OCI INTRO Exam Flashcards
Which capability can be used to protect against failures within an OCI availability domain?
Fault Domain
What is true about regions and availability domains
An OCI region has one or more availability domains
composed of one or more isolated, interconnected availability domains. Each availability domain is a separate physical location within a region. The number of availability domains per region may vary; some OCI regions have three availability domains, while some others have a single availability domain.
OCI Region
a subdivision of an availability domain
Fault Domain
Each availability domain contains “ “ fault domains.
three
let you distribute your instances so that they are not on the same physical hardware within a single availability domain.
Fault Domain
A fault domain cannot be associated with
multiple availability domains.
share infrastructure
power, cooling, networking within a region
availability domain
An availability domain is one or more data centers located within a
region
Localized geographic area
Region
In this scenario, distributing the servers and database nodes across different fault domains within the same availability domain would provide protection against the failure of a single fault domain. If one fault domain experiences a failure, the other would remain unaffected, ensuring the high availability of the application.
Place one server and DB in one fault domain
Place second server and DB in another fault domain.
a service that provides a portable, ruggedized device running a subset of OCI services, designed for deployment in the field outside of a traditional data center. It is not a service specifically designed for multicloud deployment.
Oracle Roving Edge Infrastructure
designed to allow Oracle Cloud Infrastructure to interoperate with Azure, indicating a multicloud approach
Oracle Database Service for Azure and Oracle Interconnect for Azure
analytics service for MySQL Database service that runs on AWS but the account management and billing and metering are done through OCI
Oracle MySQL Heatwave
What is anti-affinity within a fault domain?
Each fault domain runs on its own set of physical hardware, so a failure that impacts one fault domain does not affect instances in other fault domains.
