The Cisco Nexus 1000V is intended to address which disadvantage of the VMware vSphere solution?
The correct answer is C. Network administrators lack control of the access layer of the network. The Cisco Nexus 1000V addresses the lack of network administrator visibility and control over the virtual access layer in VMware vSphere environments.

Why each option
The Cisco Nexus 1000V addresses the lack of network administrator visibility and control over the virtual access layer in VMware vSphere environments.
VMware vSphere already supports rapid VM deployment without requiring physical network changes through pre-configured VLANs and virtual switches; this is not the disadvantage the Nexus 1000V was designed to solve.
ESX/ESXi hosts run multiple virtual machines simultaneously on a single physical host; the one-host-per-VM premise is factually incorrect.
In a standard VMware vSphere deployment, virtual switching is managed by virtualization or server administrators through the vSwitch, leaving network teams with no visibility or policy control at the virtual access layer; the Nexus 1000V replaces the vSwitch with a Cisco NX-OS-based virtual distributed switch, giving network administrators familiar CLI control, port profiles, and consistent policy enforcement at the VM level.
The Nexus 1000V does not increase the count of physical infrastructure or virtual machines; it provides policy management and control for existing virtual network infrastructure.
