1Z0-997-26 Workload Migration Practice Question
Your organization is migrating a high-throughput transactional database to OCI. During peak business hours, the database experiences massive I/O bursts. You want to ensure the underlying storage configuration can scale its IOPS independently of storage capacity. Which OCI block volume feature should you enable?
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
✓
OCI Block Volume Auto-Tune performance feature or manual VPU adjustment.
OCI Block Volume service allows users to dynamically adjust the Performance Units (VPUs) per GB independently of the storage capacity size, enabling high IOPS on demand.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
OCI Object Storage Infrequent Access tier
Why it's wrong here
Object storage tiers are for unstructured object data, not relational block database volumes.
- ✗
OCI File Storage Service snapshot policies
Why it's wrong here
Snapshots manage backup points, not IOPS performance scaling.
- ✗
OCI Local NVMe RAID striping
Why it's wrong here
While local NVMe is fast, it is ephemeral storage, not configurable block volume performance units.
- ✓
OCI Block Volume Auto-Tune performance feature or manual VPU adjustment.
Why this is correct
Auto-tune or manual VPU scaling allows block volumes to dynamically increase IOPS and throughput without needing to increase volume size.
