In cluster mode, the driver runs on the master node, while in client mode, the driver runs on a virtual machine in the cloud.

This is wrong, since execution modes do not specify whether workloads are run in the cloud or on-premise.

In cluster mode, each node will launch its own executor, while in client mode, executors will exclusively run on the client machine.

Wrong, since in both cases executors run on worker nodes.

In cluster mode, the driver runs on the edge node, while the client mode runs the driver in a worker node.

Wrong – in cluster mode, the driver runs on a worker node. In client mode, the driver runs on the client machine.

In client mode, the cluster manager runs on the same host as the driver, while in cluster mode, the cluster manager runs on a separate node.

No. In both modes, the cluster manager is typically on a separate node – not on the same host as the driver. It only runs on the same host as the driver in local execution mode.
