An administrator is troubleshooting a Layer 3 communication issue between the web server and the database server. The administrator finds the following information. Which of the following corrects the communication issue?

While modifying the firewall's subnet could potentially affect traffic flow, it does not directly resolve the issue between the web server and the database server. The firewall's configuration is important, but the primary problem lies with the database server's subnet settings.

Adjusting the default gateway may help in routing traffic outside the local network, but if the subnet is incorrect, the database server will still be unable to communicate with the web server. The default gateway setting alone cannot correct Layer 3 issues arising from subnet misconfiguration.

While this change might assign a valid IP address, if the subnet mask remains incompatible with the web server's settings, communication will still fail. The specific IP address is less crucial than ensuring a matching subnet for effective communication.

Updating the firewall's gateway may impact traffic routing, but it does not address the core issue of the database server's subnet configuration. Without the correct subnet settings, the web server will remain unable to communicate with the database server.
