Читать книгу AWS Certified SysOps Administrator Official Study Guide - Cole Stephen - Страница 16

Each chapter in this book ends with a list of important concepts to study. This list is not comprehensive, as the material is covered in the chapter itself, but the concepts are a good place to do a quick review of important testing areas. Every chapter ends with a useful tip from AWS trainers who specialize in helping people pass their certification exams. Look to these tips for good test-taking strategies that complement your core AWS knowledge.

Key Pieces to Study

Understand how AWS Regions and Availability Zones work to provide geographic distribution of services. Know how to deploy your environment across multiple Availability Zones and how to use Amazon CloudFront to take advantage of AWS edge locations.

Understand the shared responsibility model and that it is foundational to understanding how to secure your environment in AWS. Know which parts of any given service are managed by AWS and which parts you are responsible for securing.

Understand how the IAM engine separates the authentication layer from the authorization process. Be familiar with the way that credentials are presented to AWS when an API is called.

Test Taking Tips

Time management is key for this exam. You only have 80 minutes – don’t waste them all on a question that has you stumped. Mark it for later review and move on. You will often be surprised that, when you come back to it later, the answer will be clear.

There is no penalty for wrong guesses. Make sure that you enter an answer for every question, even if you have no idea what the right answer might be. You won’t pass the exam if you guess every question, but it never hurts to try on the few that you might not know.

The AWS Certified SysOps Administrator – Associate exam is not designed to give you trick questions. If one answer seems obviously right, but another answer might be correct under special circumstances, go with the obvious answer. Dr. Theodore Woodward’s aphorism for his University of Maryland medical interns applies here: “If you hear hoof beats, think of horses not zebras.”

Multiple-choice questions require all answers to be correct; there is no partial credit for getting a portion correct. Pay extra attention to those questions when doing your review.

Plan on leaving time at the end of the exam for review. Even if you think you know an answer, you can mark it and return to it when you are done with the exam. Go through each one of those marked questions to make sure that you are still confident with those answers. Just be careful not to overthink your answer (remember “horses not zebras”).

Many questions have answer sets that are combinations of two pairs of answers. In AWS, everything is an API. In the next chapter, you will learn how to work with APIs and SDKs. So let’s start our engines and get on with the nitty gritty of working with AWS Services!
