NetApp NS0-593 Exam - Topic 3 Question 83 Discussion

To enable DDNS updates to work, two actions should be performed:

Remove the NFS protocol from the cifs_01 data LIF.This is because DDNS updates are only supported for LIFs that have only one data protocol enabled1. The cifs_01 LIF has both NFS and CIFS protocols enabled, which prevents it from registering its DNS record dynamically. By removing the NFS protocol from the cifs_01 LIF, it will become eligible for DDNS updates.

Enable the -is-enabled parameter for the SVM DDNS services.This is because the -is-enabled parameter controls whether the SVM sends DDNS updates to the DNS servers2. The exhibit shows that the -is-enabled parameter is set to false for the svm1 SVM, which means that it does not send any DDNS updates. By enabling the -is-enabled parameter, the SVM will start sending DDNS updates for its eligible LIFs.Reference:
