Unit 6 · Software Engineering Paper 2 CS · June 2023

Consider the following statements about a software product line system:
Statement I: At the interaction level, components provide an operator display interface and an interface with the communication system used.
Statement II: At the I/O management level, components handle operator authentication, report generator and query manager.

Pick an option to check yourself, or open the answer below.

Show answer & explanation

Correct answer: A. Both Statement I and Statement II are correct

Explanation

In the generic layered architecture used for product-line resource-management systems, the interaction level is responsible for the operator-facing display and for interfacing with other communicating systems, exactly as Statement I describes. The I/O management level sits just below it and is responsible for operator authentication along with report-generation and query-management components, matching Statement II. Both statements correctly describe their respective architectural levels, so both are correct, option (i).
