Where does lab data come from?

Going through the exercise (for the DP-203)
https://docs.microsoft.com/en-us/learn/modules/use-data-loading-best-practices-azure-synapse-analytics/9-exercise-implement-workload-management

Suddenly the instructions says
"Select the Lab 08 - Execute Data Analyst and CEO Queries Pipeline"

Where does this pipeline come from? Is there lab data/environment available somewhere?
