Question 1
IntermediateAnalytics in the Adobe Experience Cloud Ecosystem · Experience Cloud ID Service (ECID) architecture
A multinational corporation is implementing Adobe Analytics across multiple distinct top-level domains (e.g., brand-a.com and brand-b.com). They want to track visitors seamlessly across both domains using the Experience Cloud ID (ECID) service. Which mechanism allows the ECID to persist when a user navigates from brand-a.com to brand-b.com?
Answer and explanation
Correct answer: B
Browsers restrict cookies to the domain that set them. To share the ECID across different top-level domains, the appendVisitorIDsTo helper function must be used to pass the ECID via URL query parameters, allowing the destination domain's ECID service to read and store the same ID.
