IP: 10.0.0.60Int VLAN10
SM: 255.255.255.0IP address 10.0.0.1/28
GW: 10.0.0.1Speed 100 Duplex Full
A.
Change the duplex on the switch interface to half
B.
Change the speed on the switch interface to 10Mbps
C.
Change the subnet mask of the computer to 255.255.255.240
D.
Change the IP address of the computer to 10.0.0.12
Explanation:
Admin: Please fix. The correct answer is C.
Information given is that the network is in a /28 and it the computer interface is configured as a /24…
Although the subnet mask in the questions is listed incorrectly; it should be 255.255.255.240. The IP of the subnet is also listed incorrectly; it should be
10.0.0.0
But since the CIDR is /28 that gives us a block size of 16
first network .0 / next network is .16 / third network is .32 etc. etc.
So the correct answer is still D: Change the IP address of the computer to 10.0.0.12
because it’s still within the subnet of the GW (gateway)ip of 10.0.0.1.
