Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

The credits provided as part of a free Azure account must be used within 30 days. This timeframe is set to encourage new users to explore and utilize Azure services actively, allowing them to experience the platform's features and capabilities without incurring costs.

The 30-day limit applies specifically to the initial set of credits offered to new users when they first create an Azure free account. After this period, any unused credits expire, enforcing a sense of urgency to test and engage with the resources available on Azure.

The other timeframes listed do not align with Azure's policy for free credits. Users are encouraged to take advantages of the features and services within this limited window to fully leverage their initial experience with the Azure platform.
