CV0-004 Cloud Architecture and Design Practice Question
A company is deploying a global web application that serves static content (images, CSS, JavaScript) to users worldwide. They want to reduce latency and offload traffic from the origin servers. Which service should they implement?
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
✓
Content Delivery Network (CDN)
A Content Delivery Network (CDN) caches static content at edge locations worldwide, reducing latency and offloading origin servers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Auto-scaling group
Why it's wrong here
An auto-scaling group adjusts compute capacity in response to demand; it neither caches static assets nor serves them from edge locations, so origin traffic and global latency remain unchanged. It is tempting as a general availability measure, and it would be correct for handling variable traffic volumes on the application tier.
- ✗
VPN connection
Why it's wrong here
A VPN connection provides encrypted private connectivity between networks; it does not cache or distribute static content to global users. It is tempting because it is a common networking component in cloud architectures, and it would be correct for giving remote staff or branch offices secure access to private resources.
- ✗
Load balancer
Why it's wrong here
A load balancer distributes requests across origin targets but does not cache static content or serve it from edge locations, so latency for worldwide users is unchanged. It is tempting because it does offload traffic from individual servers, and it would be correct for spreading dynamic requests across multiple healthy backends.
- ✓
Content Delivery Network (CDN)
Why this is correct
CDN caches content at edge locations, reducing latency.
