NEW QUESTION 35
A customer wants to use Oracle Cloud Infrastructure (OCI) for storing application backups which can be stored based on business needs.
Which OCI storageservice can be used to meet the requirement?
- A. Archive Storage
- B. File Storage
- C. Object Storage (standard)
- D. Block Volume
Answer: C
Explanation:
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. Dataaccessibility 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 ofthe 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 CloudInfrastructure, 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 informationabout 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 36
Which statement is correct regarding the oracle cloud infrastructure Compute services?
- A. When you stop a compute instance, all data on the boot volume islost
- B. You can attach a maximum of one public to each compute instance
- C. You cannot attach a block volume to a compute instance
- D. You can launch either virtual machines or bare metal instances
Answer: D
Explanation:
Explanation
Oracle Cloud Infrastructure Compute lets you provision and manage compute hosts, known as instances You can launch instances as needed to meet your compute and application requirements. After you launch an instance, you can access it securely from your computer, restart it, attach and detach volumes,and terminate it when you're done with it. Any changes made to the instance's local drives are lost when you terminate it. Any saved changes to volumes attached to the instance are retained.
Oracle Cloud Infrastructure offers both bare metal and virtual machine instances:
1) Bare Metal: A bare metal compute instance gives you dedicated physical server access for highest performance and strong isolation.
2) Virtual Machine: A virtual machine (VM) is an independent computing environment that runs on top of physical bare metal hardware. The virtualization makes it possible to run multiple VMs that are isolated from each other. VMs are ideal for running applications that do not require the performance and resources (CPU, memory, network bandwidth, storage) of an entire physical machine.
An Oracle Cloud Infrastructure VM compute instance runs on the same hardware as a bare metal instance, leveraging the same cloud-optimized hardware, firmware, software stack, and networking infrastructure.

NEW QUESTION 38
What does compute instance horizonal scaling mean?
- A. adding additional compute instances
- B. changing compute instance size
- C. stopping/starting the instance
- D. backing up data to object storage
Answer: A
Explanation:
Explanation
Cloud Horizontal Scaling refersto provisioning additional servers to meet your needs, often splitting workloads between servers to limit the number of requests any individual server is getting. In a cloud-based environment, this would mean adding additional instances instead of movingto a larger instance size.
Cloud Vertical Scaling refers to adding more CPU or memory to an existing server, or replacing one server with a more powerful server.

