[@peternan4814]

Thank you sir for sharing your knowledge! I passed the exam today, most of the questions are the same with your video. However, the two parts differ: 1) the total number of questions increases to 50. 2). The number of options is ABCD without E.

[@joshuadanielmendoza312]

A data engineer wants to create a relational object by pulling data from two tables. The relational object must be used by other data engineers in other sessions on the same cluster only. In order to save on storage costs, the data engineer wants to avoid copying and storing physical data. The correct answer is Global Temporary view? or VIEW only?

[@RakeshKumar-dq3db]

View only. Here, the keyword is other sessions. GlobalTemlViews are restricted to that particular session only that means if the cluster is restarted it won't be available any more but the VIEW will remain even in the other sessions.

[@MuhammadUmer-ev8pk]

@@RakeshKumar-dq3db no Global Temp Views are not restricted to a session instead they are restricted to a cluster so any notebook attached with that cluster can use Global Temp Views as long as the cluster is running. Glob Temp is a temp database associated with a cluster.
