FC0-U71 Applications and Software Practice Question
A company uses a web-based application that runs in a browser and stores data on a remote server. Which of the following best describes this type of application?
⚠ Common exam trap
The trap is confusing hybrid apps with web apps — candidates see 'browser' and 'remote server' but pick hybrid because it sounds like a blend, missing that hybrid apps are installed on devices while web apps run in the browser.
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
✓
Web application
A web application runs in a browser and stores/processes data on a remote server, accessed over the network via HTTP/HTTPS. This matches the description exactly. Desktop, mobile, and hybrid apps run natively on a device rather than in a browser with server-side data storage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Desktop application
Why it's wrong here
A desktop application installs and executes locally on the user's machine, storing data on local disks or file shares. Browser delivery with remote server storage is the defining characteristic of a web application. Desktop software would be correct for locally installed productivity tools such as office suites.
- ✗
Mobile app
Why it's wrong here
A mobile app is packaged for a phone or tablet platform and distributed through an app store, typically installed natively. Running in a browser with server-side data storage describes a web application instead. Mobile apps would be correct when the requirement specifies native device installation and offline capability.
- ✗
Hybrid app
Why it's wrong here
A hybrid app wraps web content inside a native container for app-store distribution, adding device API access. The scenario describes pure browser execution with remote storage, which is a web application. Hybrid development would be correct when native packaging and device features are required alongside web technologies.
- ✓
Web application
Why this is correct
A web application runs in a browser and stores data on a remote server, exactly matching the stem's constraints. Unlike locally installed software, processing and storage occur server-side, with the browser acting as the client interface. This satisfies both the browser-based access and remote data storage requirements described.

Same concept, more angles
4 more ways this is tested on FC0-U71
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which of the following is a key difference between a web application and a desktop application?
medium- A.Desktop applications are stored on a remote server; web applications are installed locally.
- B.Web applications require an internet connection to run; desktop applications do not.
- ✓ C.Web applications run inside a browser and process data on a server; desktop applications run directly on the OS and have direct hardware access.
- D.Desktop applications require a subscription; web applications are free.
Why C: Option C is correct because it accurately captures the architectural distinction: web applications execute within a browser's sandboxed environment and typically rely on remote servers for data processing and storage, while desktop applications are installed on the local machine, run natively on the operating system, and can directly access hardware resources like the file system, GPU, and peripherals. This difference in execution environment and resource access is the fundamental technical differentiator between the two application models.
Variation 2. A user is selecting a web browser for everyday use. Which of the following is NOT a web browser?
medium- ✓ A.Microsoft Teams
- B.Apple Safari
- C.Mozilla Firefox
- D.Google Chrome
Why A: Microsoft Teams is a collaboration and unified communications platform, not a web browser. It provides chat, meetings, calling, and file sharing, and although it has a web client, that client runs inside a browser rather than being one. Safari, Firefox, and Chrome are all dedicated web browsers that render HTML, execute JavaScript, and manage HTTP/HTTPS sessions.
Variation 3. Which of the following best describes a web application?
medium- A.An application that runs only on mobile devices
- B.An application installed locally that has direct hardware access
- ✓ C.An application that runs within a web browser and processes data on a server
- D.An application that connects services using APIs
Why C: A web application is defined as an application that runs within a web browser and processes data on a server. This matches option C. The client-side runs in the browser, and server-side logic handles data processing.
Variation 4. A user is troubleshooting an issue with a web application that is only accessible through a browser. The user notes that the application runs slowly. Which component is most likely responsible for processing the application's server-side logic?
medium- A.Web browser
- B.Local firewall
- ✓ C.Web server
- D.Operating system
Why C: In a three-tier web application, the web server (e.g., Apache, Nginx, IIS) is the component that executes server-side logic — processing requests, running application code, and querying back-end resources before returning HTML/JSON to the browser. The browser only renders the response and runs client-side JavaScript; it does not execute server-side code. Therefore the web server is the component most likely responsible for the slow server-side processing.
