When troubleshooting Kerberos authentication issues related to SPNs in Tableau Server, what common problem should be investigated first?
A. Checking if the Kerberos tickets are expiring too quickly
B. Verifying that the SPNs are correctly set for the Tableau Server service account
C. Ensuring that the network firewall allows Kerberos traffic to pass through
D. Confirming that all users have Kerberos enabled on their client machines
Explanation:
Why B is Correct?
Service Principal Names (SPNs) are critical for Kerberos authentication to work. They uniquely identify the Tableau Server service in the Kerberos realm.
Common SPN issues include:
Missing or duplicate SPNs (e.g., HTTP/tableau.example.com not registered or assigned to multiple accounts).
Incorrect SPN formats (e.g., using the server’s IP instead of its FQDN).
Tableau’s Kerberos Troubleshooting Guide lists SPN checks as the first step.
Why Other Options Are Secondary?
A. Ticket expiration: Rarely the root cause—default ticket lifetimes (e.g., 10 hours) are usually sufficient.
C. Firewall rules: Kerberos uses port 88 (UDP/TCP), but SPN misconfigurations are more common.
D. Client Kerberos settings: Clients inherit Kerberos configs from the domain; issues here are uncommon unless the domain is misconfigured.
Reference:
Microsoft’s SPN Troubleshooting Guide.
Final Note:
B is the #1 Kerberos issue. Always start with SPNs before investigating tickets (A), firewalls (C), or clients (D).
When planning to implement Tableau Bridge in an organization using Tableau Cloud, what factor is critical to ensure live data connectivity from on-premises data sources?
A. Allocating a dedicated server solely for running Tableau Bridge to manage all data connections
B. Ensuring that Tableau Bridge is installed on a machine with a constant and stable internet connection
C. Installing Tableau Bridge on every user's local machine to decentralize data connectivity
D. Configuring Tableau Bridge to refresh data only during off-peak hours to reduce network load
Explanation:
Why B is Correct?
Tableau Bridge acts as a secure gateway between Tableau Cloud and on-premises data sources, requiring:
Uninterrupted internet access to sync queries/results with Tableau Cloud.
Stable connectivity to avoid disruptions in live data feeds.
Tableau’s Bridge Documentation emphasizes this as a prerequisite.
Why Other Options Are Incorrect?
A. Dedicated server: Helpful for scalability but not mandatory—Bridge can run on any machine meeting requirements.
C. Installing on every user’s machine: Inefficient and hard to manage—Bridge is designed for centralized deployment.
D. Off-peak refreshes: Only applies to extracts, not live connections (which require real-time access).
Key Requirements for Bridge Setup:
Install Bridge on a machine with:
24/7 uptime (e.g., VM, dedicated server).
Access to on-prem data sources (firewall rules for databases).
Configure network stability:
Use wired connections (avoid Wi-Fi).
Monitor with tools like ping or traceroute.
Reference:
Tableau’s Bridge System Requirements.
Final Note:
B is the foundational requirement. Options A/C/D are situational optimizations, but without stable internet, Bridge fails. Always test connectivity pre-deployment.
What is an essential step in implementing extract encryption in Tableau Server to enhance data security?
A. Encrypting only those extracts that contain sensitive information, while leaving others un-encrypted for performance reasons
B. Enabling extract encryption at the server level to ensure all extracts are encrypted, regard-less of their content
C. Relying on database-level encryption alone to secure all data used in Tableau extracts
D. Manually encrypting each extract using third-party software before uploading it to Tableau Server
Explanation:
Why B is Correct?
Server-level extract encryption ensures all data extracts (.hyper or .tde) stored on Tableau Server are encrypted by default, providing uniform security without manual intervention.
Why Other Options Are Incorrect?
A. Selective encryption: Leaves non-sensitive data vulnerable and complicates management.
C. Database-level encryption: Doesn’t protect extracts after data is extracted from the database.
D. Manual third-party encryption: Impractical for scale and breaks Tableau’s native functionality.
Steps to Implement Server-Level Encryption:
Generate a strong encryption key (e.g., 256-bit AES).
Reference:
Tableau’s Security Hardening Guide.
Final Note:
B is the only comprehensive approach. Options A/C/D create security gaps or operational inefficiencies. Always back up the encryption key separately!
For a company using Tableau Server primarily for complex data visualizations that require significant processing time, which configuration key should be adjusted?
