Sample BUT Informatique Practice Questions

Try these sample questions to review concepts for the BUT Informatique exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In object-oriented programming (OOP), which principle dictates that internal object state should be hidden from external modification and only accessible through defined public interfaces?

A.Inheritance

B.Encapsulation

C.Polymorphism

D.Dynamic dispatch

Explanation: Encapsulation bundles state (data attributes) and behavior (methods) together within a class while restricting direct external access to internal representations. Mutators (setters) and accessors (getters) or public methods provide controlled interfaces, safeguarding object invariants.

2Which Gang of Four (GoF) design pattern ensures that a class has exactly one instance and provides a global point of access to that instance throughout the application runtime?

A.Factory Method

B.Singleton

C.Prototype

D.Builder

Explanation: The Singleton pattern restricts instantiation of a class to a single object, typically implemented using a private constructor, a static private instance variable, and a public static getter method. It is commonly applied to thread pools, configuration managers, and logging services.

3In Java and C++, what is the fundamental difference between method overloading and method overriding?

A.Overloading occurs within the same class using identical parameter lists; overriding occurs in subclasses with differing parameter lists.

B.Overloading occurs when methods share the same name but differ in parameter signatures; overriding redefines an inherited method in a subclass with the exact same signature.

C.Overloading is resolved dynamically at runtime; overriding is resolved statically at compile time.

D.Overloading requires the abstract keyword; overriding requires the final keyword.

Explanation: Method overloading provides multiple methods within the same scope sharing the same name but differing in parameter types, count, or order, resolved at compile time (static polymorphism). Method overriding occurs when a subclass redefines an inherited method using the exact same signature and compatible return type, resolved at runtime (dynamic polymorphism).

4Which SOLID software design principle states that software entities (classes, modules, functions) should be open for extension but closed for modification?

A.Single Responsibility Principle (SRP)

B.Open/Closed Principle (OCP)

C.Liskov Substitution Principle (LSP)

D.Dependency Inversion Principle (DIP)

Explanation: The Open/Closed Principle (formulated by Bertrand Meyer) requires systems to allow adding new features or behaviors by writing new classes or extending abstractions without altering established, tested source code. Polymorphism and strategy interfaces are classic implementations of OCP.

5In Git version control, which command creates a new local branch named 'feature-auth' and switches the working directory to it in a single operation?

A.git branch -m feature-auth

B.git checkout -b feature-auth

C.git merge feature-auth

D.git commit -b feature-auth

Explanation: The command 'git checkout -b <branch>' creates a new branch pointer pointing to the current HEAD commit and updates HEAD to track that branch. In modern Git releases, 'git switch -c feature-auth' performs the identical branch creation and switch operation.

6What is the primary role of a mock object in automated unit testing frameworks such as JUnit or Mockito?

A.To execute comprehensive load and stress benchmarks against remote production clusters

B.To simulate external or complex dependencies with pre-programmed expectations and verify interactions

C.To compile intermediate bytecode into platform-native machine instructions

D.To inspect git commits and reject merge requests that lack 100% statement coverage

Explanation: Mock objects replace real external dependencies (such as databases, web APIs, or hardware drivers) with test doubles. They allow developers to isolate the unit under test, configure return values for specific inputs, and assert that expected methods were called with appropriate arguments.

7In Python, which dunder (magic) method is invoked when an object is instantiated to initialize its attribute values?

A.__new__(cls)

B.__init__(self)

C.__repr__(self)

D.__call__(self)

Explanation: The '__init__' method serves as the instance initializer in Python. While '__new__' is the static constructor that creates and returns the raw instance object, '__init__' receives that newly created instance as 'self' to populate its attributes.

8Which design pattern decouples an abstraction from its implementation so that both can vary independently, often utilizing object composition across two orthogonal class hierarchies?

A.Bridge

B.Adapter

C.Composite

D.Flyweight

Explanation: The Bridge pattern separates an abstraction (e.g., a cross-platform GUI window) from its implementation (e.g., Windows vs Linux rendering backends). By replacing inheritance with composition, both the abstraction hierarchy and implementation hierarchy can be extended without multiplying subclasses.

9In C++, which smart pointer provides exclusive ownership of a dynamically allocated heap object and automatically deletes the managed resource when it goes out of scope?

A.std::shared_ptr

B.std::unique_ptr

C.std::weak_ptr

D.std::auto_ptr

Explanation: 'std::unique_ptr' enforces unique, non-copyable ownership of a dynamically allocated heap resource. It can only be moved (via std::move), guaranteeing zero overhead compared to raw pointers while adhering to Resource Acquisition Is Initialization (RAII).

10What does the Liskov Substitution Principle (LSP) require regarding preconditions and postconditions when a subclass overrides a base class method?

A.Subclasses must strengthen preconditions and weaken postconditions.

B.Subclasses may weaken preconditions and strengthen postconditions, but cannot strengthen preconditions or weaken postconditions.

C.Subclasses must define identical preconditions and omit postconditions.

D.Subclasses must throw checked exceptions whenever preconditions differ.

Explanation: Under LSP (Design by Contract), a subtype must be usable wherever its supertype is expected. Therefore, an overriding method cannot demand more from the caller (preconditions cannot be strengthened, but may be weakened) and cannot guarantee less upon completion (postconditions cannot be weakened, but may be strengthened).

About the BUT Informatique Exam

The Bachelor Universitaire de Technologie (BUT) Informatique is France's premier three-year undergraduate university diploma in computer science (grade de licence, 180 ECTS, Level 6). Fixed by national decree (Arrêté du 15 avril 2022 Annexe 15, replaced by the Arrêté du 8 août 2023), it prepares software engineers, systems administrators, database specialists, and IT project managers. The curriculum combines a rigorous common core with specialized parcours starting in year 2: Réalisation d'applications (RACDV), Déploiement d'applications communicantes et sécurisées (DACS), Administration, gestion et exploitation des données (AGED), and Intégration d'applications (IAMSI). OpenExamPrep provides an English-language MCQ study adaptation of the national French competency framework; it does not replace the official IUT coursework, SAÉ projects, internships, or oral defenses.

Under the Arrêté du 15 avril 2022 (Annexe 15) — whose Informatique annexe was abrogated and replaced by the Arrêté du 8 août 2023, which carries the programme national currently in force — and France Compétences RNCP frameworks (e.g. RNCP41585, RNCP35475), the BUT Informatique is organized across 6 semesters (180 ECTS) conferring the national grade de licence (Level 6). Delivered by university Instituts Universitaires de Technologie (IUT), candidates are assessed through continuous evaluation (contrôle continu intégral CCI), multidisciplinary SAÉ projects, 22 to 26 weeks of workplace internships or alternance, and professional portfolio defenses. Each teaching unit (UE) is validated at 10/20, with compensation permitted within defined coherent UE groupings when the grouping average reaches 10/20 and every constituent UE is at least 8/20.

Time Limit

Three academic years (6 semesters, 180 ECTS)

Passing Score

10/20 to validate each competency UE; compensation within defined groupings requires an average of 10/20 with no UE below 8/20

Frequently Asked Questions

What is the BUT Informatique?

The Bachelor Universitaire de Technologie (BUT) Informatique is a three-year French national undergraduate degree (grade de licence, 180 ECTS, Level 6 RNCP) delivered by university Institutes of Technology (IUT). It provides comprehensive training in software development, algorithmics, database systems, networks, and IT project governance.
