1Z0-1072-26 Storage Practice Question
An application running on an OCI compute instance needs to share a POSIX-compliant file system concurrently across multiple compute instances residing in different subnets of the same VCN. Which storage service is best suited for this requirement?
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 Service
File Storage Service (FSS) provides a durable, scalable, enterprise-grade network file system that can be accessed concurrently by thousands of compute instances using the standard NFS v3.0 protocol across availability domains and subnets within a VCN.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Block Volume
Why it's wrong here
Block volumes can only be attached to a single compute instance at a time (unless configured as a cluster volume under specific multi-attach settings, but FSS is the native multi-instance shared filesystem).
- ✗
Object Storage
Why it's wrong here
Object Storage is accessed via REST APIs, not through a POSIX-compliant file system mount.
- ✓
File Storage Service
Why this is correct
FSS natively supports concurrent NFS connections from multiple compute instances across the VCN.
- ✗
Local NVMe
Why it's wrong here
Local NVMe storage is ephemeral hardware directly attached to a specific compute host and cannot be shared across instances.
