# In Argo CD 3.6, which diff strategy do Applications with the ServerSideApply=true sync option use by default?

Argo CD, Easy (Beginner), Syncing & Deployment. https://k8wiz.com/uquiz/in-argo-cd-36-which-diff-strategy-do-applications-with-the-serversideapplytrue-sync-option-use-by-default

- A. Legacy client-side diff
- B. Server-Side Diff
- C. Structured-Merge Diff
- D. Three-way merge diff

**Answer:** Server-Side Diff

**Explanation:** Argo CD 3.6 turns on Server-Side Diff for every Application that uses the ServerSideApply=true sync option. It runs a Server-Side Apply dry run against the API server and compares the result with the live object. The Structured-Merge Diff strategy those Applications used before has been removed.
