一个网络接口 (NIC) :在指定的虚拟网络/子网中保留专用 IP 地址的网络接口。 此网络接口是部署虚拟机 (VM) 时部署的同一个资源,但它不会分配到 VM,而是由专用终结点拥有。
专用域名系统 DNS 区域:如果你以前没有为此虚拟网络部署过专用终结点,系统将为虚拟网络部署新的专用 DNS 区域。 此外,将为此 DNS 区域中的存储帐户创建 DNS A 记录。 如果已在此虚拟网络中部署了专用终结点,则会将存储帐户的新 A 记录添加到现有 DNS 区域。 部署 DNS 区域是可选操作。 不过,强烈建议执行此操作;如果使用 AD 服务主体或 FileREST API 装载 Azure 文件共享,则必须执行此操作。

创建 Azure 专用 DNS 区域可将存储帐户的原始名称(例如 storageaccount.file.core.chinacloudapi.cn)解析为虚拟网络内部的专用 IP。 尽管从创建专用终结点的角度来看,此操作是可选的,但如果直接使用 AD 用户主体装载或通过 REST API 访问 Azure 文件共享,则此操作肯定是必需的。
