Question 1

Which metric measures the number of linearly independent paths through a program's control flow graph?

Accepted Answer

Cyclomatic complexity

Answer

Cyclomatic complexity (V(G) = E − N + 2P) quantifies independent paths, providing a lower bound on the number of test cases needed for full branch coverage.

Question 2

What distinguishes 'eventual consistency' from 'strong consistency' in distributed databases?

Accepted Answer

Strong consistency guarantees all nodes reflect the latest write immediately; eventual consistency allows temporary divergence

Answer

Strong consistency ensures all nodes see the same data at the same time, while eventual consistency allows replicas to diverge temporarily and converge over time.

Question 3

In the context of software requirement engineering, what is a 'non-functional requirement' (NFR)?

Accepted Answer

A requirement that defines system qualities such as performance, security, or scalability

Answer

NFRs specify system quality attributes — how well it performs, how secure it is, how scalable — rather than what specific behaviors it exhibits.

Question 4

Which Git workflow strategy maintains a single 'main' branch where all developers integrate short-lived feature branches multiple times per day?

Accepted Answer

Trunk-Based Development

Answer

Trunk-Based Development keeps all work on one main branch with very short-lived branches, enabling continuous integration and reducing merge conflicts.

Question 5

What is the key difference between 'black-box testing' and 'white-box testing'?

Accepted Answer

Black-box testing tests without knowledge of internal structure; white-box testing uses knowledge of the code

Answer

Black-box testing derives test cases from specifications alone, while white-box testing designs tests based on internal code structure and logic.
