Which Oracle Cloud Infrastructure (OCI) service can be used to protect sensitive and regulated data in OCI database services?
- A. Oracle Data Safe
- B. Oracle Data Guard
- C. OCI OS management
- D. OCI Audit
正解: A
解説:
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.
質問 18
Which resource do you manage in an Infrastructure-as-a-services (IAAS) offering?
- A. Storage
- B. Operating system
- C. Network
- D. Servers
正解: B
解説:
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.

正解: A
質問 20
Which feature allows you to logically group and isolate your Oracle Cloud Infrastructure resources?
- A. Compartments
- B. Tenancy
- C. Identity and Access Management Groups
- D. Availability Domain
正解: A
解説:
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

質問 21
What does compute instance vertical scaling mean?
- A. Adding additional compute instances
- B. Enabling Disaster recovery
- C. Changing to a large or smaller shape
- D. Providing Fault tolerance
正解: C
解説:
Changing the Shape of an Instance (Horizontal Scaling)
You can change the shape of a virtual machine (VM) instance without having to rebuild your instances or redeploy your applications. This lets you scale up your Compute resources for increased performance, or scale down to reduce cost.
Autoscaling (vertical scaling)
Autoscaling lets you automatically adjust the number of Compute instances in an instance pool based on performance metrics such as CPU utilization. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand.
As load increases, instances are automatically provisioned: the instance pool scales out. As load decreases, instances are automatically removed: the instance pool scales in.

質問 22
A customer wants to deploy a customized e commerce Web application using multiple virtual machines, block storage, databases, load balancer and web application firewall.
What cloud model can be used to host this application?
- A. Software as a Service (SaaS)
- B. Anything as a Service (XaaS)
- C. Infrastructure as a Service (IaaS)
- D. Platform as a Service (PaaS)
正解: C
解説:
https://www.oracle.com/cloud/what-is-iaas/
What Is IaaS?
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.
In the IaaS model, the cloud provider owns and operates the hardware and software and also owns or leases the data center. When you have an IaaS solution, you rent the resources like compute or storage, provision them when needed, and pay for the resources your organization consumes. For some resources such as compute, you'll pay for the resources you use. For others such as storage, you'll pay for capacity.
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.
In contrast, in a traditional on-premises scenario, a business manages and maintains its own data center. The business must invest in servers, storage, software, and other technologies, and hire an IT staff or contractors to purchase, manage, and upgrade all the equipment and licenses. The data center has to be built to meet peak demand, even though sometimes workloads decline and those resources stand idle. Conversely, if the business grows quickly, the IT department might struggle to keep up.
質問 23
Which statement below is not true for Oracle Cloud infrastructure Compartments?
- A. Each OCI resource belongs to a single compartment
- B. Resources and compartments can be added and deleted anytime
- C. Compartments cannot be nested
- D. Resources can be moved from one compartment to another
正解: C
解説:
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.
Reference:
https://docs.cloud.oracle.com/en-us/iaas/Content/Identity/Tasks/managingcompartments.htm When you first start working with Oracle Cloud Infrastructure, you need to think carefully about how you want to use compartments to organize and isolate your cloud resources. Compartments are fundamental to that process. Most resources can be moved between compartments. However, it's important to think through your compartment design for your organization up front, before implementing anything. For more information, see Setting Up Your Tenancy.
The Console is designed to display your resources by compartment within the current region. When you work with your resources in the Console, you must choose which compartment to work in from a list on the page. That list is filtered to show only the compartments in the tenancy that you have permission to access. If you're an administrator, you'll have permission to view all compartments and work with any compartment's resources, but if you're a user with limited access, you probably won't.
Compartments are tenancy-wide, across regions. When you create a compartment, it is available in every region that your tenancy is subscribed to. You can get a cross-region view of your resources in a specific compartment with the compartment explorer. See Viewing All Resources in a Compartment.
You can create subcompartments in compartments to create hierarchies that are six levels deep.

質問 36
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 region has a single Fault Domain.
- D. Each Fault Domain has multiple Availability Domains.
正解: B
解説:
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.
