Which three data analysis tasks should you perform?

A company maintains an Azure storage account. The storage account uses blobs and tables.
Customers access the storage account by using shared access signatures (SASs).
You need to monitor the usage of the storage services. You need to do the following:
Understand which storage areas perform operations that incur an Azure fee.
Understand which requests are denied because of insufficient permissions.
Validate that the performance of the storage account meets the service level agreement (SLA) for the Azure
Storage service.
Which three data analysis tasks should you perform? Each correct answer presents part of the solution.

A.
Use data from the logs of the storage services to find individual storage access attempts that do not comply
with the SLA.

B.
Use data from the logs of the storage services to calculate aggregate server latency across individual
requests. Determine whether the results of this calculation indicate that the Azure Storage service is in
compliance with the SLA.

C.
Analyze the logs of the storage services to determine which storage services were inaccessible because of
permissions issues.

D.
Review the Azure documentation to determine which storage operations are billable. Then find records of
those operations in the logs of the storage services.

E.
Analyze the logs of the storage services to find records of operations that are marked as billable.

F.
Correlate the data logged from the storage service with the permissions to store data in the individual blobs
and containers. Determine which storage services were inaccessible because of permissions issues.
