Refer to the Exhibit. Hosts on VLAN 200 can ping each other. Hosts on VLAN 100 however, are unable to communicate with each other. All hosts on each VLANs are configured with correct IP addresses. It also required that hosts on different VLANs should be able to communicate with each other but they cannot. How can the network administrator solve this problem? (Choose four)

Change the IP address of PC3 and PC4 with 172.16.100.1 and 172.16.100.2 respectively

On the switch, reconfigure the misconfigured interface to the correct VLAN

Configure the interface Fa0/24 of the switch as trunk port

Add and connect another switch using crossover cable and configure it as trunk

Add a Router and connect to the switch using straight-through cable to the switchês port Fa0/24

Implement an Inter-VLAN routing using sub-interfaces with 802.1Q encapsulation

Explanation

First, as you can see from the figure, Interface Fa0/3 resides on the wrong VLAN. Use the command switchport access vlan 100 on the switchês Fa0/3 interface. To enable routing between VLANs, add a router and implement Inter-VLAN. Use the IEEE standard 802.1Q or Cisco Proprietary Standard ISL as the encapsulation method. In this case, connect the router on any of the switchês port excluding the ports Fa0/1-4 (These are configured as Access Ports). Finally, you must configure the interface on the switch where the router is connected (Fa0/24 in this case) as trunk.
