MS-900 question #162 exhibit

Answer Area

  • Using OneDrive for Business as a target for backups is an example of platform as a service (PaaS).No
  • Using OneDrive for Business in Office 365 Excel Online to open Excel files is an example of software as a service (SaaS).Yes

Explanation

OneDrive for Business and Office 365 are classified as Software as a Service (SaaS) offerings, not Platform as a Service (PaaS), regardless of the specific use case.

Approach. For Statement 1 ('Using OneDrive for Business as a target for backups is an example of platform as a service...'), select 'No'. OneDrive for Business is inherently a Software as a Service (SaaS) product. A Platform as a Service (PaaS) provides an environment for developers to build, host, and deploy applications (e.g., Azure App Service, Azure SQL). Using a SaaS product to store backups does not change its service model to PaaS. For Statement 2 ('Using OneDrive for Business in Office 365 Excel Online to open Excel files is an example of software as a service...'), select 'Yes'. Office 365 (including Excel Online and OneDrive) provides fully managed applications hosted by Microsoft that end-users consume directly over the internet. This is the exact definition of SaaS.

Common mistakes.

  • common_mistake. A common mistake is assuming that because you are using OneDrive for data storage (a 'target' for backups), it acts like infrastructure or a platform component (like Azure Blob Storage, which is often categorized under IaaS/PaaS). Candidates must remember that Microsoft 365/Office 365 products are universally SaaS.

Concept tested. Cloud Service Models (IaaS, PaaS, SaaS) and the classification of Microsoft 365 ecosystem services.
