OCI Foundations Certification
1. What is the primary benefit of using Oracle Cloud Infrastructure (OCI) over
traditional on-premises environments?
A. Lower latency due to localized data centers
B. Higher cost and complexity
C. On-demand scalability and cost efficiency
D. Limited access to global resources
✅ Correct Answer: C. On-demand scalability and cost efficiency
💡 Explanation:
OCI provides flexible scaling and a pay-as-you-go model, reducing operational costs compared
to traditional data centers.
2. Which OCI service is used to store unstructured data such as images, videos,
and backups?
A. Oracle Cloud VMware Solution
B. OCI Block Storage
C. OCI Object Storage
D. OCI Compute
✅ Correct Answer: C. OCI Object Storage
💡 Explanation:
OCI Object Storage is designed for scalable, durable, and high-performance storage of
unstructured data.
3. What is the default security feature that restricts access to OCI resources?
A. Virtual Cloud Network (VCN)
B. Security Lists
C. Identity and Access Management (IAM) Policies
D. Availability Domains
✅ Correct Answer: C. Identity and Access Management (IAM) Policies
,💡 Explanation:
IAM policies control who can access OCI resources and what actions they can perform.
4. What is an Availability Domain in OCI?
A. A physical data center within a region
B. A backup location for disaster recovery
C. A logical grouping of network components
D. A separate cloud environment for development
✅ Correct Answer: A. A physical data center within a region
💡 Explanation:
An Availability Domain (AD) is a fault-isolated data center within an OCI Region, providing
high availability and redundancy.
5. How does OCI ensure high availability and disaster recovery?
A. By providing multiple Fault Domains within an Availability Domain
B. By using a single data center for all workloads
C. By limiting scalability options
D. By storing data only in one physical location
✅ Correct Answer: A. By providing multiple Fault Domains within an Availability
Domain
💡 Explanation:
Fault Domains help distribute workloads across multiple isolated environments, minimizing
the impact of hardware failures.
6. What is the primary purpose of an OCI Virtual Cloud Network (VCN)?
A. To connect on-premises data centers with Oracle Cloud
B. To create an isolated, secure network for cloud resources
C. To manage user access to the OCI Console
D. To store large amounts of structured data
✅ Correct Answer: B. To create an isolated, secure network for cloud resources
, 💡 Explanation:
A VCN acts as a private network in OCI, allowing users to define subnets, security rules, and
routing.
7. Which feature allows you to control inbound and outbound traffic in an OCI
VCN?
A. Availability Domains
B. Security Lists and Network Security Groups (NSGs)
C. Compute Instances
D. Object Storage Buckets
✅ Correct Answer: B. Security Lists and Network Security Groups (NSGs)
💡 Explanation:
Security Lists and NSGs define firewall rules to restrict or allow network traffic within a
VCN.
8. What is the key advantage of using OCI Compute Autoscaling?
A. It allows manual scaling of instances only
B. It automatically adjusts compute resources based on demand
C. It permanently increases the instance size
D. It prevents resources from scaling up
✅ Correct Answer: B. It automatically adjusts compute resources based on demand
💡 Explanation:
OCI Compute Autoscaling ensures optimal performance by dynamically adding or removing
compute instances based on workload needs.
9. Which OCI database service provides a fully managed, autonomous database
solution?
A. Oracle Database Cloud Service (DBCS)
B. MySQL Database Service
C. Autonomous Database (ADB)
D. Bare Metal Database
