NEW QUESTION 1
Which statement below is not true for Oracle Cloud infrastructure Compartments?

• A. Resources can be moved from one compartment to another
• B. Compartments cannot be nested
• C. Each OCI resource belongs to a single compartment
• D. Resources and compartments can be added and deleted anytime

Answer: B

Explanation:
When creating a compartment, you must provide a name for it (maximum 100 characters, including letters, numbers, periods, hyphens, and underscores) that is unique within its parent compartment. You must also provide a description, which is a non-unique, changeable description for the compartment, from 1 through 400 characters. Oracle will also assign the compartment a unique ID called an Oracle Cloud ID.
You can create subcompartments in compartments to create hierarchies that are six levels deep.

NEW QUESTION 2
Which three components are part of Oracle Cloud Infrastructure (OCI) identity and access management service?

• A. Regional Subnets
• B. Policies
• C. Users
• D. Compute Instances
• E. Dynamic Groups
• F. Roles
• G. Virtual Cloud Networks

Answer: BCE

Explanation:
Components of IAMIAM uses the components described in this section. To better understand how the components fit together, see Example Scenario.
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. Ora 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 regio 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 3
Which statement accurately describes an Oracle Cloud Infrastructure Region?

• A. Each Availability Domain has a single Fault Domain.
• B. Each Availability Domain has three Fault Domains.
• C. Each Fault Domain has multiple Availability Domains.
• D. Each region has a single Fault Domain.

Answer: B

Explanation:
Oracle Cloud Infrastructure is hosted in regions and availability domains. A region is a localized geographic area, and an availability domain is one or more data centers located within a region. A region is composed of one or more availability domains. Most Oracle Cloud Infrastructure resources are either region-specific, such as a virtual cloud network, or availability domain-specific, such as a compute instance. Traffic between availability domains and between regions is encrypted.
Availability domains are isolated from each other, fault tolerant, and very unlikely to fail simultaneously. Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region.
The availability domains within the same region are connected to each other by a low latency, high bandwidth network, which makes it possible for you to provide high-availability connectivity to the internet and on-premises, and to build replicated systems in multiple availability domains for both high-availability and disaster recovery.
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.

NEW QUESTION 8
Which capability can be used to protect against unexpected hardware or power supply failures within an availability domain?

• A. Fault Domains
• B. Compartments
• C. Top of Rack Switches
• D. Power Distribution Units

Answer: A

Explanation:
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 instanc 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.
Usually 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.

NEW QUESTION 9
What two statements regarding the Virtual Cloud Network (VCN) are true?

• A. A single VCN can contain both private and public Subnets.
• B. VCN is a regional resource that span across all the Availability Domains in a Region.
• C. You can only create one VCN per region.
• D. The VCN is the IPSec-based connection with a remote on premises location.
• E. VCN is a global resource that span across all the Regions

Answer: AB

Explanation:
When you work with Oracle Cloud Infrastructure, one of the first steps is to set up a virtual cloud network (VCN) for your cloud resources.
VIRTUAL CLOUD NETWORK (VCN) :
A virtual, private network that you set up in Oracle data centers. It closely resembles a traditional network, with firewall rules and specific types of communication gateways that you can choose to use. A VCN resides in a single Oracle Cloud Infrastructure region and covers a single, contiguous IPv4 CIDR block of your choice. See Allowed VCN Size and Address Ranges. The terms virtual cloud network, VCN, and cloud network are used interchangeably in this documentation. For more information, see VCNs and Subnets.
SUBNETS :
Subdivisions you define in a VCN (for example, 10.0.0.0/24 and 10.0.1.0/24). Subnets contain virtual network interface cards (VNICs), which attach to instances. Each subnet consists of a contiguous range of IP addresses that do not overlap with other subnets in the VCN. You can designate a subnet to exist either in a single availability domainavailability domain
or across an entire region (regional subnets are recommended). Subnets act as a unit of configuration within the VCN: All VNICs in a given subnet use the same route table, security lists, and DHCP options (see the definitions that follow). You can designate a subnet as either public or private when you create it. Private means VNICs in the subnet can't have public IP addresses. Public means VNICs in the subnet can have public IP addresses at your discretion. See Access to the Internet.

Use the tool for spot checks of spending trends and for generating reports

NEW QUESTION 12
Which Oracle cloud infrastructure capability can be used to protect against power failures within an availability Domain?

• A. Data Plane
• B. Fault Domains
• C. Services Cells
• D. Top of Rack Switch

Answer: B

Explanation:
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.

NEW QUESTION 13
Oracle Cloud Infrastructure Budgets can be set on which two options?

