SK0-004 · Question #401
Which of the following should a systems administrator create to enable network connectivity on a virtual machine? (Choose two.)
The correct answer is B. A virtual network adapter E. A virtual switch. Virtual machine network connectivity requires both a virtual network adapter on the VM and a virtual switch to connect VMs to each other and to physical networks.

Why each option
Virtual machine network connectivity requires both a virtual network adapter on the VM and a virtual switch to connect VMs to each other and to physical networks.
A virtual network alone is a logical construct and cannot provide connectivity without both a virtual adapter on the VM and a virtual switch to link them.
A virtual network adapter (vNIC) is the software-emulated NIC assigned to the VM, providing it with a network interface through which it can send and receive traffic.
Virtual network storage is not a networking component - storage and networking are separate virtualized subsystems.
An extra physical NIC on the host server may improve throughput but is not required to enable basic virtual machine network connectivity.
A virtual switch connects virtual network adapters to physical network infrastructure and other VMs, functioning as the hypervisor-level switching fabric needed to route traffic between VMs and external networks.
