CV0-004 Cloud Architecture and Design Practice Question
Which of the following storage types is most suitable for hosting a shared file system that multiple virtual machines need to access concurrently using NFS?
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
✓
File storage
File storage (e.g., EFS, Azure Files) provides a shared file system accessible via NFS or SMB.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Archive storage
Why it's wrong here
Archive storage is a low-cost tier for infrequently accessed data with retrieval latency measured in hours; it cannot serve concurrent NFS mounts. It is tempting because it is cheap and durable for long-term retention, but the scenario needs live, low-latency shared file access, which archive tiers cannot deliver.
- ✓
File storage
Why this is correct
File storage exposes SMB or NFS shares, letting multiple VMs mount the same file system concurrently. Block storage attaches to a single instance, and object storage lacks a POSIX NFS interface. NFS concurrency is therefore satisfied only by file storage.
- ✗
Block storage
Why it's wrong here
Block storage presents raw volumes to a single host at a time; concurrent NFS mounts from multiple VMs require a shared file system layer, which block volumes do not provide. Block storage is correct for a single VM's boot disk or database volume, making it tempting, but it cannot serve concurrent NFS clients.
- ✗
Object storage
Why it's wrong here
Object storage exposes an HTTP API for whole-object reads and writes; it does not implement NFS or POSIX file semantics, so VMs cannot mount it as a shared file system. Object storage suits backups and static content, which makes it tempting, but NFS requires a file-level protocol it does not offer.
