Understand the certification
Google Cloud Certified - Professional Cloud DevOps Engineer 验证你在 GCP 上构建 CI/CD 管道、实施 SRE 实践和优化服务可靠性的能力。考试 50-60 题，120 分钟，及格线约 70%，考试费 $200 USD。
与 AWS DOP-C02 的最大区别：GCP DevOps 考试深度绑定 Google 的 SRE 方法论 — SLI/SLO/Error Budget 不是"加分知识"而是"必考核心"，约 23% 的题目直接考 SRE 实践。另外 23% 考 CI/CD（Cloud Build + Artifact Registry + Cloud Deploy），20% 考监控（Cloud Monitoring + Cloud Logging + Cloud Trace），17% 考服务性能优化。
Google 在 2024 年更新了考纲，新增对 Cloud Deploy 的渐进式交付（canary deployment）和 Service Mesh（Anthos Service Mesh）的考查。

1. 第一阶段：SRE 理论基础（2 周）
读 Google SRE Book 的核心章节：SLI/SLO/Error Budget 的定义和计算、Toil 消除策略、Incident Management 流程。理解 Error Budget 的概念 — 比如 99.9% SLO 意味着每月允许 43 分钟不可用。
2. 第二阶段：CI/CD 管道（2 周）
Cloud Build 的 cloudbuild.yaml 编写（steps/images/artifacts）、Artifact Registry 镜像管理、Cloud Deploy 的 delivery pipeline + target 配置、canary deployment 的流量分配策略。
3. 第三阶段：监控 + 日志 + 性能（2 周）
Cloud Monitoring 的 alerting policy 配置（条件/通知渠道/文档）、Uptime Checks、Cloud Trace 延迟分析、Cloud Profiler CPU/内存分析。重点是"给你一个延迟飙升的场景，用什么工具排查"。
4. 第四阶段：模考（1 周）
Google 官方 Practice Exam + Whizlabs 做 2-3 套。GCP 考试的题目表述比 AWS 更简洁，但选项之间的差异更细微。
Career value
SRE 岗位的认证需求
Google 是 SRE 这个概念的发明者，GCP DevOps Engineer 认证自然成为 SRE 岗位最对口的云认证。在 LinkedIn 搜索"SRE + GCP"的澳洲职位，约 60% 的 JD 提到"GCP certification preferred"。
适合考的人：已经在 GCP 上做运维/平台工程的工程师，以及读完《Site Reliability Engineering》想拿一个实践验证的人。
不适合考的人：没有 GCP 实操经验的人。这个考试的场景题假设你知道 Cloud Monitoring 的 MQL（Monitoring Query Language）语法和 Cloud Logging 的过滤表达式。

Preparation tips
- **SRE 题占 23%**：这是与其他云 DevOps 认证最大的区别，如果你不理解 Error Budget 概念，会丢约 1/4 的分。
- **"Least operational overhead" 选托管服务**：GKE Autopilot > GKE Standard > Compute Engine。
- **Anthos 基础概念**：知道 Anthos 是多云/混合云管理平台，Anthos Service Mesh 基于 Istio。不需要深入配置细节。
Common mistakes
- **SLO 和 SLA 混淆** — SLO 是内部目标（99.9%），SLA 是对客户的合同承诺（通常比 SLO 宽松，如 99.5%）。违反 SLO 触发内部响应，违反 SLA 触发赔偿。
- **Binary Authorization 忽视** — 考试会问"如何确保只有经过签名验证的镜像才能部署到 GKE"，答案是 Binary Authorization。
- **Cloud Deploy vs Cloud Build** — Cloud Build 负责构建和测试，Cloud Deploy 负责交付到目标环境（dev/staging/prod）。两者是互补不是替代。
Before you register
How difficult is the GCP Professional Cloud DevOps Engineer exam?
The DevOps Engineer is a Professional-level certification with a relatively high difficulty level. The exam heavily tests CI/CD pipeline design and SRE practices, each accounting for 23% of the exam. You need a deep understanding of services like Cloud Build, GKE, and Cloud Monitoring.
Should I take the DevOps Engineer or PCA exam first?
If your work focuses more on operations and continuous delivery, consider taking DevOps Engineer first. If it leans toward architecture design, PCA may be a better starting point. The two have some knowledge overlap, particularly around GKE and monitoring.
Does SRE content account for a large portion of the exam?
Yes, SRE-related content accounts for approximately 23%, making it one of the highest-weighted domains. You need to master SLI/SLO/SLA definitions, Error Budget management, incident response processes, and Postmortem practices.
How long is the DevOps Engineer certification valid?
The GCP Professional Cloud DevOps Engineer certification is valid for 2 years. The exam fee is $200 USD, the duration is 120 minutes, and the passing score is approximately 70%.
Do I need to know Kubernetes for this exam?
Yes. GKE is one of the core services on the exam. You need to understand GKE cluster management, deployment strategies, Pod configuration, autoscaling, and security best practices. You do not need CKA/CKAD-level depth, but you must be proficient with GKE-specific features.

SLI/SLO 的计算题出了 4-5 道，比如"每月 Error Budget 剩余 15%，是否应该暂停发布" — 答案取决于 Error Budget Policy 怎么定义的。读 Google SRE Workbook 第 2-4 章比刷题有效。

AWS 经验帮助不大，GCP 的工具链完全不同。Cloud Build 不像 CodePipeline 那么图形化，基本靠 YAML 配置。花了 2 周专门学 Cloud Build + Cloud Deploy 的组合。
