220-1102 Operating Systems Practice Question

A technician is setting up a Windows 10 laptop for a user who needs to keep personal documents separate from work files. The user wants to use both a local account and a Microsoft account to achieve this separation. Which configuration should the technician implement?

⚠ Common exam trap

Many exam-takers confuse 'adding a work or school account' (which only provides SSO and resource access) with creating a separate user profile, leading them to choose Option C incorrectly.

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

✓

Create a local account and a Microsoft account as separate user accounts

Creating separate user accounts—one local and one Microsoft account—ensures that each account has its own user profile, file storage, and application settings. This keeps personal documents completely isolated from work files, as each account operates in its own sandboxed environment within Windows 10.

Answer analysis

Option-by-option breakdown

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

  • ✓

    Create a local account and a Microsoft account as separate user accounts

    Why this is correct

    By creating two separate user accounts (one local, one Microsoft), each will have its own profile and file storage. The user can choose which account to use for personal work and which for business, keeping files isolated.

  • ✗

    Use one Microsoft account and enable Family Safety

    Why it's wrong here

    Enabling Family Safety on a single Microsoft account does not create a second user profile; it merely applies parental-control policies such as screen time limits, web filtering, and activity reporting to the existing profile. All files, AppData, and registry settings remain under C:\Users\<username>, so personal and business data continue to share the same storage and permissions. The feature is designed to restrict a child's usage, not to partition an adult's work and personal files, so it provides no isolation.

  • ✗

    Add a work or school account to the existing Microsoft account

    Why it's wrong here

    Adding a work or school account to a Microsoft account allows access to work resources like email and VPN but does not create a separate user profile. Files would still reside under the same user profile.

  • ✗

    Switch to using a Microsoft account only

    Why it's wrong here

    Switching the laptop to use only a Microsoft account changes the sign-in credential but keeps the same Security Identifier (SID) and profile path, meaning the user's NTUSER.DAT, AppData, OneDrive, and Documents remain a single merged container. Personal and work files share the same Desktop and are subject to OneDrive known-folder sync, which can unintentionally upload both categories to the same cloud account. Without a second SID and a distinct profile directory, there is no built-in mechanism to separate business data from personal data; this option merely adds cloud sync, not isolation.
