SAP-C02 第 352 题
题目
A scientific company needs to process text and image data from an Amazon S3 bucket. The data is collected from several radar stations during a live, time-critical phase of a deep space mission. The radar stations upload the data to the source S3 bucket. The data is prefixed by radar station identification number. The company created a destination S3 bucket in a second account. Data must be copied from the source S3 bucket to the destination S3 bucket to meet a compliance objective. This replication occurs through the use of an S3 replication rule to cover all objects in the source S3 bucket. One specific radar station is identified as having the most accurate data. Data replication at this radar station must be monitored for completion within 30 minutes after the radar station uploads the objects to the source S3 bucket. What should a solutions architect do to meet these requirements?

一家科学公司需要处理来自 Amazon S3 存储桶的文本和图像数据。这些数据是在深空任务的实时、时间关键阶段从多个雷达站收集的。雷达站将数据上传到源S3存储桶。数据以雷达站识别号为前缀。该公司在第二个帐户中创建了目标 S3 存储桶。必须将数据从源 S3 存储桶复制到目标 S3 存储桶才能满足合规性目标。此复制通过使用 S3 复制规则来覆盖源 S3 存储桶中的所有对象来进行。一个特定的雷达站被认为拥有最准确的数据。必须监控该雷达站的数据复制是否在雷达站将对象上传到源 S3 存储桶后 30 分钟内完成。解决方案架构师应该怎样做才能满足这些要求？
选项
A. Setup an AWS DataSync agent to replicate the prefixed data from the source S3 bucket to the destination S3 bucket. Select to use all available bandwidth on the task, and monitor the task to ensure that itis in the TRANSFERRING status. Create an Amazon EventBridge rule to initiate an alert if this status changes.
中文翻译：
设置 AWS DataSync 代理以将带前缀的数据从源 S3 存储桶复制到目标 S3 存储桶。选择使用任务上的所有可用带宽，并监视任务以确保其处于 TRANSFERRING 状态。创建 Amazon EventBridge 规则，以便在此状态发生变化时启动警报。
B. In the second account, create another S3 bucket to receive data from the radar station with the most accurate data. Set up a new replication rule for this new S3 bucket to separate the replication from the other radar stations. Monitor the maximum replication time to the destination. Create an Amazon EventBridge rule to initiate an alert when the time exceeds the desired threshold.
中文翻译：
在第二个帐户中，创建另一个S3存储桶以接收来自数据最准确的雷达站的数据。为这个新的 S3 存储桶设置新的复制规则，以将复制与其他雷达站分开。监视到目标的最大复制时间。创建 Amazon EventBridge 规则以在时间超过所需阈值时启动警报。
C. Enable Amazon S3 Transfer Acceleration on the source S3 bucket, and configure the radar station with the most accurate data to use the new endpoint. Monitor the S3 destination bucket's TotalRequestLatency metric. Create an Amazon EventBridge rule to initiate an alert if this status changes.
中文翻译：
在源 S3 存储桶上启用 Amazon S3 传输加速，并使用最准确的数据配置雷达站以使用新终端节点。监控 S3 目标存储桶的 TotalRequestLatency 指标。创建 Amazon EventBridge 规则，以便在此状态发生变化时启动警报。
D. Create a new S3 replication rule on the source S3 bucket that filters for the keys that use the prefix of the radar station with the most accurate data. Enable S3 Replication Time Control (S3 RTC). Monitor the maximum replication time to the destination. Create an Amazon EventBridge rule to initiate an alert when the time exceeds the desired threshold.
中文翻译：
在源 S3 存储桶上创建新的 S3 复制规则，以筛选使用具有最准确数据的雷达站前缀的键。启用 S3 复制时间控制 (S3 RTC)。监视到目标的最大复制时间。创建 Amazon EventBridge 规则以在时间超过所需阈值时启动警报。
答案
D
解析
正确答案：D 解析： 本题应选择 D。 正确选项： D. 在源 S3 存储桶上创建新的 S3 复制规则，以筛选使用具有最准确数据的雷达站前缀的键。启用 S3 复制时间控制 (S3 RTC)。监视到目标的最大复制时间。创建 Amazon EventBridge 规则以在时间超过所需阈值时启动警报。 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、...
