* Virtual Switch Design in NSX (Correct Answer - A):
* NSX uses the N-VDS (NSX Virtual Distributed Switch) or VDS (vSphere Distributed Switch) as the foundational virtual switch.
* When designingvirtual switch architecture, key considerations include:
* Number of Virtual Machines (VMs):
* Determinesnetwork scalabilityandbandwidth requirements.
* Network Performance:
* Ensuring theright uplink profiles and NIC configurationsto meet performance demands.
* Security Requirements:
* Micro-segmentation and Distributed Firewall (DFW)capabilities must be planned at thevirtual switch level.
* Incorrect Options:
* (B - Server hardware, OS, and applications):
* These impactworkload performancebutdo not define virtual switch design.
* (C - VLAN, Subnet, and Routing Design):
* VLANs and routing areimportant for physical network integrationbut arenot the primary focusof virtual switch design.
* (D - Network Topology and Availability):
* Whiletopology matters, virtual switch design isfocused on software-based switching rather thanphysical topology.
