You added a route on the Firebox for the 10.0.20.0/24 network. The server has 10.0.2.1 configured as its default gateway. The clients have 10.0.10.1 configured as their default gateway. The client computers on the
10.0.10.0/24 network cannot route traffic to the server at 10.0.20.100. What could cause this problem? (Select one.)
10.0.10.0/24 network cannot route traffic to the server at 10.0.20.100. What could cause this problem? (Select one.)
Suggested Answer: C Vote an answer
In this scenario:
* The Firebox has a route to the 10.0.20.0/24 network.
* The server has 10.0.2.1 as its default gateway.
* Clients on the 10.0.10.0/24 network use 10.0.10.1 as their default gateway.
The issue arises because the server is in the 10.0.20.0/24 network and should have a gateway that directs traffic through the appropriate path. However, since 10.0.2.1 is configured as the server's gateway, the server likely doesn't have a correct return path to the clients on 10.0.10.0/24. This misconfiguration prevents the server from properly routing responses back to clients.
* Option Cis correct because the misconfigured default gateway on the server disrupts the routing, preventing communication with clients.
* Option Ais incorrect because the router at 10.0.2.254 is used for routing but doesn't need additional configuration if the server's gateway is corrected.
* Option Bis incorrect because the clients have the correct gateway for reaching the Firebox.
* Option Dis irrelevant since adding an IP in 10.0.10.0/24 on the router won't resolve the routing issue.
* Option Eis incorrect because adding a route on the server wouldn't solve the default gateway misconfiguration.
