The payroll department is having issues accessing the company server, DC1 in the server farm subnet, when sending pings, no replies are received from DC1. The two subnets are connected by a fully configured router and only use static IP settings.
DC1: IP address 172.30.1.34, SM 255.255.255.224, Gateway 172.30.1.33, DNS 172.30.1.90.
Payroll: Network ID 172.30.1.0, SM 255.255.255.224, Gateway 172.30.1.1 DNS 172.30.1.90
Based on the information provide above, what is most likely the cause of the problem?
There is an issue with the gateway addresses, they need to be the same for both subnets
There is an issue with the DNS entries, they need to be different for both subnets
The subnet masks need to use the same bits for both subnets
The problem could be caused by an ACL on the router
There is a network overlap with the two network IDs preventing the router from forwarding messages to DC1. A new VLSM Addressing Scheme is advised for the entire network.
