질문 # 101
You are currently working on a production job failure with a job set up in job clusters due to a data issue, what cluster do you need to start to investigate and analyze the data?

A. All-purpose cluster/ interactive cluster is the recommended way to run commands and view the data.
B. A Job cluster can be used to analyze the problem
C. Databricks SQL Endpoint can be used to investigate the issue
D. Existing job cluster can be used to investigate the issue

정답：A

설명：
Explanation
Answer is All-purpose cluster/ interactive cluster is the recommended way to run commands and view the data.
A job cluster can not provide a way for a user to interact with a notebook once the job is submitted, but an Interactive cluster allows to you display data, view visualizations write or edit quries, which makes it a perfect fit to investigate and analyze the data.

질문 # 102
The data governance team is reviewing user for deleting records for compliance with GDPR. The following logic has been implemented to propagate deleted requests from the user_lookup table to the user aggregate table.

Assuming that user_id is a unique identifying key and that all users have requested deletion have been removed from the user_lookup table, which statement describes whether successfully executing the above logic guarantees that the records to be deleted from the user_aggregates table are no longer accessible and why?

A. No: the Delta Lake DELETE command only provides ACID guarantees when combined with the MERGE INTO command
B. No: the change data feed only tracks inserts and updates not deleted records.
C. Yes: Delta Lake ACID guarantees provide assurance that the DELETE command successed fully and permanently purged these records.
D. No: files containing deleted records may still be accessible with time travel until a BACUM command is used to remove invalidated data files.

정답：D

설명：
The DELETE operation in Delta Lake is ACID compliant, which means that once the operation is successful, the records are logically removed from the table. However, the underlying files that contained these records may still exist and be accessible via time travel to older versions of the table. To ensure that these records are physically removed and compliance with GDPR is maintained, a VACUUM command should be used to clean up these data files after a certain retention period. The VACUUM command will remove the files from the storage layer, and after this, the records will no longer be accessible.

질문 # 103
Why does AUTO LOADER require schema location?

A. Schema location is used to identify the schema of target table
B. Schema location is used to identify the schema of target table and source table
C. Schema location is used to store schema inferred by AUTO LOADER
D. AUTO LOADER does not require schema location, because its supports Schema evolution
E. Schema location is used to store user provided schema

정답：C

설명：
Explanation
The answer is, Schema location is used to store schema inferred by AUTO LOADER, so the next time AUTO LOADER runs faster as does not need to infer the schema every single time by trying to use the last known schema.
Auto Loader samples the first 50 GB or 1000 files that it discovers, whichever limit is crossed first. To avoid incurring this inference cost at every stream start up, and to be able to provide a stable schema across stream restarts, you must set the option cloudFiles.schemaLocation. Auto Loader creates a hidden directory _schemas at this location to track schema changes to the input data over time.
