CV0-004 Practice Question: Use a public cloud to host a static website with…
A company plans to use a public cloud to host a static website with minimal configuration. The website content is stored in an object storage bucket. Users access the site via a custom domain name. Which cloud service should the company use to serve the content with low latency globally?
⚠ Common exam trap
CompTIA often tests the misconception that a load balancer or DNS round-robin alone can provide global low-latency delivery, when in fact they lack caching and edge distribution, which are essential for static content performance.
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) with the object storage as origin
A CDN caches static content at edge locations worldwide, reducing latency for global users. By configuring the object storage bucket as the origin, the CDN pulls content on cache miss and serves it from the nearest edge node. This meets the requirement of minimal configuration while providing low-latency delivery via a custom domain.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reverse proxy server in each region
Why it's wrong here
A reverse proxy per region requires provisioning and managing compute instances, contradicting the minimal-configuration requirement, and caches only within that region. It is tempting because reverse proxies do cache and terminate TLS, but a CDN provides this globally without infrastructure management.
- ✗
DNS-based round-robin to multiple storage buckets
Why it's wrong here
Round-robin DNS distributes requests across buckets but provides no caching or edge termination, so every user still fetches objects from origin storage, adding latency. It is tempting as a cheap multi-region distribution method, yet a CDN is the service designed to cache content at edge locations.
- ✗
Load balancer distributing traffic to multiple object storage endpoints
Why it's wrong here
A load balancer distributes connections across storage endpoints but does not cache content at edge locations, so latency to origin remains. It is tempting because load balancers improve availability and spread traffic, yet global low-latency static delivery requires CDN edge caching.
- ✓
Content delivery network (CDN) with the object storage as origin
Why this is correct
A CDN caches the bucket's objects at globally distributed edge locations, so users fetch content from the nearest point of presence rather than the origin region. This directly satisfies the low-latency global access requirement while the object storage remains the origin, and it needs minimal configuration compared with running compute or a web server.
