FC0-U71 Software Development Concepts Practice Question
A development team is selecting a programming language for a new project that must run directly on many different operating systems with minimal changes to the source code. The team also wants strong built-in support for object-oriented programming. Which TWO characteristics should the team prioritize when evaluating languages? (Choose two.)
⚠ Common exam trap
The trap here is choosing low-level control or vendor tooling as if it improved cross-platform compatibility, when it usually reduces portability.
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
✓
Object-oriented programming support
Portability enables the same source code to run across many operating systems with minimal changes, and object-oriented programming support provides the classes, objects, and inheritance the team wants. Together these two characteristics match the stated requirements. Low-level memory addressing, single-vendor tooling, and compiling to one platform's machine code all work against cross-platform goals and do not provide the requested OOP 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.
- ✓
Object-oriented programming support
Why this is correct
Object-oriented programming support lets developers model data and behavior together using classes, objects, inheritance, and encapsulation. The team explicitly wants strong built-in OOP support, so a language with first-class constructs for classes and objects is required. This characteristic is one of the two stated priorities in the scenario.
- ✗
Compilation to a single operating system's machine code
Why it's wrong here
Compiling to one operating system's native machine code produces binaries that run only on that platform, which contradicts the requirement to run on many operating systems. Portability usually comes from intermediate representations or runtimes, not from platform-specific binaries. This option also does not address the desire for strong object-oriented programming support.
- ✗
Low-level memory addressing
Why it's wrong here
Low-level memory addressing, such as raw pointers and manual memory management, gives fine control over hardware but is not what the team asked for. It often reduces portability because code may depend on a specific architecture or operating system. The scenario emphasizes running on many operating systems with minimal changes and strong OOP, not direct hardware manipulation.
- ✓
Portability
Why this is correct
Portability means code can run on multiple platforms with little or no modification, often because the language relies on a runtime or virtual machine rather than platform-specific machine code. This directly addresses the requirement to run on many operating systems with minimal source changes. Languages designed for portability make cross-platform deployment far easier for the team.
- ✗
Proprietary single-vendor tooling
Why it's wrong here
Proprietary single-vendor tooling ties development to one vendor's environment, which can limit cross-platform deployment and increase lock-in. The team wants to run on many operating systems with minimal source changes, so vendor-specific tooling works against that goal. It also has no direct relationship to providing built-in object-oriented programming features.
