When configuring the Metadata API in Tableau Server, which step is crucial for ensuring the API's effective performance and security?

  1. Regularly changing the API key to prevent unauthorized access
  2. Setting up rate limits to control the number of requests to the Metadata API
  3. Configuring the Metadata API to run on a separate server from the main Tableau Server
  4. Encrypting all Metadata API responses with an additional encryption layer

Answer(s): B

Explanation:

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.



In a scenario where Tableau Server is experiencing slow response times, what aspect should be analyzed first in a latency analysis to identify the root cause?

  1. The network speed and bandwidth between client machines and the Tableau Server
  2. The frequency of scheduled extract refreshes on the Tableau Server
  3. The response time of queries sent from Tableau Server to connected data sources
  4. The time taken for administrative tasks, such as user creation and permission assignment

Answer(s): C

Explanation:

The response time of queries sent from Tableau Server to connected data sources In a latency analysis aimed at identifying the root cause of slow response times in Tableau Server, it is important to first analyze the response time of queries sent from the server to its connected data sources. Long query response times can be a primary factor contributing to overall server latency, affecting the speed at which visualizations and dashboards load. Option A is incorrect because while network speed and bandwidth are important, they are more related to the infrastructure rather than specific to Tableau Server's internal processing. Option B is incorrect as the frequency of extract refreshes, while impactful on performance, is not the first aspect to assess in a latency analysis. Option D is incorrect because the time taken for administrative tasks is generally un-related to the response time issues experienced by end-users in accessing dashboards and reports.



In a Tableau Server deployment using a load balancer, what configuration is necessary to ensure SSL

(Secure Socket Layer) encryption is effectively implemented?

  1. SSL termination must be configured at the load balancer level
  2. SSL certificates should be installed on each individual Tableau Server node
  3. The load balancer should be configured to bypass SSL for internal network traffic
  4. A single SSL certificate must be shared between the load balancer and the Tableau Server

Answer(s): A

Explanation:

SSL termination must be configured at the load balancer level Configuring SSL termination at the load balancer level is essential in a Tableau Server deployment. This setup enables the load balancer to decrypt incoming SSL traffic and then distribute the requests across the server nodes. This approach simplifies SSL management and ensures secure communication between clients and the load balancer. Option B is incorrect because installing SSL certificates on each node is redundant and less efficient when SSL termination is handled at the load balancer. Option C is in-correct as bypassing SSL for internal traffic can compromise security, particularly for sensitive data. Option D is incorrect because sharing a single SSL certificate between the load balancer and Tableau Server is not a standard or recommended practice; the focus should be on SSL termination at the load balancer.



A company using Tableau Cloud experiences intermittent performance issues, particularly during peak usage times.
What should be the first step in troubleshooting these issues?

  1. Increasing the number of Tableau Cloud instances without analyzing usage patterns
  2. Analyzing user access patterns and resource utilization to identify bottlenecks
  3. Immediately upgrading the company's internet connection
  4. Reducing the number of dashboards available to users to decrease load

Answer(s): B

Explanation:

Analyzing user access patterns and resource utilization to identify bottlenecks This approach involves a methodical analysis to understand the root cause of performance issues, focusing on how and when the resources are being utilized. Option A is incorrect because increasing cloud instances without understanding the issue may not resolve the problem and could lead to un-necessary costs. Option C is incorrect as upgrading the internet connection might not address the underlying issue within Tableau Cloud's configuration. Option D is incorrect because reducing the number of dashboards does not directly address the issue of performance during peak times and might hinder business operations.
