In configuring web data connectors (WDCs) on Tableau Server, what step is essential for maintaining data accuracy and security?
- A . Enforcing that all WDCs must be hosted on the same server as Tableau Server
- B . Regularly updating WDCs to the latest version available, irrespective of testing and compatibility checks
- C . Ensuring that WDCs are securely accessing data sources and handling data transfer securely and efficiently
- D . Limiting WDC usage to only internally developed connectors and prohibiting any third-party
connectors
Correct Answer: C
C
Explanation:
Correct Answer
C. Ensuring that WDCs are securely accessing data sources and handling data transfer securely and efficiently When configuring web data connectors on Tableau Server, it is essential to ensure that these connectors access data sources securely and handle data transfer efficiently. This involves verifying the security of the data source connections and ensuring that data handling by the WDCs adheres to best practices for data security and integrity.
Option A is incorrect because it is not necessary for all WDCs to be hosted on the same server as Tableau Server.
Option B is incorrect as updating WDCs without proper testing and compatibility checks can lead to issues with data accuracy or security.
Option D is incorrect because while internal connectors may offer certain security assurances, prohibiting all third-party connectors can unnecessarily limit functionality and innovation.

In the context of deploying Tableau Server with an external repository, what is a key factor to consider for ensuring optimal performance of the server?
- A . The external repository must be located on the same physical server as the Tableau Server
- B . The external repository should be configured with a higher storage capacity than the Tableau Server
- C . Synchronization frequency between the Tableau Server and the external repository should be minimized
- D . Ensure the network connection between Tableau Server and the external repository has low latency
Correct Answer: D
D
Explanation:
Correct Answer
D. Ensure the network connection between Tableau Server and the external repository has low latency A low-latency network connection is vital for optimal performance when Tableau Server is integrated with an external repository. This facilitates faster data retrieval and improves overall responsiveness, which is crucial for efficient data analysis and reporting.
Option A is incorrect because it is not necessary for the external repository to be on the same physical server; what matters more is the network connection quality.
Option B is incorrect as having higher storage capacity does not directly impact the performance of the server in relation to the external repository.
Option C is incorrect because synchronization frequency is typically managed to balance performance and data freshness, and minimizing it is not always the optimal approach.

Question #125
In a situation where Tableau Server on a Windows system is not starting properly, which logs should be prioritized to diagnose startup issues?
- A . The antivirus logs to check for any interference with Tableau Server files
- B . The Tableau Server log files, especially the "tabadmin.log" and "tabsvc.log" files
- C . The SQL Server logs if Tableau Server is using SQL Server as its repository
- D . The user access logs to determine if there were any unauthorized access attempts
Correct Answer: B
B
Explanation:
Correct Answer
B. The Tableau Server log files, especially the “tabadmin.log” and “tabsvc.log” files When facing startup issues with Tableau Server on a Windows system, the Tableau Server log files, particularly “tabadmin.log” and “tabsvc.log,” should be reviewed first. These logs can provide detailed insights into the startup process and highlight any errors or issues that are preventing the server from starting correctly.
Option A is incorrect because antivirus logs, while useful for checking interference with program files, are not the primary source for diagnosing startup issues with Tableau Server.
Option C is incorrect as SQL Server logs are more relevant for database-related issues and may not provide specific details on Tableau Server startup problems.
Option D is incorrect because user access logs generally do not contain information relevant to system startup issues.

Question #126
In the context of a Tableau Server high-availability setup, what is a crucial consideration when configuring a coordination ensemble?
- A . The ensemble should be configured on a single node to centralize coordination control
- B . Ensemble nodes should be distributed across different physical locations for geographical redundancy
- C . It’s important to configure an odd number of ensemble nodes to prevent split-brain scenarios
- D . Coordination ensemble nodes require significantly more storage than other nodes in the cluster
Correct Answer: C
C
Explanation:
Correct Answer
C. It’s important to configure an odd number of ensemble nodes to prevent split-brain scenarios Configuring an odd number of nodes in the coordination ensemble is crucial to avoid split-brain scenarios where two halves of a cluster might operate independently due to a network partition. An odd number ensures that a clear majority can be established, which is necessary for consensus and coordination.
Option A is incorrect because centralizing coordination control on a single node can be a single point of failure and is not recommended for high availability.
Option B is incorrect as while geographical redundancy is good, it’s not specifically related to the configuration of the coordination ensemble within a Tableau Server cluster.
Option D is incorrect because coordination ensemble nodes do not typically require significantly more storage than other nodes; their primary role is coordination, not data storage.

Question #129
When optimizing caching for Tableau Server to improve dashboard performance, which setting is most effective to adjust?
- A . Setting the cache to refresh every time a view is loaded to ensure the most up-to-date data is always used
- B . Configuring the cache to be cleared at a regular, scheduled interval that aligns with the data refresh schedule
- C . Disabling caching entirely to force real-time queries for all dashboard views
- D . Increasing the server’s RAM to enhance its overall caching capability
Correct Answer: B
B
Explanation:
Correct Answer
B. Configuring the cache to be cleared at a regular, scheduled interval that aligns with the data refresh schedule Configuring Tableau Server’s cache to clear at regular intervals that align with the data refresh schedule can effectively balance performance with data freshness. This approach ensures that users receive relatively recent data while still benefiting from the performance improvements that caching provides.
Option A is incorrect because refreshing the cache every time a view is loaded can negate the performance benefits of caching and may lead to unnecessary load on the server.
Option C is incorrect as disabling caching entirely would prevent Tableau Server from leveraging cached data for faster performance.
Option D is incorrect because while increasing RAM can enhance a server’s capacity, it does not directly optimize caching strategies related to dashboard performance.
