NEW QUESTION 1
Your company has deployed a business critical application in Oracle Cloud Infrastructure. What should you do to ensure that your application has the highest level of resilience and availability?

• A. Deploy the application across multiple Availability Domains and Subnets
• B. Deploy the application across multiple Virtual Cloud Networks
• C. Deploy the application across multiple Regions and Availability Domains
• D. Deploy the application across multiple Availability Domains and Fault Domains

Answer: C

Explanation:
To design a high availability architecture, three key elements should be considered— redundancy, monitoring, and failover:
1) Redundancy means that multiple components can perform the same task. The problem of a single point of failure is eliminated because redundant components can take over a task performed by a component that has failed.
2) Monitoring means checking whether or not a component is working properly.
3) Failover is the process by which a secondary component becomes primary when the primary component fails.
The best practices introduced here focus on these three key elements. Although high availability can be achieved at many different levels, including the application level and the cloud infrastructure level, here we will focus on the cloud infrastructure level.
An Oracle Cloud Infrastructure region is a localized geographic area composed of one or more availability domains, each composed of three fault domains. High availability is ensured by a redundancy of fault domains within the availability domains.
An availability domain is one or more data centers located within a region. Availability domains are isolated from each other, fault tolerant, and unlikely to fail simultaneously. Because availability domains do not share physical infrastructure, such as power or cooling, or the internal availability domain network, a failure that impacts one availability domain is unlikely to impact the availability of others.
A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains let you distribute your instances so that they are not on the same physical hardware within a single availability domain. As a result, an unexpected hardware failure or a Compute hardware maintenance that affects one fault domain does not affect instances in other fault domains. You can optionally specify the fault domain for a new instance at launch time, or you can let the system select one for you.
All the availability domains in a region are connected to each other by a low-latency, high bandwidth network. This predictable, encrypted interconnection between availability domains provides the building blocks for both high availability and disaster recovery.

NEW QUESTION 2
Which feature allows you to logically group and isolate your Oracle Cloud Infrastructure resources?

• A. Tenancy
• B. Identity and Access Management Groups
• C. Compartments
• D. Availability Domain

Answer: C

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 3
Which three components are part of Oracle Cloud Infrastructure Identity and Access Management service?

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

Answer: BDG

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 4
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.

NEW QUESTION 5
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 6
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.

An Exadata DB system consists of a base system, quarter rack, half rack, or full rack of compute nodes and storage servers, tied together by a high-speed, low-latency InfiniBand network and intelligent Exadata software. You can configure automatic backups, optimize for different workloads, and scale up the system to meet increased demands.
Oracle now offers the Zero Downtime Migration service, a quick and easy way to move on-premises Oracle Databases and Oracle Cloud Infrastructure Classic databases to Oracle Cloud Infrastructure. You can migrate databases to the following types of Oracle Cloud Infrastructure systems: Exadata, Exadata Cloud@Customer, bare metal, and virtual machine.
Zero Downtime Migration leverages Oracle Active Data Guard to create a standby instance of your database in an Oracle Cloud Infrastructure system. You switch over only when you are ready, and your source database remains available as a standby. Use the Zero Downtime Migration service to migrate databases individually or
at the fleet level. See Move to Oracle Cloud Using Zero Downtime Migration for more information.

NEW QUESTION 9
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 10
You have an application that requires a shared file system. Which of the following services would you use?

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

Answer: A

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 shar 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 suppo the Network Lock Manager (NLM) protocol for file locking functionality.
Oracle Cloud Infrastructure File Storage employs 5-way replicated storage, located in different fault domain 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 fil 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 17
You have a mission-critical application which requires to be globally available at all times. Which deployment strategy should you adopt?

• A. Use multiple Fault Domains In each Availability Domain in each Region.
• B. Use multiple Availability Domains In one Region.
• C. Use multiple Fault Domains In one Region.
• D. Use multiple Fault Domains in any Availability Domain in multiple Regions.

Answer: A

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.
Regions are independent of other regions and can be separated by vast distances—across countries or even continents.
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.
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.
