Question
An administrator is provisioning a new VM that will host tape backup software. The VM will need to communicate with a tape library that is connected to the host via multimode fiber. Which of the following interfaces will need to be provisioned on the VM in order to communicate with the tape library?
Options
- AvNIC
- BvSwitch
- CvHBA
- DFCoE

Why each option
To enable a VM to communicate with a tape library connected via fiber to the host, a virtual Host Bus Adapter (vHBA) must be provisioned within the VM.
A vNIC (virtual Network Interface Card) is used for network communication (TCP/IP), not for direct Fibre Channel access to storage or tape devices.
A vSwitch (virtual Switch) is a component on the host that manages network traffic between VMs and between VMs and the physical network, not for direct Fibre Channel access.
A tape library connected via multimode fiber implies a Fibre Channel (FC) connection, which typically uses a Host Bus Adapter (HBA) on the physical host. To grant a VM direct access to a Fibre Channel storage device or tape library, a virtual Host Bus Adapter (vHBA) needs to be configured within the VM, often leveraging NPIV (N-Port ID Virtualization).
FCoE (Fibre Channel over Ethernet) is a protocol that transports Fibre Channel frames over Ethernet networks, but it's not an interface type provisioned within a VM itself for direct access; a vHBA would still be the logical interface for Fibre Channel.
