Eight virtual machines run on one physical server; the server has two physical Ethernet NICs. Which answer describes a method that allows all eight VMs to communicate?
- The VMs must share two IP addresses and coordinate to avoid using duplicate TCP or UDP ports.
- The hypervisor acts as an IP router using the NICs as routed IP interfaces.
- Each VM uses a virtual NIC that is mapped to a physical NIC.
- Each VM uses a virtual NIC that logically connects to a virtual switch.
Explanation: Hypervisors create a virtual equivalent of Ethernet switching and cabling between the VMs and the physical NICs. The VMs use a virtual NIC (vNIC). The hypervisor uses a virtual switch (vswitch), which includes the concept of a link between a vswitch port and each VM’s vNIC. The vswitch also connects to both physical NICs. The switch can then be configured to create VLANs and trunks as needed.
