Tableau TDS-C01 Exam Questions

Question 6 of 114

What are two characteristics of relationships? (Choose two.)

A.

Relationships will query every table in a data model regardless of whether the fields are in the visualization.

B.

Relationships will query only the tables and fields needed to create a visualization.

C.

Relationships are only supported when using extracts.

D.

Relationships are aware automatically of the native level of detail of logical tables.

Correct Answer: BD

Relationships in data models will query only the tables and fields needed to create a visualization. This ensures efficiency in data retrieval and reduces unnecessary processing. Additionally, relationships are aware automatically of the native level of detail of logical tables, allowing for accurate and optimized data representation based on the inherent granularity of the data.

Question 7 of 114

What are two examples of a date value? (Choose two.)

A.

January 1, 1995

B.

December

C.

Wednesday

D.

2020-05-01

Correct Answer: AD

Examples of date values are specific instances in time that usually include a day, month, and year. January 1, 1995 is a specific date presented in a common written format, while 2020-05-01 is a specific date in ISO format. December and Wednesday represent a month and a day of the week, respectively, and are not complete date values.

Question 8 of 114

What are three reasons to use joins instead of relationships? (Choose three.)

A.

You need to use a specific join type.

B.

You need to create an extract that will have multiple tables.

C.

You need to use row-level security.

D.

You need to use a data model that supports shared dimensions.

E.

You need to connect to multiple databases.

Correct Answer: ACD

The three reasons to use joins instead of relationships are: when you need to use a specific join type, when you need to use row-level security, and when you need to use a data model that supports shared dimensions. Using a specific join type allows for more control over how data from different tables is combined. Row-level security is often implemented via joins to restrict access to specific rows of data. Data models that support shared dimensions can be more effectively managed with joins.

Question 9 of 114

What are three benefits of using an extract as compared to a live connection to a data source? (Choose three.)

A.

A live connection to a data source provides the best performance for data connections.

B.

Calculated fields perform better in workbooks connected to extracts than in workbooks with live connections to a data source.

C.

Extracts are stored in memory (RAM), resulting in faster query performance as compared with live data connections.

D.

An extract reduces the amount of data stored on a client computer as compared to a live data connection.

E.

A live connection to a data source can be slow due to network and user traffic, whereas a connection to an extract improves performance.

Correct Answer: BCE

Using an extract offers several benefits over a live connection to a data source. Calculated fields tend to perform better with extracts because Tableau can pre-process and optimize the data for quicker query performance. Extracts are stored in memory (RAM), leading to faster query performance as compared to live connections which rely on querying data over a network. Additionally, live connections can face performance issues due to network and user traffic, whereas extracts can mitigate these issues by operating locally.

Question 10 of 114

How can you access options to apply bold formatting to an axis in the view?

A.

Select Text on the Marks card.

B.

Select Field Labels on the Format menu.

C.

Right-click on the Field and select Format.

D.

Right-click on the axis.

Correct Answer: D

To apply bold formatting to an axis in the view, right-click on the axis itself. This action will provide formatting options specific to the axis, including the ability to change the font style to bold.
