Question
What capability protects against failures within an OCI Availability Domain?
A. Fault Domain.
B. Object Storage.
C. Compartment.
D. Tenancy.
Answer
A. Fault Domain.
Explanation
A Fault Domain is a grouping of hardware and infrastructure within a single OCI Availability Domain that provides protection against failures. Each Availability Domain contains three distinct Fault Domains that do not share the same physical hardware, rack, power distribution, or network switches. By placing instances or databases across multiple Fault Domains, you ensure that if an unexpected hardware failure or planned maintenance event takes down one Fault Domain, the resources in the other Fault Domains remain online and operational.
