The Fa0/1 port is not operational on one of the switches.
The Link connecting the switches has not been configured as a trunk.
At lease one port needs to be configured in VLAN 1 for VLANs 10 and 15 to be able to communicate.
Port FastEthernet 0/1 needs to be configured as an access link on both switches.
A router is required for hosts on Sw11 in VLANs 10 and 15 to communicate with hosts in the same VLAN on Sw12.

The access link needs to be configured in multiple VLANs.
The link between the switches is configured in the wrong VLAN
The link between the switches needs to be configured as a trunk.
VTP is not configured to carry VLAN information between the switches.
Switch IP addresses must be configured in order for traffic to be forwarded between the switches.

802.1Q native VLAN frames are untagged by default.
802.1Q trunking ports can also be secure ports.
802.1Q trunks can use 10 Mb/s Ethernet interfaces.
802.1Q trunks require full-duplex, point-to-point connectivity.
802.1Q trunks should have native VLANs that are the same at both ends.

It is a layer 2 messaging protocol which maintains vlan configurations across network.
It includes an 8-bit field which specifies the priority of a frame.
It is used exclusively for tagging vlan frames and does not address network reconvergence following switched network topology changes.
It modifies the 802.3 frame header and thus requires that the FCS be recomputed.
It is a trunking protocol capable of earring untagged frames.
