Final answer:
In Azure Blob Storage, the container named container1 can be accessed using authorization methods such as Azure Active Directory, storage key, or shared access signature.
Step-by-step explanation:
When configuring access to a blob container in an Azure storage account, there are several authorization methods you can use. The options for authorization include Azure Active Directory (Azure AD), storage key, and shared access signature (SAS). Certificates are not used for authorization in Azure Blob Storage access. Thus, the correct authorization types that can be used for accessing container1 are Azure AD, storage key, or shared access signature only.
