Are events logged at the presentation tier good places to find evidence related to application domain specific logic?

• A. True
• B. False
• C. Sometimes
• D. Not sure

Answer: (B)

Events logged at the presentation tier are not reliable evidence of application domain-specific logic because the presentation layer focuses on UI and user interactions, not the business rules that govern data and processes. The domain logic is implemented in the application or service layer, and its evidence usually appears in server-side logs, audit trails, and database transaction records that capture decisions, state changes, validations, and data mutations. Presentation-tier logs can help reconstruct a timeline of what a user did, but they rarely reveal why a decision was made or what rules were applied, and they can be incomplete or subject to client-side tampering. So, while UI logs can supplement an investigation, they aren’t the best primary source for domain-specific logic; server-side logs and related records provide more authoritative evidence.
