NEW QUESTION # 53
Which TWO correctly describe the attributes of Oracle Cloud Infrastructure (OCI) compartments?
(Choose all correct answers)
- A. Compartments can be used to logically separate OCI resources.
- B. By default, your tenancy comes with a root compartment.
- C. Compartments cannot have sub compartments.
- D. Compartments can be used to physically separate OCI resources.
- E. Resources within one compartment cannot interact with resources in other compartments.
Answer: A,B
Explanation:
A compartment is a logical container that can hold OCI resources such as compute instances, block volumes, virtual cloud networks, etc. Compartments help you organize and control access to your resources based on business needs or security requirements3 By default, your tenancy comes with a root compartment that is the parent of all other compartments in your tenancy. You cannot delete the root compartment, but you can create subcompartments within it to further organize your resources3 Compartments can be used to logically separate OCI resources, not physically separate them. Resources within one compartment can interact with resources in other compartments, as long as the appropriate policies and network configurations are in place. For example, you can attach a compute instance in one compartment to a virtual cloud network in another compartment, or grant access to a user group in one compartment to manage resources in another compartment34
NEW QUESTION # 54
Which feature allows you to logically group and isolate your Oracle Cloud Infrastructure resources?
- A. Tenancy
- B. Compartments
- C. Identity and Access Management Groups
- D. Availability Domain
Answer: B
Explanation:
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

NEW QUESTION # 61
Which statement below is not true for Oracle Cloud infrastructure Compartments?
- A. Compartments cannot be nested
- B. Resources and compartments can be added and deleted anytime
- C. Each OCI resource belongs to a single compartment
- D. Resources can be moved from one compartment to another
Answer: A
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.
Reference:
https://docs.cloud.oracle.com/en-us/iaas/Content/Identity/Tasks/managingcompartments.htm When you first start working with Oracle Cloud Infrastructure, you need to think carefully about how you want to use compartments to organize and isolate your cloud resources. Compartments are fundamental to that process. Most resources can be moved between compartments. However, it's important to think through your compartment design for your organization up front, before implementing anything. For more information, see Setting Up Your Tenancy.
The Console is designed to display your resources by compartment within the current region. When you work with your resources in the Console, you must choose which compartment to work in from a list on the page. That list is filtered to show only the compartments in the tenancy that you have permission to access. If you're an administrator, you'll have permission to view all compartments and work with any compartment's resources, but if you're a user with limited access, you probably won't.
Compartments are tenancy-wide, across regions. When you create a compartment, it is available in every region that your tenancy is subscribed to. You can get a cross-region view of your resources in a specific compartment with the compartment explorer. See Viewing All Resources in a Compartment.
You can create subcompartments in compartments to create hierarchies that are six levels deep.
NEW QUESTION # 62
You have an application that requires a shared file system. Which of the following services would you use?
- A. Archive Storage
- B. Block Volume
- C. File Storage
- D. Object Storage
Answer: C
Explanation:
Explanation
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 also access a file system from outside the VCN using Oracle Cloud Infrastructure FastConnect and Internet Protocol security (IPSec) virtual private network (VPN).
Large Compute clusters of thousands of instances can use the File Storage service for high-performance shared storage. Storage provisioning is fully managed and automatic as your use scales from a single byte to exabytes without upfront provisioning.
The File Storage service supports the Network File System version 3.0 (NFSv3) protocol. The service supports the Network Lock Manager (NLM) protocol for file locking functionality.
Oracle Cloud Infrastructure File Storage employs 5-way replicated storage, located in different fault domains, to provide redundancy for resilient data protection. Data is protected with erasure encoding.
The File Storage service uses the "eventual overwrite" method of data eradication. Files are created in the file system with a unique encryption key. When you delete a single file, its associated encryption key is eradicated, making the file inaccessible. When you delete an entire file system, the file system is marked as inaccessible. The service systematically traverses deleted files and file systems, frees all the used space, and eradicates all residual files.
Use the File Storage service when your application or workload includes big data and analytics, media processing, or content management, and you require Portable Operating System Interface (POSIX)-compliant file system access semantics and concurrently accessible storage. The File Storage service is designed to meet the needs of applications and users that need an enterprise file system across a wide range of use cases, including the following:
NEW QUESTION # 63
Which pricing model is NOT supported by Oracle Cloud Infrastructure?
- A. Bring your own license
- B. Pay-as-you-go
- C. Universal Credits - Monthly Flex
- D. Reserved Infrastructure
Answer: D
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.
Reference:
https://www.oracle.com/in/cloud/bring-your-own-license/faq/universal-credit-pricing.html OCI doesn't offer Reserved instances.
Enterprise users and technology vendors alike require cost predictability to plan their budgets and run their business. The cost for running applications, databases, and large workloads in the cloud can be extremely difficult to forecast leading to unforeseen expenses. Not with Oracle Cloud. Oracle has simple rate structures that eliminate the cost surprises associated with hard-to-estimate usage elements like data egress and storage performance. Oracle also charges the same rates for all regions, so going global on Oracle Cloud means no hidden cost variances. Thus, Oracle's cloud will provide you with industry leading price-performance and tremendous business value.

NEW QUESTION # 66
Which three components are part of Oracle Cloud Infrastructure (OCI) identity and access management service?
- A. Policies
- B. Roles
- C. Compute Instances
- D. Virtual Cloud Networks
- E. Users
- F. Dynamic Groups
- G. Regional Subnets
Answer: A,E,F
Explanation:
Components of IAM
IAM 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. 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.

You can use the Console, CLI, or API to perform online resizing1.
NEW QUESTION # 69
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. Archive Storage
- B. Block Volume
- C. File 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 and 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 preserved 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. Network Address translation (NAT) Gateway
- B. Dynamic Routing gateway (DRG)
- C. Service gateway
- D. Internet gateway
Answer: C
Explanation:
A service gateway is the component of the Oracle Cloud Infrastructure Networking service that allows resources in a VCN to access Oracle Cloud Services without traversing the public internet. A service gateway provides a secure and private connection between a VCN and supported Oracle services, such as Object Storage, Autonomous Database, or Functions.
