Workstation A has been assigned an IP address of 192.0.2.24/28. Workstation B has been assigned an IP address of 192.0.2.100/28. The two workstations are connected with a straight-through cable. Attempts to ping between the hosts are unsuccessful. What two things can be done to allow communications between the hosts? (Choose two)

A. Replace the straight-through cable with a crossover cable.

B. Change the subnet mask of the hosts to /25.

C. Change the subnet mask of the hosts to /26.

D. Change the address of Workstation A to 192.0.2.15.

E. Change the address of Workstation B to 192.0.2.111.






 

Suggested Answer: AB

To specify when we use crossover cable or straight-through cable, we should remember:
Group 1: Router, Host, Server -
Group 2: Hub, Switch -
One device in group 1 + One device in group 2: use straight-through cable
Two devices in the same group: use crossover cable
-> To connect two hosts we must use crossover cable -> A is correct.
With the subnet mask of /28, 192.0.2.24 & 192.0.2.100 will be in different subnets (192.0.2.24 belongs to subnet 192.0.2.16/28; 192.0.2.100 belongs to subnet
192.0.2.96). To make them in the same subnet we need more space for host. Because 100 < 128 so we the suitable subnet should be /25.
