• Understanding top audience attributes of those exposed to Amazon DSP campaigns
• Attribution of on-Amazon conversion events to Amazon Ads media events
• Understanding the overlap of those exposed to Amazon DSP campaigns and those exposed to sponsored ads campaigns
• Attribution of offline conversion events to Amazon Ads media events

The correct answer is: Attribution of offline conversion events to Amazon Ads media events

Explanation: When you use Amazon Ads events in conjunction with first-party inputs, you can attribute offline conversion events to Amazon Ads media events. This allows you to join your own sales, CRM, or customer data (containing supported joinable identifiers) to Amazon advertising events like impressions and clicks, so you can measure the influence of Amazon Ads on conversions that happen outside Amazon.com (e.g., in your D2C store, in offline retail, or via another channel).

Reference content: From Amazon’s official documentation (How AMC works):

“You can bring in your own customizable datasets … containing supported identifiers [and] join with AMC data to attribute off-Amazon events (purchases, sign-ups, store visits etc.) to Amazon advertising events such as impressions and clicks.”
