Question 16 options:

	The number of broadcast domains is increased, thus minimising the impact of broadcast storms.
	The number of broadcast domains is reduced, thus minimising the impact of broadcast storms.
	VLANs make it easier for IT staff to configure new logical groups, because the VLANs all belong to the same subnet.
	A higher level of network security can be reached by separating sensitive data traffic from other network traffic.
	Switches can route packets between VLANs based on their MAC addresses.
	A more efficient use of bandwidth can be achieved as switches can send frames for different VLANs across the same link at the same time.
	LAN devices can be grouped by department and/or function, and not by physical location.
