SAP-C02 第 193 题
题目
A large education company recently introduced Amazon Workspaces to provide access to internal applications across multiple universities. The company is storing user profiles on an Amazon FSx for Windows File Server file system. The file system is configured with a DNS alias and is connected to a self-managed Active Directory. As more users begin to use the Workspaces, login time increases to unacceptable levels. An investigation reveals a degradation in performance of the file system. The company created the file system on HDD storage with a throughput of 16 MBps. A solutions architect must improve the performance of the file system during a defined maintenance window. What should the solutions architect do to meet these requirements with the LEAST administrative effort?

一家大型教育公司最近推出了 Amazon Workspaces，以提供对多所大学内部应用程序的访问。该公司将用户配置文件存储在 Amazon FSx for Windows File Server 文件系统上。文件系统配置有 DNS 别名并连接到自我管理的 Active Directory。随着越来越多的用户开始使用工作区，登录时间会增加到不可接受的水平。调查显示文件系统的性能下降。该公司在 HDD 存储上创建了吞吐量为 16 MBps 的文件系统。解决方案架构师必须在定义的维护时段内提高文件系统的性能。解决方案架构师应该如何做才能以最少的管理工作满足这些要求？
选项
A. Use AWS Backup to create a point-in-time backup of the file system. Restore the backup to a new FSx for Windows File Server file system. Select SSD as the storage type. Select 32 MBps as the throughput capacity. When the backup and restore process is completed, adjust the DNS alias accordingly. Delete the original file system.
中文翻译：
使用 AWS Backup 创建文件系统的时间点备份。将备份还原到新的 FSx for Windows File Server 文件系统。选择SSD作为存储类型。选择 32 MBps 作为吞吐量。备份和恢复过程完成后，相应地调整 DNS 别名。删除原来的文件系统。
B. Disconnect users from the file system. In the Amazon FSx console, update the throughput capacity to 32 MBps. Update the storage type to SSD. Reconnect users to the file system.
中文翻译：
断开用户与文件系统的连接。在 Amazon FSx 控制台中，将吞吐量更新为 32 MBps。将存储类型更新为SSD。将用户重新连接到文件系统。
C. Deploy an AWS DataSync agent onto a new Amazon EC2 instance. Create a task. Configure the existing file system as the source location. Configure a new FSx for Windows File Server file system with SSD storage and 32 MBps of throughput as the target location. Schedule the task. When the task is completed, adjust the DNS alias accordingly. Delete the original file system.
中文翻译：
将 AWS DataSync 代理部署到新的 Amazon EC2 实例上。创建任务。将现有文件系统配置为源位置。配置新的 FSx for Windows 文件服务器文件系统，将 SSD 存储和 32 MBps 的吞吐量作为目标位置。安排任务。任务完成后，相应地调整 DNS 别名。删除原来的文件系统。
D. Enable shadow copies on the existing file system by using a Windows PowerShell command. Schedule the shadow copy job to create a point-in-time backup of the file system. Choose to restore previous versions. Create a new FSx for Windows File Server file system with SSD storage and 32 MBps of throughput. When the copy job is completed, adjust the DNS alias. Delete the original file system.
中文翻译：
使用 Windows PowerShell 命令在现有文件系统上启用卷影副本。安排卷影复制作业以创建文件系统的时间点备份。选择恢复以前的版本。使用 SSD 存储和 32 MBps 的吞吐量创建新的 FSx for Windows 文件服务器文件系统。复制作业完成后，调整 DNS 别名。删除原来的文件系统。
答案
B
解析
正确答案：B 解析： 本题应选择 B。 正确选项： B. 断开用户与文件系统的连接。在 Amazon FSx 控制台中，将吞吐量更新为 32 MBps。将存储类型更新为SSD。将用户重新连接到文件系统。 选择理由： 该选项最直接地满足题干中的关键约束。做 SAP-C02 题目时，需要同时对照题干里的限定词，例如最高性能、最低运维开销、成本效益、可靠性、可扩展性、安全性、RTO/RPO、合规要求等。本题相关考点主要包括：EC2、FSx、C...
