Question 2

When architecting a high-availability database cluster across multiple availability domains in an OCI region, what is the recommended approach for handling latency-sensitive synchronous replication?

Accepted Answer

Leverage the low-latency high-bandwidth inter-AD network for synchronous replication.. Since availability domains within an OCI region are connected by low-latency networks, synchronous replication is fully supported across them.

Answer

Use asynchronous replication because inter-availability domain latency is too high for synchronous replication.

Answer

Deploy all database nodes in the same fault domain to achieve synchronous replication.

Answer

Route replication traffic through the public internet to bypass regional limits.

Question 3

An enterprise is planning a multi-cloud strategy and needs to connect their OCI tenancy directly to Microsoft Azure with extremely low latency and high throughput. Which OCI architectural feature or partnership makes this possible?

Accepted Answer

Oracle Interconnect for Azure. Oracle Interconnect for Azure provides direct, low-latency, high-throughput connectivity between OCI and Microsoft Azure in select regions.

Answer

OCI Dynamic Routing Gateway (DRG) peering over the internet

Answer

OCI Cloud Guard cross-cloud integration

Answer

OCI FastConnect with public peering

Question 4

In an OCI region with a single availability domain, how does OCI achieve high availability and fault isolation for compute workloads?

Accepted Answer

By utilizing multiple fault domains within that single availability domain.. In regions with a single availability domain, OCI relies on multiple fault domains to distribute workloads across isolated physical hardware.

Answer

By provisioning multiple availability domains dynamically behind the scenes.

Answer

By requiring users to manually peer across international regions.

Answer

High availability is not possible in single-AD regions.

Question 5

When evaluating OCI regions for deploying a new application, you notice that some regions are designated as having multiple availability domains while others have only one. What is a key design implication when deploying to a single-AD region?

Accepted Answer

You must rely on fault domains for hardware isolation and another region for disaster recovery.. Single-AD regions lack multiple physical data center facilities, so high availability must rely on fault domains for hardware isolation.

Answer

Compute instances are automatically spread across other global regions.

Answer

Storage services are automatically replicated across public clouds.

Answer

You cannot deploy fault domains in a single-AD region.

Question 6

Which TWO OCI concepts are fundamental for organizing resources and managing access control within a tenancy? (Choose two.)

Accepted Answer

Compartments. Compartments are used to organize and isolate resources, and IAM policies control who can access those resources within compartments.

Answer

Availability Domains

Answer

Fault Domains

Answer

Internet Gateways

Question 7

Which TWO of the following statements accurately describe OCI Availability Domains? (Choose two.)

Accepted Answer

Availability domains are connected to each other by a high-bandwidth, low-latency network.. Option A is correct because OCI Availability Domains within a region are interconnected by a dedicated high-bandwidth, low-latency network, which enables low-latency communication between resources in different ADs while still supporting high availability designs. Option C is correct because each Availability Domain is physically isolated from the others, with independent power, cooling, and network infrastructure, so a failure in one AD does not affect the others. Option B is incorrect because Availability Domains are physical data center groupings, not purely logical constructs. Option D is incorrect because a fault domain is a grouping within a single Availability Domain and cannot span multiple ADs. Option E is incorrect because Availability Domains are region-specific and are not shared across distinct OCI regions.

Answer

Availability domains are purely logical constructs with no physical representation.

Answer

A single fault domain can span across multiple availability domains.

Answer

Availability domains are shared across multiple distinct OCI regions.

Question 8

Which THREE components are typically isolated from each other across different Fault Domains within an Availability Domain? (Choose three.)

Accepted Answer

Top-of-rack network switches. Fault domains isolate instances from shared physical hardware racks, power sources, and top-of-rack switches.

Answer

Geographic regions

Answer

Building facilities

Question 9

Which TWO options correctly describe features of OCI Regions? (Choose two.)

