Samir:
Question: How many applications do you see hosted on the cluster?
Check the number of deployments
root@controlplane:~# kubectl get deployments --all-namespaces
NAMESPACE NAME READY UP-TO-DATE AVAILABLE AGE
default blue 0/3 3 0 19s
kube-system coredns 2/2 2 2 2m44s
Why is the correct answer 1 ?
