Alistair Mackay:
etcdctl will be installed somewhere which may be the master/controlplane or the node you are on when the lab starts.

If it is not installed on the same node where the etcd daemon/pod is running, then you need to use --endpoints to point it to the correct node.

If you’re doing a kodekloud lab/killer.sh/real exam question about etcd backup, then for etcdctl not to be present would be an error in the environment.

Vitor Jr.:
@Akash Saha, during the exam, you will have access to a client with etcd installed or have to ssh to control-plane and execute the backup command. Like @Alistair Mackay said, remember the --endpoints parameter and check etcd.yaml to confirm which endpoint values are available.
