Which ONTAP feature isolates IP addresses and data traffic for an SVM?

• A. IPspace caches IP addresses for faster access.
• B. LIF performs data routing between tenants.
• C. IPspace isolates IP addresses and data traffic for an SVM.
• D. A FlexVol is used to store IP configurations.

Answer: (C)

Isolating IP addresses and data traffic for an SVM is accomplished by using IPspace. IPspace creates separate IP network namespaces inside an SVM, so the IP addresses, routing, and traffic associated with one IPspace stay isolated from others. This means you can assign a distinct set of IPs to each SVM and have its own routing, ARP/ND, and LIFs that operate only within that IPspace, providing true tenant isolation for both control and data planes.

LIFs are individual network interfaces used to access data, and they exist within an IPspace, but they don’t by themselves provide isolation across tenants. A FlexVol is simply a storage container for data, not related to IP address or traffic isolation. The option suggesting IPspace caches IP addresses isn’t a real ONTAP feature.
