PySpark and AWS: Master Big Data with PySpark and AWS - Quiz (Word Count) - Spark RDDs

The video introduces a quiz based on previously learned concepts. It provides instructions for using files in the quiz, emphasizing that the same file in Databricks storage is not mandatory. The task involves reading a file into an RDD and writing a transformation flow to return the word count of each word as a key-value pair. The video concludes by stating that the solution will be discussed in the next video.
