Reference:
https://docs.cloud.oracle.com/en-us/iaas/Content/Network/Tasks/settingupIPsec.htm It is possible to set up a site-to-site Virtual Private Network (VPN) Connection between your on-premises network (a data center or corporate LAN) and your Oracle virtual cloud network (VCN) over a secure encrypted VPN. The VPN connection uses industry-standard IPSec protocols. The Oracle service that provides site-to-site connectivity is named VPN Connect (also referred to as an IPSec VPN).
NEW QUESTION # 87
Which three services Integrate with Oracle Cloud Infrastructure (OCI) Key Management?
- A. Identity and Access Management
- B. Functions
- C. Auto Scaling
- D. Block Volume
- E. Object Storage
- F. File Storage
Answer: D,E,F
Explanation:
DATA ENCRYPTION
Protect customer data at-rest and in-transit in a way that allows customers to meet their security and compliance requirements for cryptographic algorithms and key management The Oracle Cloud Infrastructure Block Volume service always encrypts all block volumes, boot volumes, and volume backups at rest by using the Advanced Encryption Standard (AES) algorithm with 256-bit encryption. By default all volumes and their backups are encrypted using the Oracle-provided encryption keys. Each time a volume is cloned or restored from a backup the volume is assigned a new unique encryption key.
The File Storage service encrypts all file system and snapshot data at rest. By default all file systems are encrypted using Oracle-managed encryption keys. You have the option to encrypt all of your file systems using the keys that you own and manage using the Vault service.
Object Storage employs 256-bit Advanced Encryption Standard (AES-256) to encrypt object data on the server. Each object is encrypted with its own data encryption key. Data encryption keys are always encrypted with a master encryption key that is assigned to the bucket. Encryption is enabled by default and cannot be turned off. By default, Oracle manages the master encryption key.

https://docs.cloud.oracle.com/en-us/iaas/Content/Object/Concepts/objectstorageoverview.htm
https://docs.cloud.oracle.com/en-us/iaas/Content/File/Concepts/filestorageoverview.htm Oracle Cloud Infrastructure Key Management is a managed service that enables you to encrypt your data using keys that you control.
IAM, Autoscaling and functions cannot be used with Key Management and hence are incorrect options.
NEW QUESTION # 88
Which Oracle cloud infrastructure capability can be used to protect against power failures within an availability Domain?
- A. Services Cells
- B. Top of Rack Switch
- C. Fault Domains
- D. Data Plane
Answer: C
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.
To control the placement of your compute instances, bare metal DB system instances, or virtual machine DB system instances, you can optionally specify the fault domain for a new instance or instance pool at launch time. If you don't specify the fault domain, the system selects one for you. Oracle Cloud Infrastructure makes a best-effort anti-affinity placement across different fault domains, while optimizing for available capacity in the availability domain. To change the fault domain for an instance, terminate it and launch a new instance in the preferred fault domain.
Use fault domains to do the following things:
Protect against unexpected hardware failures or power supply failures.
Protect against planned outages because of Compute hardware maintenance.

Which capability enables you to search, purchase, and start using software in your Oracle Cloud Infrastructure (OCI) tenancy?
- A. OCI Marketplace
- B. OCI Registry
- C. OCI Resource Manager
- D. OCI OS Management
Answer: A
Explanation:
Oracle Cloud Infrastructure Marketplace is an online store that offers solutions specifically for customers of Oracle Cloud Infrastructure. In the Oracle Cloud Infrastructure Marketplace catalog, you can find listings for two types of solutions from Oracle and trusted partners: images and stacks. These listing types include different categories of applications. Also, some listings are free and others require payment.
Images are templates of virtual hard drives that determine the operating system and software to run on an instance. You can deploy image listings on an Oracle Cloud Infrastructure Compute instance. Marketplace also offers stack listings. Stacks represent definitions of groups of Oracle Cloud Infrastructure resources that you can act on as a group. Each stack has a configuration consisting of one or more declarative configuration files. With an image or a stack, you have a customized, more streamlined way of getting started with a publisher's software.

NEW QUESTION # 92
What does compute instance horizonal scaling mean?
