An EU retailer uses purchase histories for personalized advertising solely on the basis of consent. A customer withdraws that consent. The retailer must still retain specified invoice data under an applicable tax law. How should it handle the customer's data now?
Correct answer: B - End the advertising use and retain only the invoice data needed to meet the tax obligation.
'Why was my application declined?' asks a loan applicant. The lender has disclosed its use of AI and keeps logs sufficient to reconstruct each assessment. Its reply, however, is, 'Your score did not meet our policy.' To address what is missing from that reply, the lender should provide:
Correct answer: C - The material factors that actually drove this applicant's result, explained in understandable language.
Before authorizing automatic fraud declines, a payment processor examines a fully verified test of 1,000 transactions. Of 80 fraudulent transactions, the model detected 60; it flagged 100 transactions in total. An executive cites 94% overall accuracy as reassurance. Which interpretation most directly describes the risk to customers whose payments would be declined?
Correct answer: D - Precision is 60%, so 40% of the proposed declines would affect legitimate transactions.
A tourism company obtains individual consent to record accounts of culturally significant sites from members of an Indigenous community. It proposes licensing the resulting dataset to commercial partners. The community's recognized governing body says it has not authorized that reuse. Under the CARE Principles for Indigenous Data Governance, whose interests remain unaddressed?
Correct answer: D - The community's collective interests and authority to govern reuse, which individual consent alone does not settle.
A UK game covered by the Children's Code lets players aged 14-17 actively choose to show their live location to friends. Sharing stays on after a player closes a session. There is no compelling child-interest reason for it to persist. Which revision corrects the defect while preserving the optional feature?
Correct answer: A - Make location visibility revert to off at each session's end, with a fresh choice before the next use.
'Most customers choose to share their shopping data,' says a retailer's checkout page. The majority figure describes loyalty-club members, a small minority of customers. Accepting and declining are equally easy. The ethics review focuses on the social-proof message. What change directly corrects its misleading implication?
Correct answer: A - Identify loyalty-club members as the population behind the claim, or remove the claim.
Procurement is reviewing a broker's offer of behavioral profiles for personalized pricing. The broker will indemnify the retailer if the data were improperly obtained, but has not documented how they were collected or which uses were permitted. Which evidence would address this gap rather than merely shift financial loss?
Correct answer: A - Records establishing data provenance and permission for the retailer's proposed pricing use.
Past promotion decisions are being used to train a firm's management-potential model. The records include every employee, but an old policy barred part-time staff from promotion regardless of performance. Balancing full-time and part-time representation has not removed the disadvantage. Which intervention targets the remaining source of bias?
Correct answer: D - Rebuild the target using validated job-relevant performance evidence instead of past promotion outcomes.
Immediately after a software update, a warehouse's automated dispatch system sends two vehicles into the same occupied loading lane. A supervisor prevents a collision and confirms that the conflicting instructions came from the system. A tested manual-dispatch procedure is available. What takes priority before the next vehicle is dispatched?
Correct answer: C - Suspend automated dispatch and activate the tested manual procedure while the fault is investigated.
A previously well-validated cancellation model now overestimates how many subscribers will leave. Engineers confirm that input definitions and the mix of usage patterns have not changed. Verified outcomes show that subscribers with the same usage patterns are now much more likely to renew than before. What best explains the deterioration?
Correct answer: B - Concept drift: the relationship between familiar usage patterns and subscription renewal has changed.
