Correct Answer: B

Fault domains in Oracle Cloud Infrastructure are used to distribute instances across different physical hardware within an availability domain. This helps in ensuring high availability and fault tolerance by reducing the impact of hardware failures on instances.

Correct Answer: BCE

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.

Correct Answer: A

Budgets can be used to set thresholds for 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.

Reference:

https://docs.cloud.oracle.com/en-us/iaas/Content/Billing/Concepts/billingoverview.htm 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.

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 Reference:

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.

Correct Answer: B

Archive storage is the most cost effective for archive data Reference:

https://www.oracle.com/cloud/storage/archive-storage.html 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 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 offsets the long lead time required to access the data.

2) 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. For more information, see Overview of Object Storage.

Correct Answer: B

You can think of a Dynamic Routing Gateway (DRG) as a virtual router that provides a path for private traffic (that is, traffic that uses private IPv4 addresses) between your VCN and networks outside the VCN's region. For example, if you use an IPSec VPN or Oracle Cloud Infrastructure FastConnect (or both) to connect your on-premises network to your VCN, that private IPv4 address traffic goes through a DRG that you create and attach to your VCN. For scenarios for using a DRG to connect a VCN to your on-premises network, see Networking Scenarios. For important details about routing to your on-premises network, see Routing Details for Connections to Your On-Premises Network. Also, if you decide to peer your VCN with a VCN in another region, your VCN's DRG routes traffic to the other VCN over a private backbone that connects the regions (without traffic traversing the internet). For information about connecting VCNs in different regions, see Remote VCN Peering (Across Regions).

Correct Answer: A

On an Exadata DB system, all databases share dedicated storage servers which include flash storage. By default, the databases are given equal priority with respect to these resources. The Exadata storage management software uses a first

come, first served approach for query processing. If a database executes a major query that overloads I/O resources, overall system performance can be slowed down. The I/O Resource Management (IORM) allows you to assign priorities to

your databases to ensure critical queries are processed first when workloads exceed their resource allocations. You assign priorities by creating directives that specify the number of shares for each database. The number of shares

corresponds to a percentage of resources given to that database when I/O resources are stressed.

Directives work together with an overall optimization objective you set for managing the resources.

The following objectives are available:

1) Auto - Recommended. IORM determines the optimization objective and continuously and dynamically determines the optimal settings, based on the workloads observed, and resource plans enabled.

2) Balanced - For critical OLTP and DSS workloads. This setting balances low disk latency and high throughput. This setting limits disk utilization of large I/Os to a lesser extent than low latency to achieve a balance between good latency and

good throughput.

3) High throughput - For critical DSS workloads that require high throughput.

4) Low latency - For critical OLTP workloads. This setting provides the lowest possible latency by significantly limiting disk utilization.
