MS-900 Describe Microsoft 365 apps and services Practice Question
A company wants to securely share a large video file (2 GB) with an external partner without using email attachments. Which Microsoft 365 service should they use?
⚠ Common exam trap
Many candidates confuse Microsoft Stream as the service for sharing video files because of the word 'video,' but Stream is for hosting and streaming, not for secure file sharing with external partners, which requires a storage and sharing service like OneDrive.
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
✓
Microsoft OneDrive
Microsoft OneDrive is the correct choice because it allows sharing large files (up to 250 GB per file) via secure, expiring links with external users, without relying on email attachments. It integrates with Microsoft Entra ID for access control and supports granular permissions like view or edit, making it ideal for ad-hoc external file sharing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft SharePoint
Why it's wrong here
SharePoint is primarily designed for internal team collaboration and document management, providing a central repository for an organisation's content. While it can store large files and facilitate external sharing, its mechanism typically involves granting access to a site or library for ongoing collaboration, which is not the most direct method for a one-off secure transfer of a single large file to an external partner. It would be the correct choice for establishing a shared workspace or document repository for a project team.
- ✗
Microsoft Teams
Why it's wrong here
Microsoft Teams enables file sharing through its chat and channel infrastructure, which relies on underlying SharePoint and OneDrive storage. However, external sharing via Teams requires enabling guest access or configuring tenant-level sharing policies, making it cumbersome for a one-off transfer. Moreover, files shared in Teams conversations are subject to a 2GB per-file upload limit, and the link-sharing options are not as granular as OneDrive's password and expiration controls.
- ✗
Microsoft Stream
Why it's wrong here
Microsoft Stream is a video-centric service designed for uploading, organizing, and playing enterprise videos such as meetings, webinars, and training content. While a 2GB video file could technically be uploaded to Stream, its focus is on video lifecycle management with features like transcripts and captions, not on providing secure, external, one-time file sharing. Stream's sharing model is oriented toward internal audiences and does not offer the same direct link-sharing capabilities with expiration and password protection as OneDrive.
- ✓
Microsoft OneDrive
Why this is correct
Microsoft OneDrive provides personal cloud storage with a dedicated 'Share' workflow that generates secure links for external recipients, including an option to set an expiry date and require a password. A 2GB file is well within OneDrive's file-size limit of 250GB, and the service supports both view and edit permissions without requiring external users to have a Microsoft account. This makes OneDrive the optimal choice for a single, secure, ad-hoc large-file transfer to an external partner.
