Understand the certification

正在部署或运维 Cisco ACI 的数据中心工程师强烈建议考,不用 ACI 的人可以跳过。

300-620 DCACI(Implementing Cisco Application Centric Infrastructure)是 CCNP Data Center 的 ACI 实施专项,60 题 / 90 分钟。这是所有 CCNP DC 专项中题库最大(300+ 练习题)的一门。

Cisco ACI 是 Cisco 的 SDN(软件定义网络)数据中心解决方案,核心组件是 APIC(Application Policy Infrastructure Controller)控制器 + Nexus 9000 Spine/Leaf 交换机。考试围绕 ACI 的对象模型:Tenant → VRF → Bridge Domain → EPG → Contract,以及外部网络集成(L3Out / L2Out)。

约 30% 的题考 ACI Fabric 初始化(APIC Discovery、Fabric Membership、Switch Profile/Interface Profile)。20% 考 Multi-Pod 和 Multi-Site 架构。Contract 和 Filter 的配置逻辑是考试的核心难点 — ACI 的白名单模型(deny-all by default)和传统网络的 ACL 思维完全相反。

Included in your preparation

  • 7 structured chapters covering the exam domains
  • 305 practice questions with explanations
  • Mock exam practice for timed review
  • A practical ACI implementation study path
  • Coverage of fabric setup, access policies, tenant policies, and advanced features

1. 第一阶段:ACI 对象模型和 Fabric 初始化(2-3 周)

理解 ACI 的 MIT(Management Information Tree)对象模型层级。练习 APIC 初始化、Fabric Discovery、Switch Profile 和 Interface Profile 配置。Cisco 提供免费 ACI Simulator(需要申请),是练习的最佳工具。

2. 第二阶段:Contract/EPG + 外部集成(2-3 周)

EPG 到 EPG 的 Contract 配置(Provider/Consumer 模型、Filter Entry 定义)。L3Out 外部路由集成(OSPF/BGP/Static Route)。L4-L7 Service Graph(防火墙/负载均衡器插入)。这是考试最难的部分。

3. 第三阶段:Multi-Pod/Multi-Site + 模考(1-2 周)

Multi-Pod(IPN 连接、TEP Pool 规划)和 Multi-Site Orchestrator(MSO)的基本配置。做 2-3 套模考,Contract 和 L3Out 配置题是丢分重灾区。

Career value

ACI 是 Cisco 在 SDN 数据中心市场的主力产品,全球部署量超过 5 万套。金融、电信、大型企业的数据中心改造项目中 ACI 是常见选项。

适合考的人:在 ACI 环境中工作或即将参与 ACI 部署项目的 DC 工程师。Cisco 合作伙伴的 DC 专业化认证通常要求有 DCACI 持证人。

不适合考的人:使用 VXLAN EVPN(非 ACI 模式)或 VMware NSX 做数据中心网络的人。

Preparation tips

    Common mistakes

    • **用传统 ACL 思维理解 Contract** — ACI 是白名单模型,默认 deny-all。Contract 定义的是"允许什么流量",方向是 Consumer → Provider。这和传统 ACL 的 deny/permit 列表逻辑不同。
    • **L3Out 配置步骤不熟** — L3Out 涉及 Node Profile → Interface Profile → External EPG 多层配置,考试给半成品让你补全剩余配置。
    • **忽略 ACI REST API** — 约 5% 的题考 APIC REST API 调用(用 JSON/XML 配置对象),不能完全不准备。

    Learner experiences

    Loading reviews…

    ACI 的思维方式和传统网络完全不同 — 先定义 EPG 和 Contract(应用策略),再绑定物理端口。考试里 Contract 的 Provider/Consumer 方向问题至少出了 8 道。一定要在 ACI Simulator 上多练。
