Synchronizing data and configurations between the two environments before the switch Synchronizing data and configurations between the blue and green environments is a critical step in a blue-green deployment. This ensures that when the switch is made from the blue to the green environment, the green environment is up-to-date with the latest data and settings, maintaining data consistency and preventing any loss of information or functionality. Option A is incorrect because while performance testing is important, it does not directly ensure data consistency be-tween the two environments. Option C is incorrect as load balancing between the two environments is not typically part of a blue-green deployment strategy, which focuses on one environment being active at a time. Option D is incorrect because simply increasing storage capacity in the green environment does not directly contribute to data consistency for the deployment.

Ensuring the infrastructure can handle different data regulations and compliance requirements across regions This choice addresses the critical need for compliance with varying data regulations in different countries, which is a key factor for an international deployment to re-main viable and legal in the long term. Option A is incorrect as implementing an overly complex architecture initially can lead to unnecessary costs and complexity. Option C is incorrect because choosing the cheapest option may not meet future scalability and compliance needs. Option D is incorrect as it does not consider the dynamic nature of the business and potential future changes.

Single sign-on (SSO) using an external identity provider compatible with their systems Implementing SSO with an external identity provider allows users to seamlessly and securely access both cloud and on-premises systems, providing a unified authentication experience. Option A is incorrect because local authentication in Tableau Cloud does not provide seamless integration with on-premises systems. Option C is incorrect as separate authentication for each system creates a disjointed user experience and increases the risk of security lapses. Option D is incorrect because manual authentication for each session is inefficient and does not provide the security and ease of access that SSO offers.

Choosing a licensing model that aligns with the global distribution of users and adheres to ATR requirements This choice ensures that the licensing model is suitable for the geo-graphical spread of the users, complying with ATR regulations across different regions, which is crucial for a multinational deployment. Option A is incorrect because the cheapest option may not meet the specific needs and compliance requirements of a multinational corporation. Option B is incorrect as ATR compliance is essential for legal and operational reasons, especially in a multinational context. Option D is incorrect because the licensing model should be based on broader organizational needs and compliance, not just the preferences of the IT department.

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.

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.

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.

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.

Implement Tableau Bridge to facilitate scheduled refreshes from the SQL Server database Tableau Bridge allows for the scheduling of data refreshes from on-premises databases like SQL Server to Tableau Cloud, ensuring that the cloud-based dashboards are regularly updated with the latest data. Option A is incorrect as it involves a manual and potentially error-prone process of data export and import. Option C is incorrect because converting data to CSV for manual upload is inefficient and not suitable for regular updates. Option D is incorrect as it introduces unnecessary complexity when Tableau Bridge can directly accomplish this task.
