While reading the book CCENT/CCNA ICND1Official Exam Certification Guide  by Wendell Odom – Chapter 7 Ethernet LAN Switching Concepts, another concept confusion arose. The table below lists some of the benefits of segmenting Ethernet devices using Hubs, Switches, and Routers.




After which the chapter goes into discussion of VLANs. It says that a switch creates multiple broadcast domains by putting some interfaces into on VLAN and other interfaces into other VLANs. These individual broadcast domains created by the switch are called Virtual LANs.


Based on the table, if I encounter a question on the exam that asks whether a switch is able to create multiple broadcast domains, I would answer no. But if you read the concept of VLAN, then a switch IS able to create multiple broadcast domains—right? So are switches able to create multiple broadcast domains or not? Can someone help me understand this?
