Explanation

Overlay networks (C) are the correct choice because they allow thousands of virtual network segments to be created on top of a single physical network using encapsulation protocols like VXLAN - which supports up to 16 million segment IDs, far exceeding the 4,094 VLAN limit and making multi-tenant environments at scale feasible.

Why the distractors are wrong:

• A. Remote Direct Memory Access (RDMA) - a low-latency memory transfer technology for high-performance computing; it has nothing to do with network segmentation.
• B. Virtual Connect FlexFabric - an HPE blade server interconnect technology for converged networking within a chassis; it doesn't provide thousands of logical network segments across a broader environment.
• D. Data Center Bridging (DCB) - a set of IEEE enhancements to Ethernet for lossless transport (used with storage and HPC traffic); it improves traffic reliability but doesn't create network segments.

Memory tip: Think "overlay" = layering a virtual network over physical hardware - like stacking thousands of transparent sheets on one table. When you see "thousands of segments" + "single physical network," that's the overlay use case.
