  5. A Layer 3 device is required to route packets between VLANs.

  6. A Layer 2 device is required to route packets between VLANs.

Answer: B,E

Explanation:

quot;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.quot;

quot;A router (Layer 3 device) serves as the backbone for network traffic going across different VLANs.quot;
