Sample Questions on DP-203 Certification

Domain : Design and implement data storage

Q2 : You are working on Azure Data Lake Store Gen1. Suddenly, you realize the need to know the schema of the external data. Which of the following plug-in would you use to know the external data schema?

A. Ipv4_lookup
B. Mysql_request
C. Pivot
D. Narrow
E. infer_storage_schema

Correct Answer: E

Explanation:

infer_storage_schema is the plug-in that helps infer the schema based on the external file contents; when the external data schema is unknown.

Option A is incorrect. The ipv4_lookup plugin checks for an IPv4 value in a lookup table and returns the matched rows.

Option B is incorrect. The mysql_request plugin transfers a SQL query to a MySQL Server network endpoint and returns the 1st row set in the result.

Option C is incorrect. Pivot plug-in is used to rotate a table by changing the unique values from 1 column in the input table into a number of different columns in the output table and perform aggregations wherever needed on any remaining column values that are desired in the final output.

Option D is incorrect. This plug-in is used to unpivot a wide table into a table with only three columns.

Option E is correct. infer_storage_schema plug-in can be used to infer the schema of external data and return it as a CSL schema string.

Domain : Design and implement data security

Q3 :  You work in Azure Synapse Analytics dedicated SQL pool that has a table titled Pilots. Now you want to restrict the user access in such a way that users in ‘IndianAnalyst’ role can see only the pilots from India.  Which of the following would you add to the solution?

A. Table partitions
B. Encryption
C. Column-Level security
D. Row-level security
E. Data Masking

Correct Answer: D

Explanation:

Row-level security is applicable on databases to allow fine-grained access to the rows in a database table for restricted control upon who could access which type of data.

Option A is incorrect. Table partitions are generally used to group similar data.

Option B is incorrect. Encryption is used for security purposes.

Option C is incorrect. Column level security is used to restrict data access at the column level. In the given scenario, we need to restrict access at the row level.

Option D is correct. In this scenario, we need to restrict access on a row basis, i.e only for the pilots from India, there Row-level security is the right solution.

Option E is incorrect. Sensitive data exposure can be limited by masking it to unauthorized users using SQL Database dynamic data masking.