• A. Free-form tags
• B. Compartments
• C. Tenancy
• D. Virtual Cloud Network
• E. Cost-tracking tags

Answer: BE

Explanation:
A budget can be used to set soft limits on your Oracle Cloud Infrastructure spending. You can set alerts on your budget to let you know when you might exceed your budget, and you can view all of your budgets and spending from one single place in the Oracle Cloud Infrastructure console.
How Budgets Work:
Budgets are set on cost-tracking tags or on compartments (including the root compartment) to track all spending in that cost-tracking tag or for that compartment and its children.
All budgets alerts are evaluated every 15 minutes. To see the last time a budget was evaluated, open the details for a budget. You will see fields that show the current spend, the forecast and the "Spent in period" field which shows you the time period over which the budget was evaluated. When a budget alert fires, the email recipients configured in the budget alert receive an email.

NEW QUESTION 14
Which pricing model is NOT supported by Oracle Cloud Infrastructure?

• A. Reserved Infrastructure
• B. Universal Credits - Monthly Flex
• C. Bring your own license
• D. Pay-as-you-go

Answer: A

Explanation:
The available purchase models are:
Pay As You Go (PAYG):Billed in arrears based on consumption. Recommended for organizations who are trying new services, rapid prototyping, or for elastic scaling.
Monthly Flex:Billed in advance with a 12-month minimum. Use monthly or forfeit that month’s credits.Recommended for customers with predictable production workloads or large long-running applications, such as HR, payroll, analytics, and more.Monthly Flex maximizes cost reduction with predictable
monthly spend, similar to your monthly phone plan. Delivers faster time to market by offering customers the choice of using any IaaS and PaaS services.
Oracle’s current PaaS offering is “license-included PaaS.” It includes:
· Compute and compute support
· Automation
· License entitlement and license support Bring your own license
BYOL stands for “bring your own license.” Previously, you could bring your own licenses to Oracle IaaS, but to get the benefits of PaaS automation, you couldn’t leverage existing licenses. This has been changed. We’re offering Oracle BYOL to PaaS, enabling our customers to leverage their investment in existing on-premises licenses in their journey to the cloud.
Oracle BYOL to PaaS includes:
· Compute and compute support
· Automation
· Customers bring their on-premises license entitlement and get license support via their existing on-premises support contract.
· As customers leverage their existing on-premises license entitlement, they can move to the cloud at a lower cost.

NEW QUESTION 15
A banking platform has been re-designed to a microservices based architecture using Docker containers for deployment.
Which service can you use to deploy containers on Oracle Cloud Infrastructure (OCI)?

• A. Container Engine for Kubernetes (OKE)
• B. Streaming Service
• C. API Gateway
• D. File Storage Service

Answer: A

Explanation:
Oracle Cloud Infrastructure Container Engine for Kubernetes is a fully-managed, scalable, and highly available service that you can use to deploy your containerized applications to the cloud. Use Container Engine for Kubernetes (sometimes abbreviated to just OKE) when your development team wants to reliably build, deploy, and manage cloud-native applications. You specify the compute resources that your applications require, and Container Engine for Kubernetes provisions them on Oracle Cloud Infrastructure in an existing OCI tenancy.
Container Engine for Kubernetes uses Kubernetes - the open-source system for automating deployment, scaling, and management of containerized applications across clusters of hosts. Kubernetes groups the containers that make up an application into logical units (called pods) for easy management and discovery.
You can access Container Engine for Kubernetes to define and create Kubernetes clusters using the Console and the REST API. You can access the clusters you create using the Kubernetes command line (kubectl), the Kubernetes Dashboard, and the Kubernetes API.
Container Engine for Kubernetes is integrated with Oracle Cloud Infrastructure Identity and Access Management (IAM), which provides easy authentication with native Oracle Cloud Infrastructure identity
functionality.

NEW QUESTION 16
Which kind of scaling is supported by virtual machines in Oracle Cloud Infrastructure Compute service?

• A. Only scaling up or down
• B. Only scaling out
• C. Scaling up or down, and scaling in or out
• D. Only scaling in

Answer: C

Explanation:
Horizontal scaling means that you scale by adding more machines into your pool of resources
whereas Vertical scaling means that you scale by adding more power (CPU, RAM) to an existing machine.
An easy way to remember this is to think of a machine on a server rack, we add more machines across the horizontal direction and add more resources to a machine in the vertical direction.

With horizontal-scaling it is often easier to scale dynamically by adding more machines into the existing pool
— Vertical-scaling is often limited to the capacity of a single machine, scaling beyond that capacity often involves downtime and comes with an upper limit.

