QUESTION: 33

A healthcare provider with multiple locations is implementing Tableau and needs to ensure data availability in the event of a system failure.
What is the most appropriate strategy for their needs?

Avoid investing in disaster recovery infrastructure to reduce costs
Focus on high availability within a single location without offsite disaster recovery
Implement a geographically dispersed disaster recovery setup for the Tableau deployment
Utilize manual processes for disaster recovery to maintain data control

Answer(s): C

Explanation:

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.

QUESTION: 34

A Tableau workbook with multiple complex dashboards is experiencing slow loading times.
What is the first step in troubleshooting this workbook performance issue?

Increasing the server's hardware resources, such as RAM and CPU capacity
Simplifying the calculated fields and reducing the number of filters and parameters in the workbook
Splitting the workbook into several smaller workbooks to distribute the load
Checking the network speed between the Tableau Server and the client machines

Answer(s): B

Explanation:

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.

QUESTION: 35

When installing Tableau Server in an air-gapped environment, which of the following steps is essential to ensure a successful installation and operation?

Enabling direct internet access from the Tableau Server for software updates
Using a physical medium to transfer the Tableau Server installation files to the environment
Configuring Tableau Server to use a proxy server for all external communications
Implementing a virtual private network (VPN) to allow remote access to the Tableau Server

Answer(s): B

Explanation:

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.

QUESTION: 36

In a blue-green deployment scenario for Tableau Server, what is the primary purpose of maintaining two identical environments?

To use one for development and the other for production
To enable A/B testing with different user groups
To provide seamless user experience during upgrades or maintenance
To divide the workload evenly between two servers

Answer(s): C

Explanation:

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.
