Correct Answer: C

COMPARTMENT A collection of related resources. Compartments are a fundamental component of

Oracle Cloud Infrastructure for organizing and isolating your cloud resources. You use them to clearly

separate resources for the purposes of measuring usage and billing, access (through the use of policies),

and isolation (separating the resources for one project or business unit from another).

A common approach is to create a compartment for each major part of your organization.

User Group can use some resources in the compartment like network resources also they can't create it

depend on the policy that assigned Remember, a compartment is a logical grouping, not a physical one

Correct Answer: AE

A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain. A hardware failure or Compute hardware maintenance event that affects one fault domain does not affect instances in other fault domains. In addition, the physical hardware in a fault domain has independent and redundant power supplies, which prevents a failure in the power supply hardware within one fault domain from affecting other fault domains. To control the placement of your compute instances, bare metal DB system instances, or virtual machine DB system instances, you can optionally specify the fault domain for a new instance or instance pool at launch time. If you don't specify the fault domain, the system selects one for you. Oracle Cloud Infrastructure makes a best-effort anti-affinity placement across different fault domains, while optimizing for available capacity in the availability domain. To change the fault domain for an instance, terminate it and launch a new instance in the preferred fault domain. Use fault domains to do the following things: Protect against unexpected hardware failures or power supply failures. Protect against planned outages because of Compute hardware maintenance. We can use fault domains to do the following things: 1) Protect against unexpected hardware failures or power supply failures. 2) Protect against planned outages because of Compute hardware maintenance Reference: https://docs.cloud.oracle.com/en-us/iaas/Content/General/Concepts/regions.htm

Correct Answer: D

Oracle Cloud Infrastructure is a set of complementary cloud services that enable you to build and run a wide range of applications and services in a highly available hosted environment. Oracle Cloud Infrastructure offers high-performance compute capabilities (as physical hardware instances) and storage capacity in a flexible overlay virtual network that is securely accessible from your on- premises network. Reference: https://docs.cloud.oracle.com/en-us/iaas/Content/GSG/Concepts/baremetalintro.htm One of the major benefits of cloud computing is REDUCED TCO. Therefore, Increased TCO is the incorrect option. https://www.oracle.com/partners/en/partner-with-oracle/develop-solutions/why/increase-value- reducecost-3907933.pdf

Correct Answer: C

Oracle Cloud Infrastructure File Storage service provides a durable, scalable, secure, enterprise-grade network file system. You can connect to a File Storage service file system from any bare metal, virtual machine, or container instance in your Virtual Cloud Network (VCN). You can control the access of the file system from FSS by applying some security rules and others but the services it self not related to security but it related to shared storage Reference: https://docs.cloud.oracle.com/en-us/iaas/Content/File/Concepts/filestorageoverview.htm

Correct Answer: C

Components of IAM RESOURCE The cloud objects that your company's employees create and use when interacting with Oracle Cloud Infrastructure. For example: compute instances, block storage volumes, virtual cloud networks (VCNs), subnets, route tables, etc. USER An individual employee or system that needs to manage or use your company's Oracle Cloud Infrastructure resources. Users might need to launch instances, manage remote disks, work with your virtual cloud network, etc. End users of your application are not typically IAM users. Users have one or more IAM credentials (see User Credentials). GROUP A collection of users who all need the same type of access to a particular set of resources or compartment. DYNAMIC GROUP A special type of group that contains resources (such as compute instances) that match rules that you define (thus the membership can change dynamically as matching resources are created or deleted). These instances act as "principal" actors and can make API calls to services according to policies that you write for the dynamic group. NETWORK SOURCE A group of IP addresses that are allowed to access resources in your tenancy. The IP addresses can be public IP addresses or IP addresses from a VCN within your tenancy. After you create the network source, you use policy to restrict access to only requests that originate from the IPs in the network source. COMPARTMENT A collection of related resources. Compartments are a fundamental component of Oracle Cloud Infrastructure for organizing and isolating your cloud resources. You use them to clearly separate resources for the purposes of measuring usage and billing, access (through the use of policies), and isolation (separating the resources for one project or business unit from another). A common approach is to create a compartment for each major part of your organization. For more information, see Setting Up Your Tenancy. TENANCY The root compartment that contains all of your organization's Oracle Cloud Infrastructure resources. Oracle automatically creates your company's tenancy for you. Directly within the tenancy are your IAM entities (users, groups, compartments, and some policies; you can also put policies into compartments inside the tenancy). You place the other types of cloud resources (e.g., instances, virtual networks, block storage volumes, etc.) inside the compartments that you create. POLICY A document that specifies who can access which resources, and how. Access is granted at the group and compartment level, which means you can write a policy that gives a group a specific type of access within a specific compartment, or to the tenancy itself. If you give a group access to the tenancy, the group automatically gets the same type of access to all the compartments inside the tenancy. For more information, see Example Scenario and How Policies Work. The word "policy" is used by people in different ways: to mean an individual statement written in the policy language; to mean a collection of statements in a single, named "policy" document (which has an Oracle Cloud ID (OCID) assigned to it); and to mean the overall body of policies your organization uses to control access to resources. HOME REGION The region where your IAM resources reside. All IAM resources are global and available across all regions, but the master set of definitions reside in a single region, the home region. You must make changes to your IAM resources in your home region. The changes will be automatically propagated to all regions. For more information, see Managing Regions. FEDERATION A relationship that an administrator configures between an identity provider and a service provider. When you federate Oracle Cloud Infrastructure with an identity provider, you manage users and groups in the identity provider. You manage authorization in Oracle Cloud Infrastructure's IAM service. Oracle Cloud Infrastructure tenancies are federated with Oracle Identity Cloud Service by default. Reference:

Correct Answer: A

Infrastructure as a service (IaaS) is a type of cloud service model in which computing resources are hosted

in the cloud. Businesses can use the IaaS model to shift some or all of their use of on- premises or

colocated data center infrastructure to the cloud, where it is owned and managed by a cloud provider.

These infrastructure elements can include compute, network, and storage hardware as well as other

components and software.

How Does IaaS Work?

In a typical IaaS model, a business--which can be of any size--consumes services like compute, storage,

and databases from a cloud provider. The cloud provider offers those services by hosting hardware and

software in the cloud. The business will no longer need to purchase and manage its own equipment, or

space to host the equipment, and the cost will shift to a pay-as-you-go model.

When the business needs less, it pays for less. And when it grows, it can provision additional computing

resources and other technologies in minutes.

Correct Answer: B

A shape is a template that determines the number of CPUs, amount of memory, and other resources that

are allocated to an instance.

The network bandwidth is directly proportional to the number of OCPUs in the instance shape!
