Which statement best describes the network pattern recommended for ONTAP deployments to improve performance and isolation?

• A. Using a single data network for all traffic.
• B. Keep data networks, cluster interconnects, and management networks separated for performance and security.
• C. Separating workloads with separate SVMs isolates workloads and simplifies management.
• D. SVMs are deprecated in ONTAP.

Answer: (C)

In ONTAP, Storage Virtual Machines (SVMs) create separate, self-contained data access environments. Using separate SVMs for different workloads isolates the workloads at the data access layer, so one workload’s traffic, protocols, security policies, quotas, and administration don’t interfere with or expose others. This separation also makes management easier because each workload can have its own administrators, policies, and network configuration tailored to its needs. Separating workloads with separate SVMs provides both better performance and stronger isolation: you can apply per-SVM QoS and resource controls, tune networking and protocol options for each workload, and prevent cross-workload contention. It also offers clear administrative boundaries, reducing the risk that changes in one workload affect others. The other options don’t fit as directly. Using a single data network risks contention across all traffic. Keeping data, interconnect, and management networks separated is a good practice, but it describes network segmentation rather than isolating workloads at the data access layer. And SVMs are not deprecated in ONTAP.
