Exam 200-301 topic 1 question 462 discussion

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.

None of the option is correct. A & C are correct command to set static route for new server. However it does not meet requirement to block PCs to ping to New Server. For that access list should be configured on interface

The correct command is: ip route 172.16.2.2 255.255.255.255 gi0/0 Here’s what this means in plain English: ip route: This tells the router you're adding a new route. 172.16.2.2: This is the destination (the specific server you want the PCs to reach). 255.255.255.255: This is a host-specific route. It means the route is for exactly this one IP address (172.16.2.2) and nothing else. gi0/0: This is the interface (on R1) that connects to R2. Traffic to the server (172.16.2.2) will be sent out through this interface

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.

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!

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."
