Using 'default' namespace instead of 'argocd'.

Using 'kube-system' which is reserved for system components.

The namespace argocd is the default namespace where ArgoCD is installed.

💡 Hint

Common Mistakes

Using a URL that points to unrelated manifests.

Using a URL for deletion instead of installation.

💡 Hint

Common Mistakes

Using incorrect service names that do not exist.

Swapping the order of words in the service name.

The ArgoCD server service is named argocd-server in the argocd namespace.

Fill both blanks to create an ArgoCD application manifest snippet that syncs from a Git repo.

Kubernetes

"apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: guestbook
spec:
  source:
    repoURL: [1]
    path: guestbook
  destination:
    server: [2]

💡 Hint

Common Mistakes

Using incorrect or non-existent Git repo URLs.

Using external URLs instead of the Kubernetes API server URL.

The repoURL should point to the official ArgoCD example apps repository. The destination.server is the internal Kubernetes API server URL https://kubernetes.default.svc.

hard

Fill both blanks to complete the command to log into ArgoCD CLI with the admin password from the secret.

Kubernetes

argocd login localhost:[1] --username admin --password $(kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | [2])

Drag options to blanks, or click blank then click option'

D80

💡 Hint

Common Mistakes

Using wrong port numbers like 80.

Using incorrect base64 decoding flags.

Not decoding the password from base64.

The ArgoCD server usually listens on port 8080 locally. The password is stored base64 encoded in the secret under .data.password and must be decoded with base64 --decode.
