hi djerk
the difference is that protected ports have local significance only. you can only isolate clients that are connected to the same switch. if the clients you want to isolate are connected to two different switches you need to use private vlans.
with private vlans there are three possible states of a port: isolated, promiscuous and community. an isolated port can only communicate with a promiscuous one, community ports can communicate with each other and the promiscuous port. you need extra (secondary) vlans for a private vlan solution.

good luck for the exam, remember the chainsaw...
