Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use client-side JavaScript to fetch data asynchronously
Using client-side JavaScript to fetch data asynchronously reduces server load by offloading processing to the client, improving page load times. Option A is wrong because adding more web API calls increases server requests, worsening performance. Option B is wrong because increasing CDN cache duration only helps static content, not dynamic data from custom Liquid templates. Option D is wrong because disabling page caching forces the server to regenerate every request, increasing load.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add more web API calls to fetch data in parallel
Why it's wrong here
More API calls increase network overhead and processing.
- ✗
Increase the CDN cache duration for all pages
Why it's wrong here
CDN caching helps static assets but not dynamic pages with Liquid.
- ✓
Use client-side JavaScript to fetch data asynchronously
Why this is correct
Client-side rendering reduces server load and improves perceived performance.
- ✗
Disable page caching to ensure fresh data
Why it's wrong here
