An enterprise application requires block storage with extremely high IOPS and ultra-low latency for an Oracle Database deployment. Which OCI Block Volume performance tier should you configure?

Trap 1: Lower Cost

Lower Cost is optimized for large sequential workloads or infrequent access storage.

Trap 2: Basic

Basic is designed for boot volumes and non-performance-critical workloads.

Trap 3: Balanced

Balanced is used for general-purpose workloads with moderate IOPS requirements.
