ハードウェア障害により、ユーザーは主要な VM にアクセスできなくなりました。プロキシ サーバーは、データを保護するために VM の PIT スナップショットを定期的に取得します。 これはどのような種類のデータ保護方法と呼ばれますか?
正解:D
Explanation This is an example of an image-based data protection method. With image-based data protection, a proxy server regularly takes Point-in-Time (PIT) snapshots of the virtual machine (VM) that is being protected. These snapshots are then stored in a secure location, allowing the user to quickly restore access to the VM in the event of a hardware failure. This type of data protection is effective for preserving the state of the VM, as well as any data stored on it, making it a reliable and secure way to protect data.
