System Architecture & Design Flashcards

Which tool in a tag manager lets you test changes without publishing them to live visitors?

Answer: Preview/debug mode

Preview mode shows which tags fire in a private session before publishing.

Why is it good practice to define a naming convention for events and parameters?

Answer: It keeps data consistent, discoverable, and easier to analyze at scale

Consistent naming avoids fragmented, duplicate, or ambiguous events in reporting.

What is a measurement plan (or tracking specification) used for?

Answer: Documenting business goals, KPIs, and the events/data needed to measure them

It links business objectives to the specific data points and implementation required.

Which method is best for validating that analytics hits reach the collection endpoint correctly?

Answer: Inspecting network requests in browser developer tools or a debug view

Network inspection confirms the request fires with the expected parameters and status.

Which architecture element reduces latency by serving tracking scripts from locations close to users?

Answer: A content delivery network (CDN)

CDNs cache static scripts at edge locations to deliver them faster.

Data retention settings in an analytics platform determine:

Answer: How long user-level event data is kept before automatic deletion

Retention controls how long granular user and event data is stored, affecting explorations and compliance.

When hits arrive from a bot that executes JavaScript, which approach best protects data quality?

Answer: Apply bot filtering plus server-side or behavioral rules to exclude suspicious traffic

Sophisticated bots run scripts, so layered filtering using known lists and behavioral signals is needed.
