Software Engineering Trivia 5

Question 1

Which algorithm traversal visits all nodes at the current depth level before moving to the next level?

Accepted Answer

Breadth-First Search (BFS)

Answer

BFS uses a queue to explore all neighbors at the present depth prior to moving on to nodes at the next depth level.

Question 2

What is 'technical debt' in software engineering?

Accepted Answer

The implied cost of rework caused by choosing a quick, easy solution instead of a better but longer-term approach

Answer

Technical debt is the future cost of maintaining or reworking expedient but suboptimal code, analogous to financial debt that accrues interest.

Question 3

In the context of microservices, what is an API gateway?

Accepted Answer

A single entry point that routes client requests to appropriate backend microservices

Answer

An API gateway acts as a reverse proxy that aggregates requests, handles cross-cutting concerns like auth and rate limiting, and routes to downstream services.

Question 4

What does the CAP theorem state about distributed systems?

Accepted Answer

A distributed system can guarantee at most two of: Consistency, Availability, and Partition tolerance

Answer

The CAP theorem (Brewer's theorem) states that a distributed system can provide at most two of the three guarantees at the same time.

Question 5

Which software testing technique tests the internal workings and code paths of a system, requiring knowledge of the source code?

Accepted Answer

White-box testing

Answer

White-box (or clear-box) testing exercises specific code paths, branches, and conditions with full knowledge of the implementation.
