NetApp Certified Data Administrator (NCDA) – ONTAP v4 — Question 10

Which network construct is required to enable nondisruptive failover between nodes in a Multi-AZ NetApp Cloud Volumes ONTAP cluster in AWS?

Answer options

• A. floating IPs
• B. security groups
• C. elastic network interfaces
• D. Intercluster LIFs

Correct answer: C

Explanation

The correct answer is C, elastic network interfaces, as they facilitate communication between nodes and ensure that failover processes can occur without disruption. Options A, B, and D do not provide the necessary functionality for nondisruptive failover; floating IPs are used for redundancy, security groups manage access control, and Intercluster LIFs are specific to intercluster communication rather than failover within a single cluster.