Accepted Answer

Regions are completely independent and do not share infrastructure with other regions.. Option B is correct because OCI regions are designed as isolated geographic areas with independent infrastructure, so they do not share physical infrastructure such as data centers, power, or networking with other regions. Option D is correct because an OCI region contains one or more availability domains, and the number can vary by region rather than being fixed. Option A is incorrect because not every OCI region has exactly three availability domains; some regions have one availability domain, while others may have three. Option C is incorrect because a region is a localized geographic area and does not span multiple continents simultaneously. Option E is incorrect because regions are physical/logical deployment boundaries for resources and services, not constructs used exclusively for billing.

Answer

Every OCI region is guaranteed to have exactly three availability domains.

Answer

Regions span across multiple continents simultaneously.

Answer

Regions are logical constructs used exclusively for billing purposes.

Question 10

Which THREE OCI deployment models are part of the OCI distributed cloud strategy? (Choose three.)

Accepted Answer

OCI Dedicated Region. OCI's distributed cloud model includes Public Cloud, Dedicated Region, and Cloud@Customer offerings.

Answer

OCI Regional Edge Node

Answer

OCI Standalone Local Zone

Question 11

When designing a disaster recovery and high availability architecture across OCI, which TWO strategies help achieve high availability and fault tolerance? (Choose two.)

Accepted Answer

Distributing critical application instances across multiple fault domains within an availability domain.. Option D is correct because distributing critical application instances across multiple fault domains within an availability domain provides fault tolerance against hardware failures, since each fault domain has independent power and network infrastructure, so a failure in one fault domain does not affect instances in others. Option E is correct because replicating data and workloads across multiple OCI regions provides disaster recovery and geographic redundancy, protecting against region-wide outages and enabling business continuity through services like OCI Full Stack Disaster Recovery, remote replication, and cross-region backups. Option A is incorrect because a single availability domain with no redundancy creates a single point of failure, offering neither high availability nor fault tolerance. Option B is incorrect because placing all instances in a single fault domain concentrates risk, so a fault domain failure would take down the entire workload despite any local communication benefit. Option C is incorrect because creating resources in the root tenancy without compartments is an organizational and access-control anti-pattern that has no bearing on high availability or fault tolerance.

Answer

Relying solely on a single availability domain with no redundancy.

Answer

Placing all database and application instances in a single fault domain for faster local communication.

Answer

Creating all resources in the root tenancy without compartments.

Question 12

An administrator needs to deploy a critical production database across multiple data centers in the same OCI region to protect against unexpected hardware failure while ensuring lowest possible network latency for synchronous replication. Which component should the administrator leverage?

Accepted Answer

Availability Domains. Availability Domains (ADs) are isolated, independent data centers within a region, connected with high-performance, low-latency networks, making them ideal for high availability within the same region.

Question 13

A multinational corporation has strict data residency regulations that prohibit their core financial data from leaving their physical corporate headquarters, yet they want to use OCI managed services and the exact same control plane API. Which OCI deployment model satisfies these requirements?

Accepted Answer

OCI Dedicated Region. OCI Dedicated Region or OCI Cloud@Customer allows organizations to run OCI services on-premises, maintaining data residency while using the public cloud control plane and APIs.

Answer

OCI Multi-Cloud Interconnect

Answer

OCI Public Cloud Region

Answer

OCI Global Edge Services

Question 14

A DevOps engineer is provisioning compute instances in a region that has a single availability domain. To protect the application from unexpected physical hardware failures and power supply outages within that single availability domain, how should the engineer distribute the instances?

Accepted Answer

Across different Fault Domains. Fault domains provide anti-affinity and isolate instances across different physical hardware, power, and network infrastructure within a single availability domain.

Answer

Across multiple OCI Regions

Answer

Inside the same Fault Domain

Answer

Across multiple Availability Domains

Question 15

An organization requires a complete disaster recovery site located in a different geographic jurisdiction hundreds of miles away to comply with business continuity mandates, ensuring data replication across independent regions. Which construct forms the foundational basis for this requirement?

Accepted Answer

OCI Regions. OCI Regions are independent, geographically separated data-center groups, and replication across regions is the construct that satisfies a disaster-recovery site in a different jurisdiction. Regions are isolated from one another by design, so placing a DR site in a separate region provides the geographic and administrative separation the mandate requires. This makes OCI Regions the foundational basis for cross-jurisdiction DR.
