CEC Website Development & User Experience 4

Question 1

What is the purpose of implementing a Content Delivery Network (CDN) for an ecommerce website?

Accepted Answer

Serve static assets from servers geographically close to users to reduce latency

Answer

A CDN caches static files (images, CSS, JS) at edge nodes worldwide so users download assets from the nearest location, reducing load time.

Question 2

Which UX pattern helps users understand where they are within a deep product category hierarchy on an ecommerce site?

Accepted Answer

Breadcrumb navigation

Answer

Breadcrumbs display the user's current location path (e.g., Home > Electronics > Laptops > Gaming), aiding navigation and reducing disorientation.

Question 3

An ecommerce site experiences high bounce rates on its homepage. Which metric would best help diagnose whether slow load time is the primary cause?

Accepted Answer

Time to Interactive (TTI) and Largest Contentful Paint (LCP)

Answer

TTI and LCP directly measure perceived and actual load performance, helping diagnose whether speed is driving users to leave before engaging.

Question 4

What is progressive disclosure in ecommerce UX design?

Accepted Answer

Revealing additional information or options only when the user needs them

Answer

Progressive disclosure reduces cognitive load by hiding advanced options or secondary information until users explicitly request them.

Question 5

Which ecommerce personalization technique uses collaborative filtering to recommend products?

Accepted Answer

'Customers who bought this also bought' recommendations based on purchase patterns

Answer

Collaborative filtering identifies patterns across many users' purchase histories to recommend items that similar customers also bought.