Which Oracle Cloud Infrastructure (OCI) service can be used to protect sensitive and regulated data in OCI database services?
- A. Oracle Data Guard
- B. OCI OS management
- C. Oracle Data Safe
- D. OCI Audit
Answer: C
Explanation:
Explanation
Oracle Data Safe is a unified control center for your Oracle databases which helps you understand the sensitivity of your data, evaluate risks to data, mask sensitive data, implement andmonitor security controls, assess user security, monitor user activity, and address data security compliance requirements.
Whether you're using an Autonomous Database or an Oracle DB system, Oracle Data Safe delivers essential data security capabilities asa service on Oracle Cloud Infrastructure.
Features of Oracle Data Safe:
Oracle Data Safe provides the following set of features for protecting sensitive and regulated data in Oracle Cloud databases, all in a single, easy-to-use management console:
1) Security Assessment helps you assess the security of your cloud database configurations. It analyzes database configurations, user accounts, and security controls, and then reports the findings with recommendations for remediation activities that follow best practices to reduce or mitigate risk.
2) User Assessment helps you assess the security of your database users and identify high risk users. It reviews information about your users in the data dictionary on your target databases, and calculates a risk score for each user. For example, it evaluates the user types, how users are authenticated, the password policies assigned to each user, and how long it has been since each user has changed their password. It also provides a direct link to audit records related to each user. With this information, you can then deploy appropriate security controls and policies.
3) Data Discovery helps you find sensitive data in your cloud databases. You tell Data Discovery what kind of sensitive data to search for, and it inspects the actual data in your database and its data dictionary, and then returns to you a list of sensitive columns. By default, Data Discovery can search for a wide variety of sensitive data pertaining to identification, biographic, IT, financial, healthcare, employment, and academic information.
4) Data Masking provides a way for you to mask sensitive data so that the data is safe for non-production purposes. For example, organizations often need to create copies of their production data to support development and test activities. Simply copying the production data exposes sensitive data to new users. To avoid a security risk, you can use Data Masking to replace the sensitive data with realistic, but fictitious data.
5) Activity Auditing lets you audit user activity on your databases so you can monitor database usage and be alerted of unusual database activities.
NEW QUESTION 47
What is a key benefit of Oracle Cloud Infrastructure (OCI) Virtual Machine DB Systems?
- A. Support for RAC DB systems
- B. No need to create database Indices
- C. Automated disaster recovery
- D. Automated backups to OCI Block Volume
Answer: A
Explanation:
Explanation
There are two types of DB systems on virtual machines:
A 1-node virtual machine DB system consists of one virtual machine.
A 2-node virtual machine DB system consists of two virtual machines. (RAC) A virtual machine DB system database uses Oracle Cloud Infrastructure block storage instead of local storage.You specify a storage size when you launch the DB system, and you can scale up the storage as needed at any time.
For 1-node virtual machine DB systems, Oracle Cloud Infrastructure provides have a "fast provisioning" option that allows you to create your DB system using Logical Volume Manager as your storage management software.
Oracle CloudInfrastructure offers single-node DB systems on either bare metal or virtual machines, and
2-node RAC DB systems on virtual machines. If you need to provision a DB system for development or testing purposes, then a special fast provisioning single-node virtual machine system is available.
You can manage these systems by using the Console, the API, the Oracle Cloud Infrastructure CLI, the Database CLI (DBCLI), Enterprise Manager, Enterprise Manager Express, or SQL Developer.

NEW QUESTION 50
Which three components are part of Oracle Cloud Infrastructure Identity and Access Management service?
- A. Virtual Cloud Networks
- B. Regional Subnets
- C. Users
- D. Policies
- E. Roles
- F. Dynamic Groups
- G. Compute Instances
Answer: C,D,F
Explanation:
Explanation
IAM components are
RESOURCE
Thecloud 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 atthe 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 typeof 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 addressesfrom 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 resourcesfor 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 homeregion. 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'sIAM service. Oracle Cloud Infrastructure tenancies are federated with Oracle Identity Cloud Service by default.

Which is a key benefit of using oracle cloud infrastructure autonomous data warehouse?
- A. Maintain root level acress to the underlying operating system
- B. No username and password required
- C. Apply databasepatches as they become available
- D. Scale both CPU and Storage without downtime
Answer: D
Explanation:
Explanation
Oracle Autonomous Data Warehouse is a cloud data warehouse service that eliminates virtually all the complexities of operating a data warehouse andsecuring 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 whichrequire downtime to scale, Autonomous Data Warehouse scales while the service continues to run.
NEW QUESTION 53
Which Oracle Cloud Infrastructure (OCI) capability allows you to set up alerts to notify you if a budget forecast is to be exceeded or spending surpasses a certain amount?
- A. Budget
- B. Monitoring
- C. Cost Analysis
- D. Events
Answer: A
NEW QUESTION 54
Which Oracle Cloud Infrastructure (OCI) service can send you an alert when you might exceed your spending threshold?
- A. Streaming
- B. Monitoring
- C. Events
- D. Budgets
Answer: D
Explanation:
Budgets Overview: 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 hour in most regions, and every four hours in IAD. 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. Budget Concepts: The following concepts are essential to working with budgets:
BUDGETA monthly threshold you define for your Oracle Cloud Infrastructure spending. Budgets are set on cost-tracking tags or compartments and track all spending in the cost-tracking tag or compartment and any child compartments. Note The budget tracks spending in the specified target compartment, but you need to have permissions to manage budgets in the root compartment of the tenancy to create and use budgets.ALERTYou can define email alerts that get sent out for your budget. You can send a customized email message body with these alerts. Alerts are evaluated every hour in most regions (every four hours in IAD), and can be triggered when your actual or your forecasted spending hits either a percentage of your budget or a specified set amount.
