Databricks Certified Data Analyst Associate — Question 31

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?

Answer options

• A. The required compute resources could be costly
• B. The gold-level tables are not appropriately clean for business reporting
• C. The streaming data is not an appropriate data source for a dashboard
• D. The streaming cluster is not fault tolerant
• E. The dashboard cannot be refreshed that quickly

Correct answer: A

Explanation

The correct answer is A because achieving real-time updates on the dashboard may require significant compute resources, which can lead to high costs. The other options either do not directly address the immediate concern of cost associated with fast updates or are not valid issues with the current setup.
