This Oracle Cloud Certification exam will take – on average – about one week of study to prepare for. Most people who seriously commit to their studies are ready to pass the exam within about four days.

什么是Oracle Cloud Infrastructure？ (What is Oracle Cloud Infrastructure?)

Oracle is a technology company that been around since the late 70s and is well known for building enterprise on-premises software and specifically their Oracle database.

Oracle是一家自70年代末以来一直存在的技术公司，以构建企业本地软件(尤其是其Oracle数据库)而闻名。

Oracle has its own cloud provider just like AWS, and they call their platform Oracle Cloud Infrastructure (OCI) – also know as Oracle Cloud.

Oracle与AWS一样拥有自己的云提供商，他们将其平台称为Oracle Cloud Infrastructure(OCI)–也称为Oracle Cloud。

Oracle does not have as many cloud services and cloud integration as AWS. But consider that Oracle was the second-largest software company by revenue and market share in 2019.

Oracle没有像AWS一样多的云服务和云集成。但请考虑一下Oracle在2019年的收入和市场份额方面是第二大软件公司。

Oracle has carved its niche in the cloud market by doing what they know best: providing rich cloud features around their Oracle database.

Oracle通过做自己最了解的事情，在云市场上立足了优势：围绕其Oracle数据库提供丰富的云功能。

Oracle Foundations助理认证 (The Oracle Foundations Associate Certification)

The Oracle Foundations Associate is the entry-level certification for Oracle Cloud Infrastructure.

Oracle Foundations Associate是Oracle Cloud Infrastructure的入门级认证。

This certification is very similar to the AWS Certified Cloud Practitioner. It focuses on getting you familiar with:

该认证与AWS Certified Cloud Practitioner非常相似。它着重于使您熟悉：

Cloud Concepts
云概念
Oracle's Global Infrastructure

Oracle Cloud's Core Services (Computing, Storage, Databases, Networking)
Oracle Cloud的核心服务(计算，存储，数据库，网络)
Oracle Cloud's Billing and Pricing
Oracle Cloud的计费和定价

If you are new to the Cloud, then you can pass exam this with under a week of study.

如果您不熟悉云，则可以在不到一周的学习时间内通过考试。

If you already hold the AWS Certified Cloud Practitioner, you could pass this exam with a few hours of study. You would just need to familiarize yourself with OCI's terminologies and some concepts around their account management and billing.

如果您已经拥有AWS认证的云实践者，则可以通过几个小时的学习来通过此考试。您只需要熟悉OCI的术语以及有关其帐户管理和计费的一些概念即可。

In this course, I'll show you a few examples of how AWS and OCI have very similar offerings in terms of technologies, but are just named differently. To name a few:

在本课程中，我将向您展示一些示例，这些示例说明AWS和OCI在技术方面如何提供非常相似的产品，但是名称却有所不同。仅举几例：

AWS Virtual Private Cloud (VPC) is the equivalent of Oracle Virtual Cloud Network (VCNs)
AWS虚拟私有云(VPC)等同于Oracle虚拟云网络(VCN)
AWS Availability Zones (AZs) is the equivalent of Oracle Availability Domains (ADs)
AWS可用区(AZ)等同于Oracle可用域(AD)
AWS Key Management System is the equivalent of Oracle Vault
AWS Key Management System等同于Oracle Vault
AWS S3 is the equivalent of Oracle Object Storage

AWS Elastic Block Store(EBS)等同于Oracle Block Storage
AWS EC2 is the equivalent of Oracle VM

The passing score for this exam is 68%. There are 60 questions – both multiple-choice and multiple-answer. This means you can afford to get about 19 questions wrong and still pass. Which is a considerable margin for error.

该考试的及格分数为68％。有60个问题-多项选择题和多项答案。这意味着您可以负担大约19个错误的问题，并且仍然可以通过。这是相当大的错误余量。

The exam fee generally costs $95 USD, and this Oracle Certification is valid for 1.5 years before you have to retake the exam.

考试费用通常为95美元，并且此Oracle认证的有效期为1.5年，您必须重新参加考试。
