Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Modify the global ConfigMap in the Argo CD namespace
Why it's wrong here
ConfigMaps are not used for storing cluster credentials for security reasons.
- ✗
Add the cluster URL to the Git repository manifest
Why it's wrong here
Git repository manifests should not contain sensitive cluster authentication credentials.
- ✓
Use the argocd cluster add command to store credentials as a secret in the Argo CD namespace
Why this is correct
This is the standard, secure way to register a remote cluster for GitOps management.
- ✗
Manually create a Kubernetes secret in the remote cluster
Why it's wrong here
The secret must exist in the cluster where Argo CD is installed, pointing to the remote API server.
