Explanation
VLANs provide two key benefits: (B) they segment broadcast domains - traffic is contained within each VLAN so broadcasts don't flood the entire network; and (D) they enable logical grouping of devices across different physical Layer 2 switches, so users/devices can be in the same logical network regardless of physical location. VLANs do not restrict who joins the network (that's 802.1X/NAC), do not make all devices accessible from everywhere (opposite is true), and they shrink, not extend, broadcast domains.
