NEW QUESTION 56
Which gateway can be used to provide internet access to an Oracle Cloud Infrastructure compute instance in a private subnet?
- A. NAT Gateway
- B. Dynamic Routing Gateway
- C. Service Gateway
- D. Internet Gateway
Answer: A
Explanation:
Explanation
A NAT gateway gives cloud resources without public IP addresses access to the internet without exposing those resources to incoming internet connections.
NAT is a networking technique commonly used to give an entire private network access to the internet without assigning each host a public IPv4 address. The hosts can initiate connections to the internet and receive responses, but not receive inbound connections initiated from the internet.
NEW QUESTION 57
Which three components are part of Oracle Cloud Infrastructure Identity and Access Management service?
- A. Policies
- B. Virtual Cloud Networks
- C. Roles
- D. Users
- E. Dynamic Groups
- F. Compute Instances
- G. Regional Subnets
Answer: A,D,E
Explanation:
Explanation
IAM components are
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).
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.
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.
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.

NEW QUESTION 60
Which resource do you manage in an Infrastructure-as-a-services (IAAS) offering?
- A. Storage
- B. Servers
- C. Network
- D. Operating system
Answer: D
Explanation:
Explanation
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.
NEW QUESTION 61
Which statement accurately describes an Oracle Cloud Infrastructure Region?
- A. Each Availability Domain has a single Fault Domain.
- B. Each Fault Domain has multiple Availability Domains.
- C. Each Availability Domain has three Fault Domains.

Answer: C
Explanation:
Explanation
Oracle Cloud Infrastructure is based on regions and availability domains.
A region is a localized geographic area, and an availability domain is one or more data centres located within a region.
A region is composed of one or more availability domains.
Each availability domain contains three fault domains.

NEW QUESTION 65
Which service is the most effective for moving large amounts of data from your on-premises to Oracle Cloud Infrastructure (OCI)?
- A. Dynamic Routing Gateway
- B. Internet Gateway
- C. Data Transfer appliance
- D. Data Safe
Answer: C
Explanation:
Explanation
APPLIANCE-BASED DATA TRANSFER
You send your data as files on secure, high-capacity, Oracle-supplied storage appliances to an Oracle transfer site. Operators at the Oracle transfer site upload the data into your designated Object Storage bucket in your tenancy.
This solution supports data transfer when you are migrating a large volume of data and when using disks is not a practical alternative. You do not need to write any code or purchase any hardware. Oracle supplies the transfer appliance and software required to manage the transfer.
