课程名称：AWS认证解决方案架构师助理 SAA-C02考试 课程概述：本课程旨在帮助学员准备AWS认证解决方案架构师助理（SAA-C02）考试。课程内容涵盖了使用AWS设计和部署可靠的应用程序的最佳实践与技巧。通过实际示例和样题，学员将能够深入理解AWS服务并掌握解决方案架构的关键概念。 样题： 1. **网站故障备援**：设计一个解决方案，如果主要网站不可用，则用户会被引导到备份静态错误页面。学员需选择合理的Amazon Route 53配置，以最小化更改和基础设施负担。 2. **高性能计算工作负载**：针对频繁通信且需要低延迟和高吞吐量的Amazon EC2配置进行设计。学员需考虑不同的放置组选择，确保满足性能需求。 3. **可扩展的Web应用**：企业希望在AWS上托管一个可扩展的Web应用，用户来自全球不同地区。为了降低上传和下载延迟、提升性能，学员需选择最佳的AWS服务组合。 4. **文件服务器迁移**：企业从本地基础设施迁移至AWS，并需要替换利用分布式文件系统复制(DFSR)的数据存储。学员需选择适合的AWS存储服务。 5. **微服务集成**：将一个混合处理的传统应用重写为两个可以独立扩展的微服务，学员需选择最合适的集成方式以优化数据传输。 6. **实时数据处理**：公司希望从批处理转向近实时数据处理，学员需选择最具成本效益的AWS服务组合，以实现流数据的处理，满足实时洞察需求。 本课程通过丰富的案例和样题，帮助学员掌握AWS认证所需的核心技能与知识，助力学生顺利通过考试。
Sample Questions:Q) A solutions architect is designing a solution where users will be directed to a backup static error page if the primary website is unavailable. The primary website's DNS records are hosted in Amazon Route 53 where their domain is pointing toan Application Load Balancer (ALB).Which configuration should the solutions architect use to meet the company's needs while minimizing changes and infrastructure overhead?A. Point a Route 53 alias record to an Amazon Cloud Front distribution with the ALB as one of its origins. Then, create custom error pages for the distribution.B. Set up a Route 53 active-passive failover configuration. Direct traffic to a static error page hosted within an Amazon S3 bucket when Route 53 health checks determine that the ALB endpoint is unhealthy.C. Update the Route 53 record to use a latency-based routing policy. Add the backup static error page hosted within an Amazon S3 bucket to the record so the traffic is sent to the most responsive endpoints.D. Set up a Route 53 active-active configuration with the ALB and an Amazon EC2 instance hosting a static error page as endpoints. Route 53 will only send requests to the instance if the heal checks fail for the ALB.Q) A solutions architect is designing a high performance computing (HPC) workload on Amazon EC2. The EC2 instances need to communicate to each other frequently and require network performance with low latency and high throughput.Which EC2 configuration meets these requirements?A. Launch the EC2 instances in a cluster placement group in one Availability Zone.B. Launch the EC2 instances in a spread placement group in one Availability Zone.C. Launch the EC2 instances in an Auto Scaling group in two Regions and peer the VPCs.D. Launch the EC2 instances in an Auto Scaling group spanning multiple Availability Zones.Q) A company wants to host a scalable web application on AWS. The application will be accessed by users from different geographic regions of the world. Application users will be able to download and upload unique data up to gigabytes in size. The development team wants a cost-effective solution to minimize upload and download latency and maximize performance. What should a solutions architect do to accomplish this?A. Use Amazon S3 with Transfer Acceleration to host the application.B. Use Amazon S3 with Cache Control headers to host the application.C. Use Amazon EC2 with Auto Scaling and Amazon Cloud Front to host the application.D. Use Amazon EC2 with Auto Scaling and Amazon Elasti Cache to host the application.Q) A company is migrating from an on-premises infrastructure to the AWS Cloud. One of the company's applications stores files on a Windows file server farm that uses Distributed File System Replication (DFSR) to keep data in sync. A solutions architect needs to replace the file server farm. Which service should the solutions architect use?A. Amazon EFSB. Amazon FSxC. Amazon S3D. AWS Storage GatewayQ) A company has a legacy application that process data in two parts. The second part of the process takes longer than the first, so the company has decided to rewrite the application as two microservices running on Amazon ECS that can scale independently. How should a solutions architect integrate the microservices?A. Implement code in microservice 1 to send data to an Amazon S3 bucket. Use S3 event notifications to invoke microservice 2.B. Implement code in microservice 1 to publish data to an Amazon SNS topic. Implement code in microservice 2 to subscribe to this topic.C. Implement code in microservice 1 to send data to Amazon Kinesis Data Firehose. Implement code in microservice 2 to read from Kinesis Data Firehose.D. Implement code in microservice 1 to send data to an Amazon SQS queue. Implement code in microservice 2 to process messages from the queue.Q) A company captures clickstream data from multiple websites and analyzes it using batch processing. The data is loaded nightly into Amazon Redshift and is consumed by business analysts. The company wants to move towards near-realtime data processing for timely insights. The solution should process the streaming data with minimal effort and operational overhead.Which combination of AWS services are MOST cost-effective for this solution? (Choose two.)A. Amazon EC2B. AWS LambdaC. Amazon Kinesis Data StreamsD. Amazon Kinesis Data FirehoseE. Amazon Kinesis Data Analytics
