Email alerts help users monitor and control their cloud spending.
NEW QUESTION # 57
Which three components are part of Oracle Cloud Infrastructure Identity and Access Management service?
- A. Users
- B. Roles
- C. Virtual Cloud Networks
- D. Regional Subnets
- E. Dynamic Groups
- F. Compute Instances
- G. Policies
Answer: A,E,G
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.

Which statement best describes the relationship Oracle Cloud infrastructure regions and Availability Domains?
- A. An Availability domain is a part of a region.
- B. Region and Availability Domains are the same thing.
- C. Availability Domain exist independently regions.
- D. A region is a part of an Availability domain
Answer: A
Explanation:
An availability domain is a part of a region. A region is a localized geographic area composed of one or more availability domains. An availability domain is one or more data centers located within a region that have fault-tolerant power and network connectivity. Availability domains are isolated from each other within a region, which provides protection from failures that affect multiple data centers at once.

NEW QUESTION # 63
Which statement is NOT valid regarding the Oracle Cloud Infrastructure (OCI) Block Volume service?
- A. You can increase the size of a block volume.
- B. You can decrease the size of a blockvolume.
- C. You can expand an existing block volume in place with online resizing.
- D. You can clone an existing block volume to a new, larger volume.
Answer: B
Explanation:
This statement is not valid regarding the OCI Block Volume service. You cannot decrease the size of a block volume once it is created. You can only increase the size of a block volume, either by creating a new, larger volume from a backup or a clone of the original volume, or by expanding an existing block volume in place with online resizing12 The other statements are valid regarding the OCI Block Volume service. You can expand an existing block volume in place with online resizing, which allows you to increase the size and performance of a block volume without detaching it from an instance or interrupting I/O operations. You can also clone an existing block volume to a new, larger volume, which creates an exact point-in-time copy of the source volume and preserves all the data and properties of the source volume, except for the size and performance. You can also increase the size of a block volume by creating a new, larger volume from a backup of the original volume, which restores all the data from the backup to a new volume with a different size and performance12
NEW QUESTION # 64
Which TWO features can be used to manage cost In an Oracle Cloud Infrastructure (OCI) tenancy?
(Choose all correct answers)
- A. Compartment Quotas
- B. Health Checks
- C. Account Controller
- D. Service Logs
- E. Budgets
Answer: A,E
Explanation:
Budgets and Compartment Quotas are two features that can be used to manage cost in an OCI tenancy. Budgets allow you to track and control your spending on OCI services by setting spending thresholds and getting alerts when you exceed them. Compartment Quotas allow you to limit the amount of resources that can be created or used in a compartment by setting quotas on specific resource types or metrics.

Which is a key benefit of using oracle cloud infrastructure autonomous data warehouse?
- A. Maintain root level acress to the underlying operating system
- B. Scale both CPU and Storage without downtime
- C. No username and password required
- D. Apply database patches as they become available
Answer: B
Explanation:
Oracle Autonomous Data Warehouse is a cloud data warehouse service that eliminates virtually all the complexities of operating a data warehouse and securing data. It automates provisioning, configuring, securing, tuning, scaling, patching, backing up, and repairing of the data warehouse. Unlike other "fully managed" cloud data warehouse solutions that only patch and update the service, it also features elastic, automated scaling, performance tuning, security, and a broad set of built-in capabilities that enable machine learning analysis, simple data loading, and data visualizations.
Data Warehouse uses continuous query optimization, table indexing, data summaries, and auto-tuning to ensure consistent high performance even as data volume and number of users grows. Autonomous scaling can temporarily increase compute and I/O by a factor of three to maintain performance. Unlike other cloud services which require downtime to scale, Autonomous Data Warehouse scales while the service continues to run.

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. File Storage Service
- B. API Gateway
- C. Container Engine for Kubernetes (OKE)
- D. Streaming Service
Answer: C
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.
