* L2 Bridging & Subnet Consistency (Correct Answer - D):
* NSX L2 BridgingallowsVLAN-backed workloadsto communicate withoverlay-backed workloadsbyextending Layer 2 segmentsbetween on-premises and cloud environments.
* A fundamental requirement is that both locations use the same IP subnetto ensure seamless communication without additional routing.
* Incorrect Options:
* (A - Requires Geneve Encapsulation Over Public Internet):
* L2 bridgingis different fromL3 VPN or Geneve overlay networks. Geneve is used for NSX overlay transport, butL2 bridging does not require Geneve over the internet.
* (B - Only for Low-Latency Applications):
* L2 bridgingcan introduce latency, but it isnot restrictedto low-latency applications.
However, itshould be used carefully in high-latency environments.
* (C - Must Be in the Same Geographical Location):
* While proximityreduces latency, it isnot mandatory.Cross-region Layer 2 extensions can be implemented withVXLAN or NSX-T bridging, butperformance considerations are crucial.
