Sample Question with Explanation from Cert4Prep

Question:1 (Single Select) Choose the best answer.

Examine the description of the EMPLOYEES table:

Which query is valid?

A: SELECT dept_id, join_date,SUM(salary) FROM employees GROUP BY dept_id, join_date;

B: SELECT depe_id,join_date,SUM(salary) FROM employees GROUP BY dept_id:

C: SELECT dept_id,MAX(AVG(salary)) FROM employees GROUP BY dept_id;

D: SELECT dept_id,AVG(MAX(salary)) FROM employees GROUP BY dapt_id;

Correct Answer: A

Explanation:

In Oracle 12c SQL, the GROUP BY clause is used to arrange identical data into groups with the GROUP

BY expression followed by the SELECT statement. The SUM() function is then used to calculate the sum

for each grouped record on a specific column, which in this case is the salary column.

Option A is valid because it correctly applies the GROUP BY clause. Both dept_id and join_date are

included in the SELECT statement, which is a requirement when using these columns in conjunction with

the GROUP BY clause. This means that the query will calculate the sum of salaries for each combination of

dept_id and join_date. It adheres to the SQL rule that every item in the SELECT list must be either an

aggregate function or appear in the GROUP BY clause.

Option B is invalid due to a typo in SELECT depe_id and also because it ends with a colon rather than a semicolon.

Option C is invalid because you cannot nest aggregate functions like MAX(AVG(salary)) without a subquery.

Option D is invalid for the same reason as option C, where it tries to nest aggregate functions AVG(MAX(salary)), which is not allowed directly in SQL without a subquery.

For further reference, you can consult the Oracle 12c documentation, which provides comprehensive guidelines on how to use the GROUP BY clause and aggregate functions like SUM(): Oracle Database SQL Language Reference, 12c Release 1 (12.1): GROUP BY Clause Oracle Database SQL Language Reference, 12c Release 1 (12.1): Aggregate Functions

Question:2 (Multi Select) Which three are true about the CREATE TABLE command?

A: It can include the CREATE…INDEX statement for creating an index to enforce the primary key constraint.

B: The owner of the table should have space quota available on the tablespace where the table is defined.

C: It implicitly executes a commit.

D: It implicitly rolls back any pending transactions.

E: A user must have the CREATE ANY TABLE privilege to create tables.

F:The owner of the table must have the UNLIMITED TABLESPACE system privilege.

Correct Answer: B,C and E

Explanation:

A . False – The CREATE TABLE command cannot include a CREATE INDEX statement within it. Indexes to enforce constraints like primary keys are generally created automatically when the constraint is defined, or they must be created separately using the CREATE INDEX command.

B . True – The owner of the table needs to have enough space quota on the tablespace where the table is going to be created, unless they have the UNLIMITED TABLESPACE privilege. This ensures that the database can allocate the necessary space for the table. Oracle Database SQL Language Reference, 12c Release 1 (12.1).

C . True – The CREATE TABLE command implicitly commits the current transaction before it executes. This behavior ensures that table creation does not interfere with transactional consistency. Oracle Database SQL Language Reference, 12c Release 1 (12.1).

D . False – It does not implicitly roll back any pending transactions; rather, it commits them.

E . True – A user must have the CREATE ANY TABLE privilege to create tables in any schema other than their own. To create tables in their own schema, they need the CREATE TABLE privilege. Oracle Database Security Guide, 12c Release 1 (12.1).

F . False – While the UNLIMITED TABLESPACE privilege allows storing data without quota restrictions on any tablespace, it is not a mandatory requirement for a table owner. Owners can create tables as long as they have sufficient quotas on the specific tablespaces.

How Difficult is the 1Z0-071 Exam?

The difficulty of the 1Z0-071 Exam is quite high. The 1Z0-071 test is usually considered moderate. It’s more than memorizing; you require the ability to apply your knowledge of SQL use in the Oracle environment. Candidates with only an understanding of the subject may fail.

To be successful, you must focus on how to apply it. Create a simulation and create your own queries. Explore various joins, functions, and clauses. The more you use them, the more nimble your intuition will get. It is also essential to manage your time effectively. In your exam preparation, you should become familiar with the actual test pace.

Proven Exam Preparation Techniques

A methodical approach to learning can greatly increase your chances of getting a degree.

Thoroughly familiarize yourself with the syllabus: Start by reviewing the official exam topics provided by Oracle. Use this as a guideline to help you plan your study.
Combine Theory and Practice: Don’t just read SQL. Set up Oracle Database (the Express Edition is free) and write code. Test every idea from basic SQL statements to complicated subqueries and DML operations.
Use high-quality study materials: Find reliable resources that cover the syllabus in depth. Official Oracle training can be an excellent option, but it is expensive. This is why the use of third-party preparation materials can be very beneficial.
Exam Practice: The most effective method to prepare for the Exam is replicating the test experience. Practice exam PDF documents and online simulators enable you to identify your weak spots and become familiar with the question format. It will enhance your ability to manage your time.
