A customer wants critical applications to achieve consistent and guaranteed performance. Which NetApp ONTAP feature accomplishes this goal?

Explanation:
Quality of Service (QoS) is the feature that provides predictable, guaranteed performance for critical applications. By creating QoS policies and applying them to specific volumes or LUNs, you can set resource limits and reservations (minimum and/or maximum IOPS and bandwidth). This ensures those workloads get the needed I/O access and protects them from being throttled by other tenants or less important apps, delivering consistent latency and throughput. Other options improve performance in different ways—Flash Cache speeds hot data, FlexCache caches remote data, and Flash Pool combines SSDs with HDDs for better overall performance. None of these guarantees service levels the way QoS does, which is why QoS is the correct choice for guaranteed performance.
