• to segregate traffic within a network (VLANs keep traffic from different networks separated when traversing shared links and devices within a topology)

• to protect the frames when traversing shared links

Which are the tagging modes?

• Translation and Transition

• Translation and Transparent

• Transparent and Traditional

Which is the main difference between Translation Mode vs. Transparent Mode?

• Spokes add a VLAN Tag vs. Spokes don't add a VLAN Tag

• Hub accepts just 2 spokes vs. Hub accepts multiple spokes

• VLAN Tag is added by the Hub vs. VLAN Tag is not added by the Hub
