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

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.
Correct Answer: BE
Explanation/Reference:
"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."
