I. Introduction

- Overview of the AWS Certified Cloud Practitioner exam and its importance for cloud professionals

People who can successfully demonstrate a broad understanding of the AWS Cloud, independent of a specific work description, are those who should take the AWS Certified Cloud Practitioner (CLF-CO1) exam.

Candidate target description:

The ideal applicant should have been actively using the AWS Cloud for six months, or the equivalent, and should be familiar with its design, implementation, and/or operations. Candidates will show that they have a solid understanding of AWS Cloud solutions.

Recommended AWS knowledge：

• AwS Cloud concepts
• Security and compliance within the AWS Cloud
• Understanding of the core AWS services
• Understanding of the economics of the AwS Cloud

The AWS Certified Cloud Practitioner certifies a person's high-level, fundamental knowledge of the AWS Cloud, its services, and its lingo. If you're transitioning to a cloud profession and have no prior IT or cloud experience, or if you're a line-of-business employee wishing to gain a basic understanding of the cloud, here is a fantastic place to start your AWS Certification journey.

A high degree of expertise in the AWS Cloud, services, and terminology is validated by earning this certification. Candidates transitioning to cloud computing from non-IT backgrounds might use this certification as a stepping stone.

The average annual salary for an Entry Level Aws Cloud Practitioner in the United States as of July 5, 2024, is $85,866. In case you need a quick pay estimator, that comes out to about $41.28 per hour. This amounts to $7,155 per month or $1,651 each week.

AWS Cloud Practitioner Certification Will Put Your Career on Cloud Nine! You can put a stamp on your abilities to create and deploy carefully-architected solutions on AWS by earning an AWS cloud practitioner certification. It increases the trust that recruiting firms have in your abilities, which improves your career prospects.

- Exam Objectives and Question Formats

Learning Intentions

• Recognize the AWS compute services that are offered and how to start an EC2 instance.
• Find out more about AWS's auto-scaling and load balancing.
• Learn about the different storage options provided by AWS and gain practical knowledge of Amazon S3 and Amazon Elastic Block Store (EBS).

Exam Format

Knowing the structure of the AWS Cloud Practitioner Exam is crucial to developing a strategy. It can undoubtedly aid in your exam performance. Additionally, being aware of the type of exam questions to expect makes it easier for you to manage your time. Without further ado, let's have a look at the AWS Cloud Practitioner exam's format.

· The overall number of questions on the AWS Cloud Practitioner Exam is between 65 and 68. The exam will offer candidates a total of 90 minutes to finish it.

· Additionally, the exam will be provided in four other languages for the convenience of candidates with various mother tongues. English, Japanese, Korean, and Simplified Chinese are also included in this list.

Additionally, the AWS Cloud Practitioner exam includes two different sorts of questions, namely:

· Multiple-choice questions only allow for one correct solution, with the other three serving as distractions.

· Multiple-choice questions have two or more correct answers out of a possible selection of five or more.

· Negative Marking - There won't be any negative marking if the response you indicated is wrong. This indicates that you can attempt to estimate the right response. If your speculation is accurate, you'll end up receiving higher grades. If not, there is no harm because there is no punishment for giving incorrect replies.

· Unscored Content - You may encounter some ungraded questions while taking your exam. Your scores won't change whether you attempt or don't attempt these questions in any way. These ungraded questions are merely included on the exam to collect data statistically.

There are two types of questions on the exam:

• Multiple choice: Has one correct response and three incorrect responses (distractors)
• Multiple response: Has two or more correct responses out of five or more response optionsSelect one or more responses that best complete the statement or answer the question. Distractors, orincorrect answers, are response options that a candidate with incomplete knowledge or skill might choose.Distractors are generally plausible responses that match the content area.

Unanswered questions are scored as incorrect; there is no penalty for guessing.The exam includes 50 questions that will affect your score.

Unscored content

The exam includes 15 unscored questions that do not affect your score.AWS collects information about candidate performance on these unscored questions to evaluate these questions for future use as scored questions.These unscored questions are not identified on the exam.

Exam results

The AWS Certified Cloud Practitioner exam is a pass or fail exam. The exam is scored against a minimum standard established by AWS professionals who follow certification industry best practices and guidelines.Your results for the exam are reported as a scaled score of 100-1,000. The minimum passing score is 700.Your score shows how you performed on the exam as a whole and whether or not you passed.

Your score report may contain a table of classifications of your performance at each section level.This information is intended to provide general feedback about your exam performance.The exam uses a compensatory scoring model, which means that you do not need to achieve a passing score in each section. You need to pass only the overall exam.

Each section of the exam has a specific weighting, so some sections have more questions than others. The table contains general information that highlights your strengths and weaknesses. Use caution when interpreting section-level feedback.
