A network administrator is connecting hosts A and B directly through their Ethernet interfaces, as shown in the illustration. Ping attempts between the hosts are unsuccessful. What can be done to provide connectivity between the hosts?1. A crossover cable should be used in place of the straight-through cable.2. A rollover cable should be used in place of the straight-through cable.3. The subnet masks should be set to 255.255.255.192.4. A default gateway needs to be set on each host.5. The subnet masks should be set to 255.255.255.0.
