Google ACE Planning and Configuring a Cloud Solution Practice Question
A company needs to store and serve user-generated content such as images and videos. The data must be accessible globally with low latency. Which Google Cloud storage service should they 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
✓
Cloud Storage
Cloud Storage is object storage designed for global accessibility, with low-latency access and multiple storage classes. It supports serving content via CDN integration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Persistent Disk
Why it's wrong here
Persistent Disk is zonal block storage that must be attached to a single Compute Engine VM to be used. It is not a managed object store with a global HTTP/HTTPS endpoint, so it cannot directly serve user-generated content to end users. Persistent Disks also have availability limited to the zone where they reside, making them unsuitable for globally distributed content delivery without additional infrastructure such as load balancers and mirroring.
- ✗
Cloud Filestore
Why it's wrong here
Cloud Filestore is a managed NFS file server that provides POSIX-compliant file sharing primarily for Compute Engine and GKE workloads. It is not an object storage service, and files cannot be accessed via public HTTP URLs or served directly to internet users without running your own file-serving application. While Filestore can be regional or multi-regional, its access model is based on network file mounts, not on upload/download semantics required for user-generated content.
- ✓
Cloud Storage
Why this is correct
Cloud Storage is the correct choice because it is a durable, highly available object storage service with a global namespace and public HTTPS ingestion and serving endpoints. It provides strong consistency, configurable permissions, and can integrate with Cloud CDN for low-latency delivery of cached content, making it ideal for user-generated photos, videos, and documents. Lifecycle policies can cost-effectively archive older content, and resumable uploads support large files from mobile and web clients.
- ✗
Local SSD
Why it's wrong here
Local SSDs are ephemeral, physically attached SSDs that are tied to the lifecycle of a single Compute Engine VM; they cannot be detached, and data is permanently lost if the VM is stopped or deleted. They offer high throughput for local compute but provide no redundancy, no global accessibility, and no direct HTTP serving capability. Local SSDs are meant for temporary scratch space or caching, not for durable storage of user-generated content.
