Question #31
After reviewing observability data, you find that Tableau Server’s data extract refreshes are significantly impacting performance during business hours.
What architectural change should be made to address this issue?
- A . Moving all data extracts to live connections to avoid refreshes
- B . Scheduling extract refreshes during off-peak hours to minimize impact on performance
- C . Completely disabling extract refreshes to enhance server performance
- D . Upgrading the server’s CPU to speed up extract refreshes
Correct Answer: B
B
Explanation:
Correct Answer
B. Scheduling extract refreshes during off-peak hours to minimize impact on performance. An effective architectural adjustment in response to performance impacts from data extract refreshes is to reschedule these refreshes to off-peak hours. This change minimizes the performance impact during business hours when server demand is typically higher, thereby maintaining better overall server performance.
Option A is incorrect because switching all data extracts to live connections might not be feasible or desirable for all data sources and can have its own performance implications.
Option C is incorrect as completely disabling extract refreshes could compromise data freshness and functionality for users.
Option D is incorrect because while upgrading the CPU may improve performance, it does not address the core issue of extract refreshes impacting server use during peak times.

Question #33
In a multi-node Tableau Server environment, you are experiencing intermittent database connectivity issues.
What should be the first step in troubleshooting this problem?
- A . Increasing the number of worker nodes in the Tableau Server environment to enhance overall connectivity
- B . Checking the network configuration and firewalls between the Tableau Server nodes and the
database server for any connectivity barriers - C . Upgrading the database server’s hardware to improve its ability to handle connections
- D . Changing the database server to a different platform that is known for more stable connectivity
Correct Answer: B
B
Explanation:
Correct Answer
B. Checking the network configuration and firewalls between the Tableau Server nodes and the database server for any connectivity barriers. The first step in troubleshooting intermittent database connectivity issues in a multi-node Tableau Server environment is to check the network configuration and firewall settings.

Question #34
You are configuring Tableau Server on a Linux system and find that the server is not accessible from client machines.
What should be your initial step to resolve this issue?
- A . Increasing the bandwidth allocation to the Linux server
- B . Checking the DNS settings and ensuring the Linux server is correctly resolving hostnames
- C . Assigning a static IP address to each client machine
- D . Changing the network mode on the Linux server from public to private
Correct Answer: B
B
Explanation:
Correct Answer
B. Checking the DNS settings and ensuring the Linux server is correctly resolving hostnames. When Tableau Server on a Linux system is not accessible from client machines, the initial step should be to check the DNS settings. Ensuring that the Linux server can correctly resolve hostnames is important for network accessibility. Incorrect DNS settings or issues with hostname resolution can prevent clients from accessing the server.
Option A is incorrect because bandwidth allocation is typically not related to issues of server accessibility in a local network setting.
Option C is incorrect as assigning static IP addresses to client machines does not address the accessibility of the server itself.
Option D is incorrect because changing the network mode from public to private on the Linux server does not directly address accessibility or DNS resolution issues.

Question #35
In the context of SSL encryption for Tableau Server, what factor is important to consider to maintain the effectiveness of the SSL implementation?
- A . Regularly updating the Tableau Server software to the latest version
- B . Ensuring the SSL certificate covers all domain names and subdomains used by Tableau Server
- C . Increasing the bandwidth capacity of the network to accommodate SSL traffic
- D . Configuring all user accounts in Tableau Server to require SSL for authentication
Correct Answer: B
B
Explanation:
Correct Answer
B. Ensuring the SSL certificate covers all domain names and subdomains used by Tableau Server When implementing SSL encryption in Tableau Server, it is important to ensure that the SSL certificate covers all domain names and subdomains used by the server. This ensures that SSL protection is applied consistently across the entire server environment, preventing security gaps that might occur if some parts of the domain are not covered.
Option A is incorrect because while updating Tableau Server is important for overall security and functionality, it is not specific to maintaining the effectiveness of SSL implementation.
Option C is incorrect as increasing bandwidth capacity is generally not required solely due to SSL traffic.
Option D is incorrect because configuring user accounts to require SSL for authentication, while a good security practice, is not directly related to the effectiveness of the SSL certificate coverage on the server.

Question #37
If a performance recording indicates that query response times from external databases are the primary bottleneck in Tableau Server, what should be the first course of action?
- A . Upgrading the external database servers for faster processing
- B . Reviewing and optimizing the database queries used in Tableau workbooks for efficiency
- C . Implementing caching mechanisms in Tableau Server to reduce the reliance on database queries
- D . Restricting the size of data extracts to lessen the load on the external databases
Correct Answer: B
B
Explanation:
Correct Answer
B. Reviewing and optimizing the database queries used in Tableau workbooks for efficiency. The first course of action when dealing with slow query response times from external databases, as indicated by a performance recording, should be to review and optimize the database queries used in Tableau workbooks. Optimizing queries can include simplifying them, reducing the amount of data queried, or improving the structure of the queries. This directly addresses the inefficiencies in the queries, potentially improving response times without the need for major infrastructure changes.
Option A is incorrect because upgrading external database servers is a more resource-intensive solution and should be considered only if query optimization is not sufficient.
Option C is incorrect as implementing caching mechanisms might alleviate some issues but does not address the root cause of slow query performance.
Option D is incorrect because restricting the size of data extracts does not necessarily improve the efficiency of the queries themselves.

Question #39
During the installation of Tableau Server on Linux, which action is crucial to ensure proper system group and file system permissions are set?
- A . Assigning the Tableau Server user to the root group to ensure full system access
- B . Creating a dedicated Tableau user and group, and setting appropriate ownership and permissions on the Tableau directories
- C . Configuring all users on the Linux system to have administrative privileges for the duration of the Tableau Server installation
- D . Disabling the Linux system’s firewall to prevent it from interfering with file permissions
Correct Answer: B
B
Explanation:
Correct Answer
B. Creating a dedicated Tableau user and group, and setting appropriate ownership and permissions on the Tableau directories. For a successful Tableau Server installation on Linux, it’s crucial to create a dedicated Tableau user and group. Setting appropriate ownership and permissions on the Tableau directories ensures that Tableau Server has the necessary access rights to operate correctly while maintaining the security and integrity of the system.
Option A is incorrect because assigning the Tableau Server user to the root group poses significant security risks and is not recommended.
Option C is incorrect as giving all users administrative privileges is unnecessary for Tableau Server installation and could compromise system security.
Option D is incorrect because disabling the firewall does not affect file system permissions and is not a recommended practice during installation.
