Question 1

What is the minimum OCPU allocation required when configuring an OCI Ampere A1 Compute flexible shape (VM.Standard.A1.Flex)?

Accepted Answer

1 OCPU. The OCI Ampere A1 Compute flexible shape (VM.Standard.A1.Flex) allows you to configure as little as 1 OCPU. This is the minimum because the shape is designed for granular, flexible allocation, and Oracle's documentation explicitly states that the minimum OCPU per instance is 1. Therefore, 1 OCPU is the correct answer.

Answer

4 OCPUs

Answer

2 OCPUs

Answer

8 OCPUs

Question 2

Which TWO of the following statements regarding OCI Instance Configurations and Instance Pools are correct? (Choose two.)

Accepted Answer

An instance configuration defines the blueprint (shape, image, metadata) used to provision instances in an instance pool.. Instance configurations act as templates for creating instance pools, and instance pools can be scaled manually or automatically via autoscaling configurations.

Answer

Instance configurations can only be created from scratch using JSON templates, never from an existing running instance.

Answer

Instance pools can only contain instances of different shapes and operating systems.

Answer

Autoscaling policies cannot be attached to instance pools.

Question 3

Which utility is used to authenticate and push custom container images built for OCI Functions to the Oracle Registry (OCIR)?

Accepted Answer

Docker CLI. Custom OCI Functions images are built as Docker images and pushed to OCIR using the Docker CLI after authenticating with `docker login <region>.ocir.io` using an OCI auth token. The Docker CLI is the standard tool for building, tagging, and pushing container images to any OCI-compliant registry, including OCIR.

Answer

VCN Management Console

Answer

Terraform CLI

Answer

OCI Object Storage CLI

Question 4

What is the primary purpose of OCI Compute Instance Launch Options?

Accepted Answer

To configure instance network virtualization, firmware type, and boot parameters.. OCI Compute Instance Launch Options control low-level platform settings applied at launch, including network virtualization type (paravirtualized vs. SR-IOV), firmware type (BIOS vs. UEFI), boot parameters, and secure boot/measured boot settings. These options affect how the hypervisor presents hardware to the guest and how the instance boots.

Answer

To set up automatic IAM user credential rotation.

Answer

To schedule automated block volume backup retention policies.

Answer

To define DNS domain suffix forwarding rules for VCN resolvers.

Question 5

What is the primary purpose of OCI compartments?

Accepted Answer

To organize and isolate cloud resources for security, access control, and billing management.. Compartments are logical containers used to organize and isolate OCI resources. They enable fine-grained access control via IAM policies, simplify billing by allowing cost tracking per compartment, and provide a security boundary for resources. This matches option D exactly.

Answer

To replace Virtual Cloud Networks for internal subnetting.

Answer

To isolate physical data center hardware for specific customers.

Answer

To automatically replicate data across multiple OCI regions for disaster recovery.

Question 6

An administrator needs to allow a group of developers to create and manage File Storage Service (FSS) file systems and mount targets in a compartment named 'FSCompartment'. Which policy statement is correct?

Accepted Answer

Allow group Developers to manage file-storage-family in compartment FSCompartment. File Storage Service resources (file systems, mount targets, snapshots, replication) are all members of the 'file-storage-family' aggregate resource type in OCI IAM. Granting 'manage file-storage-family' in the target compartment gives the Developers group full lifecycle control over FSS resources there, which is exactly what the administrator needs.

Answer

Allow group Developers to read storage-systems in tenancy

Answer

Allow group Developers to manage mount-targets in compartment FSCompartment

Answer

Allow group Developers to use nfs-shares in compartment FSCompartment

Question 7

You are configuring an OCI Public Load Balancer to distribute incoming HTTP traffic to backend compute instances. Which backend set configuration is required to verify the health of the instances?

Accepted Answer

Health check policy defining protocol, port, and optional URL path. Load balancer health checks regularly probe backend servers using specific protocols, ports, and paths to verify that instances are available and healthy.

Answer

A NAT Gateway attached to the backend server subnet

Answer

A security list allowing all incoming traffic from the internet

Answer

An active Service Gateway

Question 8

An administrator wants to allow a group of developers to view and manage Event Service rules and notifications. Which resource types should be used in the IAM policy?

Accepted Answer

Allow group DevOps to manage events, notifications in compartment AppComp. The OCI Events service and Notifications service use 'events' and 'notifications' as their resource types.

Answer

Allow group DevOps to use pub-sub in compartment AppComp

Answer

Allow group DevOps to manage messaging-family in tenancy

Answer

Allow group DevOps to inspect triggers in compartment AppComp

Question 9

What is the primary function of an OCI Internet Gateway?

Accepted Answer

To provide bi-directional communication between a VCN and the public internet for public subnets.. An Internet Gateway provides a path for bi-directional communication between your VCN and the public internet.

Answer

To provide private access to regional Oracle Object Storage.

Answer

To connect on-premises datacenters to OCI over dedicated circuits.

Answer

To route traffic between two VCNs in the same region.

Question 10

Which THREE components are required when configuring an OCI FastConnect direct peering connection?

Accepted Answer

Physical cross-connect or partner provider connection. A FastConnect direct peering connection requires a Dynamic Routing Gateway (DRG) attached to your VCN, a FastConnect virtual circuit, and a physical cross-connect or partner connection setup.

Answer

Internet Gateway

Answer

Local Peering Gateway (LPG)
