NEW QUESTION # 87
You have a mission-critical application which requires to be globally available at all times.
Which deployment strategy should you adopt?
- A. Use multiple Fault Domains in any Availability Domain in multiple Regions.
- B. Use multiple Fault Domains In one Region.
- C. Use multiple Fault Domains In each Availability Domain in each Region.
- D. Use multiple Availability Domains In one Region.
Answer: C
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.
Regions are independent of other regions and can be separated by vast distances-across countries or even continents.
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.
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.

NEW QUESTION # 88
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 a single fault domain.
- D. Some regions provide multiple availability domains.
- E. Some regions provide a single availability domain.
Answer: D,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 # 89
Which OCI storage service does not provide encryption for data at rest?
- A. File Storage
- B. Object Storage
- C. Block Volume
- D. Local NVMe
Answer: D
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.

NEW QUESTION # 91
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. API Gateway
- B. Streaming Service
- C. File Storage Service
- D. Container Engine for Kubernetes (OKE)
Answer: D
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.
NEW QUESTION # 92
Which service is the most effective for moving large amounts of data from your on-premises to Oracle Cloud Infrastructure (OCI)?
- A. Data Transfer appliance
- B. Dynamic Routing Gateway
- C. Data Safe
- D. Internet Gateway
Answer: A
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 # 93

- C. Streaming Service
- D. Container Engine for Kubernetes (OKE)
Answer: A
NEW QUESTION # 95
You run 5 Oracle Cloud Infrastructure (OCI) Virtual Machine instances on an OCI dedicated virtual host. How will this deployment be billed?
- A. The dedicated virtual machine host and the boot volumes of each instance will be billed
- B. All 5 instances will be billed on the basis of the number of OCPUs
- C. The dedicated virtual machine host all 5 instances, and the boot volume of each instance will be billed
- D. Only the dedicated virtual machine host will be billed
Answer: A
Explanation:
You must create a dedicated virtual machine host before you can place any instances on it. When creating the dedicated virtual machine host, you select an availability domain and fault domain to launch it in. All the VM instances that you place on the host will subsequently be created in this availability domain and fault domain. You also select a compartment when you create the dedicated virtual machine host, but you can move the host to a new compartment later without impacting any of the instances placed on it. You can also create the instances in a different compartment than the dedicated virtual machine host, or move them to difference compartments after they have been launched.
You are billed for the dedicated virtual machine host as soon as you create it, but you are not billed for any of the individual VM instances you place on it. You will still be billed for image licensing costs if they apply to the image you are using for the VM instances.

What is a key benefit of Oracle Cloud Infrastructure (OCI) Virtual Machine DB Systems?
- A. Automated disaster recovery
- B. No need to create database Indices
- C. Automated backups to OCI Block Volume
- D. Support for RAC DB systems
Answer: D
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.

Which TWO are valid regarding the Oracle Cloud Infrastructure (OCI) Logging service?
(Choose all correct Answers)
- A. It enables you to monitor cloud resources using metrics and alarms.
- B. It can index, enrich, and aggregate log data from application.
- C. It enables you to analyze cloud resources using custom metrics.
- D. It is a centralized single pane of glass for all logs in a tenancy.
- E. It can analyze critical diagnostic information that describes how resources are performing and being accessed.
Answer: D,E
Explanation:
OCI Logging service is a highly scalable and fully managed service that allows you to access logs from OCI resources. OCI Logging allows three kinds of logs: Audit, service, and custom logs. You can find more details for each of these logs in the documentation3 OCI Logging service is a centralized single pane of glass for all logs in a tenancy. You can view and search logs on the Logging Search page. When searching logs, you can correlate across many logs simultaneously. For example, you can view results from multiple logs, multiple log groups, or even an entire compartment with one query3 OCI Logging service can index, enrich, and aggregate log data from application. Custom logs are logs that contain diagnostic information from custom applications, other cloud providers, or an on-premises environment. Custom logs can be ingested through the API, or by configuring the Unified Monitoring Agent. You can configure an OCI compute instance/resource to directly upload Custom Logs through the Unified Monitoring Agent. Custom logs are supported in both a virtual machine and bare metal scenario3 OCI Logging service can analyze critical diagnostic information that describes how resources are performing and being accessed. These logs include audit logs related to events emitted by the OCI Audit service, such as API calls or console actions performed by users or services in your tenancy; service logs emitted by OCI native services, such as API Gateway, Events, Functions, Load Balancer, Object Storage, and VCN Flow Logs; and custom logs from your own applications or sources3
NEW QUESTION # 102
Which statement is NOT true about compartments in Oracle Cloud infrastructure?
- A. Components provide a way to store and manage encryption keys and secrets.
- B. Compartments can be nested to create a hierarchy.
- C. Identity and Access Management (IAM) policies can be written to grant access to resources in specific compartments.
- D. Compartments are global resource.
Answer: A
Explanation:
Compartments do not provide a way to store and manage encryption keys and secrets in Oracle Cloud Infrastructure. Compartments are logical containers that help users organize and isolate their cloud resources. Compartments can be nested to create a hierarchy that reflects the structure of an organization or project. To store and manage encryption keys and secrets, users can use the Oracle Cloud Infrastructure Vault service, which is a fully managed service that provides centralized management of encryption keys, secrets, and certificates.
