What is a key benefit of Oracle Cloud Infrastructure (OCI) Virtual Machine DB Systems?
- A. Automated disaster recovery
- B. Automated backups to OCI Block Volume
- C. Support for RAC DB systems
- D. No need to create database Indices
Answer: C
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 Cloud Infrastructure 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 # 70
How will you configure high availability for an application In an Oracle Cloud Infrastructure (OCI) region with a single availability domain?
- A. Set up your application across multiple compartments.
- B. Set up your application across multiple Virtual Cloud Network (VCN).
- C. Set up your application across multiple fault domains.
- D. Divide region into multiple subregions.
Answer: C
Explanation:
Setting up your application across multiple fault domains is a way to configure high availability for an application in an OCI region with a single availability domain. A fault domain is a logical grouping of hardware and infrastructure within an availability domain that is designed to be isolated from failures in other fault domains. Fault domains let you distribute your instances so that they are not on the same physical hardware within a single availability domain. This reduces the impact of hardware failures, power outages, or network issues on your application availability and performance. Each availability domain has three fault domains, regardless of the number of availability domains in a region1

Which service is the most effective for moving large amounts of data from your on-premises to Oracle Cloud Infrastructure (OCI)?
- A. Internet Gateway
- B. Dynamic Routing Gateway
- C. Data Safe
- D. Data Transfer appliance
Answer: D
Explanation:
APPLIANCE-BASED DATA TRANSFER
You send your data as files on secure, high-capacity, Oracle-supplied storage appliances to an Oracle transfer site. Operators at the Oracle transfer site upload the data into your designated Object Storage bucket in your tenancy.
This solution supports data transfer when you are migrating a large volume of data and when using disks is not a practical alternative. You do not need to write any code or purchase any hardware. Oracle supplies the transfer appliance and software required to manage the transfer.
https://docs.cloud.oracle.com/en-us/iaas/Content/DataTransfer/Concepts/overview.htm Oracle Cloud Infrastructure Data Transfer Appliance securely moves terabytes or petabytes data between on-premise data centers and the cloud. The service reduces data migration times from weeks or months to just hours and is available for data import to the cloud and data export from the cloud.
NEW QUESTION # 74
Which TWO statements are true regarding Oracle Cloud Infrastructure (OCI) Regions?
(Choose al correct answers)
- A. Some regions only provide test/dev environments.
- B. Some regions provide multiple subregions.
- C. Some regions provide multiple availability domains.
- D. Some regions provide a single fault domain.
- E. Some regions provide a single availability domain.
Answer: C,E
Explanation:
These statements are true regarding OCI regions. A region is a localized geographic area that hosts one or more availability domains. An availability domain is one or more data centers that host OCI resources such as compute instances, block volumes, and subnets. Availability domains are isolated from each other, fault tolerant, and very unlikely to fail simultaneously1 Some regions provide multiple availability domains, while some regions provide a single availability domain. The number of availability domains per region varies depending on the region type and the customer demand. You can check the list of regions and their availability domains here: 2 Commercial regions: These are the standard regions that are available to all customers and offer a wide range of OCI services and features. Commercial regions can have one, two, or three availability domains per region.
Government regions: These are the regions that are dedicated to US government customers and meet specific compliance and security requirements. Government regions can have one or two availability domains per region.
Dedicated regions: These are the regions that are deployed within a customer's data center and provide a fully managed OCI environment that is consistent with the public cloud regions. Dedicated regions can have one or two availability domains per region.
The other statements are false regarding OCI regions. There is no concept of subregions in OCI. A region is composed of one or more availability domains, not subregions1 Regions do not only provide test/dev environments. Regions can host any type of workload or application, whether it is for production, development, testing, or disaster recovery purposes. Regions offer different performance levels, service levels, and pricing options to suit different customer needs and use cases1 Regions do not provide a single fault domain. A fault domain is a grouping of hardware and infrastructure within an availability domain that is designed to be isolated from failures in other fault domains. Fault domains let you distribute your instances so that they are not on the same physical hardware within a single availability domain. Each availability domain has three fault domains, regardless of the number of availability domains in a region3

NEW QUESTION # 77
Which Oracle Cloud Infrastructure (OCI) service can be used to protect sensitive and regulated data in OCI database services?
- A. Oracle Data Guard
- B. Oracle Data Safe
- C. OCI Audit
- D. OCI OS management
Answer: B
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 and monitor 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 as a 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 # 79
What is the frequency of OCI usage report generation?
- A. Annually
- B. Monthly
- C. Daily
- D. Weekly
Answer: C
Explanation:
A usage report is a comma-separated value (CSV) file that can be used to get a detailed breakdown of resources in Oracle Cloud Infrastructure for audit or invoice reconciliation.
The usage report is automatically generated daily, and is stored in an Oracle-owned Object Storage bucket. It contains one row per each Oracle Cloud Infrastructure resource (such as instance, Object Storage bucket, VNIC) per hour along with consumption information, metadata, and tags. Usage reports generally contain 24 hours of usage data, although occasionally a usage report may contain late-arriving data that is older than 24 hours.
Usage reports are retained for one year.

NEW QUESTION # 80
Which two should be considered when designing a fault tolerant solution in Oracle Cloud Infrastructure (OCI)?
- A. creating a manual cluster of compute instances
- B. performing data integrity check when using OCI File Storage Service
- C. using multiple OCI Availability Domains (AD), where available, to deploy your solution
- D. writing custom scripts that will monitor your solution
- E. ensuring your solution components are distributed across OCI Fault Domains
Answer: C,E
Explanation:
Creating a manual cluster of compute instances, and Writing custom scripts that will monitor your solution are not valid ways to ensure fault tolerance at all. Also, Performing Data Integrity check when using OCI File Storage Service is not valid since OCI takes care of it.
Therefore, we are left with:
1) Using multiple OCI Availibility Domains (AD), where available, to deploy your solution - Which is excellent because we have multiple AD's so that if one fails, we have a backup AD!
2) Ensuring your solution components are distributed across OCI Fault Domains - So that we can protect our deployment against unexpected power failures, AD failure etc.

- A. Network File System (NFS)
- B. Internet Small Computer Systems Interface (iSCSI)
- C. Server Message Block (SMB)
- D. File Transfer Protocol (FTP)
Answer: A
Explanation:
Network File System (NFS) is the file protocol that Oracle Cloud Infrastructure File Storage Service uses to enable file sharing across instances. NFS is a distributed file system protocol that allows a user on a client computer to access files over a network in a manner similar to how local storage is accessed. The File Storage service supports the NFS version 3.0 protocol with Network Lock Manager (NLM) for file locking functionality2.

NEW QUESTION # 83
Which resource do you manage in an Infrastructure-as-a-services (IAAS) offering?
- A. Servers
- B. Storage
- C. Operating system
- D. Network
Answer: C
Explanation:
Infrastructure as a service (IaaS) is a type of cloud service model in which computing resources are hosted in the cloud. Businesses can use the IaaS model to shift some or all of their use of on-premises or colocated data center infrastructure to the cloud, where it is owned and managed by a cloud provider. These infrastructure elements can include compute, network, and storage hardware as well as other components and software.
How Does IaaS Work?
In a typical IaaS model, a business-which can be of any size-consumes services like compute, storage, and databases from a cloud provider. The cloud provider offers those services by hosting hardware and software in the cloud. The business will no longer need to purchase and manage its own equipment, or space to host the equipment, and the cost will shift to a pay-as-you-go model. When the business needs less, it pays for less. And when it grows, it can provision additional computing resources and other technologies in minutes.
