Difficulty: HardAzure Backup Reports and Monitoring

An administrator configures diagnostic settings on a Recovery Services vault named Vault1 to enable Azure Backup Reports. The administrator targets a central Log Analytics workspace named Workspace1. To comply with corporate security and performance policies, the diagnostic setting is configured to use the Resource-specific schema. The administrator only selects the CoreAzureBackup log category. A week later, the administrator runs a Kusto Query Language (KQL) query targeting the AddonAzureBackupJobs table to analyze backup job execution times and status history, but the query returns no results. What should the administrator do to resolve this issue?

  1. Modify the diagnostic settings of Vault1 to select the AddonAzureBackupJobs log category.Answer
  2. B
    Modify the diagnostic settings of Vault1 to use the AzureDiagnostics table schema.
  3. C
    Modify the KQL query to retrieve job details from the CoreAzureBackup table.
  4. D
    Configure diagnostic settings on the individual virtual machines to send Guest OS diagnostic logs to Workspace1.

Answer

Modify the diagnostic settings of the Recovery Services vault to select the AddonAzureBackupJobs log category.
The correct action is to modify the diagnostic settings to select the AddonAzureBackupJobs log category. In Resource-specific schema mode, Azure Backup routes diagnostics logs to specific dedicated tables. The AddonAzureBackupJobs table is only populated when the corresponding AddonAzureBackupJobs log category is selected in the diagnostic settings of the Recovery Services vault.

Step-by-Step Solution

1
Identify the data needed for the query
The query requires job execution times and status history, which are part of the backup job diagnostic data.
Understanding what logs contain the required information is necessary to locate the root cause.
2
Analyze the current diagnostic settings configuration
Only the CoreAzureBackup log category is selected, and the destination schema is set to Resource-specific.
This configuration sends vault and policy metadata (to the CoreAzureBackup table) but does not enable the collection of job logs.
3
Determine the required log category for Resource-specific schema
In Resource-specific schema, job logs are sent to the AddonAzureBackupJobs table, which requires enabling the AddonAzureBackupJobs log category in the vault's diagnostic settings.
Enabling the correct log category ensures that the Azure Backup service routes the required data to the Log Analytics workspace.
