Question 1

• Simplifying LOD expressions by reducing their complexity can improve performance by decreasing the computational load required to process these expressions.

Option B is incorrect as replacing LOD expressions with table calculations may not improve performance and could change the intended functionality.

Option C is incorrect because increasing the level of detail in LOD expressions usually adds to the computational burden, potentially worsening performance.

Option D is incorrect as using LOD expressions for string comparisons can be highly inefficient and is likely to exacerbate performance issues.

Options :

A : Implement these string manipulation calculations in the underlying database prior to Tableau-s use

B : Replace string manipulations with numerical calculations within Tableau

C : Increase the data refresh rate for the Tableau workbook

D : Split the workbook into multiple smaller workbooks

Answer: A

Question 2

Users are reporting that they cannot access Tableau Server, and initial checks indicate that there are no issues with the Tableau Server itself.

What should be the next step in troubleshooting this problem?

Options :

A : Check the user permissions in Tableau Server to ensure users have the correct access rights

B : Verify the network connectivity and firewall settings to rule out network-related issues

C : Instruct users to clear their browser cache and restart their devices

D : Increase the Tableau Server-s hardware resources to handle more user connections

Answer: B

Question 3

Your organization is using Tableau’s Data Catalog to support its governance strategy.

How can the Data Catalog assist in ensuring that only certified and approved data sources are used for analysis?

Options :

A : Implement Data Catalog to automatically update and certify new data sources

B : Use Data Catalog to provide detailed metadata and certification status of data sources, helping users identify approved sources

C : Configure Data Catalog to delete uncertified data sources automatically

D : Leverage Data Catalog to increase the storage capacity for certified data sources only

Answer: B

Question 4

A client has a pipeline dashboard that takes a long time to load. The dashboard is connected to only one large

data source that is an extract.

It contains two calculated fields:

. TOTAL([Opportunities])

· SUM([Value])

It also contains two filters:

. A Relative Date filter on Created Date, a Date field containing values from 5 years ago until today A Multiple Values (Dropdown) filter on Account Name, a String field containing 1,000 distinct values

A consultant creates a Performance Recording to troubleshoot the issue, and finds out that the longest-running

event is "Executing Query."

Which step should the consultant take to resolve this issue?

Options :

A : Replace the Multiple Values (Dropdown) filter with a Multiple Values (Custom List) filter.

B : Replace the Relative Date filter with a Multiple Values (Dropdown) filter on YEAR([Created Date]).

C : Replace the TOTAL([Opportunities]) calculation with a Grand Total.

D : Replace SUM([Value]) with WINDOW_SUM([Value]).

Answer: B

Question 5

A consultant is evaluating the data lineage in a client’s existing data warehouse to prepare for Tableau integration.

What is a crucial aspect to assess in this evaluation?

Options :

A : The visual appeal of the current data warehouse-s interface

B : The complexity of relationships and transformations within the data warehouse

C : The brand of servers used for the data warehouse

D : The physical location of the data warehouse servers
