After performing routine maintenance, an administrator notices that clients in the 192.168.4.0/24 subnet can no longer reach the corporate website hosted on the 192.168.2.0/24 subnet. The clients can access other local resources and the default gateway responds to pings. What is the MOST likely reason that the clients cannot access the corporate website?
The corporate website's server has a misconfigured gateway preventing responses to the clients.
The switch VLAN configuration has been reset, causing the clients to be on the wrong VLAN.
A route to the 192.168.2.0/24 subnet is missing from the router's routing table after the maintenance.
The subnet mask on the clients has been incorrectly set, preventing communication with the corporate website subnet.
