SAP-C02 第 237 题

Route 53 Lambda S3 EC2 Kinesis Config

题目

A company has more than 10,000 sensors that send data to an on-premises Apache Kafka server by using the Message Queuing Telemetry Transport (MQTT) protocol. The on-premises Kafka server transforms the data and then stores the results as objects in an Amazon S3 bucket. Recently, the Kafka server crashed. The company lost sensor data while the server was being restored. A solutions architect must create a new design on AWS that is highly available and scalable to prevent a similar occurrence. Which solution will meet these requirements?

中文翻译:
一家公司拥有 10,000 多个传感器,这些传感器使用消息队列遥测传输 (MQTT) 协议将数据发送到本地 Apache Kafka 服务器。本地 Kafka 服务器转换数据,然后将结果作为对象存储在 Amazon S3 存储桶中。最近,Kafka服务器崩溃了。该公司在恢复服务器时丢失了传感器数据。解决方案架构师必须在 AWS 上创建高度可用且可扩展的新设计,以防止类似情况发生。哪种解决方案可以满足这些要求?

选项

A. Launch two Amazon EC2 instances to host the Kafka server in an active/standby configuration across two Availability Zones. Create a domain name in Amazon Route 53. Create a Route 53 failover policy. Route the sensors to send the data to the domain name.

中文翻译:
启动两个 Amazon EC2 实例以跨两个可用区以主动/备用配置托管 Kafka 服务器。在 Amazon Route 53 中创建域名。创建 Route 53 故障转移策略。路由传感器以将数据发送到域名。

B. Migrate the on-premises Kafka server to Amazon Managed Streaming for Apache Kafka (Amazon MSK). Create a Network Load Balancer (NLB) that points to the Amazon MSK broker. Enable NLB health checks. Route the sensors to send the data to the NLB.

中文翻译:
将本地 Kafka 服务器迁移到 Amazon Managed Streaming for Apache Kafka (Amazon MSK)。创建指向 Amazon MSK 代理的网络负载均衡器 (NLB)。启用 NLB 运行状况检查。路由传感器以将数据发送到 NLB。

C. Deploy AWS IoT Core, and connect it to an Amazon Kinesis Data Firehose delivery stream. Use an AWS Lambda function to handle data transformation. Route the sensors to send the data to AWS IoT Core.

中文翻译:
部署 AWS IoT Core,并将其连接到 Amazon Kinesis Data Firehose 传输流。使用 AWS Lambda 函数处理数据转换。路由传感器以将数据发送到 AWS IoT Core。

D. Deploy AWS IoT Core, and launch an Amazon EC2 instance to host the Kafka server. Configure AWS IoT Core to send the data to the EC2 instance. Route the sensors to send the data to AWS IoT Core.

中文翻译:
部署 AWS IoT Core,并启动 Amazon EC2 实例来托管 Kafka 服务器。配置 AWS IoT Core 以将数据发送到 EC2 实例。路由传感器以将数据发送到 AWS IoT Core。

答案

C

解析

正确答案:C 解析: 本题应选择 C。 正确选项: C. 部署 AWS IoT Core,并将其连接到 Amazon Kinesis Data Firehose 传输流。使用 AWS Lambda 函数处理数据转换。路由传感器以将数据发送到 AWS IoT Core。 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、R...
