Tableau TCA-C01 Practice Test - Questions Answers, Page 4

Implement a geographically dispersed disaster recovery setup for the Tableau deployment This strategy ensures that in case of a system failure at one location, the data and services can be quickly restored from another geographical location, which is crucial for maintaining continuous healthcare services. Option A is incorrect because avoiding disaster recovery infrastructure exposes the provider to significant risks of data loss and service disruption. Option B is incorrect as it does not provide a safeguard against disasters that could affect the single location. Option D is incorrect because manual processes are not efficient or reliable enough for the critical data and operational needs of a healthcare provider.

Simplifying the calculated fields and reducing the number of filters and parameters in the workbook When facing slow loading times with a complex Tableau workbook, the first step should be to review and simplify the workbook's design. This includes optimizing calculated fields, reducing the number of filters and parameters, and streamlining the visualizations. These actions can significantly improve performance by reducing the complexity and processing requirements of the dashboards. Option A is incorrect because increasing hardware resources might not resolve issues inherent to the workbook's design. Option C is incorrect as splitting the workbook into smaller workbooks might not address the root cause of the performance issue. Option D is in-correct because network speed, while important, is less likely to be the primary cause of performance issues for a complex workbook.

Using a physical medium to transfer the Tableau Server installation files to the environment In an air-gapped environment, where there is no direct internet connection, using a physical medium (like a USB drive or external hard disk) to transfer the Tableau Server installation files is essential. This method ensures that the necessary software can be securely introduced into the isolated environment for installation. Option A is incorrect because direct internet access is typically not possible or allowed in an air-gapped environment. Option C is incorrect as a proxy server implies some level of external network access, which is not available in an air-gapped setup. Option D is incorrect because implementing a VPN is not feasible in a truly air-gapped environment where no external network connections are allowed.

To provide seamless user experience during upgrades or maintenance The primary purpose of maintaining two identical environments in a blue-green deployment is to ensure a seamless user experience during upgrades or maintenance. This approach allows for one environment (blue) to be active while the other (green) is updated or maintained. Users are then switched over to the updated environment with minimal disruption. Option A is incorrect because using one environment for development and the other for production is not the primary goal of blue-green deployment, which focuses on seamless transitions during updates. Option B is incorrect as A/B testing is not the main objective of blue-green deployment, which is more about minimizing downtime and ensuring service continuity. Option D is incorrect because dividing the workload between servers is not the fundamental purpose of this strategy; rather, it's about having a ready-to-go, updated environment.

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.

The CPU and memory utilization of the Tableau Server during peak usage times When performing a resource analysis to identify performance bottlenecks, it is essential to examine the CPU and memory utilization of Tableau Server, especially during peak usage times. High utilization of these resources can indicate that the server is under strain and may be the cause of performance issues. Understanding these metrics helps in pinpointing the need for resource scaling or optimization. Option A is incorrect because while disk space used by data extracts is important, it does not directly indicate CPU and memory bottlenecks. Option C is incorrect as the number of user li-censes utilized does not directly affect the server's resource utilization. Option D is incorrect be-cause while software version and compatibility are important, they are not directly related to real-time resource utilization and performance bottlenecks.

Establish a multi-node Tableau Server cluster with load balancing and failover capabilities This approach ensures high availability and robust disaster recovery by distributing the load across multiple nodes and providing failover capabilities in case of a node failure, which is critical for a financial institution's continuous operation. Option A is incorrect because a single node does not provide high availability or disaster recovery capabilities. Option C is incorrect as regular data backups are important but not sufficient for high availability and immediate failover needs. Option D is incorrect because relying solely on a cloud-based service without on-premises disaster recovery plans may not meet the specific compliance and control requirements of a global financial institution.

Implementing OAuth for secure, token-based authentication for external applications accessing the Metadata API Implementing OAuth for secure, token-based authentication is crucial when allowing external applications to access the Metadata API. This ensures that only authorized applications can access the API, enhancing security by providing controlled access based on authenticated tokens. Option A is incorrect because unrestricted access can lead to security vulnerabilities and performance issues. Option B is incorrect as real-time updates are more related to the functionality of the Metadata API rather than its configuration for external applications. Option D is incorrect because direct database access is not a standard or safe practice for external applications, especially in the context of API access.