- A. stopping/starting the instance
- B. adding additional compute instances
- C. changing compute instance size
- D. backing up data to object storage
Answer: B
Explanation:
Cloud Horizontal Scaling refers to 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 moving to 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.
Reference:
https://cloudcheckr.com/cloud-cost-management/cloud-vs-data-center-what-is-scalability-in-cloud-computing/ Horizontal scaling means that you scale by adding more machines into your pool of resources whereas Vertical scaling means that you scale by adding more power (CPU, RAM) to an existing machine.
An easy way to remember this is to think of a machine on a server rack, we add more machines across the horizontal direction and add more resources to a machine in the vertical direction.
With horizontal-scaling it is often easier to scale dynamically by adding more machines into the existing pool - Vertical-scaling is often limited to the capacity of a single machine, scaling beyond that capacity often involves downtime and comes with an upper limit.
NEW QUESTION # 93
Which of these Is defined as a qualifier used for filtering group metric data presented in the Oracle Cloud Infrastructure (OCI) Monitoring service? ^
- A. Namespaces
- B. Dimensions
- C. Indicators
- D. Facts
Answer: B
NEW QUESTION # 94
What purpose does an Oracle Cloud Infrastructure (OCI) Dynamic Routing Gateway Serve?
- A. Enables OCI Compute Instance to privately connect to OCI Object Storage
- B. Enable OCI Compute instances to connect to the internal
- C. Enables OCI Compute instances to be reached from internet
- D. Enables OCI Compute instance to connect to on-promises environments
Answer: D
Explanation:
You can think of a Dynamic Routing Gateway (DRG) as a virtual router that provides a path for private traffic (that is, traffic that uses private IPv4 addresses) between your VCN and networks outside the VCN's region.
For example, if you use an IPSec VPN or Oracle Cloud Infrastructure FastConnect (or both) to connect your on-premises network to your VCN, that private IPv4 address traffic goes through a DRG that you create and attach to your VCN. For scenarios for using a DRG to connect a VCN to your on-premises network, see Networking Scenarios. For important details about routing to your on-premises network, see Routing Details for Connections to Your On-Premises Network.
Also, if you decide to peer your VCN with a VCN in another region, your VCN's DRG routes traffic to the other VCN over a private backbone that connects the regions (without traffic traversing the internet). For information about connecting VCNs in different regions, see Remote VCN Peering (Across Regions).
NEW QUESTION # 95
Which pricing model is NOT supported by Oracle Cloud Infrastructure?
- A. Pay-as-you-go
- B. Universal Credits - Monthly Flex
- C. Reserved Infrastructure
- D. Bring your own license
Answer: C
Explanation:
The available purchase models are:
Pay As You Go (PAYG): Billed in arrears based on consumption. Recommended for organizations who are trying new services, rapid prototyping, or for elastic scaling.
Monthly Flex: Billed in advance with a 12-month minimum. Use monthly or forfeit that month's credits. Recommended for customers with predictable production workloads or large long-running applications, such as HR, payroll, analytics, and more. Monthly Flex maximizes cost reduction with predictable monthly spend, similar to your monthly phone plan. Delivers faster time to market by offering customers the choice of using any IaaS and PaaS services.
Oracle's current PaaS offering is "license-included PaaS." It includes:
* Compute and compute support
* Automation
* License entitlement and license support
Bring your own license
BYOL stands for "bring your own license." Previously, you could bring your own licenses to Oracle IaaS, but to get the benefits of PaaS automation, you couldn't leverage existing licenses. This has been changed. We're offering Oracle BYOL to PaaS, enabling our customers to leverage their investment in existing on-premises licenses in their journey to the cloud.
Oracle BYOL to PaaS includes:
* Compute and compute support
* Automation
* Customers bring their on-premises license entitlement and get license support via their existing on-premises support contract.
* As customers leverage their existing on-premises license entitlement, they can move to the cloud at a lower cost.
Reference:
https://www.oracle.com/in/cloud/bring-your-own-license/faq/universal-credit-pricing.html OCI doesn't offer Reserved instances.
