Which of the following is a requirement of DFARS?

The correct answer is that DFARS contains requirements of law and DoD-wide policies. The Defense Federal Acquisition Regulation Supplement (DFARS) is a set of regulations specifically designed to govern the procurement processes of the Department of Defense (DoD). It supplements the Federal Acquisition Regulation (FAR) and includes specific legal requirements and policies that apply to DoD acquisitions. This means that DFARS sets mandatory rules and guidelines that contracting officers and agencies must follow to ensure compliance with federal law and to align with DoD objectives.

The other options do not accurately reflect the nature of DFARS. It is not limited to civilian agencies; instead, it is specifically aimed at defense-related procurement. Furthermore, DFARS is not an optional guideline; it establishes binding requirements that must be adhered to. Finally, it does not regulate only international contracts; it covers a broad range of contracts related to defense at all levels, including domestic contracts.
