エンジニアは 3 つのノードを持つ Cisco DNA Center クラスタを作成しますが、すべてのサービスは 1 つのホスト ノードで実行されます。この問題を解決するにはどのアクションを実行すればよいでしょうか?
正解:C
To deploy Cisco DNA Center on a three-node cluster with High Availability (HA) enabled, complete the following procedure: Step 1: Configure Cisco DNA Center on the first node in your cluster... Step 2: Configure Cisco DNA Center on the second node in your cluster... Step 3: Configure Cisco DNA Center on the third node in your cluster... Step 4: Enable high availability on your cluster: a. In the Cisco DNA Center GUI, click and choose System Settings. The System 360 tab is displayed by default. b. In the Hosts area, click Enable Service Distribution. After you click Enable Service Distribution, Cisco DNA Center enters into maintenance mode. In this mode, Cisco DNA Center is unavailable until the redistribution of services is completed. You should take this into account when scheduling an HA deployment.
