Which capability of a LIF supports high availability in ONTAP?

• A. It encrypts data at rest.
• B. It can be moved or failed over to another node.
• C. It automatically scales CPU.
• D. It stores volume metadata.

Answer: (B)

LIFs are designed to keep storage accessible even if part of the system has a failure. The way they do this is by being able to move to a partner node or fail over to it, while keeping the same IP address that clients connect to. When a node in the cluster goes down or becomes unavailable, the LIF is brought online on the surviving node, so client connections don’t drop and data stays accessible. That capability—the ability to be moved or fail over to another node—directly supports high availability. Encryption at rest, automatic CPU scaling, and storing volume metadata protect different aspects (security, performance scaling, and metadata management) but don’t provide HA for client connections in the same way.
