Microsoft DevOps Engineer Expert AZ-400 Practice Question
You are preparing to onboard 50 Azure Storage accounts to Storage Insights so that capacity and transaction telemetry is sent to an existing Log Analytics workspace named LA-Prod. Development teams must not be required to turn on diagnostic settings for the storage accounts or restart any service. What is the minimum action you must perform on each storage account before you can successfully add it to Storage Insights?
Enable diagnostic settings on the storage account and route metrics to LA-Prod.
Enable the classic StorageMetrics counters on the storage account.
Install the Azure Monitor agent extension on the storage account.
Assign the Log Analytics workspace's managed identity the Storage Blob Data Reader role on the storage account.
Storage Insights does not rely on Azure Monitor diagnostic settings or the Azure Monitor agent. Instead, the Log Analytics workspace queries the storage resource directly. For the workspace to read service metadata, its managed identity needs Azure RBAC permission on the storage account. Granting the Storage Blob Data Reader role provides the necessary read-only access to blob containers and their data, which is sufficient for Storage Insights to gather capacity and transaction telemetry. Enabling classic metrics, installing agents, or configuring diagnostic settings is unnecessary for this scenario and would not satisfy the requirement to avoid additional configuration by development teams.
