Final answer:
The free Azure account credits must be used within 30 days. It's important for new users to utilize these credits during this trial period to explore Azure's cloud services.
Step-by-step explanation:
The credits provided as part of a free Azure account must be used within 30 days. Azure offers new users a free account with a limited amount of credit to experiment with their cloud services. After signing up for a free account, it is crucial that the user takes advantage of the provided resources within this time frame, as the credits will expire thereafter. This trial period allows users to explore the capabilities of Azure services without having to make an initial financial commitment.