Enterprise users and technology vendors alike require cost predictability to plan their budgets and run their business. The cost for running applications, databases, and large workloads in the cloud can be extremely difficult to forecast leading to unforeseen expenses. Not with Oracle Cloud. Oracle has simple rate structures that eliminate the cost surprises associated with hard-to-estimate usage elements like data egress and storage performance. Oracle also charges the same rates for all regions, so going global on Oracle Cloud means no hidden cost variances. Thus, Oracle's cloud will provide you with industry leading price-performance and tremendous business value.

NEW QUESTION # 100
Which statement is correct regarding the oracle cloud infrastructure Compute services?
- A. When you stop a compute instance, all data on the boot volume is lost
- B. You can launch either virtual machines or bare metal instances
- C. You cannot attach a block volume to a compute instance
- D. You can attach a maximum of one public to each compute instance
Answer: B
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 # 101
Which statement about Oracle Cloud Infrastructure (OCI) shared security model is true?
- A. You are not responsible for any aspect of security in OCI.
- B. You are responsible for managing security controls within the physical OCI network.
- C. You are responsible for securing all data that you place in OCI
- D. You are responsible for securing the hypervisor within OCI Compute service.
Answer: C
Explanation:
Oracle Cloud Infrastructure offers best-in-class security technology and operational processes to secure its enterprise cloud services. However, for you to securely run your workloads in Oracle Cloud Infrastructure, you must be aware of your security and compliance responsibilities. By design, Oracle provides security of cloud infrastructure and operations (cloud operator access controls, infrastructure security patching, and so on), and you are responsible for securely configuring your cloud resources. Security in the cloud is a shared responsibility between you and Oracle.
In a shared, multi-tenant compute environment, Oracle is responsible for the security of the underlying cloud infrastructure (such as data-center facilities, and hardware and software systems) and you are responsible for securing your workloads and configuring your services (such as compute, network, storage, and database) securely.
In a fully isolated, single-tenant, bare metal server with no Oracle software on it, your responsibility increases as you bring the entire software stack (operating systems and above) on which you deploy your applications. In this environment, you are responsible for securing your workloads, and configuring your services (compute, network, storage, database) securely, and ensuring that the software components that you run on the bare metal servers are configured, deployed, and managed securely.
More specifically, your and Oracle's responsibilities can be divided into the following areas:
Identity and Access Management (IAM): As with all Oracle cloud services, you should protect your cloud access credentials and set up individual user accounts. You are responsible for managing and reviewing access for your own employee accounts and for all activities that occur under your tenancy. Oracle is responsible for providing effective IAM services such as identity management, authentication, authorization, and auditing.
Workload Security: You are responsible for protecting and securing the operating system and application layers of your compute instances from attacks and compromises. This protection includes patching applications and operating systems, operating system configuration, and protection against malware and network attacks. Oracle is responsible for providing secure images that are hardened and have the latest patches. Also, Oracle makes it simple for you to bring the same third-party security solutions that you use today.
Data Classification and Compliance: You are responsible for correctly classifying and labeling your data and meeting any compliance obligations. Also, you are responsible for auditing your solutions to ensure that they meet your compliance obligations.
Host Infrastructure Security: You are responsible for securely configuring and managing your compute (virtual hosts, containers), storage (object, local storage, block volumes), and platform (database configuration) services. Oracle has a shared responsibility with you to ensure that the service is optimally configured and secured. This responsibility includes hypervisor security and the configuration of the permissions and network access controls required to ensure that hosts can communicate correctly and that devices are able to attach or mount the correct storage devices.
Network Security: You are responsible for securely configuring network elements such as virtual networking, load balancing, DNS, and gateways. Oracle is responsible for providing a secure network infrastructure.
Client and Endpoint Protection: Your enterprise uses various hardware and software systems, such as mobile devices and browsers, to access your cloud resources. You are responsible for securing all clients and endpoints that you allow to access Oracle Cloud Infrastructure services.
Physical Security: Oracle is responsible for protecting the global infrastructure that runs all of the services offered in Oracle Cloud Infrastructure. This infrastructure consists of the hardware, software, networking, and facilities that run Oracle Cloud Infrastructure services.
