What command is used to update the storage account keys in an Azure ML workspace?

The command used to update the storage account keys in an Azure ML workspace is "az ml workspace sync-keys." This command is specifically designed to synchronize the keys of the storage account with the keys stored in the Azure Machine Learning workspace. By syncing the keys, you ensure that any changes to the storage account's keys are reflected in the workspace, which facilitates seamless access to the storage resources needed for data operations and model training.

The other commands do not perform the specific task of synchronizing keys. Some may imply broader operations like updating or changing settings in a workspace, but they lack the precise functionality needed for updating storage account keys, making them unsuitable for this scenario.
