Final answer:
The statement is false; Azure storage accounts use Locally Redundant Storage (LRS) by default, which replicates data three times within the same data center in the primary region.
Step-by-step explanation:
The statement that data uploaded to an Azure storage account is only copied once within a single physical location in the primary region is false. By default, Azure storage accounts are configured to use Locally Redundant Storage (LRS), which replicates data three times within the same data center in the primary region. This ensures that your storage account data is protected against server rack or drive failures. However, there are also options to increase redundancy and resilience, such as Zone Redundant Storage (ZRS), Geo-Redundant Storage (GRS), and Read-Access Geo-Redundant Storage (RA-GRS), which provide additional data replication across different locations.
