Backgrounder processes ensures efficient handling of high user concurrency and data processing
demands, optimizing performance and responsiveness. Option A is incorrect because a minimal
configuration could lead to performance bottlenecks due to high user demand. Option B is in-correct
as focusing only on Data Server processes neglects the needs for visualization and back-ground tasks.
Option D is incorrect because focusing solely on Backgrounder processes ignores the needs for user
interaction and data querying.
If you encounter an error related to dependency resolution while installing Tableau Server on Linux,
what should be your initial troubleshooting step?
B
Explanation:
Verifying that all required dependencies are installed and up-to-date on the Linux system When
facing a dependency resolution error during the installation of Tableau Server on Linux, the first step
should be to verify that all necessary dependencies are installed and up-to-date. Dependency issues
often arise from missing or outdated packages, and ensuring that the sys-tem meets all pre-
installation requirements is key to resolving these issues. Option A is incorrect be-cause disabling
firewall and antivirus software does not typically address dependency resolution problems. Option C
is incorrect as configuring network settings for unrestricted internet access is not a standard
approach to resolving dependency issues. Option D is incorrect because changing the hostname of
the server is unlikely to resolve dependency-related installation errors.
When recommending an automated deployment method for Tableau Server updates, which
approach is most effective in ensuring minimal disruption and consistent application across a large
organization?
B
Explanation:
Using a network management tool like Microsoft SCCM to automate and standardize the
deployment of updates Utilizing a network management tool such as Microsoft Sys-tem Center
Configuration Manager (SCCM) is the most effective approach for automating and standardizing
Tableau Server updates in a large organization. This method ensures that updates are applied
consistently across all servers, reduces the risk of human error, and minimizes disruption to
operations. Option A is incorrect because manual installation by each server administrator is time-
consuming and prone to inconsistency. Option C is incorrect as email notifications rely on manual
action by administrators, which can lead to delays and inconsistency in updates. Option D is incorrect
because setting up an internal website for downloading updates does not ensure timely or
standardized application across the organization.
In configuring a custom embedded solution for Tableau Server, what is an important consideration
when setting up trusted tickets for user authentication?

embedded solution When setting up trusted tickets for a custom embedded solution in Tableau
Server, it’s crucial to establish a trusted relationship between the Tableau Server and the web server
hosting the embedded solution. This ensures secure and seamless authentication of users accessing
Tableau content through the embedded application. Option A is incorrect because disabling all other
forms of authentication is not necessary and may limit flexibility in access control. Option C is
incorrect as configuring Tableau Server to accept trusted tickets from any domain can pose significant
security risks. Option D is incorrect because trusted tickets should not be the sole method for content
distribution, as they are specifically designed for user authentication in embedded scenarios.
When creating a custom administrative view in Tableau to analyze user activity, which table in the
Tableau repository should you focus on to understand user login patterns?
C
Explanation:
The ‘historical_events’ table to analyze specific events like user logins and log-outs For analyzing user
login patterns in Tableau, the ‘historical_events’ table in the repository is the most relevant. This
table records various events, including user authentication events like logins and logouts, providing
valuable insights into user access patterns and activity on the server. Option A is incorrect because
the ‘datasources’ table focuses on data sources and does not provide information about user login
patterns. Option B is incorrect as the ‘workbooks’ table, while useful for under-standing workbook
usage, does not track user login events. Option D is incorrect because the ‘sites’ table provides
information about sites on the server but does not specifically track user login events.
During the installation of Tableau Server on a Linux system, you encounter a failure with the error
message indicating a permissions issue. What is the first step you should take to resolve this issue?
B
Explanation:
Checking and modifying the file and directory permissions where Tableau Server is being installed
When encountering a permissions issue during the installation of Tableau Server on Linux, the first
and most relevant step is to check and modify the file and directory permissions where Tableau
Server is being installed. Permission issues are common in Linux environments and ensuring that the
Tableau Server installation directory has the correct permissions is essential for a successful
installation. Option A is incorrect because reinstalling the Linux operating system is an excessive
measure for resolving permission issues. Option C is incorrect as increasing hardware resources does
not address permission-related installation failures. Option D is incorrect because changing the file
system is unrelated to permission issues and is not a standard trouble-shooting step for Tableau
Server installation problems.
When configuring extract encryption in Tableau Server, what consideration is important to balance
security with server performance?
B
Explanation:
Ensuring that the server has sufficient processing power and memory to handle the additional load
from encrypting and decrypting extracts When implementing extract encryption in Tableau Server,
it’s important to ensure that the server is equipped with adequate processing power and memory.
Encrypting and decrypting extracts can impose additional load on the server, so it’s crucial to balance
this security feature with the server’s capability to maintain optimal performance. Option A is
incorrect because it creates a mixed environment where some extracts are encrypted and others are
not, leading to inconsistent security practices. Option C is incorrect as disabling extract encryption
during peak times undermines the purpose of having consistent security measures. Option D is
incorrect because the decision to encrypt extracts should not be based on the number of users
accessing them, but rather on a uniform security policy.
You have configured Tableau Server on a Linux system behind a reverse proxy, but users are
experiencing intermittent access issues. What should be the first step in troubleshooting these proxy-
related issues?
B
Explanation:
Verifying the configuration settings of the reverse proxy, including URL rewriting and port forwarding
rules When encountering access issues with Tableau Server configured be-hind a reverse proxy, the
first step should be to verify the proxy’s configuration settings. This includes checking URL rewriting
rules and port forwarding settings to ensure they are correctly routing traffic to and from Tableau
Server. Misconfigurations in these settings can often lead to intermittent access problems. Option A
is incorrect because increasing bandwidth is unlikely to resolve issues specifically related to proxy
configuration. Option C is incorrect as changing the proxy soft-ware provider is not the first
troubleshooting step and may not address the root cause of the issue. Option D is incorrect because
installing a new SSL certificate on Tableau Server, while important for security, does not directly
address proxy configuration issues.
