OCI Foundation Course Study Guide questions with
correct answers
Which statement about OCI is NOT true?
- An availability domain is one or more data centers located within a
region.
- A single fault domain can be associated with multiple availability
domains within a region.
- Availability domains do not share infrastructure, such as power,
cooling, or network, within a region.
- An OCI region is a localized geographic area. Correct Answer-- A
single fault domain can be associated with multiple availability domains
within a region.
A fault domain is a subdivision of an availability domain. Each
availability domain contains three fault domains. Fault domains let you
distribute your instances so that they are not on the same physical
hardware within a single availability domain. A fault domain cannot be
associated with multiple availability domains.
Which Oracle Cloud Infrastructure service is NOT intended for a
multicloud solution?
- Oracle Roving Edge Infrastructure
- Oracle Interconnect for Azure
- Oracle MySQL Heatwave on AWS
,- Oracle Database Service for Azure Correct Answer-- Oracle Roving
Edge Infrastructure
Oracle Roving Edge Infrastructure is 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. On the other
hand, services like Oracle Database Service for Azure and Oracle
Interconnect for Azure are designed to allow Oracle Cloud Infrastructure
to interoperate with Azure, indicating a multicloud approach. Oracle
MySQL HeatWave is an analytics service for MySQL Database service
that runs on AWS but the account management and billing and metering
are done through OCI.
Which capability can be used to protect against failures within an OCI
availability domain?
- Load Balancer
- Compartments
- Regions
- Fault Domain Correct Answer-- Fault Domain
Fault domains provide a capability to protect your applications and
instances from unexpected hardware failures or network outages within
an availability domain. They provide anti-affinity: 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.
, You have subscribed to an OCI region that has one availability domain.
You want to deploy a highly available application with two servers and a
2-node database. How would you place the components to maintain the
high availability of the application?
- Place all the components in the same fault domain.
- Place the servers in one fault domain and the database nodes in another
fault domain.
- Place one server and a DB node in one fault domain, and the second
server and DB node in another fault domain.
- High availability is not possible as there is only one availability
domain in the region. Correct Answer-- Place one server and a DB node
in one fault domain, and the second server and DB node in another fault
domain.
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.
Which statement about regions and availability domains is true?
- All OCI regions have three availability domains.
- Fault domains provide protection against failures across regions.
- All OCI regions have a single availability domain.
