Final answer:
The question addresses whether cluster dialect fencing allows for cluster rolling upgrades in Scale-Out File Servers, and the answer is true. It enables the server cluster to maintain functionality during upgrades of individual nodes.
Step-by-step explanation:
The question asks whether cluster dialect fencing supports cluster rolling upgrades for the Scale-Out File Servers feature. The answer to this question is true. Cluster dialect fencing is a feature that allows for the isolation of nodes that are not running the same version of the Server Message Block (SMB) protocol.
This is essential for cluster rolling upgrades, which enable you to upgrade the operating system of cluster nodes without stopping the Scale-Out File Server. This means that during an upgrade, a server cluster can maintain full functionality while individual nodes are being updated one at a time.
