Workstation A has been assigned an IP address of Workstation B has been assigned an IP address of 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)

  • E. Change the address of Workstation B to
Answer: Option A. B.

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, & will be in different subnets ( belongs to subnet; belongs to subnet To make them in the same subnet we need more space for host. Because 100 < 128 so we the suitable subnet should be /25.
