We are asked to execute kubectl create clusterrolebinding add-on-cluster-admin ......... but we are not aware how to use this and login to the created cluster in Azure

Answer 1

you can use this quick start tutorial: https://learn.microsoft.com/en-us/azure/aks/kubernetes-walkthrough#connect-to-the-cluster
basically you need to install kubectl:
az aks install-cli
and pull credentials for AKS:
az aks get-credentials --resource-group myResourceGroup --name myAKSCluster

Answer 2

As per ducemtaion:
User accounts vs service accounts
Kubernetes distinguishes between the concept of a user account and a service account for a number of reasons:
User accounts are for humans. Service accounts are for processes, which run in pods.
User accounts are intended to be global. Names must be unique across all namespaces of a cluster, future user resource will not be namespaced. Service accounts are namespaced.
Typically, a cluster’s User accounts might be synced from a corporate database, where new user account creation requires special privileges and is tied to complex business processes. Service account creation is intended to be more lightweight, allowing cluster users to create service accounts for specific tasks (i.e. principle of least privilege).
Auditing considerations for humans and service accounts may differ.
A config bundle for a complex system may include definition of various service accounts for components of that system. Because service accounts can be created ad-hoc and have namespaced names, such config is portable.
As an example:
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
name: secret-reader
rules:
- apiGroups: [""]
resources: ["secrets"]
verbs: ["get", "watch", "list"]
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: read-secrets-global
subjects:
- kind: User
name: manager
apiGroup: rbac.authorization.k8s.io
roleRef:
kind: ClusterRole
name: secret-reader
apiGroup: rbac.authorization.k8s.io
