Ingrid P.Dec 16, 2025B and C are your two correct answers here. A Distributed Virtual Switch is the core switching fabric that handles network traffic between VMs and the physical network, and a Virtual Network Interface is what each VM uses to actually connect to that network, so these two together form the foundational components of a vSphere virtual network.
Grace U.Dec 17, 2025Worth noting that if the exam presents a standard vSwitch instead of a distributed one, that answer is just as valid for "foundational switching," so do not let the word "distributed" anchor you into thinking only a DVS counts.
Samuel O.Dec 20, 2025The "mam" in the question is a typo for "main," just so no one spirals on that. Anyway, B and C are the right picks here because a Distributed Virtual Switch handles the switching fabric side of the virtual network and a Virtual Network Interface is literally how the VM connects to that network, while A and D are NSX constructs that sit on top of vSphere networking rather than being core components of vSphere virtual networking itself.
Carlos M.Jan 3, 2026Saw this exact wording on mine, picked B and C without blinking. vSwitch plus vNIC, that is the virtual network foundation, the other two are NSX territory so eliminate fast and move on.
Samuel O.Jan 5, 2026That is solid instinct, though I would add that knowing *why* NSX components get eliminated saves you on the scenario variants where they sneak a load balancer or firewall question in NSX clothing.
