A network administrator is extending a network beyond the primary equipment location.

When extending a network beyond the primary equipment location, additional access/distribution switches are typically placed in an IDF (Intermediate Distribution Frame). Network+ (N10-009) infrastructure objectives differentiate between the MDF and IDF: the MDF is the main, central wiring/equipment location (often where core switches, routers, WAN demarcation, and main cross-connects reside). As a building grows or spans multiple floors/areas, an IDF is used as a secondary wiring closet to reduce cable runs, provide local switching, and aggregate user access connections back to the MDF using backbone cabling (often fiber). This supports scalability, cable management, and performance by keeping horizontal runs within recommended distance limits.

VPC (Virtual Private Cloud) is a cloud networking construct, not a physical wiring location. VXLAN is an overlay tunneling technology used in virtualized/data center networks, not where you physically install switches. The question specifically references extending the network beyond the primary equipment location, which is a classic use case for deploying an IDF to host additional switches closer to endpoint areas while uplinking back to the MDF.
