     - Feature gate name: PreferNominatedNode
     - Components depending on the feature gate: kube-scheduler
 
+* **Does enabling the feature change any default behavior?**
+  Yes. The pod with the nominated node set will be evaluated first in any scheduling cycle,
+  this is only the default process logic that is handled by scheduler, end-user will not
+  and need not aware of any difference.
+
+* **Can the feature be disabled once it has been enabled (i.e. can we roll back
+  the enablement)?**
+  Yes. This could be opt-out by the feature gate, once switch off, it will fall back
+  to original behavior.
+
+* **What happens if we reenable the feature if it was previously rolled back?**
+  Nothing needs to be aware of for the end-user.
+
 * **Are there any tests for feature enablement/disablement?**
   unittest will cover this.
