FC0-U71 Practice Question: Developing a mobile app and wants to ensure it…
A company is developing a mobile app and wants to ensure it works on both iOS and Android without writing separate codebases. Which approach should be used?
⚠ Common exam trap
Test-takers frequently confuse 'cross-platform development' with 'web-based development,' thinking a responsive web app can replace a native mobile app, but the question specifically requires app store distribution and device hardware access, which only cross-platform or native development can provide.

Correct answer & explanation
✓
Cross-platform development
Cross-platform development allows a single codebase (e.g., using frameworks like React Native, Flutter, or Xamarin) to compile into native apps for both iOS and Android, eliminating the need to write separate codebases for each platform. This approach leverages shared logic and UI components while still producing platform-specific binaries that can access native device features.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Cross-platform development
Why this is correct
Cross-platform frameworks like React Native allow one codebase for multiple platforms.
- ✗
Native development
Why it's wrong here
Native development requires separate codebases for each platform.
- ✗
Web-based development
Why it's wrong here
Web-based apps run in a browser and may not access all device features.
- ✗
Cloud-based development
Why it's wrong here
Cloud-based refers to where processing happens, not platform compatibility.
