Which ONTAP feature can help identify active workloads that are consuming significant storage resources?

In NetApp ONTAP, performance statistics and monitoring tools (such as Active IQ Unified Manager, QoS statistics, and the ONTAP CLI statistics command) are specifically designed to help administrators identify active workloads consuming significant storage resources. These features track IOPS, throughput, and latency at various levels, including volumes, LUNs, and SVMs. By analyzing performance statistics, administrators can pinpoint "bully" workloads that are monopolizing disk or CPU resources and causing contention for other tenants. This visibility is essential for troubleshooting performance bottlenecks, implementing Quality of Service (QoS) policies, and ensuring equitable resource distribution across the cluster environment to maintain optimal storage health.

A. Disk sanitization is a security feature used to securely erase data from physical disks, completely unrelated to workload or performance monitoring.

B. S3 bucket versioning is an object storage feature for retaining multiple variants of an object, not for performance monitoring or workload identification.

D. NTP authentication secures time synchronization between the cluster and external time servers; it does not monitor or measure storage workloads.
