Events, Forms & Navigation: Recap And Verify

5 questions. Answer all of them, then submit; you need 4 of 5 to pass.

1. 1. A single-page app changes routes with pushState, so no new page loads happen. Pageview tracking shows one page per visit. Which trigger fixes it?

   A DOM Ready trigger, which fires on every route changeThe History Change trigger, which fires on pushState navigationsA Timer trigger approximating one pageview per 30 secondsA Custom Event trigger on gtm.load
2. 2. Content arrives after an async fetch, and the site pushes content_loaded when it resolves. Why trigger on that push instead of the click that started the request?

   Click triggers cannot carry parametersThe click fires before the request resolves, so you would count loads that failed or never finishedCustom Event triggers are faster than click triggersGTM blocks click triggers during network requests
3. 3. You want form_start to fire once when a visitor first interacts with a form, and form_submit on submission. What does form_start tell you that form_submit cannot?

   How many visitors began the form but abandoned it before submittingWhich field the visitor filled in lastWhether the submission reached the serverThe visitor's input values
4. 4. You need start, progress and complete events for a native HTML5 <video> element. Why not use the YouTube Video trigger?

   The YouTube trigger only reports completions, not progressIt works, but requires the Video built-in variablesThe YouTube Video trigger only hooks YouTube's embedded player; native video needs its media events pushed to the dataLayerNative video cannot be tracked from GTM at all
5. 5. A checkout wizard has four steps and you want to see where people drop off. What is the cleanest event design?

   Four differently named events like step_one, step_two, step_three, step_fourOne form_step event pushed at each step, with a step parameter you read in a Data Layer VariableA Scroll Depth trigger, since later steps are further downOne form_submit event at the end; drop-off can be inferred
