Explanation

Assigning VLANs to devices makes the most sense when traffic patterns are known (C), because VLANs are a planning tool - you segment the network based on how devices actually communicate, grouping devices with similar traffic flows to reduce broadcast domains and improve security. Spanning a VLAN across multiple zones (A) is the opposite of what VLANs are designed for - they exist to isolate traffic, not bridge security boundaries. Fluctuating traffic patterns (B) would make VLAN assignments unstable and administratively burdensome, since you'd constantly reassign ports. Consolidating resources (D) is a server/virtualization concern, not a primary VLAN use case.

Memory tip: Think of VLANs like office seating charts - you only assign seats once you know who needs to work together. You don't rearrange desks every day (fluctuating patterns), and you don't seat everyone in one giant room (spanning zones).
