Ensuring that the new SSL certificate is renewed and installed before the expiration of the current certificate When renewing an SSL certificate for Tableau Server, it is important to ensure that the new certificate is renewed and installed before the current one expires. This continuity prevents any interruptions in SSL encryption and maintains secure communications without any downtime or security warnings due to an expired certificate. Option A is incorrect because the new certificate does not necessarily need to have the exact same specifications; updates or changes might be beneficial. Option C is incorrect as switching SSL protocol versions during renewal should be done based on security needs and compatibility, not as a routine process. Option D is incorrect because disabling SSL encryption, even temporarily, can expose the server to security risks.

Perform a thorough audit of current dashboards and data sources for compatibility with Tableau Cloud Conducting an audit of dashboards and data sources ensures compatibility with Tableau Cloud, which is crucial for a smooth migration without data loss or functionality issues. Option A is incorrect because migrating everything at once can overwhelm the system and lead to significant disruptions. Option C is incorrect as prioritizing the least used dashboards might not address the migration challenges of more critical dashboards and data. Option D is incorrect be-cause discontinuing Tableau Server immediately can disrupt business operations and does not allow for a phased and controlled transition.

Use a dedicated service account with restricted permissions for repository access Utilizing a dedicated service account with restricted permissions is crucial for maintaining security while accessing an external repository. This ensures that Tableau Server interacts with the repository in a controlled manner, reducing the risk of unauthorized access or data breaches. Option A is incorrect because allowing anonymous access compromises security and is not recommended for external repositories. Option B is incorrect as a direct VPN connection, while secure, is not a necessary step for configuring an external repository in Tableau Server. Option C is incorrect because repository partitioning based on user roles and permissions is not a standard feature or requirement for Tableau Server’s external repository configuration.

Increase the “vizqlserver.querylimit” value to allow more concurrent queries In-creasing the “vizqlserver.querylimit” value allows more concurrent queries, which is crucial for a company with a high volume of daily users to improve query performance and user experience. Option A is incorrect as decreasing session timeout may disrupt user experience. Option B is incorrect because “backgrounder.querylimit” affects background tasks, not immediate user query performance. Option C is incorrect as reducing cache time might negatively impact performance for frequently accessed data.

The expiration dates of the SSL certificates on both the client and server A common issue in Mutual SSL authentication is the expiration of SSL certificates. Checking the expiration dates of the certificates on both the client and server sides is crucial, as expired certificates will prevent successful authentication. Regular monitoring and timely renewal of certificates are key to maintaining uninterrupted Mutual SSL connections. Option A is incorrect because while browser compatibility is important, it is not a common cause of Mutual SSL issues. Option C is incorrect as network bandwidth, while important for overall connectivity, does not directly impact Mutual SSL authentication. Option D is incorrect because the version of Tableau Server is generally not related to specific SSL protocol versions for Mutual SSL authentication.

Integrating SCIM with the organization’s identity provider to automate the process of creating, updating, and deactivating user accounts in Tableau Cloud Utilizing SCIM in conjunction with the organization’s identity provider allows for the automation of user account management in Tableau Cloud. This integration can automatically create, update, and deactivate user accounts based on changes in the organization’s identity management system, ensuring that user access in Tableau Cloud remains current and secure. Option A is incorrect because manually updating user roles is not an efficient use of SCIM’s capabilities for automation. Option C is incorrect as SCIM is designed for ongoing user account management, not just for periodic audits. Option D is incorrect because SCIM integration is typically managed by administrators or the IT department, not by allowing users to self-provision accounts.

Ensuring that backup copies of the database are also encrypted When encrypting a database for Tableau Server, it is crucial to ensure that backup copies of the database are also encrypted. This prevents scenarios where encrypted data at rest could be compromised through un-encrypted backups, maintaining a consistent level of security for all stored data, whether it is in active use or backed up. Option A is incorrect because while processing power is important for overall performance, it is not the primary concern for ongoing data security in the context of database encryption. Option C is incorrect as network monitoring, while important for security, does not ensure the encryption of data at rest or in backups. Option D is incorrect because setting up a redundant database server focuses on availability and does not directly address the encryption of data or back-ups.

Ensuring the Tableau Server service account has the appropriate SPNs set for the server’s fully qualified domain name (FQDN) Setting the correct SPNs for the Tableau Server service account is crucial for Kerberos authentication. SPNs should be associated with the service account running Tableau Server and must match the server’s FQDN. This enables Kerberos to correctly identify and authenticate the server in a network, ensuring secure communication. Option A is incorrect because SPNs are set for the service account running the server, not for each individual user account in Tableau Server. Option C is incorrect as SPNs are not directly tied to IP addresses but to service accounts and the FQDN of the server. Option D is incorrect because while SSL encryption is important for security, it is not directly related to the configuration of SPNs for Kerberos authentication.

Ensuring compatibility of data sources and security protocols between Tableau Cloud and Tableau Server This approach focuses on the compatibility of data sources and security protocols, which are critical for ensuring that the migrated environment functions correctly and securely. Option A is incorrect because discontinuing Tableau Cloud before starting the migration can lead to data and service disruptions. Option C is incorrect as migrating all users without testing can result in unforeseen issues impacting user experience and data integrity. Option D is incorrect be-cause the migration of visualizations should be prioritized only after ensuring data source compatibility.

Ensuring there is sufficient processing power on the server for the encryption and decryption processes When implementing extract encryption in Tableau Server, it is important to ensure that there is sufficient processing power on the server to handle the additional load caused by the encryption and decryption processes. These processes can be resource-intensive, and adequate processing power will help maintain the server’s performance and responsiveness. Option A is incorrect because disk defragmentation, while it can improve overall performance, does not specifically address the demands of encrypting and decrypting extracts. Option C is incorrect as dedicated network bandwidth primarily affects data transfer speeds and does not directly impact the server’s ability to handle encryption tasks. Option D is incorrect because scheduling encryption during off-peak hours, while it can help mitigate performance impacts, does not address the underlying need for sufficient processing power to handle encryption tasks efficiently.
