Possible roles for Single-Node Cluster: (choose three)
The correct answer is B. Development C. Testing D. ABM. Single-Node Clusters in NetApp lack HA failover, making them unsuitable for production but valid for development, testing, and ABM (Automated Blade Management or non-critical) use cases.

Why each option
Single-Node Clusters in NetApp lack HA failover, making them unsuitable for production but valid for development, testing, and ABM (Automated Blade Management or non-critical) use cases.
Production workloads require high availability failover to prevent data unavailability during node failures, which a Single-Node Cluster cannot provide.
Development environments can tolerate downtime and do not require the redundancy that production workloads demand, making a Single-Node Cluster acceptable.
Testing environments similarly do not require continuous availability, so the absence of HA failover in a Single-Node Cluster is acceptable.
ABM (non-production) workloads have lower availability requirements and are suitable for Single-Node Cluster deployments where cost and simplicity are prioritized.
Concept tested: Single-Node Cluster appropriate use cases
