Explanation
What is Apache Spark notebook?
A notebook is a collection of cells. These cells are run to execute code, to render formatted text, or to display graphical visualizations.
What is a cluster?
The notebooks are backed by clusters, or networked computers, that work together to process your data. The first step is to create a cluster.
A. Apache Spark notebook is a collection of cells that can contain code, formatted text, or visualizations. These cells can be executed individually to interactively work with data and analyze results.
B. This choice describes the logical environment in Azure Databricks, which is not specifically related to Apache Spark notebooks. It focuses on cluster creation, data storage, and server resources within the Azure Databricks platform.
C. This choice refers to the Time to Live (TTL) property for records stored in an analytical store, which is not directly related to the concept of Apache Spark notebooks. It focuses on data lifecycle management rather than notebook functionality.
D. This choice describes a cloud-based Big Data and Machine Learning platform, which is a general description of Azure Databricks rather than specifically defining what an Apache Spark notebook is.
