- Interface Fa0/0 is missing IP address configuration information.
- IP addresses on the subinterfaces are incorrectly matched to the VLANs.
- Each subinterface of Fa0/0 needs separate no shutdown commands.
- Routers do not support 802.1Q encapsulation on subinterfaces.
Answers Explanation & Hints: Since Host 1 (in VLAN 20) has the IP 172.18.1.10/27, the subinterface Fa0/0.1 should be configured with an IP address in the network 172.168.1.0/27. Similarly, Fa0/0.2 should be with an IP address in the network 172.168.1.64/27 and Fa0/0.3 should be with an IP address in the network 172.168.1.96/27.
