Which option helps ensure LIF addresses are published after a failover in SVM DR?

• A. Set dynamic DNS updates on the SVM
• B. Enable LIF auto-rebind
• C. Change export policies
• D. Add FlexCache

Answer: (B)

When a failover happens in SVM DR, LIFs can move to a different data path, and their IPs must be made reachable on that new path. Enabling LIF auto-rebind allows the system to automatically rebind the LIF to an available port or node and publish its IP on the new path, keeping clients connected with no manual reconfiguration. This automatic rebinding ensures the LIF addresses are promptly published to the network after failover.

Dynamic DNS updates could reflect IP changes, but they aren’t immediate and rely on DNS propagation and TTLs, which can introduce delay. Export policies control access for NFS/SMB shares, not the publication of LIF IPs. FlexCache is a caching feature and doesn’t influence LIF reachability after failover.