A. Increase the "gateway.timeout" value to allow longer processing time for complex visualizations
B. Decrease the "vizqlserver.session.expiry.timeout" value to ensure faster visualization rendering
C. Limit the "backgrounder.extractsrefresh" value to reduce the load on the server
D. Decrease the "dataserver.timeout" value for quicker data retrieval
Explanation:
Why A is Correct?
The gateway.timeout setting controls how long Tableau Server waits for a response before timing out a request.
Complex visualizations (e.g., large datasets, intricate calculations) may require more processing time than the default timeout allows. Increasing this value prevents premature failures.
This is a direct and targeted fix for slow-rendering dashboards.
Why Other Options Are Incorrect?
B. Decreasing vizqlserver.session.expiry.timeout: Shortens session lifespans but does not address rendering delays.
C. Limiting backgrounder.extractsrefresh: Reduces extract jobs but unrelated to visualization rendering speed.
D. Decreasing dataserver.timeout: Forces quicker query failures—counterproductive for slow data sources.
Reference:
Tableau’s Timeout Settings Documentation recommends adjusting gateway.timeout for heavy workloads.
Final Note:
A is the only solution that directly addresses slow visualizations. Options B/C/D either worsen the problem or target unrelated subsystems. Always monitor performance after changes.
A large multinational corporation plans to deploy Tableau across various departments with diverse data access needs. The IT team needs to determine the optimal role distribution for users. Which of the following approaches best meets these requirements?
A. Assign all users the "Viewer" role to maintain data security and control
B. Provide "Creator" roles to department heads and "Explorer" roles to their team members
C. Implement a uniform "Explorer" role for all users to simplify management
D. Tailor user roles based on specific department needs and data access levels
Explanation:
Why Option D is Correct:
Role-based access control (RBAC) is critical for multinational corporations with diverse needs:
Creators: Data analysts/scientists (need full access to build/workbooks).
Explorers: Power users (edit dashboards but not data sources).
Viewers: Read-only access for stakeholders.
Custom roles (via Tableau Server/Cloud) can further restrict row-level security (RLS) or project access.
Reference: Tableau Roles and Permissions Guide.
Why Other Options Are Incorrect:
A) All "Viewers":
Too restrictive (blocks self-service analytics).
B) Only department heads as "Creators":
Bottlenecks innovation (team members may need Explorer/Creator rights).
C) Uniform "Explorers":
Over-provisions access (e.g., finance vs. marketing needs differ).
Implementation Steps:
Audit departments (e.g., Finance: "Creators" for models, "Viewers" for execs).
Leverage groups in Tableau Server/Cloud for bulk role assignments.
Apply RLS for data-level restrictions.
In configuring Connected App authentication for Tableau Server, what is a key step to ensure se-cure and proper functionality of the integration?
A. Creating a unique user account in Tableau Server for each user of the connected app
B. Registering the connected app in Tableau Server and obtaining client credentials (client ID and secret)
C. Allocating additional storage on Tableau Server for data accessed by the connected app
D. Setting up a dedicated VPN channel between Tableau Server and the connected app
Explanation:
Why Option B is Correct:
Connected Apps in Tableau Server use OAuth 2.0 for secure authentication. The critical step is:
Registering the app in Tableau Server (via Admin settings).
Generating client credentials (client ID and secret) to authenticate API calls.
This ensures:
Secure token-based access (no password sharing).
Granular permissions (scopes control what the app can do).
Reference: Tableau Connected Apps Guide.
Why Other Options Are Incorrect:
A) Unique user accounts:
Defeats the purpose of OAuth (apps should not use individual user accounts).
C) Extra storage:
Irrelevant to authentication (storage is managed separately).
D) Dedicated VPN:
Overkill for OAuth—SSL/TLS encryption is sufficient.
Steps to Configure a Connected App:
Go to Tableau Server Admin > Settings > Connected Apps.
Click Register App and enter:
App Name (e.g., "DataWarehouse-Integration").
Redirect URI (for OAuth callbacks).
Save to get Client ID and Secret.
When implementing database encryption for Tableau Server, which step is essential to protect sensitive data at rest?
A. Enabling SSL encryption for all data in transit between the Tableau Server and its data-bases
B. Configuring Transparent Data Encryption (TDE) on the database used by Tableau Server
C. Setting up a dedicated firewall to protect the database server hosting the Tableau Server data
D. Regularly changing the database user's passwords used by Tableau Server
Explanation:
Why B is Correct?
