システム管理者は、VM を使用して、多数のアプリケーション VM を含む新しいソリューションを展開しています。 ハイパーバイザーに障害が発生した場合にアプリケーション環境に高可用性を提供するのは、次のうちどれですか?
正解:A
Explanation Anti-affinity rules are rules or policies that prevent two or more VMs from running on the same host or cluster in a cloud environment. Anti-affinity rules can provide high availability to an application environment in case of hypervisor failure, as they can distribute or separate the application VMs across different hosts or clusters and avoid having a single point of failure. Anti-affinity rules can also improve performance and reliability, as they can reduce contention and load by balancing the resource utilization across multiple hosts or clusters.
