AWS Certified Cloud Practitioner (CLF-C01) Practice Questions IMPORTANT NOTE: This document covers the AWS Certified Cloud Practitioner exam (CLF-C01), however there is a new version of the exam out now (CLF-C02). I think these questions will still remain useful even for CLF-C02, tho it’s worth checking out other resources for CLF-C02 too, just to ensure you cover all the bases. Good luck in the exam – Cathal :) 15 July 2024 IMPORTANT NOTE #2: Please can I ask that people stop sending me emails requesting access to this document, the document is clearly already available online for all. I receive many messages every week regarding this. Practice Questions Intro I have included questions mainly taken from this website but also from other sources (such as this website). The answers on the above websites were often incorrect and the discussion sections contained confusing and conflicting information, so I think it is a good idea to compile the correct answers, along with reasoning of why they are the correct answers. I think a good way of revising for any exam is going over past paper questions, for me when I studied for this exam, I’d do 50 questions a day and it eventually stuck after a few weeks. I think I have gotten the correct answers for all the questions, though if you notice any errors or otherwise have any ideas for improvements just let me know at [email protected] I have also removed most of the duplicate questions I could find, there are definitely some duplicates remaining though but I do not have enough time to search for them all. In some cases I’ve left some very similar though not identical questions in place, they may be a bit redundant but I think it is worth getting very familiar with the topics they cover e.g. shared responsibility model, basics of cloud computing and best practices. I’ve included quoted text often in answers, these are normally directly from some AWS literature but not always, sometimes they are from external sources. I have double-checked any non-AWS sources to ensure they are reliable however. Occasionally I may update this document with the most recent information so if you do save your own copy of the document be sure to download a new copy every once in a while. I have also created a guide for the AWS Cloud Practitioner exam, it can be accessed here Click on the comment icon beside the question to see the answers and explanations: Example comment icon → Commented [MC1]: Answers that are correct will be shown in a green outline like this Thanks, Answers that are incorrect will be shown in a red outline Cathal like this Further information will be shown in a blue outline like this 1-50 Commented [MC2]: C “Data configuration (i.e. encrypting data at rest and in 1.
