CV0-004 Cloud Architecture and Design Practice Question
Which storage type is most suitable for hosting a shared file system accessible by multiple virtual machines in a cloud environment?
⚠ Common exam trap
The CV0-004 exam often tests the misconception that block storage can be shared by multiple VMs, but the trap here is that block storage is a single-attach device unless you implement a complex clustered file system (e.g., GFS2 or OCFS2), which is not the default or simplest solution for shared access.
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 (option D) is the correct choice because it provides a hierarchical, shared file system that multiple virtual machines can mount simultaneously using standard protocols like NFS (Network File System) or SMB/CIFS. This allows concurrent read/write access with file-level locking, making it ideal for shared workloads such as home directories, content management, or collaboration tools in a cloud environment.
