Final answer:
The OCI Fault Domain provides fault tolerance and high availability for resources within the Oracle Cloud Infrastructure.
Step-by-step explanation:
The OCI Fault Domain provides fault tolerance and high availability for resources within the Oracle Cloud Infrastructure. It is designed to ensure that your applications and services remain accessible even in the event of a failure. Fault domains are essentially groups of hardware and infrastructure within a data center that are isolated from each other.
In the event of a fault or maintenance activity within a fault domain, Oracle automatically fails over resources to healthy hardware in another fault domain, ensuring continuity and minimizing disruption.
