Para calcular a classificação geral de estrelas e a análise percentual por estrela, não usamos uma média simples. Em vez disso, nosso sistema considera coisas como se uma avaliação é recente e se o avaliador comprou o item na Amazon. Ele também analisa avaliações para verificar a confiabilidade.
This book is a must have if you wish to take the exam. It guides you through the criteria of the exam step by step giving detailed explanations and helpful hints. What I really liked was that for each section the author demonstrated how to configure using the portal, powershell and the cli, which helped enormously. If you read this and perform the steps in a test environment you will have a very good chance of passing the exam!
Well it helped me pass the exam, but I really expected better from Microsoft. This book is littered with the sort of errors that a good editor/proof reader would have spotted. I did consult the errata for the book, and there was nothing in it!
