CV0-004 Cloud Architecture and Design Practice Question
A company is deploying a global web application and wants to reduce latency for users around the world. The application serves static content (images, CSS) and dynamic API responses. Which combination of services should the architect use?
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
✓
CDN for static content and a global load balancer with latency-based routing for dynamic content
CDN caches static content at edge locations, reducing latency. For dynamic content, a global load balancer with latency-based routing directs users to the closest region. DNS alone cannot reduce latency for dynamic content. A single load balancer does not provide global distribution.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
CDN for static content and a global load balancer with latency-based routing for dynamic content
Why this is correct
CDN reduces latency for static files; latency-based routing directs dynamic requests to the nearest region.
- ✗
CDN for all content without backend routing
Why it's wrong here
CDN cannot serve dynamic API responses efficiently; it needs to pull from origin.
- ✗
A single load balancer in one region with a CDN
Why it's wrong here
A single region does not reduce latency for global users.
- ✗
DNS round-robin for both static and dynamic content
Why it's wrong here
DNS round-robin does not consider latency and does not cache content.
