Explanation
NOTE: The listed correct answer (D - Interconnection Security Agreement) appears to be incorrect for this scenario. An ISA governs the technical and security controls required when two organizations directly interconnect their IT systems or networks - it is about system-to-system connectivity requirements, not about general information-sharing arrangements. A Memorandum of Understanding (MOU) (B) is the most appropriate document here: it is a non-binding agreement that formally documents the intent, scope, and terms of cooperation between parties. Because the two organizations are competitors, an MOU allows them to define what threat intelligence will be shared and how, without implying a formal business partnership or requiring direct network integration. A BPA (A) implies a deeper commercial relationship, an SLA (C) defines measurable service delivery obligations, and an ISA (D) would only apply if they were directly connecting their networks. The correct answer should be B.
