Detailed Answers
1. What is the difference between Tableau Server and Tableau Online?
Answer: Tableau Server is an on-premise solution that organizations install and manage on their own servers. It offers more control over the infrastructure and integration with internal systems. Tableau Online, on the other hand, is a cloud-based offering hosted by Tableau. It provides the convenience of not having to manage server hardware or software but may have limitations on data connectivity due to being outside the organization's internal network.
Key Points:
- Tableau Server provides more control and requires infrastructure management.
- Tableau Online offers ease of use with less control over the hosting environment.
- Both allow for collaboration, sharing, and security but differ in their setup and maintenance requirements.

2. How do you assign a project-level permission in Tableau?
Answer: To assign project-level permissions in Tableau, you navigate to the specific project on the Tableau Server or Online, click on the "Permissions" tab, and then you can add groups or users and configure their permissions. Permissions can range from Viewer to Project Leader roles, allowing you to control access and capabilities such as viewing, interacting, editing, or managing the project and its contents.
Key Points:
- Navigate to the project and access the "Permissions" tab.
- Add users or groups and set their permission levels.
- Permissions control capabilities within the project.
Example:
// This task is performed through the UI and does not involve C# code.
// No code example is applicable.
3. How can you schedule a data extract refresh in Tableau Server?
Answer: Scheduling a data extract refresh in Tableau Server involves navigating to the workbook or data source, selecting "Schedules," and creating or assigning a refresh schedule. You can specify the frequency, time, and conditions under which the extract should be refreshed to ensure data remains up-to-date.
Key Points:
- Navigate to the workbook or data source and select "Schedules."
- Create or assign an existing schedule.
- Set frequency, time, and conditions for the refresh.
Example:
// Task performed through Tableau Server UI; no direct C# code example.
// No code example is applicable.
4. Describe a strategy for managing permissions in a large organization with multiple teams and projects on Tableau Server.
Answer: Managing permissions in a large organization involves establishing a clear hierarchy and grouping strategy. Start by creating groups that mirror the organization's structure (e.g., departments, teams). Assign roles and permissions at the group level rather than individually to streamline management. Utilize project folders to organize content and set cascading permissions from top-level projects down to subprojects and items, ensuring consistency and reducing administrative overhead.
Key Points:
- Create groups that reflect the organizational structure.
- Assign permissions at the group level for efficiency.
- Use project folders to organize content and set cascading permissions.
Example:
// Managing permissions and creating groups is done through the Tableau Server UI,
// and does not involve direct coding. Strategy and planning are key here.
// No code example is applicable.
