What are two ways a storage administrator can improve the operational availability of NAS application data? (Choose two.)
The correct answer is C. By providing multiple data logical interfaces D. By utilizing the volume move feature. Operational availability for NAS data means clients can continuously access data even during disruptions. (C) Providing multiple data LIFs (Logical Interfaces) enables clients to reconnect on an alternate LIF if one becomes unavailable due to network or node failure, reducing…

Explanation
Operational availability for NAS data means clients can continuously access data even during disruptions. (C) Providing multiple data LIFs (Logical Interfaces) enables clients to reconnect on an alternate LIF if one becomes unavailable due to network or node failure, reducing downtime and improving path redundancy. (D) The volume move feature in clustered Data ONTAP allows non-disruptive migration of volumes between nodes in the same cluster while clients remain connected, enabling maintenance without application interruption. Option A (USB disk backup) addresses data protection/recovery, not operational availability. Option B (ALUA - Asymmetric Logical Unit Access) applies to SAN/block storage protocols, not NAS.
