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

  1. To use one for development and the other for production
  2. To enable A/B testing with different user groups
  3. To provide seamless user experience during upgrades or maintenance
  4. 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.



When optimizing caching for Tableau Server to improve dashboard performance, which setting is most effective to adjust?

  1. Setting the cache to refresh every time a view is loaded to ensure the most up-to-date data is always used
  2. Configuring the cache to be cleared at a regular, scheduled interval that aligns with the data refresh schedule
  3. Disabling caching entirely to force real-time queries for all dashboard views
  4. Increasing the server's RAM to enhance its overall caching capability

Answer(s): B

Explanation:

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.



When conducting a resource analysis to identify performance bottlenecks in Tableau Server, which metric is most critical to examine?

  1. The total disk space used by Tableau Server data extracts
  2. The CPU and memory utilization of the Tableau Server during peak usage times
  3. The number of user licenses utilized on the Tableau Server
  4. The version of the Tableau Server software and its compatibility with the operating system

Answer(s): B

Explanation:

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.



A global financial institution requires a Tableau deployment that ensures continuous operation and data protection.
What should be the primary focus in their high availability and disaster recovery planning?

  1. Implement a single Tableau Server node to simplify management
  2. Establish a multi-node Tableau Server cluster with load balancing and failover capabilities
  3. Rely solely on regular data backups without additional infrastructure considerations
  4. Use a cloud-based Tableau service without any on-premises disaster recovery plans

Answer(s): B

Explanation:

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.



In the context of Tableau Server, what is an important consideration when configuring access to the Metadata API for external applications?

  1. Allowing unrestricted access to the Metadata API from any external application
  2. Configuring the Metadata API to provide real-time updates to external applications
  3. Implementing OAuth for secure, token-based authentication for external applications accessing the Metadata API
  4. Ensuring external applications have direct database access for synchronized metadata retrieval

Answer(s): C

Explanation:

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.

answer to this question "what administrative safeguards should be implemented to protect the collected data while in use by manasa and her product management team? " it should be (c) for the following reasons: this administrative safeguard involves controlling access to collected data by ensuring that only individuals who need the data for their job responsibilities have access to it. this helps minimize the risk of unauthorized access and potential misuse of sensitive information. while other options such as (a) documenting data flows and (b) conducting a privacy impact assessment (pia) are important steps in data protection, implementing a "need to know" access policy directly addresses the issue of protecting data while in use by limiting access to those who require it for legitimate purposes. (d) is not directly related to safeguarding data during use; it focuses on data transfers and location.

password lockout being the correct answer for question 37 does not make sense. it should be geofencing.

q. 289 - the correct answer should be b not d, since the question asks for the most secure way to provide access to a s3 bucket (a single one), and by principle of the least privilege you should not be giving access to all buckets.
