220-1102 Practice Question: A small business wants to migrate its on-premises…
A small business wants to migrate its on-premises file server to a cloud service to reduce hardware maintenance costs. The data must be accessible from any device with an internet connection and should support real-time collaboration. Which cloud service model best meets these requirements?
⚠ Common exam trap
CompTIA often tests the misconception that IaaS is the best choice for any migration away from on-premises hardware, but the trap here is that IaaS still requires the customer to manage the operating system and application stack, whereas SaaS provides a fully managed, collaboration-ready solution that directly meets the access and real-time editing requirements.
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
✓
Software as a Service (SaaS)
SaaS (Software as a Service) is the correct choice because it provides a ready-to-use file-sharing and collaboration application (e.g., Microsoft 365 SharePoint, Google Workspace Drive) that is accessed via a web browser or client over the internet. This eliminates the need to manage underlying hardware or platform, directly meeting the requirements for device-agnostic access and real-time collaboration without any infrastructure overhead.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Infrastructure as a Service (IaaS)
Why it's wrong here
Infrastructure as a Service (IaaS) delivers fundamental computing resources such as virtual machines, storage, and networking components over the internet. While it offers flexibility for deploying custom file servers, the small business would still be responsible for installing, configuring, and maintaining the operating system, file server software, and all associated security patches and updates. This model does not provide a ready-to-use, fully managed file collaboration solution.
- ✗
Platform as a Service (PaaS)
Why it's wrong here
Platform as a Service (PaaS) offers a complete development and deployment environment in the cloud, including operating systems, programming language execution environments, databases, and web servers. It is primarily designed for developers to build, run, and manage custom applications without the complexity of managing the underlying infrastructure. This service model does not provide a pre-configured, off-the-shelf solution for file storage and real-time collaboration.
- ✓
Software as a Service (SaaS)
Why this is correct
Software as a Service (SaaS) delivers fully managed, ready-to-use applications directly to end-users over the internet, eliminating the need for local installation, maintenance, or infrastructure management. For a small business seeking to migrate its file server, a SaaS solution like cloud-based file storage and collaboration suites provides immediate accessibility, real-time collaboration features, and automatic updates, perfectly aligning with the requirement for a turnkey solution without managing any underlying hardware or software.
- ✗
Desktop as a Service (DaaS)
Why it's wrong here
Desktop as a Service (DaaS) provides virtualized desktop environments to users over the internet, allowing them to access a full desktop experience from any device. While files can be accessed and stored within these virtual desktops, DaaS is fundamentally about delivering a complete user workspace, not specifically a centralized, shared file storage and collaboration service for an entire organization. Implementing DaaS solely for file server migration would be an inefficient and overly complex solution for the stated business need.
