Question 1

Which architectural pattern separates an application into independently deployable services, each running in its own process and communicating via lightweight mechanisms?

Accepted Answer

Microservices architecture

Answer

Microservices architecture decomposes an application into small, independent services that communicate over APIs or message queues.

Question 2

In software testing, what does 'mutation testing' evaluate?

Accepted Answer

The effectiveness of a test suite by introducing small code changes

Answer

Mutation testing introduces small syntactic changes (mutants) to source code and checks whether existing tests detect those changes.

Question 3

What is the primary purpose of a software architecture's 'quality attribute utility tree' in the ATAM method?

Accepted Answer

To prioritize and refine quality attribute scenarios for architectural evaluation

Answer

The utility tree in ATAM structures and prioritizes quality attributes (e.g., performance, security) into concrete, testable scenarios.

Question 4

Which concurrency model does Go (Golang) use to avoid shared-state race conditions?

Accepted Answer

Communicating Sequential Processes (CSP) with goroutines and channels

Answer

Go implements CSP, where goroutines communicate by passing messages through channels rather than sharing memory.

Question 5

In database systems, what anomaly does the SERIALIZABLE isolation level prevent that READ COMMITTED does not?

Accepted Answer

Phantom reads

Answer

SERIALIZABLE prevents phantom reads — new rows inserted by concurrent transactions becoming visible within the same transaction — which READ COMMITTED allows.
