Ports may be in the Listening, Learning, Discarding and Forwarding states.
All ports on the root bridge are root ports
All ports on the root bridge are Designated ports
All ports on the root bridge are Forwarding
Spanning tree will choose the path with the highest root path cost
Spanning tree will choose the path with the lowest root path cost
The network layer is responsible for path determination and logical addressing.
The transport layer controls access to the physical media.
TCP and UDP are network layer protocols.
TCP and UDP are transport layer protocols
The bridge learns destination mac addresses from frames and places them in the bridging table so that frames may be sent to the correct port and filtered from others
The bridge learns source mac addresses and places them in the bridging table so that frames may be sent to the correct port and filtered from others
The last unicast frame in a traffic flow must be flooded by the bridge.
Broadcast frames are filtered by default on transparent bridges.

The router will send traffic to the next hop 172.16.5.5 due to the higher priority. If reachability to this neighbor is lost, packets will be sent to 172.16.1.2
The router will send packets to the address of 172.16.1.2 due to the lower administrative distance, if reachability to this neighbor is lost, packets will be sent to 172.16.5.5
A VLAN can be used to group ports on a switch into different broadcast domains
Hosts attached to ports in the same VLAN will be in the same IP network
Hosts attached to ports in the same VLAN can be in different IP networks
Hosts attached to ports in different broadcast domains will need to communicate via a router
VLANs can be used to segment traffic according to the organisational structure (e.g. which department users are from).
Hosts attached to ports in different broadcast domains do not need to communicate via a router
