An administrator configures three subnets to the corporate network. All servers should communicate with the main corporate network and access the internet. The administrator creates the following…

Removing specific routes would hinder communication, not enable it, and the goal is to enable communication for all servers.

The problem states multiple subnets need to communicate with the 'main corporate network,' implying a broader network range than a single subnet. By replacing the destination 192.168.1.0/24 with 192.168.0.0/24, the routing table establishes a route to the entire 192.168.0.0/24 network, which is a common CIDR block encompassing multiple subnets within a corporate network, thus enabling communication for all relevant subnets in one step.

Adding a source and destination route for 192.168.0.0/24 might be partially correct, but replacing an existing, overly specific route is a more precise 'one step' fix for a misconfiguration, assuming a specific route already exists.

Reconfiguring Network 4 to a different IP range does not address routing table issues for existing subnets to communicate with the main corporate network or the internet; it changes a network's identity, which is not the core problem.
