Question #51
In creating an appropriate test plan for load testing a Tableau Server deployment, which aspect is crucial to include for a comprehensive evaluation?
- A . Testing exclusively with the largest and most complex dashboards to evaluate the server’s maximum capacity
- B . Including a mix of different user activities, such as viewing dashboards, publishing workbooks, and performing data refreshes
- C . Focusing solely on the data extract refresh times to determine the overall server performance
- D . Limiting the test to a small, controlled group of users to maintain consistency in the testing process
Correct Answer: B
B
Explanation:
Correct Answer
B. Including a mix of different user activities, such as viewing dashboards, publishing workbooks, and performing data refreshes. For a comprehensive evaluation in a load testing plan for Tableau Server, it’s essential to include a variety of user activities. This approach ensures that the testing covers a broad range of interactions, such as viewing dashboards, publishing workbooks, and performing data refreshes, thereby providing a more holistic view of the server’s performance under different types of load.
Option A is incorrect because testing exclusively with the largest and most complex dashboards does not represent the typical range of user activities.
Option C is incorrect as focusing solely on data extract refresh times overlooks other crucial aspects of server performance.
Option D is incorrect because limiting the test to a small user group does not adequately simulate the diverse and concurrent usage patterns seen in a production environment.

Question #52
When configuring trusted authentication for Tableau Server, which step is essential to ensure that the server securely accepts requests from a trusted third-party application?
- A . Setting up a VPN tunnel between Tableau Server and the third-party application
- B . Adding the third-party application’s server IP address to the list of trusted hosts in Tableau Server
- C . Configuring all users in Tableau Server to have default administrative privileges
- D . Enabling cross-origin resource sharing (CORS) on Tableau Server for all domains
Correct Answer: B
B
Explanation:
Correct Answer
B. Adding the third-party application’s server IP address to the list of trusted hosts in Tableau Server. For trusted authentication to function correctly, it is crucial to add the third-party application’s server IP address to Tableau Server’s list of trusted hosts. This step ensures that Tableau Server recognizes and accepts authentication requests from this specific application, enhancing security by limiting access to known, trusted sources.
Option A is incorrect because setting up a VPN tunnel is not a standard requirement for configuring trusted authentication in Tableau Server.
Option C is incorrect as configuring default administrative privileges for all users is unrelated to trusted authentication and poses a security risk.
Option D is incorrect because enabling CORS for all domains is not directly related to the configuration of trusted authentication and could introduce security vulnerabilities.

Question #55
A large multinational corporation plans to deploy Tableau across various departments with diverse data access needs. The IT team needs to determine the optimal role distribution for users.
Which of the following approaches best meets these requirements?
- A . Assign all users the "Viewer" role to maintain data security and control
- B . Provide "Creator" roles to department heads and "Explorer" roles to their team members
- C . Implement a uniform "Explorer" role for all users to simplify management
- D . Tailor user roles based on specific department needs and data access levels
Correct Answer: D
D
Explanation:
Correct Answer
D. Tailor user roles based on specific department needs and data access levels. This approach ensures that each department gets the access they need while maintaining security and efficiency. It recognizes the varying requirements across departments and aligns role assignments accordingly.

Question #57
When configuring the Metadata API in Tableau Server, which step is crucial for ensuring the API’s effective performance and security?
- A . Regularly changing the API key to prevent unauthorized access
- B . Setting up rate limits to control the number of requests to the Metadata API
- C . Configuring the Metadata API to run on a separate server from the main Tableau Server
- D . Encrypting all Metadata API responses with an additional encryption layer
Correct Answer: B
B
Explanation:
Correct Answer
B. Setting up rate limits to control the number of requests to the Metadata API Setting up rate limits for the Metadata API is essential to manage the load on the Tableau Server and to prevent abuse of the API. Rate limiting helps to maintain the server’s performance and stability by controlling the number and frequency of requests processed by the Metadata API.
Option A is incorrect because regularly changing the API key, while a good security practice, is not specifically related to the performance and security of the Metadata API in operation.
Option C is incorrect as running the Metadata API on a separate server is not a standard requirement and does not directly contribute to its effective performance.
Option D is incorrect because adding an extra encryption layer to Metadata API responses is generally unnecessary and can add undue complexity, as the API should already operate under secure protocols.

What is the most effective troubleshooting step?
- A . Rebuilding all affected dashboards from scratch.
- B . Checking the data source connections and refresh schedules for the affected dashboards.
- C . Immediately transitioning back to an on-premises Tableau Server.
- D . Limiting user access to the dashboards to reduce system load.
Correct Answer: B
B
Explanation:
Correct Answer
B. Checking the data source connections and refresh schedules for the affected dashboards This step directly addresses the potential issue by ensuring that the dashboards are properly connected to the data sources and that the refresh schedules are correctly configured.
Option A is incorrect because rebuilding dashboards is time-consuming and may not address the underlying issue with data refresh.