Transparent Data Encryption (TDE) encrypts the entire database at rest, including:
Tableau Server’s repository database (PostgreSQL).
Underlying data sources (e.g., SQL Server, Oracle) used for extracts.
TDE protects against physical theft, unauthorized disk access, or backup breaches.
Tableau’s Security Best Practices recommend TDE for compliance (e.g., HIPAA, PCI DSS).
Why Other Options Are Insufficient?
A. SSL for data in transit: Doesn’t protect stored data (at rest).
C. Dedicated firewall: Secures network access but not the actual data files.
D. Password rotation: Good practice but doesn’t encrypt data.
Steps to Implement TDE:
For Tableau’s Repository:
Enable TDE in PostgreSQL (if using external PostgreSQL).
For Data Sources:
Configure TDE in SQL Server/Oracle (e.g., CREATE DATABASE ENCRYPTION KEY).
Reference:
Microsoft’s TDE Documentation.
Final Note:
B is the only true at-rest encryption. Options A/C/D address other security layers but not storage encryption. Always pair TDE with access controls
In planning the migration of their Tableau Server from an Active Directory-based identity store to an LDAP-based system, what should be the primary focus to maintain user access and security?
A. Migrating user passwords directly from Active Directory to LDAP
B. Ensuring that user roles and permissions are accurately mapped and transferred to the new LDAP system
C. Relying on default settings in LDAP without custom configurations
D. Completing the migration in the least possible time without testing
Explanation:
Why Option B is Correct:
The primary focus of migrating from Active Directory (AD) to LDAP is to preserve user access and security. This requires:
Accurate mapping of AD groups to LDAP groups to maintain role-based permissions in Tableau.
Verifying permissions (e.g., "Creator," "Explorer," "Viewer") are correctly assigned in the new LDAP system.
Failure to map roles/permissions correctly can lead to broken access (users locked out) or security risks (over-provisioned permissions).
Reference: Tableau LDAP Migration Guide.
Why Other Options Are Incorrect:
A) Migrating passwords:
Passwords cannot be directly transferred between AD and LDAP. Users must reset passwords or use a sync tool (e.g., Microsoft Identity Manager).
C) Relying on default LDAP settings:
Defaults often don’t match AD’s structure, causing authentication failures. Custom filters (e.g., objectClass=user) are usually needed.
D) Skipping testing:
High-risk approach—untested migrations often break access for critical users.
Key Steps for a Secure Migration:
Pre-migration:
Audit AD groups/permissions in Tableau.
Match AD groups to LDAP groups (e.g., CN=Tableau_Creators,OU=Groups,DC=example,DC=com).
Migration:
Use Tableau’s tsm authentication commands to switch to LDAP.
Test with a pilot group before full cutover.
Post-migration:
Validate permissions with tsm permissions commands.
Monitor logs for authentication errors.
For a large organization using Tableau Server, what should be included in an automated complex disaster recovery plan to ensure rapid recovery of services?
A. Frequent, automated backups of Tableau Server data, configuration, and content, stored in an off-site location
B. A single annual full backup of the Tableau Server, complemented by periodic manual checks
C. Continuous, real-time backups of all user interactions and changes on the Tableau Server
D. Utilizing only RAID configurations for data storage to prevent data loss
Explanation:
Why A is Correct?
Frequent, automated backups ensure minimal data loss and enable rapid restoration.
Backups should include:
Content (workbooks, data sources, extracts).
Configuration (server settings, user permissions).
Repository database (PostgreSQL for Tableau Server metadata).
Off-site storage protects against physical disasters (e.g., fire, flood).
Tableau’s Disaster Recovery Guide mandates this approach for enterprises.
Why Other Options Are Insufficient?
B. Annual backups + manual checks: Far too infrequent—risks massive data loss.
C. Real-time backups of user interactions: Overkill—not feasible for most organizations and doesn’t cover configurations.
D. RAID only: Prevents hardware failures but not logical errors (e.g., corrupted data, accidental deletions).
Key Components of a Disaster Recovery Plan:
Automated daily backups (e.g., via tsm maintenance backup).
Tested restore procedures (validate backups work!).
Geographically redundant storage (e.g., AWS S3, Azure Blob).
