5 mini articles for the Microsoft AZ-900 exam preparation

I have 5 Microsoft AZ-900 exam practice questions with answers. I need someone to write 300-500 word explanation on each question giving more details about the topic of the question so that students would know how to answer similar question in the future. ---------------------------------------------------------------------------------- Example question (I would provide it to you): You have been informed by your superiors of the company's intentions to automate server deployment to Azure. There is, however, some concern that administrative credentials could be uncovered during this process. You are required to make sure that during the deployment, the administrative credentials are encrypted using a suitable Azure solution. Solution: You recommend the use of Azure Multi-Factor Authentication (MFA). Does the solution meet the goal? A. Yes B. No Correct answer: No ----------------------------------------------------------------------------------- Example article (you would have to write it): 300-500 word article explaining what MFA is and why it is not a correct answer. Explain what technologies could be used to automate server deployment to Azure and how to secure administrative credentials using Azure keyvault. Explain that the correct answer in this situation would be Azure Key Vault.
