Certified Data Analyst Associate Practice Test practice questions, page 2 of 6, with answer review and explanations.
Question 6
A data analyst has set up a SQL query to run every four hours on a SQL endpoint, but the SQL endpoint is taking too long to start up with each run. Which of the following changes can the data analyst make to reduce the start-up time for the endpoint while managing costs?
Reduce the SQL endpoint cluster size
Increase the SQL endpoint cluster size
Turn off the Auto stop feature
Increase the minimum scaling value
Use a Serverless SQL endpoint
Question 7
A data engineering team has created a Structured Streaming pipeline that processes data in micro-batches and populates gold-level tables. The microbatches are triggered every minute. A data analyst has created a dashboard based on this gold-level data. The project stakeholders want to see the results in the dashboard updated within one minute or less of new data becoming available within the gold-level tables. Which of the following cautions should the data analyst share prior to setting up the dashboard to complete this task?
The required compute resources could be costly
The gold-level tables are not appropriately clean for business reporting
The streaming data is not an appropriate data source for a dashboard
The streaming cluster is not fault tolerant
The dashboard cannot be refreshed that quickly
Question 8
Which of the following approaches can be used to ingest data directly from cloud-based object storage?
Create an external table while specifying the DBFS storage path to FROM
Create an external table while specifying the DBFS storage path to PATH
It is not possible to directly ingest data from cloud-based object storage
Create an external table while specifying the object storage path to FROM
Create an external table while specifying the object storage path to LOCATION
Question 9
A data analyst wants to create a dashboard with three main sections: Development, Testing, and Production. They want all three sections on the same dashboard, but they want to clearly designate the sections using text on the dashboard. Which of the following tools can the data analyst use to designate the Development, Testing, and Production sections using text?
Separate endpoints for each section
Separate queries for each section
Markdown-based text boxes
Direct text written into the dashboard in editing mode
Separate color palettes for each section
Question 10
A data analyst needs to use the Databricks Lakehouse Platform to quickly create SQL queries and data visualizations. It is a requirement that the compute resources in the platform can be made serverless, and it is expected that data visualizations can be placed within a dashboard. Which of the following Databricks Lakehouse Platform services/capabilities meets all of these requirements?
