  ---

  Explanation/Reference:

  Oracle's mission is to build cloud infrastructure and platform services for your business to have effective and manageable security to run your mission-critical workloads and store your data with confidence. 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:

• Question 95:

  Which Oracle Cloud Infrastructure (OCI) service is best suited for running serverless apps?

  A. Oracle Functions
  B. Virtual Cloud Network
  C. Streaming
  D. Audit
  A. Oracle Functions

  ---

  Explanation/Reference:

  Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a- Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs. The serverless and elastic architecture of Oracle Functions means there's no infrastructure administration or software administration for you to perform. You don't provision or maintain compute instances, and operating system software patches and upgrades are applied automatically. Oracle Functions simply ensures your app is highly-available, scalable, secure, and monitored. With Oracle Functions, you can write code in Java, Python, Node, Go, and Ruby (and for advanced use cases, bring your own Dockerfile, and Graal VM). You can then deploy your code, call it directly or trigger it in response to events, and get billed only for the resources consumed during the execution. Oracle Functions is based on Fn Project. Fn Project is an open source, container native, serverless platform that can be run anywhere - any cloud or on-premises. Fn Project is easy to use, extensible, and performant. You can download and install the open source distribution of Fn Project, develop and test a function locally, and then use the same tooling to deploy that function to Oracle Functions. You can access Oracle Functions using the Console, a CLI, and a REST API. You can invoke the functions you deploy to Oracle Functions using the CLI or by making signed HTTP requests.

• Question 96:

  Which feature allows you to logically group and isolate your Oracle Cloud Infrastructure resources?

  A. Tenancy
  B. Identity and Access Management Groups
  C. Compartments
  D. Availability Domain
  C. Compartments

  ---

  Explanation/Reference:

  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 Reference:

  https://docs.cloud.oracle.com/en-us/iaas/tools/oci-cli/2.9.8/oci_cli_docs/cmdref/iam/compartment.html

• Question 97:

  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. Enables OCI Compute instance to connect to on-promises environments
  C. Enable OCI Compute instances to connect to the internal
  D. Enables OCI Compute instances to be reached from internet
  B. Enables OCI Compute instance to connect to on-promises environments

  ---

  Explanation/Reference:

  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).

• Question 98:

  Which pricing model is NOT supported by Oracle Cloud Infrastructure?

  A. Reserved Infrastructure
  B. Universal Credits - Monthly Flex
  C. Bring your own license
  D. Pay-as-you-go
  A. Reserved Infrastructure

  ---

  Explanation/Reference:

  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:

  1.

  Compute and compute support

  2.

  Automation

  3.

  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:

  1.

  Compute and compute support

  2.

  Automation

  3.

  Customers bring their on-premises license entitlement and get license support via their existing on- premises support contract.

  4.

  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.

• Question 99:

  Which option provides the best performance for running OLTP workloads in Oracle Cloud Infrastructure?

  A. OCI Exadata DB Systems
  B. OCI Autonomous Data Warehouse
  C. OCI Virtual Machine Instance
  D. OCI Dedicated Virtual Host
  A. OCI Exadata DB Systems

  ---

  Explanation/Reference:

  On an Exadata DB system, all databases share dedicated storage servers which include flash storage. By default, the databases are given equal priority with respect to these resources. The Exadata storage management software uses a first

  come, first served approach for query processing. If a database executes a major query that overloads I/O resources, overall system performance can be slowed down. The I/O Resource Management (IORM) allows you to assign priorities to

  your databases to ensure critical queries are processed first when workloads exceed their resource allocations. You assign priorities by creating directives that specify the number of shares for each database. The number of shares

  corresponds to a percentage of resources given to that database when I/O resources are stressed.

  Directives work together with an overall optimization objective you set for managing the resources.

  The following objectives are available:

  1) Auto - Recommended. IORM determines the optimization objective and continuously and dynamically determines the optimal settings, based on the workloads observed, and resource plans enabled.

  2) Balanced - For critical OLTP and DSS workloads. This setting balances low disk latency and high throughput. This setting limits disk utilization of large I/Os to a lesser extent than low latency to achieve a balance between good latency and

  good throughput.

  3) High throughput - For critical DSS workloads that require high throughput.

  4) Low latency - For critical OLTP workloads. This setting provides the lowest possible latency by significantly limiting disk utilization.
