Apache Spark Certification Practice Test

To start PySpark on Windows, the correct command is "pyspark" entered in the command prompt. This command initializes the PySpark shell, loading the necessary configurations and setup to run PySpark applications directly in an interactive environment. When executed, it allows users to write and execute Spark applications using Python, making it a vital entry point for those developing data processing pipelines or performing analysis with Spark.

The option mentioning "pyspark command" correctly refers to the actual command without any additional phrases or modifiers that could create ambiguity, emphasizing the straightforward nature of invoking PySpark. The command can be run directly after ensuring that Apache Spark and any necessary environment variables are correctly set up in the Windows operating system.

Other options, while indicating actions that may be associated with starting PySpark, do not accurately represent the command needed. They introduce variations or modifications that do not align with the accepted command used for this purpose.
