INFRASTRUCTURE (OCI) ASSOCIATE (1Z0-
1085) EXAM BANK | COMPLETE EXAM
BANK WITH CORRECT ANSWERS AND
RATIONALES. A+ GRADED
1. Which Oracle Cloud Infrastructure service
provides a fully managed, scalable, and serverless
data warehouse for analytical queries?
A) Oracle Autonomous Data Warehouse (ADW)
B) Oracle Database Cloud Service (DBCS)
C) Oracle Exadata Cloud Service
D) Oracle Big Data Service
Correct answer: A
Rationale: Autonomous Data Warehouse (ADW) is a
self-driving, self-securing, self-repairing data
warehouse. DBCS is for transactional databases.
2. Which OCI compute service runs code in response
to events without provisioning servers?
A) Oracle Functions (serverless, Fn Project)
B) OCI Compute (VMs)
,C) OCI Container Engine for Kubernetes (OKE)
D) OCI Container Instances
Correct answer: A
Rationale: Oracle Functions is a serverless function-
as-a-service (FaaS) platform based on the Fn Project.
It scales automatically.
3. An administrator needs to create a virtual cloud
network (VCN) with a CIDR block of 10.0.0.0/16. How
many usable IP addresses does this provide?
A) 256
B) 65,536 (2^16)
C) 16,384
D) 65,534 (minus network and broadcast? OCI VCNs
do not reserve network/broadcast addresses)
Correct answer: B
Rationale: /16 provides 65,536 IP addresses. OCI
does not reserve network and broadcast addresses,
so all are usable.
4. Which OCI block storage offering provides the
highest IOPS (up to 1 million) for performance-
intensive workloads?
,A) Block Volume (Balanced)
B) Block Volume (Higher Performance)
C) Block Volume (Ultra High Performance)
D) Local NVMe (attached to high-performance
instances)
Correct answer: D (or C depending on instance type)
Rationale: Local NVMe provides up to 1 million IOPS
but is ephemeral. Block Volume Ultra High
Performance (UP) provides up to 400,000 IOPS.
5. Which OCI identity component is used to group
users and apply permissions collectively?
A) Policy
B) Dynamic Group
C) Group
D) Compartment
Correct answer: C
Rationale: Groups contain users. Policies grant
permissions to groups (or dynamic groups) at
specific compartments or tenancy level.
6. A company wants to connect its on-premises
network to OCI using a private, dedicated, high-
, bandwidth connection. Which service should be
used?
A) FastConnect
B) VPN Connect (IPsec)
C) Virtual Cloud Network (VCN)
D) Internet Gateway
Correct answer: A
Rationale: FastConnect provides private dedicated
physical connections (up to 100 Gbps) to OCI. VPN
Connect uses the public internet.
7. Which OCI storage service provides a fully
managed, POSIX-compliant file system accessible
from multiple compute instances?
A) File Storage (FSS)
B) Block Volume
C) Object Storage
D) Archive Storage
Correct answer: A
Rationale: OCI File Storage Service (FSS) is a
managed NFS file system (shared across instances).
Block Volume is block storage.
