1. The Wolfsberg Group. (2019). Guidance on Sanctions Screening. Page 11, Section 4.3, "Data". This section explicitly supports both correct answers:
For option B: "FIs should consider what data is relevant for screening and what data may be excluded (e.g. internal or suspense accounts, or certain types of government entities)."
For option E: "FIs should also consider whether certain data should be removed from screening on an ongoing basis once it is no longer relevant (e.g. a former address)."
2. The Wolfsberg Group. (2019). Guidance on Sanctions Screening. Page 12, Section 4.4, "Tuning". This section refutes options C and D:
For option C: "FIs may also use suppression lists (sometimes referred to as “good guy” lists) to automatically discount alerts against names that have been previously investigated and discounted as false positives."
For option D: The section discusses the importance of setting an "appropriate threshold" to balance effectiveness and efficiency, implying that moving away from an optimal level would be detrimental.
