Difficulty: MediumVirtual Machine Resource Requirements and Hardware Support

A desktop technician is configuring a client-side hypervisor to host multiple virtual machines on a host workstation with limited physical drive space. To conserve physical storage upon initial creation while allowing the guest OS to expand its storage footprint as needed up to a set threshold, which virtual disk provisioning method should the technician configure?

  1. Thin provisioning (dynamically allocated disk)Answer
  2. B
    Thick provisioning (fixed-size disk)
  3. C
    Virtual memory swap file expansion
  4. D
    Raw disk pass-through mapping

Answer

Thin provisioning (dynamically allocated disk) is the correct choice because it consumes physical host storage space on demand as data is added, rather than pre-allocating the full virtual capacity.
Thin provisioning (dynamically allocated disk) creates a virtual disk file that initially uses only a small amount of physical host storage space for metadata and grows on-demand as data is written by the guest operating system, fitting the scenario's requirement for minimal initial host drive consumption.

Step-by-Step Solution

1
Analyze the storage constraint and operational requirement.
The host workstation has limited physical drive space and needs to run VMs whose physical disk footprint grows only as data is added.
Pre-allocating storage would instantly consume scarce host disk space.
2
Evaluate hypervisor virtual disk provisioning types.
Thin provisioning (dynamically allocated) allocates space on the physical host storage only when block writes occur in the guest OS.
This minimizes the initial physical storage footprint while supporting expansion up to the assigned ceiling.
