Cloud Digital Leader Fundamental cloud concepts Practice Question
This GCDL practice question tests your understanding of fundamental cloud concepts. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A small business wants to host a low-traffic website with a single-page application. They have limited budget and no IT staff. Which Google Cloud solution is most cost-effective and easy to manage?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Host the static files on Cloud Storage and use Cloud CDN
Option C is correct because hosting static files (HTML, CSS, JS) on Cloud Storage with Cloud CDN provides a serverless, highly scalable, and low-cost solution for a low-traffic single-page application. Cloud Storage serves static content directly without provisioning any virtual machines, and Cloud CDN caches content at edge locations to reduce latency and egress costs. This eliminates the need for any server management, making it ideal for a business with no IT staff.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use App Engine Standard Environment
Why it's wrong here
App Engine Standard is a managed platform but costs more for static content.
✗
Deploy a virtual machine on Compute Engine with a web server
Why it's wrong here
Managing a VM is complex and more expensive for a simple static site.
✓
Host the static files on Cloud Storage and use Cloud CDN
Why this is correct
Cloud Storage can host static websites with built-in CDN and no server management.

✗
Set up Google Kubernetes Engine cluster
Why it's wrong here
GKE adds unnecessary complexity and cost for a single-page application.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume a web server (Compute Engine) or a platform like App Engine is necessary for any website, overlooking that static hosting on Cloud Storage with CDN is the simplest and cheapest option for single-page applications.
Detailed technical explanation
How to think about this question
Cloud Storage serves static content via HTTP GET requests directly from a bucket configured for public access, and Cloud CDN uses Google's global edge network to cache responses based on Cache-Control headers (e.g., max-age=3600). A subtle behavior is that Cloud CDN does not automatically cache all content; you must set appropriate cache directives (e.g., public, max-age) on the objects, and for dynamic content like index.html, you may need to invalidate the cache after updates. In a real-world scenario, a small business could use a CI/CD pipeline (e.g., Cloud Build) to automatically upload new builds to the bucket, triggering a cache invalidation via the Cloud CDN API.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
