دانلود کتاب گواهینامه حرفه ای شبکه AWS – راهنمای آزمون تخصصی

Before we begin, let me thank you for choosing this book as your guide to the AWS Certified Advanced Networking – Specialty exam. The intention of this book is to provide you with a tool that will help you to gauge your AWS and general networking knowledge in order to determine your confidence level for passing the AWS Certified Advanced Networking – Specialty exam. The goal of the book is to focus exclusively on the networking components of AWS. We will be discussing the networking services and their features in great detail and a lot of depth. This does, however, come with a caveat—I will be assuming the reader has previous experience of working as a networking engineer and is familiar with AWS services and concepts. This assumption will come at the expense of explaining basic networking concepts such as how the OSI model works, how the IP protocol operates, how we calculate IP addresses, and so on. Furthermore, the assumption implies that the reader is familiar with AWS and the services AWS provides to run applications. The assumption will mean that some AWS services mentioned in this book will need to be read up on outside of the context of this book. If you cannot determine how comfortable you are with AWS services, I recommend picking up a copy of AWS Certified SysOps Administrator – Associate Guide or the AWS Certified Solutions Architect – Associate Guide, both available from Packt Publishing, because both of these books are great tools to get you started with AWS. If you are a system administrator or a network engineer interested in getting certified with an advanced cloud networking certification, then this book is for you. Prior experience of cloud administration and networking is necessary.
