CompTIA A+ 220-901 – Q515

A customer is having a problem with a newly installed home network. Three computers and a cable modern are connected into a SOHO router with Cat 5e cables. Computer 1 is able to access the Internet; however, Computer 2 and Computer 3 have no Internet access. A technician runs the ipconfig command on Computer 1:
Computer 1:
IPv4 address: 192.168.1.100
Subnet Mask: 255.255.255.0
Gateway: 193.134.4.1
The technician then runs the ipconfig command on two other computers that are NOT able to access the Internet:
Computer 2:
IPv4 address: 192.168.1.101
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.1
Computer 3:
IPv4 address: 192.168.1.102
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.1
Which of the following is the MOST likely reason Computer 2 and Computer 3 cannot access the Internet?

A. The DHCP client service is disabled on Computer 2 and Computer 3. The service should be enabled to receive the correct network settings.
B. The subnet masks are misconfigured on Computer 2 and Computer 3. The subnet mask on both computers should be set to 255.255.252.0.
C. The gateways are misconfigured on Computer 2 and Computer 3. The gateways on both computers should be set to 193.134.4.1
D. Computer 2 and Computer 3 are not receiving a response from the router’s DHCP service. The technician should enable DHCP.

Correct Answer: C
