Step-by-step explanation:
With an Azure free account, after 30 days, certain products may still be free depending on the specific terms and conditions of the account. The Azure free account provides limited access to a range of Azure products for the first 30 days, including popular services like Virtual Machines, Blob Storage, and SQL Database. However, after the initial 30-day period, some services may require payment or transition to a paid tier, while others may remain free within the limits of the account's usage quotas.
