Accepted Answer

OCI Cloud@Customer. OCI Cloud@Customer brings specific OCI cloud services and managed infrastructure directly into customer data centers while managed via the public cloud control plane.

Answer

OCI Local Region

Answer

OCI Public Cloud Region

Answer

OCI Dedicated Region

Question 2

An enterprise cloud architect is evaluating OCI's distributed cloud model and wants to understand how resource management, IAM policies, and API endpoints are handled across a customer's OCI Dedicated Region compared to standard public regions. Which statement accurately describes the control plane architecture?

Accepted Answer

Dedicated regions share the same public cloud control plane, APIs, and management tools, ensuring identical operational experiences.. OCI Dedicated Regions are managed remotely by the same control plane and APIs used in OCI public regions, ensuring uniform management while data remains local.

Answer

Dedicated regions cannot access native OCI services like Object Storage or Autonomous Database.

Answer

Dedicated regions do not support Identity and Access Management (IAM) because they are entirely disconnected from Oracle.

Answer

Dedicated regions require a completely isolated, on-premises local control plane managed independently by local administrators.

Question 3

Which TWO characteristics accurately describe Oracle Cloud Infrastructure (OCI) Fault Domains?

Accepted Answer

They provide anti-affinity by ensuring instances placed in different fault domains do not run on the same physical hardware.. Option B is correct because fault domains provide anti-affinity: instances placed in different fault domains within an availability domain are guaranteed not to share the same physical hardware, so a single hardware failure cannot affect both. Option D is correct because fault domains are designed to protect against hardware failures and power supply outages within a single availability domain, allowing you to distribute resources for high availability. Option A is incorrect because each availability domain contains three fault domains, not exactly one. Option C is incorrect because fault domains are scoped within a single availability domain, not across multiple geographic regions. Option E is incorrect because that describes availability domains, which are isolated data centers connected by high-speed, low-latency cross-links, not fault domains.

Answer

Each availability domain contains exactly one fault domain.

Answer

They span across multiple geographic regions to provide disaster recovery.

Answer

They are isolated data centers connected by high-speed, low-latency cross-links.

Question 4

Which THREE statements are true regarding the architecture and design principles of OCI Availability Domains (ADs) and Regions?

Accepted Answer

Some OCI regions are built with a single availability domain, while others contain multiple availability domains.. Option C is correct because OCI regions vary in topology: some regions are single-AD (for example, certain smaller or newer regions), while most commercial regions contain three availability domains, so the statement accurately reflects that AD count is not uniform across regions. Option D is correct because each OCI region is an independent, isolated geographic area, and regions are deliberately separated by large distances so that a regional failure does not affect other regions. Option E is correct because ADs within the same region are interconnected through a high-bandwidth, low-latency network, which enables multi-AD architectures such as cross-AD replication and low-latency synchronous data mirroring. Option A is incorrect because an availability domain is confined to a single region and cannot span multiple geographic countries. Option B is incorrect because each availability domain has independent power, cooling, and physical security infrastructure; sharing those would defeat the fault-isolation purpose of ADs.

Answer

An availability domain can span across multiple geographic countries to maximize data locality.

Answer

Availability domains share power, cooling, and physical security infrastructure to reduce operational overhead.

Question 5

Which TWO deployment models are part of Oracle Cloud Infrastructure's distributed cloud strategy, bringing cloud services closer to customers or specific data residency locations?

Accepted Answer

OCI Cloud@Customer. OCI's distributed cloud strategy includes Dedicated Regions and Cloud@Customer offerings, which bring public cloud services to customer-controlled locations.

Answer

OCI Virtual Private Tenant

Answer

OCI Local Compute Zone

Answer

OCI Bare Metal Isolated Instance

Question 6

A company is expanding its operations and requires the lowest possible latency for its application within a specific geographic area. Which OCI construct should they select to ensure their resources are located closest to their users?

Accepted Answer

Region. OCI Regions provide the primary geographic location for resources. Selecting the region closest to the user minimizes network latency.

Answer

Compartment

Answer

Availability Domain

Answer

Fault Domain

Question 7

You are deploying a critical application that must remain available even if a single hardware failure occurs within a specific data center. You have already chosen an Availability Domain. Which configuration provides the best protection against this failure?

Accepted Answer

Place instances in different Fault Domains. Fault domains allow for the distribution of instances across different hardware within an Availability Domain to protect against localized hardware or rack failure.

Answer

Use a single compute instance with high-performance storage

Answer

Place instances in different regions

Answer

Place instances in different compartments

Question 8

An administrator needs to organize OCI resources to manage billing and access control for different departments. Which OCI feature is designed for this purpose?

Accepted Answer

Compartment. Compartments are OCI's fundamental logical grouping mechanism for isolating and organizing resources. They are used to separate resources by department, environment, or project, and IAM policies and budgets can be scoped to individual compartments. This makes them the correct answer for managing both billing and access control across departments.

