1. A software development team is implementing a version control strategy
for a large-scale enterprise application. Which of the following best
describes the primary benefit of using a distributed version control system
such as Git?
A. Centralized repository control
B. Offline commit capability and branching flexibility
C. Reduced storage requirements
D. Elimination of merge conflicts
✔ Correct Answer: B (Offline commit capability and branching flexibility)
Explanation: Distributed version control systems like Git allow developers
to work offline, commit locally, and manage branches efficiently,
improving collaboration and flexibility.
2. A developer encounters a race condition in a multithreaded application.
What is the most effective solution?
A. Increase CPU allocation
B. Implement thread synchronization mechanisms
C. Reduce memory usage
D. Use a single-threaded model
✔ Correct Answer: B (Implement thread synchronization mechanisms)
, Explanation: Synchronization tools such as mutexes or locks ensure
controlled access to shared resources, preventing race conditions.
3. In object-oriented programming, which principle allows objects to take
multiple forms?
A. Encapsulation
B. Inheritance
C. Polymorphism
D. Abstraction
✔ Correct Answer: C (Polymorphism)
Explanation: Polymorphism enables methods to perform differently based
on the object context, enhancing flexibility and reuse.
4. A database administrator needs to ensure data integrity across multiple
related tables. Which concept should be applied?
A. Indexing
B. Normalization
C. Referential integrity
D. Denormalization
✔ Correct Answer: C (Referential integrity)
Explanation: Referential integrity enforces relationships between tables,
ensuring consistency of foreign keys.
5. Which HTTP status code indicates that a resource has been permanently
moved?
A. 200
B. 301
C. 404
D. 500
✔ Correct Answer: B (301)
Explanation: A 301 status code signals a permanent redirect to a new URL.
6. A developer wants to optimize API performance. Which approach is most
effective?
, A. Increase payload size
B. Implement caching mechanisms
C. Use synchronous calls only
D. Disable compression
✔ Correct Answer: B (Implement caching mechanisms)
Explanation: Caching reduces repeated processing and improves response
times.
7. What is the primary purpose of unit testing?
A. Test entire system integration
B. Validate individual components
C. Measure performance
D. Deploy code automatically
✔ Correct Answer: B (Validate individual components)
Explanation: Unit testing focuses on verifying the correctness of isolated
code units.
8. Which data structure operates on a FIFO principle?
A. Stack
B. Queue
C. Tree
D. Graph
✔ Correct Answer: B (Queue)
Explanation: A queue processes elements in First-In-First-Out order.
9. In RESTful APIs, which method is idempotent?
A. POST
B. GET
C. PATCH
D. CONNECT
✔ Correct Answer: B (GET)
Explanation: GET requests can be repeated without changing the resource
state.
