When configuring Tableau Server for use with a load balancer, what is an essential consideration to ensure effective load distribution and user session consistency?
Correct Answer:
B
Enabling sticky sessions on the load balancer to maintain user session consistent-cy Enabling sticky sessions on the load balancer is crucial when integrating with Tableau Server. It ensures that a user’s session is consistently directed to the same server node during their interaction. This is important for maintaining session state and user experience, particularly when interacting with complex dashboards or during data input. Option A is incorrect because while round-robin dis-attribution is a common method, it does not address session consistency on its own. Option C is incorrect as redirecting all write operations to a single node can create a bottleneck and is not a standard practice for load balancing in Tableau Server environments. Option D is incorrect because allocating a separate subnet for the load balancer, while potentially beneficial for network organization, is notdirectly related to load balancing effectiveness for Tableau Server.
In the process of configuring an external gateway for Tableau Server, which of the following is a critical step to ensure secure and efficient communication?
Correct Answer:
A
Setting up a load balancer to distribute traffic evenly across multiple Tableau Server instances Configuring a load balancer is essential in the setup of an external gateway for Tableau Server. It ensures efficient distribution of network traffic and improves the overall performance and reliability of the server by managing the load across multiple instances. Option B is incorrect because bypassing SSL would compromise security, which is not advisable for a secure external gateway setup. Option C is incorrect as direct database access from the gateway is generally not a recommended practice due to security concerns. Option D is incorrect because while implementing firewall rules is important for security, it is not specifically a critical step in configuring an external gateway for Tableau Server.
A large retail company with a high volume of daily Tableau users requires a configuration that optimizes query performance and user experience. Which configuration setting should be prioritized?
Correct Answer:
D
Increase the “vizqlserver.querylimit” value to allow more concurrent queries In-creasing the “vizqlserver. querylimit” value allows more concurrent queries, which is crucial for a company with a high volume of daily users to improve query performance and user experience. Option A is incorrect as decreasing session timeout may disrupt user experience. Option B is incorrect because “backgrounder.querylimit” affects background tasks, not immediate user query performance. Option C is incorrect as reducing cache time might negatively impact performance for frequently accessed data.
In the context of a Tableau Server high-availability setup, what is a crucial consideration when con-figuring a coordination ensemble?
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 co-ordination ensemble nodes do not typically require significantly more storage than other nodes; their primary role is coordination, not data storage.
When installing Tableau Server on a Windows system, which step is essential to ensure a successful installation using the Installation Wizard?
Correct Answer:
B
Running the Installation Wizard as an administrator to ensure sufficient privileges for setup When installing Tableau Server on Windows, it is crucial to run the Installation Wizard as an administrator. This ensures that the installer has the necessary privileges to access system resources and configure settings required for the successful installation of Tableau Server. Option A is incorrect because while antivirus or firewall software can sometimes interfere with installations, it’s not recommended to disable all security software as a first step. Option C is incorrect as automatically updating system drivers during the installation is not a standard requirement for installing Tableau Server. Option D is incorrect because setting up a dedicated virtual machine is not a requirement for installing Tableau Server, though it can be an option based on organizationalpolicies.
