The correct answer is D. Change the IP address of the computer to 10.0.0.12. The switch VLAN 10 interface is configured as 10.0.0.1/28. A /28 subnet mask equals 255.255.255.240, giving a valid host range of 10.0.0.1 through 10.0.0.14 (broadcast 10.0.0.15). Ann's computer has IP 10.0.0.60, which falls in a completely different /28 block and is…

Explanation
The switch VLAN 10 interface is configured as 10.0.0.1/28. A /28 subnet mask equals 255.255.255.240, giving a valid host range of 10.0.0.1 through 10.0.0.14 (broadcast 10.0.0.15). Ann's computer has IP 10.0.0.60, which falls in a completely different /28 block and is unreachable from the switch's VLAN 10 interface. Changing the IP to 10.0.0.12 places Ann's computer within the valid host range of the switch's subnet (10.0.0.1–10.0.0.14), allowing communication. Option C (changing the subnet mask to 255.255.255.240) would correct the mask but still leave the IP at 10.0.0.60, which is outside the valid range - so the IP must be fixed first. Changing duplex or speed would not resolve a subnet mismatch.
