Which three storage features can be scaled by storage administrators? (Choose three.)

Capacity scaling is a foundational feature of NetApp clustered ONTAP, allowing administrators to non-disruptively add more storage systems and larger disks to an existing cluster. This lets storage grow incrementally without downtime or data migration.

Energy or power scaling is not a recognized storage scaling category, and clusters do not share a single power source as a designed scaling mechanism.

E-Series and FAS-Series systems run fundamentally different operating systems (SANtricity vs. ONTAP) and cannot be joined into a single clustered ONTAP cluster.

Adding more network switches is an infrastructure design decision, not a named storage-scaling feature that administrators configure as part of a scaling strategy.

Operational scaling allows the entire cluster - regardless of how many nodes it contains - to be administered through a single, resilient management interface. This single pane of glass keeps operational complexity flat as the cluster expands.

Performance scaling is achieved by combining Flash Cache (Performance Acceleration Module cards), SSDs for Flash Pool auto-tiering, and Quality of Service policies to tune IOPS and throughput. These mechanisms allow performance to be increased independently of capacity.