NEW QUESTION 17
A customer wants to use Oracle Cloud Infrastructure (OCI) for storing application backups which can be stored based on business needs.
Which OCI storage service can be used to meet the requirement?

• A. File Storage
• B. Block Volume
• C. Archive Storage
• D. Object Storage (standard)

Answer: D

Explanation:
Oracle Cloud Infrastructure offers two distinct storage class tiers to address the need for both performant, frequently accessed "hot" storage, and less frequently accessed "cold" storage. Storage tiers help you maximize performance where appropriate and minimize costs where possible.
1) Use Object Storage for data to which you need fast, immediate, and frequent access. Data accessibility an performance justifies a higher price to store data in the Object Storage tier.
2) Use Archive Storage for data to which you seldom or rarely access, but that must be retained and preserve for long periods of time. The cost efficiency of the Archive Storage tier offsets the long lead time required to access the data. For more information, see Overview of Archive Storage.
The Oracle Cloud Infrastructure Object Storage service is an internet-scale, high-performance storage platform that offers reliable and cost-efficient data durability. The Object Storage service can store an unlimited amount
of unstructured data of any content type, including analytic data and rich content, like images and videos.
With Object Storage, you can safely and securely store or retrieve data directly from the internet or from within the cloud platform. Object Storage offers multiple management interfaces that let you easily manage storage at scale. The elasticity of the platform lets you start small and scale seamlessly, without experiencing any degradation in performance or service reliability.
Object Storage is a regional service and is not tied to any specific compute instance. You can access data from anywhere inside or outside the context of the Oracle Cloud Infrastructure, as long you have internet connectivity and can access one of the Object Storage endpoints. Authorization and resource limits are discussed later in this topic.
Object Storage also supports private access from Oracle Cloud Infrastructure resources in a VCN through
a service gateway. A service gateway allows connectivity to the Object Storage public endpoints from private IP addresses in private subnets. For example, you can back up DB systems to an Object Storage bucket over the Oracle Cloud Infrastructure backbone instead of over the internet. You can optionally use IAM policies to control which VCNs or ranges of IP addresses can access Object Storage. See Access to Oracle Services: Service Gateway for details.
Object Storage is Always Free eligible. For more information about Always Free resources, including additional capabilities and limitations, see Oracle Cloud Infrastructure Free Tier.
The following list summarizes some of the ways that you can use Object Storage.

• A. Public internet
• B. Virtual Cloud Network Remote Peering
• C. OCI FastConnact
• D. IPSec Virtual Private Network (VPN)

Answer: C

Explanation:
Oracle Cloud Infrastructure FastConnect provides an easy way to create a dedicated, private connection between your data center and Oracle Cloud Infrastructure. FastConnect provides higher-bandwidth options, and a more reliable and consistent networking experience compared to internet-based connections.

NEW QUESTION 19
A new customer has logged into Oracle Cloud Infrastructure (OCI) as an administrator for the first time. The admin would like to deploy Infrastructure into a region other then their home region.
What is the first Stop they must take in order to accomplish this task?

• A. Use API endpoints to create resources in the desired region.
• B. Navigate to the desired region and begin creating resources.
• C. Subscribe to the desired region.
• D. File a service request for access to each additional region.

Answer: C

Explanation:
When you sign up for Oracle Cloud Infrastructure, Oracle creates a tenancy for you in one region. This is your home region. Your home region is where your IAM resources are defined. When you subscribe to another region, your IAM resources are available in the new region, however, the master definitions reside in your home region and can only be changed there.
When you subscribe your tenancy to a new region, all the policies from your home region are enforced in the new region. If you want to limit access for groups of users to specific regions, you can write policies to grant access to specific regions only.

NEW QUESTION 20
Which capability enables you to search, purchase, and start using software in your Oracle Cloud Infrastructure (OCI) tenancy?

• A. OCI Marketplace
• B. OCI OS Management
• C. OCI Resource Manager
• D. OCI Registry

Answer: A

Explanation:
Oracle Cloud Infrastructure Marketplace is an online store that offers solutions specifically for customers of Oracle Cloud Infrastructure. In the Oracle Cloud Infrastructure Marketplace catalog, you can find listings for two types of solutions from Oracle and trusted partners: images and stacks. These listing types include different categories of applications. Also, some listings are free and others require payment.
Images are templates of virtual hard drives that determine the operating system and software to run on an instance. You can deploy image listings on an Oracle Cloud Infrastructure Compute instance. Marketplace also offers stack listings. Stacks represent definitions of groups of Oracle Cloud Infrastructure resources that you can act on as a group. Each stack has a configuration consisting of one or more declarative configuration files. With an image or a stack, you have a customized, more streamlined way of getting started with a publisher's software.
