What should be checked if users on a LAN can’t access a company web server?

• A. Ensure there is sufficient bandwidth available
• B. Verify that the static route to the server is present in the routing table
• C. Check the DHCP leases for the users
• D. Confirm that DNS settings are configured correctly

Answer: (B)

Verifying that the static route to the server is present in the routing table is crucial when users on a LAN are unable to access a company web server. A static route determines how traffic is directed between different networks. If a static route to the web server is missing or incorrectly configured, packets may not reach the server, resulting in connectivity issues for users attempting to access the web application. This step is particularly important in a segmented network where the server may reside on a different subnet. While checking bandwidth, DHCP leases, and DNS settings are helpful troubleshooting steps, they do not address the most direct aspect of network routing that could prevent access to the server. Bandwidth issues typically result in slow connectivity rather than complete inaccessibility. Verifying DHCP leases is important to ensure that devices are obtaining valid IP addresses but does not resolve routing issues directly. Confirming DNS settings is also pertinent, as incorrect settings can prevent name resolution, but if the route to the server is absent, DNS resolution would be irrelevant. Thus, ensuring the static route is present in the routing table directly targets the routing layer, which is essential for the communication between users and the web server.
