibit. An engineer is updating the R1 configuration to connect a new server to the management network. The PCs on the management network must be blocked from pinging the default gateway of the new server. Which command must be configured on R1 to complete the task?" Ummm...Im not seeing how any answer blocks anything. perhaps ip route 172.16.2.2 255.255.255.255 127.0.0.1 ? or better yet make an ACL.
C is correct
Excuse my ignorance, however I believe you're all wrong. The question asks you to enter a command to block PC1 and PC2 from pinging the default gateway of the new server. A default gateway appears on a router interface. As such, the default gateway of the new server (at 172.16.2.2) is 172.16.2.10 (R2's Gi 0/0). Now, we have a new question to the one you've been answering!
You might be overthinking it a little bit junior. Just go with the flow and pick that host route in answer "C"
C is is a give way price, 172.16.2.2 255.255.255.255 192.168.1.15 its not on the answers but its another way to do it on PT
I don't see this in the diagram: "An engineer blocking from pinging the default gateway."
