Session 8 Part 3 Quiz (Local PySpark Setup)

Question 1

Why does local PySpark need Java?

  • Spark runs on the Java Virtual Machine
  • Java replaces Python syntax
  • Java stores the quiz answers
  • Java is only needed for Markdown files

Answer: 1 Type: single Time: 45 Explanation: Local Spark uses the JVM, and PySpark communicates with it from Python.

Question 2

Which command checks the installed Java version?

  • java -version
  • pip java
  • python java
  • spark version java

Answer: 1 Type: single Time: 40 Explanation: java -version prints the Java version if Java is installed.

Question 3

Why create a virtual environment?

  • To keep this session's Python dependencies separate
  • To delete Java
  • To make Colab mandatory
  • To convert Markdown to SQL

Answer: 1 Type: single Time: 45 Explanation: A virtual environment isolates project packages.

Question 4

Which command installs the session requirements?

  • pip install -r requirements.txt
  • python requirements.txt
  • java install requirements.txt
  • git install requirements.txt

Answer: 1 Type: single Time: 45 Explanation: pip install -r requirements.txt installs packages listed in the requirements file.

Question 5

Where should students run python3 solutions/exercise-08-03.py from?

  • Inside the session8 folder
  • Inside the .git folder
  • From Google search
  • From the operating system trash

Answer: 1 Type: single Time: 45 Explanation: Running from session8 keeps relative paths and session instructions simple.

Question 6

What should the local verification script do?

  • Start Spark, create a small DataFrame, summarize it, and stop Spark
  • Delete the virtual environment
  • Upload all files to Colab
  • Install pandas only

Answer: 1 Type: single Time: 50 Explanation: The local script checks that PySpark can start and run a small job.

Question 7

What should you check first if PySpark cannot start locally?

  • Whether Java works with java -version
  • Whether the quiz title is long enough
  • Whether the notebook has emojis
  • Whether SQL keywords are lowercase

Answer: 1 Type: single Time: 45 Explanation: Missing or incompatible Java is a common local Spark setup issue.

Question 8

Which file lists the local dependencies for Session 8?

  • requirements.txt
  • README.sql
  • spark.lock
  • java.md

Answer: 1 Type: single Time: 40 Explanation: The requirements file lists packages to install with pip.

Question 9

What does spark.stop() do in the local verification script?

  • Releases the Spark session resources
  • Deletes requirements.txt
  • Removes Java from the computer
  • Converts the script into a notebook

Answer: 1 Type: single Time: 45 Explanation: spark.stop() shuts down the Spark session created by the script.

Question 10

If Python says it cannot find solutions/exercise-08-03.py, what should you check?

  • That you are running the command from inside the session8 folder
  • That SQL has a GROUP BY
  • That Colab is closed
  • That the file has exactly 12 rows

Answer: 1 Type: single Time: 45 Explanation: The command in the tutorial assumes the terminal is currently inside session8.
