20+ practice questions focused on Data Sharing and Federation — one of the most tested topics on the Databricks Certified Data Engineer Professional exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Data Sharing and Federation PracticeRefer to the exhibit. A Data Engineer wants to share only the North American data from the 'revenue' table with 'partner_corp'. The user observes that the recipient is still seeing all regional data. What is the cause of this behavior?
Explanation: In Unity Catalog, partition filters are applied using the 'ALTER SHARE ... ADD TABLE ... PARTITION (...)' command, not a generic 'ALTER SHARE' command. Furthermore, the exhibit (implied) likely shows a misconfiguration where the filter was not applied correctly during the ADD TABLE phase or the ALTER SHARE command was never executed. Option A is misleading because 'ALTER SHARE' alone does not apply a filter; the filter is part of the table addition/modification syntax.
Refer to the exhibit. A user is attempting to access a Delta Sharing share but receives this error. What is the most likely cause?
Explanation: Delta Sharing tokens have an expiration period. When a token expires, the recipient can no longer authenticate with the provider's Delta Sharing server, resulting in a 401 Unauthorized error. The Data Engineer must rotate the token and provide a new credential file to the recipient. This security measure prevents long-term unauthorized access and ensures that recipients must periodically renew their access permissions to continue querying the shared datasets.
A Data Engineer is configuring a new Delta Share. Which THREE requirements must be satisfied for the recipient to access the data successfully?
Explanation: The three requirements for Delta Sharing are: 1) The provider must create a share and add tables to it (D), 2) The provider must create a recipient object and grant them access to the share (B), and 3) The recipient must use the activation link/credential file provided by the provider to authenticate (A). Option C is incorrect because Delta Sharing is an open protocol and does not require the recipient to have a Databricks account.
Refer to the exhibit. A Data Engineer applied these permissions, but the users in the 'data_analysts' group still cannot query the tables. What is the missing step?
Explanation: In Unity Catalog, to access a table, a user needs USAGE on the Catalog, USAGE on the Schema, and SELECT on the Table. The explanation incorrectly states that USAGE on the connection is required for catalog access (connections are for Lakehouse Federation, not standard catalog access) and incorrectly claims the exhibit grants SELECT on the catalog (which is not a valid privilege for a catalog).
A Data Engineer is configuring a Databricks-to-Databricks Delta Share for a partner who uses a Unity Catalog-enabled workspace in a different Databricks account. The engineer has created the share, added the table, and granted the recipient access. The partner reports that they can see the share but cannot query the table. The engineer verifies that the recipient has been granted SELECT on the share. What is the most likely cause?
Explanation: For a Databricks-to-Databricks share, the recipient must be granted USE on the share and SELECT on the table. Without USE on the share, the recipient cannot access the share at all. Without SELECT on the table, they cannot query the table. The scenario indicates the recipient can see the share but cannot query the table, pointing to missing SELECT on the table or missing USE on the share. The correct answer identifies the required privileges.