Documented rollback steps for critical failures.
Reference:
NIST SP 800-34: Requires automated, off-site backups for IT disaster recovery.
Tableau’s Backup Best Practices.
Final Note:
A is the only enterprise-grade solution. RAID (D) and annual backups (B) are inadequate, while real-time backups (C) are impractical. Always pair backups with regular recovery drills.
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?
A. Implement a single Tableau Server node to simplify management
B. Establish a multi-node Tableau Server cluster with load balancing and failover capabilities
C. Rely solely on regular data backups without additional infrastructure considerations
D. Use a cloud-based Tableau service without any on-premises disaster recovery plans
Explanation:
Why B is Correct?
A multi-node cluster is essential for high availability (HA) and disaster recovery (DR) in a global financial institution because it provides:
Failover: If one node fails, others take over (e.g., using Tableau Server’s distributed architecture).
Load balancing: Distributes user traffic evenly (e.g., via VizQL processes).
Geographic redundancy: Nodes can span data centers for regional outages.
Tableau’s High Availability Guide mandates this approach for mission-critical deployments.
Why Other Options Are Inadequate?
A. Single node: A single point of failure—unacceptable for financial institutions.
C. Backups alone: Backups restore data but cause downtime during failures.
D. Cloud-only: Cloud services (e.g., Tableau Cloud) still require DR plans (e.g., hybrid backups).
Key Components of HA/DR for Financial Institutions:
Multi-node cluster:
Primary + standby nodes (e.g., 3+ nodes for fault tolerance).
Automated failover:
Configured via tsm topology commands.
Disaster recovery site:
Sync backups to a secondary location (e.g., AWS S3, Azure Blob).
Reference:
FINRA Regulatory Notice 21-19: Requires HA/DR for financial data systems.
Tableau’s Disaster Recovery Guide.
Final Note:
B is the only enterprise-grade solution. Options A/C/D violate compliance and risk outages. Always design for zero single points of failure.
When installing Tableau Server in an air-gapped environment, which of the following steps is essential to ensure a successful installation and operation?
A. Enabling direct internet access from the Tableau Server for software updates
B. Using a physical medium to transfer the Tableau Server installation files to the environment
C. Configuring Tableau Server to use a proxy server for all external communications
D. Implementing a virtual private network (VPN) to allow remote access to the Tableau Server
Explanation:
Why B is Correct?
An air-gapped environment has no internet connectivity, so:
Tableau Server installation files (e.g., .rpm, .deb, or .exe) must be transferred via USB drive, DVD, or internal network.
All dependencies (e.g., libraries, drivers) must also be included
.
Tableau’s Offline Installation Guide details this process.
Why Other Options Are Impossible or Insecure?
A. Enabling internet access: Violates the air-gapped requirement.
C. Proxy server: Still requires external connectivity.
D. VPN: Defeats the purpose of air-gapping (no remote access allowed).
Steps for Air-Gapped Installation:
Download Tableau Server + dependencies on a connected machine.
Transfer files via secure physical media.
Activate offline: Use a license file instead of online activation.
Reference:
Tableau’s Air-Gapped Security Guidelines.
Final Note:
B is the only viable method. Options A/C/D compromise air-gapped security. Always validate checksums for transferred files.
When managing a Tableau Server environment on a Linux system, which method is recommended for deploying automated backup scripts?
A. Configuring the scripts to run automatically via the Tableau Server web interface
B. Using cron jobs to schedule and execute backup scripts at regular intervals
C. Relying on a third-party cloud service to handle all backup processes
D. Manually initiating backup scripts through the Linux terminal as needed
Explanation:
Why B is Correct?
Cron is the standard Linux tool for scheduling automated tasks, including Tableau Server backups.
It allows:
Regular backups (e.g., daily at 2 AM).
Logging for audit trails.
No manual intervention (unlike Option D).
Tableau’s Backup Documentation explicitly recommends cron for automation.
Why Other Options Are Less Effective?
A. Web interface: Tableau Server’s UI doesn’t support script scheduling.
C. Third-party cloud: Overkill for backups unless hybrid cloud is required (cron is free and native).
D. Manual execution: Risky—human errors lead to missed backups.
Reference:
Tableau’s Automated Backup Guide.
Final Note:
B is the most reliable and lightweight method. Options A/C/D either don’t work or add unnecessary complexity. Always test scripts in staging first!
