What are two attributes of a VLAN?
| A. |
A VLAN defines a collision domain. | |
| B. |
A VLAN defines a broadcast domain. | |
| C. |
Broadcasts are flooded to all VLANs. | |

| E. |
A Layer 3 device is required to route packets between VLANs. | |
| F. |
A Layer 2 device is required to route packets between VLANs. |
In computer networking, a single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a virtual local area network, virtual LAN or VLAN.
A router (Layer 3 device) serves as the backbone for network traffic going across different VLANs.
