Derivative Classification Training Practice Exam

The concept of "revealed by" pertains specifically to classified information that is identified through analysis and interpretation of existing information, rather than directly disclosed in a straightforward manner. This means that certain conclusions or bits of classified content can be deduced from non-classified or previously disseminated information. The ability to extract or infer classified data through thoughtful analysis emphasizes the importance of understanding the implications of what is known and how it can suggest additional classified insights. In contrast, the other options do not align with this definition of "revealed by." Public knowledge does not offer any classification status or requirements for assessment. Clearly stated classified content does not require analysis to determine its classification—it is already classified. Similarly, information that simply requires confirmation does not imply that it has been analyzed or deduced; rather, it suggests a need for validation of its classification status. Thus, the focus on deduction through analysis makes the reference to classified information particularly relevant.
