CCNA Data Center Question of the Week: Attributes of a VLAN

What are two attributes of a VLAN? (Choose two.)

A. A VLAN defines a collision domain.
B. A VLAN defines a broadcast domain.
C. Broadcasts are flooded to all VLANs.
D. Collisions 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.

Reveal Answer

Answer: B and E.

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. This domain is now referred to as a virtual local area network, virtual LAN or VLAN.  A router (Layer 3 device) serves as the method for interVLAN traffic going to flow across multiple VLANs.
