SAP-C02 第 175 题
题目
A company has an application that runs as a ReplicaSet of multiple pods in an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. The EKS cluster has nodes in multiple Availability Zones. The application generates many small files that must be accessible across all running instances of the application. The company needs to back up the files and retain the backups for 1 year. Which solution will meet these requirements while providing the FASTEST storage performance?
中文翻译:
一家公司有一个应用程序,该应用程序在 Amazon Elastic Kubernetes Service (Amazon EKS) 集群中作为多个 Pod 的 ReplicaSet 运行。 EKS 集群在多个可用区中拥有节点。该应用程序会生成许多小文件,这些文件必须可以在该应用程序的所有正在运行的实例中访问。公司需要对文件进行备份,并保留备份1年。哪种解决方案能够满足这些要求,同时提供最快的存储性能?
选项
A. Create an Amazon Elastic File System (Amazon EFS) file system and a mount target for each subnet that contains nodes in the EKS cluster. Configure the ReplicaSet to mount the file system. Direct the application to store files in the file system. Configure AWS Backup to back up and retain copies of the data for 1 year.
中文翻译:
为包含 EKS 集群中的节点的每个子网创建 Amazon Elastic File System (Amazon EFS) 文件系统和挂载目标。配置ReplicaSet挂载文件系统。指示应用程序将文件存储在文件系统中。配置 AWS Backup 以备份数据副本并保留 1 年。
B. Create an Amazon Elastic Block Store (Amazon EBS) volume. Enable the EBS Multi-Attach feature. Configure the ReplicaSet to mount the EBS volume. Direct the application to store files in the EBS volume. Configure AWS Backup to back up and retain copies of the data for 1 year.
中文翻译:
创建 Amazon Elastic Block Store (Amazon EBS) 卷。启用 EBS 多重附加功能。配置 ReplicaSet 以挂载 EBS 卷。指示应用程序将文件存储在 EBS 卷中。配置 AWS Backup 以备份数据副本并保留 1 年。
C. Create an Amazon S3 bucket. Configure the ReplicaSet to mount the S3 bucket. Direct the application to store files in the S3 bucket. Configure S3 Versioning to retain copies of the data. Configure an S3 Lifecycle policy to delete objects after 1 year.
中文翻译:
创建 Amazon S3 存储桶。配置 ReplicaSet 以挂载 S3 存储桶。指示应用程序将文件存储在 S3 存储桶中。配置 S3 版本控制以保留数据副本。配置 S3 生命周期策略以在 1 年后删除对象。
D. Configure the ReplicaSet to use the storage available on each of the running application pods to store the files locally. Use a third-party tool to back up the EKS cluster for 1 year.
中文翻译:
将 ReplicaSet 配置为使用每个正在运行的应用程序 Pod 上可用的存储来在本地存储文件。使用第三方工具备份EKS集群1年。
答案
A
解析
