What does the spark stand alone cluster do?

Hello.

My question here is what the spark stand alone cluster do here. Because when
we submit program like below

    ./bin/spark-submit   --master spark://ES01:7077 --executor-memory 4G
--num-executors 1 --total-executor-cores 1 --conf
"spark.storage.memoryFraction=0.2" 


We specified the resource allocation manually
We specified the config manually 

Then what the cluster do here?
