    Hi elnook,

    Thanks for bringing up the question.

    An Availability Set is a logical grouping of Azure virtual machines (VMs) that are deployed across different fault domains and update domains within a single Azure region. This helps to protect your VMs from unplanned outages such as hardware failures or software updates.

    The correct answer is: Create an Availability Set that has three update domains and two fault domains. Because the VMs will be spread across three update domains and two fault domains. This means that if one update domain or fault domain goes down, the other two will still be available. This will ensure that at least two VMs are always available during planned Azure maintenance.

    The incorrect option is: Create an Availability Set that has two update domains and three fault domains. Because this would only guarantee that one VM is available during planned maintenance.

    Take note that during scheduled maintenance, only one update domain is updated at any given time. A rebooted update domain is given 30 minutes to recover before maintenance is initiated on a different update domain.
