System Architecture & Design Flashcards

What is cross-domain tracking designed to preserve?

Answer: A single user's session and identity as they move between your owned domains

It passes the client identifier between domains so one visit isn't split into separate sessions.

Which issue commonly appears in reports when cross-domain tracking is misconfigured?

Answer: Self-referrals from your own domains

Without linking, the second domain sees the first as a referral and starts a new session.

Which statement about consent management and analytics architecture is most accurate?

Answer: Tag firing should be conditioned on the user's consent state where required

Under privacy regulations, tags and storage must respect consent signals before firing.

Which feature of server-side tagging helps with data governance?

Answer: It lets you inspect, filter, or redact fields before forwarding to vendors

A server container gives control over what data each vendor ultimately receives.

What is a common trade-off of moving to server-side tagging?

Answer: Added infrastructure cost and maintenance

Running a server container requires hosting, monitoring, and cost that client-side setups avoid.

Which identifier approach is most resilient for recognizing logged-in users across devices?

Answer: A first-party user ID assigned at login

A login-based user ID persists across devices, unlike device-bound cookies.

A 'hit' in analytics architecture refers to:

Answer: A single interaction sent to the analytics server, such as a pageview or event

Hits are the individual data requests (pageview, event, transaction) that make up sessions.
