Question 8

The router interface is a broadcast address.

The router interface configured as 10.0.0.250/24 is indeed a broadcast address for that subnet, which is 10.0.0.0/24. This means that packets sent to this address will not be routed as intended, leading to the issue where it cannot communicate with the web server.

A) The web server is in a different subnet.

This option is incorrect because the web server's IP address, 10.0.0.0/20, is within the broader range that includes the router's subnet of 10.0.0.250/24. The web server is not in a different subnet; both addresses can communicate under the correct circumstances.

B) The router interface is a broadcast address.

This option is correct. The address 10.0.0.250/24 is the last usable address in the subnet 10.0.0.0/24, which identifies it as the broadcast address for that subnet. As a result, the router will not route traffic properly when using this address.

C) The IP address space is a class A network.

This option is misleading. While the IP address 10.0.0.250 does belong to a Class A network, this information does not explain the routing issue. The classification of the network does not directly impact the functionality of routing in this scenario.

D) The subnet is in a private address space.

This statement is true but irrelevant to the issue at hand. The address 10.0.0.0/20 is indeed in a private address space, but this does not explain why packets are not being routed to the web server. The problem lies specifically in the use of the broadcast address.

Conclusion

The issue of the router not routing packets is directly due to the configuration of the router interface as a broadcast address. While the other options present truths about the address space, they do not address the core issue of routing failure. Therefore, Option B is the definitive explanation for the problem encountered.
