1. Q1

   Which statement best describes OCI's distributed cloud approach?

   1. OCI services are available only in Oracle-owned public regions
   2. OCI delivers consistent cloud services across public regions, customer locations, and specialized sovereign environments
   3. OCI requires all workloads to run in a single global control plane
   4. OCI supports only SaaS applications, not infrastructure services

   Distributed cloud is the organizing idea behind OCI's 2026 blueprint: the same service catalog and the same console experience are delivered in Oracle-operated public regions, in customer data centers (Dedicated Region and Compute Cloud@Customer), and in sovereign or restricted environments. Option A describes a single-deployment public cloud, which is exactly what distributed cloud is meant to move beyond. Option C inverts the design — each region is independently operated rather than funneled through one control plane. Option D is wrong at the service-model level: OCI's distributed cloud is built on IaaS and PaaS primitives first, with SaaS applications running on top of them.
2. Q2

   In OCI, what is a region?

   1. A logical boundary inside a subnet
   2. A localized geographic area that contains one or more availability domains
   3. A single physical server rack
   4. A billing container for related services

   A region is a localized geographic area — Phoenix, Frankfurt, Singapore — that hosts one or more availability domains. Option A confuses a region with a subnet or security boundary. Option C describes hardware inside a fault domain, which is three levels below a region. Option D describes a compartment, which is a logical grouping for resources and policies, not a physical location.
3. Q3

   What is an availability domain in Oracle Cloud Infrastructure?

   1. A localized geographical area
   2. One or more data centers located within a region, isolated from other availability domains
   3. A type of encrypted traffic between regions
   4. A set of virtual cloud networks that share a route table

   An availability domain is a fault-isolated group of one or more data centers inside a region, with independent power, cooling, and network. Option A describes a region, one level up. Option C is nonsense — encryption is a property of traffic, not of a placement construct. Option D confuses an AD with a VCN, which is a software-defined network that can span availability domains.
4. Q4

   A team runs two web server instances in one availability domain and wants to protect them from a single hardware failure or planned hardware maintenance. What should they do?

   1. Place both instances in the same fault domain
   2. Move the instances to a different tenancy
   3. Put the instances in separate compartments
   4. Use different fault domains

   Fault domains are logical groupings of hardware inside a single availability domain, so spreading instances across them prevents one rack-level failure or maintenance event from taking out both. Option A does the opposite of the requirement. Option B changes ownership of the resources, not their physical placement. Option C is an organizational and access-control boundary with no effect on hardware isolation.
5. Q5

   Which OCI construct represents your organization's secure top-level cloud account?

   1. Compartment
   2. Availability domain
   3. Tenancy
   4. Fault domain

   The tenancy is the root container that holds all resources, identities, and policies for an organization; it is created when the account is signed up. Compartments (Option A) live inside the tenancy and subdivide it. Availability and fault domains (Options B and D) are physical placement constructs that exist in every tenancy regardless of how you organize resources.
6. Q6

   What is the main reason to use compartments in OCI?

   1. To increase internet bandwidth for a VCN
   2. To organize resources and apply access controls to separate teams or projects
   3. To replace identity groups for user management
   4. To convert a private subnet into a public subnet

   Compartments give you a logical grouping — by team, environment, or application — and IAM policies are scoped to them, which is what makes delegated administration and least privilege practical. Option A is a networking capacity matter handled by shape, bandwidth, and load balancing. Option C is wrong on two counts: groups hold users, compartments hold resources, and both are needed. Option D is purely a routing and public-IP decision inside a VCN.
7. Q7

   Which TWO statements about OCI compartments are true? (Choose two.)

   1. They must be in the resources' availability domain
   2. A resource can belong to several compartments at once
   3. Most resources can be moved to another compartment
   4. They're available in every subscribed region

   Compartments are logical, tenancy-wide constructs, so the same compartment name and hierarchy appear in every region you subscribe to (Option D), and most resources can be moved between compartments after creation, which is how you promote a workload from Dev to Prod without rebuilding it (Option C). Option A is false because compartments have no physical location. Option B is false — a resource belongs to exactly one compartment at a time, and that single-parent rule is what keeps policy evaluation unambiguous.
8. Q8

   When a tenancy is created, which compartment contains all other compartments and resources?

   1. The root compartment
   2. The default fault domain
   3. A compartment named Default
   4. The home availability domain

   Every tenancy starts with a root compartment that holds all other compartments and any resources created directly in it; policies written at the root apply tenancy-wide. Option B is a hardware grouping, not a compartment. Option C is not a reserved name — you can create a compartment called Default, but it has no special status and is not the root. Option D is a physical location construct.
9. Q9

   Which statement below is NOT true for Oracle Cloud Infrastructure compartments?

   1. Resources and compartments can be added and deleted anytime
   2. Compartments cannot be nested
   3. Resources can be moved from one compartment to another
   4. Each OCI resource belongs to a single compartment

   Compartments nest up to six levels deep, which is how enterprises mirror organizational hierarchies such as Business Unit > Environment > Application; that makes the claim in Option B the false statement. Option A is true — compartments are lightweight logical containers with no capacity of their own. Option C is true for most resource types. Option D is true, and the single-parent rule is what makes IAM policy inheritance predictable.
