Question 1

What is the primary goal of 'continuous integration' (CI) in a software development pipeline?

Accepted Answer

To detect integration errors quickly by merging and building developer changes frequently

Answer

CI integrates code changes into a shared repository frequently, running automated builds and tests to catch integration bugs early.

Question 2

Which software architectural style uses an 'event bus' where producers publish events and consumers subscribe independently, with no direct coupling?

Accepted Answer

Event-Driven Architecture (EDA)

Answer

EDA decouples producers and consumers through an event bus or broker (e.g., Kafka, RabbitMQ), enabling asynchronous, loosely-coupled communication.

Question 3

In software project estimation, what does the 'COCOMO II' model primarily use as a size input?

Accepted Answer

Function points or source lines of code (SLOC)

Answer

COCOMO II uses SLOC or function points as primary size measures and applies cost drivers and scale factors to estimate effort and schedule.

Question 4

What is 'dependency injection' and what problem does it solve?

Accepted Answer

A design pattern where dependencies are provided externally rather than created internally; solves tight coupling

Answer

Dependency injection supplies an object's dependencies from outside (via constructor, setter, or interface), reducing coupling and improving testability.

Question 5

Which property of a cryptographic hash function ensures that finding two different inputs with the same hash output is computationally infeasible?

Accepted Answer

Collision resistance

Answer

Collision resistance means it is computationally infeasible to find any two distinct inputs x and y such that H(x) = H(y).
