NEW QUESTION 21
Which feature allows you to logically group and isolate your Oracle Cloud Infrastructure resources?
- A. Compartments
- B. Identity and Access Management Groups
- C. Availability Domain
- D. Tenancy
Answer: A
Explanation:
Explanation
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

NEW QUESTION 23
After Signing up for a new Oracle cloud Infrastructure tenancy, what would you subscribe to in order to deploy infrastructure and services in different parts of the world?
- A. Fault Domains
- B. Pay as you go pricing
- C. Availability Domain
- D. Region
Answer: D
Explanation:
Explanation
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.
Oracle is adding multiple cloud regions around the world to provide local access to cloud resources for our customers. To accomplish this quickly, we've chosen to launch regions in new geographies with one availability domain.
As regions require expansion, we have the option to add capacity to existing availability domains, to add additional availability domains to an existing region, or to build a new region. The expansion approach in a particular scenario is based on customer requirements as well as considerations of regional demand patterns and resource availability.
For any region with one availability domain, a second availability domain or region in the same country or geo-political area will be made available within a year to enable further options for disaster recovery that support customer requirements for data residency where they exist.

Which two security capabilities are offered by Oracle Cloud Infrastructure?
- A. Always on data encryption for data-at-rest.
- B. Managed Active Directory service
- C. Certificate Management service
- D. Key Management service
- E. Captcha
Answer: A,D
Explanation:
Explanation
Oracle Cloud Infrastructure's security approach is based on seven core pillars. Each pillar has multiple solutions designed to maximize the security and compliance of the platform and to help customers to improve their security posture.
High Availability: Offer fault-independent data centers that enable high-availability scale-out architectures and are resilient against network attacks, ensuring constant uptime in the face of disaster and security attack.
Customer Isolation: Allow customers to deploy their application and data assets in an environment that commits full isolation from other tenants and Oracle's staff.
Data Encryption: Protect customer data at-rest and in-transit in a way that allows customers to meet their security and compliance requirements with respect to cryptographic algorithms and key management.
Security Controls: Offer customers effective and easy-to-use application, platform, and network security solutions that allow them to protect their workloads, have a secure application delivery using a global edge network, constrain access to their services, and segregate operational responsibilities to reduce the risk associated with malicious and accidental user actions.
Visibility: Offer customers comprehensive log data and security analytics that they can use to audit and monitor actions on their resources, allowing them to meet their audit requirements and reduce security and operational risk.
Secure Hybrid Cloud: Enable customers to use their existing security assets, such as user accounts and policies, as well as third-party security solutions, when accessing their cloud resources and securing their data and application assets in the cloud.
Verifiably Secure Infrastructure: Follow rigorous processes and use effective security controls in all phases of cloud service development and operation. Demonstrate adherence to Oracle's strict security standards through third-party audits, certifications, and attestations. Help customers demonstrate compliance readiness to internal security and compliance teams, their customers, auditors, and regulators.
NEW QUESTION 27
Which service is the most effective for moving large amounts of data from your on-premises to Oracle Cloud Infrastructure (OCI)?
- A. Dynamic Routing Gateway
- B. Internet Gateway
- C. Data Transfer appliance
- D. Data Safe
Answer: C
Explanation:
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.

NEW QUESTION 35
Which capability can be used to protect against unexpected hardware or power supply failures within an availability domain?
- A. Top of Rack Switches
- B. Compartments
- C. Fault Domains
- D. Power Distribution Units
Answer: C
Explanation:
Explanation
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.
Usually fault domains to do the following things:
1) Protect against unexpected hardware failures or power supply failures.
2) Protect against planned outages because of Compute hardware maintenance.
NEW QUESTION 36

IAM DYNAMIC GROUP is 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.

NEW QUESTION 40
Which OCI storage service does not provide encryption for data at rest?
- A. Local NVMe
- B. Object Storage
- C. File Storage
- D. Block Volume
Answer: A
Explanation:
Explanation
NVMe stands for non-volatile memory express. It is a storage protocol created to fasten the transfer of data between enterprise and client systems and solid-state drives (SSDs) over a computer's high-speed Peripheral Component Interconnect Express bus. The characteristics are:
1) Local NVMe is NVMe SSD-based temporary storage.
2) It is the locally-attached NVMe devices to the OCI compute instance
3) It is used very high storage performance requirements, lots of throughput, lots of IOPS, local storage and when you don't want to go out on network
4) Oracle does not protect in any way through RAID, or snapshots, or backup out of the box and data is not encrypted at rest.
