220-1102 Operating Systems Practice Question
A technician needs to create a new partition on a Windows 10 computer that has unallocated space on the hard drive. Which built-in tool should the technician use?
⚠ Common exam trap
A common mix-up: candidates confuse Device Manager (hardware drivers) with Disk Management (storage management) because both are in the Computer Management console, but only Disk Management can create partitions.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Disk Management
Disk Management (diskmgmt.msc) is the built-in Windows 10 tool specifically designed for managing hard drive partitions, including creating new partitions on unallocated space. It provides a graphical interface to initialize disks, create simple or spanned volumes, and assign drive letters, making it the correct choice for this task.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Disk Management
Why this is correct
Disk Management is the correct tool because it is the Microsoft Management Console (MMC) snap-in (diskmgmt.msc) specifically designed to manage physical disks, partitions, and volumes. In this GUI, you can right-click an unallocated region of a basic disk and choose 'New Simple Volume' to create a partition, assign a drive letter, and format it with a filesystem. It supports both MBR and GPT partition styles and also allows shrinking, extending, and deleting partitions, making it the only option here that directly fulfills the task.
- ✗
Device Manager
Why it's wrong here
Device Manager is not the correct option because its purpose is to enumerate and manage hardware devices and their drivers, not to manage disk layout or partitioning. While it does display 'Disk drives' under a separate category, that view only lets you view device status, update drivers, enable/disable the device, or uninstall it—none of which create, delete, or format partitions. Partitioning requires disk-level tooling that operates on the partition table, not the device driver stack.
- ✗
File Explorer
Why it's wrong here
File Explorer is not the correct option because it operates at the file and folder level, not at the partition or volume level. It can display and navigate already-formatted volumes, and it even offers 'Format' from a drive's context menu, but formatting an existing volume is not the same as creating a new partition. To create a partition, you must first have unallocated space on a disk, and File Explorer provides no interface to allocate that space, shrink existing volumes, or manipulate the partition table.
- ✗
Control Panel
Why it's wrong here
Control Panel is not the correct option because it contains system settings and configuration applets, but no dedicated partition-management utility. The closest path would be 'Administrative Tools' > 'Computer Management' > 'Disk Management', but that action opens the Disk Management MMC snap-in—not a Control Panel tool itself. Control Panel can manage disks in terms of functions like Storage Spaces or BitLocker, but it does not offer a direct way to create a new partition, so selecting it would still require you to eventually launch Disk Management.
