You have a general-purpose v1 storage account (storage1) using locally-redundant storage (LRS). You must ensure data is protected if an availability zone fails, while minimizing cost and management effort. What should you do first?

Upgrading the account to general-purpose v2 is the correct first step because general-purpose v1 storage accounts do not support zone-redundant storage (ZRS) or geo-zone-redundant storage (GZRS), which are necessary for data protection across availability zones. General-purpose v2 accounts offer these redundancy options and are also more cost-effective and feature-rich. Creating a new storage account would work but is not the most efficient first step, as it requires migrating all data, which is more complex and time-consuming than an in-place upgrade. Configuring object replication rules is for replicating data between different storage accounts or within the same account for specific scenarios, not for changing the underlying redundancy type of the account itself. Modifying the Replication setting of storage1 is not possible for general-purpose v1 accounts to achieve zone-level redundancy; the option simply isn't available.
