Oracle Cloud Infrastructure Foundations
Practice Test Exam
1. What is an OCI region?
A) A logical boundary inside a subnet
B) A localized geographic area that contains one or more
availability domains
C) A single physical server rack
D) A billing container for related services
Correct Answer: B
Rationale: A region is a localized geographic area, such as
Phoenix or Frankfurt, where OCI operates cloud resources. Each
region contains one or more availability domains .
2. What is an availability domain in OCI?
A) A set of IAM policies applied to a compartment
,B) One or more data centers within a region that are isolated
from each other
C) A private IP range inside a VCN
D) A grouping of resources that share a tag namespace
Correct Answer: B
Rationale: An availability domain is a fault-isolated location
within a region. By deploying across availability domains, you
reduce the chance that one data center issue affects your entire
application .
3. What is a fault domain?
A) A separate region
B) A grouping of hardware and infrastructure within an
availability domain, so instances in different fault domains do
not share a single point of failure
C) A network gateway
D) A billing unit
Correct Answer: B
,Rationale: Each AD has three fault domains, and distributing
instances across them protects against hardware failure and
maintenance within the AD. In a single-AD region, fault domains
are the only intra-region isolation available .
4. Why would you place compute instances in different fault
domains within the same availability domain?
A) To give them public IP addresses automatically
B) To reduce the impact of hardware or maintenance failures on
all instances at once
C) To avoid paying for block volumes
D) To enable cross-region replication
Correct Answer: B
Rationale: Fault domains are logical groupings of hardware and
infrastructure inside an availability domain. Spreading instances
across them helps protect against rack-level failures or planned
maintenance affecting all copies of a workload at the same time
.
, 5. Which OCI construct represents your organization's secure
top-level cloud account?
A) Compartment
B) Availability domain
C) Tenancy
D) Fault domain
Correct Answer: C
Rationale: A tenancy is the root container for an organization's
OCI resources, identities, and policies. Compartments sit inside
the tenancy, not the other way around .
6. What is the main reason to use compartments in OCI?
A) To increase internet bandwidth for a VCN
B) To organize resources and apply access controls to separate
teams or projects
C) To replace identity groups for user management
D) To convert a private subnet into a public subnet
