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.

Correct Answer: ADE

You can create and manage resources in the following ways: Oracle Cloud Infrastructure Console The Console is an intuitive, graphical interface that lets you create and manage your instances, cloud networks, and storage volumes, as well as your users and permissions. See Using the Console. Oracle Cloud Infrastructure APIs The Oracle Cloud Infrastructure APIs are typical REST APIs that use HTTPS requests and responses. See API Requests. SDKs Several Software Development Kits are available for easy integration with the Oracle Cloud Infrastructure APIs, including SDKs for Java, Ruby, and Python. For more information, see Developer Resources. Command Line Interface (CLI) You can use a command line interface with some services. For more information, see Developer Resources. Terraform Oracle supports Terraform. Terraform is "infrastructure-as-code" software that allows you to define your infrastructure resources in files that you can persist, version, and share. For more information, see Getting Started with the Terraform Provider. Ansible Oracle supports the use of Ansible for cloud infrastructure provisioning, orchestration, and configuration management. Ansible allows you to automate configuring and provisioning your cloud infrastructure, deploying and updating software assets, and orchestrating your complex operational processes. For more information, see Getting Started with Ansible for Oracle Cloud Infrastructure. Resource Manager Resource Manager is an Oracle Cloud Infrastructure service that allows you to automate the process of provisioning your Oracle Cloud Infrastructure resources. It helps you install, configure, and manage resources using the "infrastructure- as-code" model. For more information, see Overview of Resource Manager.

Correct Answer: A

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.

Correct Answer: C

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

Correct Answer: AE

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. We can use 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 Reference: https://docs.cloud.oracle.com/en-us/iaas/Content/General/Concepts/regions.htm

Correct Answer: B

A shape is a template that determines the number of CPUs, amount of memory, and other resources that

are allocated to an instance.

The network bandwidth is directly proportional to the number of OCPUs in the instance shape!

Correct Answer: A

Cost Analysis is an easy-to-use visualization tool to help you track and optimize your Oracle Cloud Infrastructure spending, allows you to generate charts, and download accurate, reliable tabular reports of aggregated cost data on your Oracle Cloud Infrastructure consumption. Use the tool for spot checks of spending trends and for generating reports

Correct Answer: C

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.

Correct Answer: C

Oracle Cloud Infrastructure Identity and Access Management (IAM) lets you control who has access to your cloud resources. You can control what type of access a group of users have and to which specific resources. This section gives you an overview of IAM components and an example scenario to help you understand how they work together.
