# Which of the following is NOT a core component of Argo CD?

Argo CD, Medium (Advanced), Architecture. https://k8wiz.com/uquiz/which-of-the-following-is-not-a-core-component-of-argo-cd

- A. API Server
- B. Repository Server
- C. Application Controller
- D. Deployment Engine

**Answer:** Deployment Engine

**Explanation:** Argo CD consists of three core components: the API Server (REST API, web UI, gRPC/CLI), the Repository Server (maintains Git repositories), and the Application Controller (monitors applications and compares current state with desired state). There is no component called 'Deployment Engine' in Argo CD's architecture.
