Question 1 of 235

The terms "bitmap," "b-tree," and "hash" refer to which type of database structure?

Answer choices
Show answer

Correct answer: C

The terms bitmap, b-tree, and hash are commonly used types of database indices. These indices are data structures that enhance the efficiency of data retrieval operations within a database table, albeit at the cost of additional storage space and the need for extra processing to maintain the indices.

Question 2 of 235

One reason to add an index is to:

Show answer

Correct answer: C

One reason to add an index to a database is to improve the performance of select statements. Indexes speed up the retrieval of rows by using pointers, which significantly reduces the amount of data the database needs to scan, thereby increasing query performance. Decreasing storage space, increasing database security, and improving the performance of insert statements are not directly achievable by adding an index.

Question 3 of 235

You have a table that contains the following data.

This process is referred to as:

Show answer

Correct answer: B

Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. In the given scenario, the original table with ProductID, ProductName, Color1, Color2, and Color3 is divided into two tables: one with ProductID and ProductName, and another with ProductID and Color. This restructuring minimizes redundancy by associating each product with its colors in a separate table, ensuring better organization and consistency. Therefore, the process described is referred to as normalization.

Question 4 of 235

You have a table that contains the following data.

Exam 98-364: Question 4 - Image 1

Which database term is used to describe the relationship between ProductID and ProductCategory?

Answer choices
Show answer

Correct answer: D

In a relational database, when we say that one attribute is functionally dependent on another, it means that for each value of the first attribute, there is exactly one corresponding value of the second attribute. In the given table, each ProductID has exactly one ProductCategory associated with it. Thus, the term that best describes this relationship is 'Functionally dependent'.

Question 5 of 235

Which key uniquely identifies a row in a table?

Answer choices
Show answer

Correct answer: B

A primary key is a field in a table that uniquely identifies each row or record in that table. It must contain unique values and cannot have NULL values. Only one primary key is allowed per table, and it can consist of one or multiple fields.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.
