You have an Azure subscription with a VM named VM1 (Windows Server). The subscription contains several storage accounts (storage1–storage4). You plan to enable boot diagnostics for VM1. Which storage account should you specify for storing the boot diagnostics logs and screenshots?

When enabling boot diagnostics for an Azure VM, the storage account specified must be in the same region as the virtual machine. If the storage account is in a different region, the boot diagnostics feature will fail to capture logs and screenshots. Therefore, if VM1 is located in the same region as storage1, then storage1 is the correct choice. Without information on the regions of storage2, storage3, and storage4, they cannot be definitively chosen, but the primary constraint for boot diagnostics is regional co-location.