How can the Tableau Services Manager (TSM) be utilized to programmatically manage server
maintenance and configuration changes?
C
Explanation:
Implementing TSM command-line functionality to automate server configuration and maintenance
tasks The Tableau Services Manager (TSM) provides command-line functionality that can be used to
programmatically manage server maintenance and configuration changes. This approach allows for
the automation of various tasks such as adjusting settings, applying up-dates, or managing processes,
which enhances efficiency and consistency in server management. Option A is incorrect because
scheduling regular server restarts is not a typical or recommended practice for server maintenance.
Option B is incorrect as the QUESTIO N NO: emphasizes programmable management, whereas using
the web interface is a manual process. Option D is incorrect because while TSM manages server
updates, it typically requires some level of manual intervention for installation and does not fully
automate the update process.
In the context of Tableau Cloud, what is a key benefit of implementing automated user provisioning
using SCIM?
B
Explanation:
Reducing the administrative overhead associated with manual user account management and
improving security Implementing automated user provisioning using SCIM in Tableau Cloud
significantly reduces the administrative overhead associated with manual user account
management. It also enhances security by ensuring that user account changes in the organization’s
identity management system are automatically and accurately reflected in Tableau Cloud. Option A is
incorrect because SCIM does not eliminate the need for user authentication; it streamlines user
account management. Option C is incorrect as SCIM does not allow users to bypass organizational
identity verification; it ensures user accounts in Tableau Cloud align with these verifications. Option
D is incorrect because the primary role of SCIM is to manage user accounts, not just to track user
activity.
In planning the process topology for a Tableau Server intended for a medium-sized business with
moderate usage patterns, what is the most important consideration for process counts?
C
Explanation:
Tailoring the process count to balance between VizQL, Data Server, and Back-grounder based on
expected usage and demand Customizing the process count to reflect the organization’s specific
usage patterns ensures optimal performance without over-allocating resources, which is crucial for a
medium-sized business. Option A is incorrect because over-allocating processes can be resource-
intensive and unnecessary for moderate usage. Option B is incorrect as it does not account for the
specific needs and usage patterns of the business. Option D is incorrect because it overlooks the
importance of balancing different process types for a well-rounded performance.
When implementing SSL encryption for Tableau Server, what is a critical step to ensure secure
communication?
B
Explanation:
Obtaining and installing a valid SSL certificate from a trusted certificate authority A critical step in
implementing SSL encryption for Tableau Server is to obtain and install a valid SSL certificate from a
trusted certificate authority. This ensures that the communication be-tween the server and clients is
encrypted and secure. Using a certificate from a trusted authority al-so helps in avoiding trust issues
with clients connecting to the server. Option A is incorrect because a self-signed SSL certificate might
not be trusted by all clients and can lead to security warnings. Option C is incorrect as enabling HTTP
does not contribute to SSL encryption; instead, HTTPS should be used. Option D is incorrect because
disabling firewalls can compromise the overall security of the server and is not necessary for SSL
implementation.
When managing a Tableau Server environment on a Linux system, which method is recommended
for deploying automated backup scripts?
B
Explanation:
Using cron jobs to schedule and execute backup scripts at regular intervals On a Linux system, cron
jobs are the recommended method for deploying automated backup scripts for Tableau Server. Cron
allows for the precise scheduling of scripts to run at regular intervals, ensuring consistent and
automated backups without the need for manual initiation. Option A is incorrect be-cause the
Tableau Server web interface does not provide a mechanism for automating server-level scripts like
backups. Option C is incorrect as relying solely on a third-party cloud service for back-ups does not
address the need for local script automation and management. Option D is incorrect because manual
initiation is not efficient for regular maintenance tasks like backups.
To automate the process of refreshing extracts on Tableau Server, which tool or API would be most
effective for scheduling this task?
B
Explanation:
Employing tabcmd to schedule and execute extract refreshes at specified inter-vals Tabcmd is a
highly effective tool for automating extract refreshes on Tableau Server. It can be used to schedule
and execute extract refreshes at regular, specified intervals, ensuring that the data remains up-to-
date without requiring manual intervention each time. Option A is incorrect because webhooks are
typically used for event-driven actions and are less suited for regularly scheduled tasks like extract
refreshes. Option C is incorrect as the Hyper API is more focused on creating and updating extracts,
not on scheduling their refreshes. Option D is incorrect because relying on manual refreshes is time-
consuming and not feasible for consistent data updates in a large-scale environment.
In developing a custom view to monitor the performance of published data sources in Tableau
Server, which part of the Tableau repository schema should be primarily analyzed?
B
Explanation:
The ‘data_connections’ table to gain insights into connections and performance of published data
sources The ‘data_connections’ table in the Tableau repository schema is critical for tracking the
performance of published data sources. It provides detailed information on each connection made to
the data sources, offering insights into how these data sources are being accessed and utilized, which
is crucial for understanding and optimizing their performance. Option A is incorrect because the
‘users’ table, while identifying users, does not provide specific information on data source
performance. Option C is incorrect as the ‘background_tasks’ table focuses on scheduled tasks and
does not offer detailed insights into real-time data source performance. Option D is incorrect
because the ‘server_usage’ table provides a broad overview of server activity but does not offer the
granular details required for monitoring specific data source performance.
