You are connecting an access point and it is set to root. What does extended service set ID mean?

• That you have more than one access point and they are in the same SSID connected by a distribution system
• That you have more than one access point and they are in seperate SSIDs connected by a distribution system
• That you have multiple access points, but they are placed physically in different buildings
• That you have multiple access points, but one is a repeater access point
