Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Enable USB 3.0 controller in the VM settings

  Why it's wrong here

  Enabling the USB 3.0 controller within the virtual machine settings merely configures the VM to emulate a USB 3.0 port, allowing it to recognize and utilize virtual USB devices at higher speeds. While this is a prerequisite for high-speed USB devices, it does not automatically grant the VM direct access to a physical USB device connected to the host. For a licensing dongle, the VM requires explicit hardware passthrough to interact with the physical device's unique identifier and security features, which is a separate configuration step.

• ✗

  Configure network bridging for the VM

  Why it's wrong here

  Configuring network bridging for a virtual machine allows it to connect directly to the physical network, obtaining its own IP address and appearing as a separate device on the network alongside the host. This setting exclusively pertains to network connectivity and network interface card (NIC) emulation, enabling the VM to participate in the physical network infrastructure. It has no bearing whatsoever on the VM's ability to access or utilize physical USB devices connected to the host machine, as USB device access is managed through entirely different virtualization features.

• ✓

  Enable USB passthrough and attach the dongle to the VM

  Why this is correct

  Enabling USB passthrough is the critical step, as it dedicates a physical USB port or a specific USB device from the host directly to the virtual machine. This mechanism allows the VM to bypass the host operating system's USB stack and gain direct, exclusive hardware access to the licensing dongle, treating it as if it were physically connected to the VM itself. Once passthrough is configured, attaching the dongle to the VM ensures the virtualized software can properly detect and validate the physical security key, which is essential for most licensing dongles.

• ✗

  Install the dongle driver on the host OS

  Why it's wrong here

  Installing the dongle driver on the host operating system is incorrect because, with USB passthrough enabled, the host OS no longer directly manages the dongle; its control is relinquished to the guest. The virtual machine effectively "owns" the device, requiring its own set of drivers. Therefore, the necessary drivers must be installed *within* the guest operating system of the VM itself, allowing the virtualized application to properly communicate with and utilize the passed-through hardware licensing dongle, just as it would on a physical machine.