Answer

Tenancy

Answer

Fault Domain

Answer

Availability Domain

Question 9

Your application requires high availability, and you want to ensure that your instances are not all updated or patched at the exact same time. Which OCI concept ensures that maintenance events are distributed?

Accepted Answer

Fault Domain distribution. Distributing instances across different Fault Domains ensures that Oracle maintenance tasks (like patching) occur at different times for each domain, maintaining application uptime.

Answer

Availability Domain isolation

Answer

Regional placement

Answer

Compartment policy

Question 10

A financial institution is prohibited by regulation from storing data in any public data center, even if it is encrypted. They require a complete, physically isolated OCI deployment. What is the recommended deployment?

Accepted Answer

OCI Dedicated Region. The OCI Dedicated Region provides a fully integrated, physically isolated OCI footprint exclusively for a single customer.

Answer

OCI Cloud@Customer with public peering

Answer

OCI Public Cloud

Answer

OCI Hybrid Cloud with VPN

Question 11

Which THREE components or services are part of the OCI distributed cloud strategy, providing flexibility in where and how cloud services are consumed?

Accepted Answer

OCI Cloud@Customer. OCI's distributed cloud strategy is built around delivering the same OCI services across multiple deployment locations, and three of the listed options are core to that model. Option B, OCI Cloud@Customer, is correct because it places OCI infrastructure and services inside a customer's own data center while Oracle operates and manages it, extending the cloud to on-premises environments. Option C, OCI Public Cloud, is correct because it is the standard multi-tenant public cloud region offering that anchors the distributed cloud portfolio. Option E, OCI Dedicated Region, is correct because it delivers a full OCI region within a customer's premises or chosen location with the same services and SLAs as the public cloud, giving dedicated capacity and isolation. The remaining options do not belong: OCI Resource Manager (A) is an infrastructure-as-code orchestration service for provisioning OCI resources via Terraform, and OCI Data Catalog (D) is a metadata management and data discovery service—both are individual platform services, not distributed cloud deployment models.

Answer

OCI Resource Manager

Answer

OCI Data Catalog

Question 12

When architecting a solution for high availability in OCI, which TWO factors should be considered to ensure that your application remains resilient?

Accepted Answer

Distributing compute resources across multiple Fault Domains. Option B is correct because Fault Domains are isolated groups of hardware within an Availability Domain, so distributing compute resources across multiple Fault Domains prevents a single hardware failure from taking down the entire application, which is a core HA design principle in OCI. Option E is correct because using multiple Availability Domains (each with independent power, cooling, and network) or multiple Regions provides geographic redundancy, allowing the application to survive a full AD or regional outage. Option A is wrong because concentrating all instances in one Fault Domain creates a single point of failure and actually reduces resilience. Option C is wrong because compartments are logical IAM/organizational containers, not a high-availability mechanism, and grouping services in one compartment has no bearing on fault tolerance. Option D is wrong because a load balancer with no backends cannot route traffic to any application servers, so it provides no availability at all.

Answer

Placing all compute instances in a single Fault Domain for performance

Answer

Configuring all services to exist in the same compartment for simplified access

Answer

Using a single load balancer with no backends

Question 13

A company is deploying a web application on OCI and needs to distribute incoming traffic across multiple compute instances for high availability. Which OCI service should they use?

Accepted Answer

Load Balancer. The OCI Load Balancer is designed to distribute incoming traffic across multiple compute instances, providing high availability and fault tolerance. It supports health checks and can scale automatically. Other services like Internet Gateway, NAT Gateway, and DRG serve different networking purposes and cannot perform load balancing.

Answer

Internet Gateway

Answer

Dynamic Routing Gateway

Answer

NAT Gateway

Question 14

A financial services company needs to store sensitive data in OCI with strict access controls and auditing. Which OCI service should they use to manage encryption keys and secrets?

Accepted Answer

Key Management. OCI Key Management is designed to securely store and manage encryption keys and secrets, with features like key rotation and integration with other OCI services. It provides the necessary controls and auditing for sensitive data. IAM, Cloud Guard, and Audit serve different security functions and do not manage keys.

Answer

Identity and Access Management (IAM)

Answer

Audit

Answer

Cloud Guard

Question 15

A solutions architect is designing a VCN with public and private subnets. Instances in the private subnet need to download security patches from the internet but must not be directly accessible from the internet. Which configuration should the architect implement?

Accepted Answer

Attach a NAT Gateway to the VCN and configure a route in the private subnet's route table to the NAT Gateway.. A NAT Gateway enables instances in a private subnet to initiate outbound internet connections while blocking inbound traffic, which is exactly what is needed for patch downloads without direct accessibility. Internet Gateway would expose instances, while Service Gateway and Dynamic Routing Gateway serve other connectivity purposes.

Answer

Attach an Internet Gateway to the VCN and configure a route in the private subnet's route table to the Internet Gateway.

Answer

Attach a Dynamic Routing Gateway to the VCN and configure a route in the private subnet's route table to the Dynamic Routing Gateway.

Answer

Attach a Service Gateway to the VCN and configure a route in the private subnet's route table to the Service Gateway.
