Databricks Certified Data Engineer Associate Exam Sample Questions (Q31-Q36):

NEW QUESTION # 31
A data engineer only wants to execute the final block of a Python program if the Python variable day_of_week is equal to 1 and the Python variable review_period is True.
Which of the following control flow statements should the data engineer use to begin this conditionally executed code block?

  • A. if day_of_week = 1 and review_period:
  • B. if day_of_week == 1 and review_period:
  • C. if day_of_week = 1 & review_period: = "True":
  • D. if day_of_week == 1 and review_period == "True":
  • E. if day_of_week = 1 and review_period = "True":

Answer: B

Explanation:
Explanation
This statement will check if the variable day_of_week is equal to 1 and if the variable review_period evaluates to a truthy value. The use of the double equal sign (==) in the comparison of day_of_week is important, as a single equal sign (=) would be used to assign a value to the variable instead of checking its value. The use of a single ampersand (&) instead of the keyword and is not valid syntax in Python. The use of quotes around True in options B and C will result in a string comparison, which will not evaluate to True even if the value of review_period is True.


NEW QUESTION # 32
A new data engineering team has been assigned to work on a project. The team will need access to database customers in order to see what tables already exist. The team has its own group team.
Which of the following commands can be used to grant the necessary permission on the entire database to the new team?

  • A. GRANT CREATE ON DATABASE team TO customers;
  • B. GRANT USAGE ON DATABASE customers TO team;
  • C. GRANT CREATE ON DATABASE customers TO team;
  • D. GRANT VIEW ON CATALOG customers TO team;
  • E. GRANT USAGE ON CATALOG team TO customers;

Answer: B

Explanation:
The correct command to grant the necessary permission on the entire database to the new team is to use the GRANT USAGE command. The GRANT USAGE command grants the principal the ability to access the securable object, such as a database, schema, or table. In this case, the securable object is the database customers, and the principal is the group team. By granting usage on the database, the team will be able to see what tables already exist in the database. Option E is the only option that uses the correct syntax and the correct privilege type for this scenario. Option A uses the wrong privilege type (VIEW) and the wrong securable object (CATALOG). Option B uses the wrong privilege type (CREATE), which would allow the team to create new tables in the database, but not necessarily see the existing ones. Option C uses the wrong securable object (CATALOG) and the wrong principal (customers). Option D uses the wrong securable object (team) and the wrong principal (customers). References: GRANT, Privilege types, Securable objects, Principals


NEW QUESTION # 33
A data engineer wants to create a data entity from a couple of tables. The data entity must be used by other data engineers in other sessions. It also must be saved to a physical location.
Which of the following data entities should the data engineer create?

  • A. View
  • B. Database
  • C. Function

Answer: A


NEW QUESTION # 34
A data engineer has been given a new record of data:
id STRING = 'a1'
rank INTEGER = 6
rating FLOAT = 9.4
Which of the following SQL commands can be used to append the new record to an existing Delta table my_table?

  • A. INSERT VALUES ( 'a1' , 6, 9.4) INTO my_table
  • B. UPDATE VALUES ('a1', 6, 9.4) my_table
  • C. my_table UNION VALUES ('a1', 6, 9.4)
  • D. INSERT INTO my_table VALUES ('a1', 6, 9.4)
  • E. UPDATE my_table VALUES ('a1', 6, 9.4)

Answer: D

Explanation:
To append a new record to an existing Delta table, you can use the INSERT INTO statement with the VALUES clause. This statement will insert one or more rows into the table with the specified values. Option A is the only code block that follows this syntax correctly. Option B is incorrect, as it uses the UNION operator, which will return a new table that is the union of two tables, not append to an existing table. Option C is incorrect, as it uses the INSERT VALUES statement, which is not a valid SQL syntax. Option D is incorrect, as it uses the UPDATE statement, which will modify existing rows in the table, not append new rows. Option E is incorrect, as it uses the UPDATE VALUES statement, which is also not a valid SQL syntax.
