**Coursera 课程总结：Istio 认证助理 (ICA) 备考练习** 本 Coursera 课程旨在为 Linux Foundation 的 Istio 认证助理 (ICA) 考试提供练习，帮助学习者熟悉真实的考试题目和场景。 **重要提示：** * **实际 ICA 考试为限时、侧重实践（实验/操作）的考试。** 本课程提供的练习题仅为帮助学习者熟悉真实考试的题型。 * **本课程不提供实际的实验环境。** 由于当前平台不支持实验，课程内容侧重于提供与真实考试相关的题目和详细解释。 * **为获得真实考试的答案指导，建议在提交练习后查看解决方案。** * **推荐练习环境：** 学习者可以利用自己的 Kubernetes 集群，并使用 Istio 安装自带的 BookInfo 应用进行类似的实验练习。 * **如需从零开始的 Istio 结构化培训，欢迎通过 LinkedIn 联系讲师。** 讲师团队会及时更新下一期培训班的信息。 **Istio 认证助理 (ICA) 考试概述：** * **目标：** 证明学习者在设置 Istio 方面对 Istio 原理、术语和最佳实践有扎实的理解。 * **目标人群：** 工程师、CI/CD 从业者或对 Istio 感兴趣的任何人。 * **能力证明：** * 理解 GitOps 模式，包括何时何地使用它们。 * 了解在清单格式、打包、状态存储系统和协调引擎等工具方面需要注意的事项，以遵循和扩展 GitOps 原则。 **考试重点领域和能力：** 1. **Istio 安装、升级和配置 (7%)** * 使用 Istio CLI 安装基础集群。 * 通过 IstioOperator API 自定义 Istio 安装。 * 使用 overlays 管理 Istio 组件设置。 2. **流量管理 (40%)** * 控制服务网格内的网络流量流。 * 配置 sidecar 注入。 * 使用 Gateway 资源配置入口和出口流量。 * 了解如何使用 ServiceEntry 资源向内部服务注册表添加条目。 * 使用 DestinationRule 定义流量策略。 * 配置流量镜像功能。 3. **弹性与故障注入 (20%)** * 配置断路器（可带或不带离群检测）。 * 使用弹性功能。 * 进行故障注入。 4. **安全工作负载 (20%)** * 理解 Istio 安全特性。 * 在网格中为 HTTP/TCP 流量设置 Istio 授权。 * 配置网格、命名空间和工作负载级别的双向 TLS。 5. **高级场景 (13%)** * 理解如何将非 Kubernetes 工作负载接入网格。 * 排查配置问题。 **课程大纲：** (无具体 Syllabus 提供)
IMPORTANT before enrolling:Actual Istio Certified Associate (ICA) from LinuxFoundation is Time-based and Performance-based (Lab/practical). And this practice question is just to give a familiarity for real time questions of the exam.As current portal is not supporting lab session, only relevant questions with great explanations are updated in this course.As real exam is time-based and lab/practical/performance based - you can get real answer only after submission of test and have a looks on how the solution can be helpful to solve the real exam.Suggestion - For practice lab, you can use your own Kubernetes cluster, and perform the similar exercise on the BookInfo Application, which is already bundled under Istio installation. In case, if you are planning to instructor led training program for the Istio from scratch, feel free to drop message on Instrucor's LinkedIn profile. My team will update you for the next upcoming batches on the same, with details.Actual Exam - ICAThe Istio Certified Associate (ICA) exam demonstrates a solid understanding of Istio principles, terminology, and best practices in order to set up Istio.Who is it for?The ICA is a pre-professional certification designed for engineers, CI/CD practitioners or anyone with special interests in Istio.What does the ICA Demonstrate?An ICA can comprehend GitOps patterns including when and why to use them. They understand the precautions to take around tooling for manifest format and packaging, state store systems, and reconciliation engines to adhere to and extend GitOps principles.Domains and Competencies -Istio Installation, Upgrade and Configuration (7%)Using the Istio CLI to install a basic clusterCustomizing the Istio installation with the IstioOperator APIUsing overlays to manage Istio component settingsTraffic Management (40%)Controlling network traffic flows within a service meshConfiguring sidecar injectionUsing the Gateway resource to configure ingress and egress trafficUnderstanding how to use ServiceEntry resources for adding entries to internal service registryDefine traffic policies using DestinationRuleConfigure traffic mirroring capabilitiesResilience and Fault Injection (20%)Configuring circuit breakers (with or without outlier detection)Using resilience featuresCreating fault injectionSecurity Workloads (20%)Understand Istio security featuresSet up Istio authorization for HTTP/TCP traffic in the meshConfigure mutual TLS at mesh, namespace, and workload levelsAdvanced Scenarios (13%)Understand how to onboard non-Kubernetes workloads to the meshTroubleshoot configuration issues
