PDE Storing the Data Practice Question
A media company stores video files in a Cloud Storage bucket and wants to serve them to users through a custom domain over HTTPS. The files are not sensitive, but the company wants to reduce egress cost and latency for users distributed globally. The company also wants to avoid managing SSL certificates manually. What should the data engineer recommend?
⚠ Common exam trap
The trap here is focusing on storage class or access control features, which affect cost and permissions but do nothing for global delivery latency or custom domain HTTPS.

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
✓
Create a Cloud CDN backend bucket with the Cloud Storage bucket as the origin and enable Google-managed SSL certificates on the load balancer.
Cloud CDN with a backend bucket caches video content at Google's edge locations, lowering latency and egress for global users. Pairing it with a global external Application Load Balancer and Google-managed SSL certificates delivers HTTPS on a custom domain without the operational burden of managing certificates.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create a Cloud CDN backend bucket with the Cloud Storage bucket as the origin and enable Google-managed SSL certificates on the load balancer.
Why this is correct
Cloud CDN caches content at edge locations, reducing latency and egress cost for globally distributed users. Using a backend bucket with the Cloud Storage bucket as origin, combined with a global external Application Load Balancer and Google-managed certificates, provides HTTPS on a custom domain without manual certificate management.
- ✗
Enable Object Versioning on the bucket and configure a lifecycle rule to move objects to Nearline after 30 days.
Why it's wrong here
Object Versioning and lifecycle rules manage object history and storage cost; they have no effect on how content is delivered to users. Nearline also has a 30-day minimum storage duration and retrieval costs, which could increase cost for frequently accessed videos. Neither feature provides CDN caching or custom domain HTTPS.
- ✗
Set the bucket's default storage class to Standard and enable uniform bucket-level access.
Why it's wrong here
Storage class and uniform bucket-level access affect cost and permission evaluation, not delivery latency or egress. They do not provide a custom domain over HTTPS or caching at the edge. This configuration leaves users fetching objects directly from the bucket region, which increases latency for distant users and does not address certificate management.
- ✗
Generate signed URLs for each video and distribute them to users through the application.
Why it's wrong here
Signed URLs grant time-limited access to specific objects but do not cache content at the edge, so latency and egress remain unchanged. They also expire, requiring the application to regenerate them, and they do not provide a custom domain or automatic SSL. This approach solves access control, not global delivery performance.
