What are the three primary considerations for defining system boundaries? Response:

A fundamental consideration when defining system boundaries is that the components within the boundary are typically under the same direct management control. This criterion helps delineate which assets and operations are consistently governed by the same security policies and processes, simplifying risk management and oversight.

System components being "abnormally" under the same direct management control is not a standard or logical consideration for defining boundaries.

Components being under "indirect" management control suggests a less unified approach to security, which complicates boundary definition and direct security responsibility.

This choice is identical to A in its provided text and therefore represents the same correct consideration for defining system boundaries.
