Tableau Server’s search functionality relies on an indexed catalog of content (workbooks, data sources, etc.) stored in the Repository. If a user can see a workbook in the UI (e.g., underContent > Workbooks) but not find it via search, the search index may be outdated or corrupted. This can happen due to:

Indexing delays after publishing.

Server maintenance or crashes affecting the index.

Option D (Run the tsm maintenance reindex-search command): Correct. This command rebuilds the search index, ensuring all content (including the user’s workbook) is properly cataloged and searchable. Steps:

Stop Tableau Server (tsm stop).

Run tsm maintenance reindex-search.

Start Tableau Server (tsm start).This is a server administrator task and resolves systemic search issues.

Option A (Re-publish the workbook with keywords): Incorrect. Re-publishing might update the index for that workbook, but it doesn’t fix a broader indexing problem. Keywords enhance relevance, not indexing itself.

Option B (Add tags to the workbook): Incorrect. Tags improve searchability but don’t address an index failure. If the workbook isn’t indexed, tags won’t help.

Option C (Log out, and then log back in): Incorrect. This refreshes the user session but doesn’t affect the server-side search index.

Why This Matters: A reliable search index is critical for content discovery in large deployments—reindex-search ensures consistency.

Single Sign-On (SSO) allows users to authenticate once (e.g., via a corporate identity provider) and access Tableau Server without re-entering credentials. Tableau Server supports several SSO methods:

OpenID Connect (OIDC): An OAuth 2.0-based protocol for SSO, configured via Tableau’s SAML settings with an OIDC-compatible IdP (e.g., Google, Okta).

Kerberos with Active Directory: A ticket-based SSO protocol, widely used in Windows environments with AD integration.

SAML: A flexible SSO standard using XML assertions, supporting various IdPs (e.g., ADFS, PingFederate).

Let’s evaluate:

Option A (OpenID Connect): Correct. OIDC is an SSO method, implemented as a SAML variant in Tableau Server, enabling seamless login.

Option C (Kerberos with Active Directory): Correct. Kerberos provides SSO in AD environments, delegating authentication to the domain controller.

Option D (Security Assertion Markup Language - SAML): Correct. SAML is a core SSO method in Tableau, widely adopted for enterprise integrations.

Option B (Local Authentication): Incorrect. Local Authentication uses Tableau’s internal user database, requiring manual credential entry—no SSO support.

Why This Matters: SSO enhances user experience and security by leveraging existing identity systems, reducing password fatigue.

Installing Tableau Server on Windows requires an account with sufficient privileges to configure services, write to the file system, and manage registry settings. Let’s analyze this in depth:

Installation Requirements:

The installer creates services (e.g., Tableau Server Gateway), writes to Program Files and ProgramData, and configures TSM.

It needslocal administrative privilegeson the machine to perform these tasks.

Post-install, a "Run As" account can be set for services (e.g., NT AUTHORITY\NetworkService), but this is separate from the install account.

Option C (An account in the local administrator group): Correct.

Why: The account must be in the local Administrators group to:

Install software (UAC elevation).

Configure services and ports.

Write to protected directories (e.g., C:\Program Files\Tableau).

Examples: A local admin (e.g., Administrator) or a domain user added to the Administrators group (e.g., DOMAIN\AdminUser).

Process: Log in as this account, run the installer, and provide TSM admin credentials during setup.

Option A (A local user account): Incorrect.

A standard local user (not in Administrators) lacks permissions—installation would fail with "Access Denied" errors.

Option B (A domain user account): Incorrect unless clarified.

A domain user without local admin rights can’t install. If it’s in the Administrators group, it qualifies, but C is more specific.

Option D (NT AUTHORITY\NetworkService): Incorrect.

This is a built-in service account for running services (default "Run As" post-install), not for executing the installer—an interactive user account is required.

Why This Matters: Using the right account prevents install failures and ensures secure configuration—critical for production setups.

Comments on Tableau Server visualizations facilitate collaboration. Let’s explore what’s supported:

Comments Feature: Enabled per site (Settings > General > Allow Comments). Users with "Add Comment" permission can post on views.

Option B (Text): Correct.

Details: The primary content type—users type free-form text in the comment box.

Use: Notes, questions, or feedback (e.g., "Sales spiked here—why?").

Option C (@mentions): Correct.

Details: Typing @username notifies the mentioned user via email or the UI (if notifications are enabled).

Use: Directs comments to specific people (e.g., "@John, check this trend").

Option A (Interactive snapshots of a view): Incorrect.

Details: Snapshots (static images) aren’t supported in comments—users must take screenshots externally and can’t embed them interactively.

Option D (Images - jpg, png): Incorrect.

Details: No attachment or image embedding in comments—text and mentions only. Workaround: Link to an image hosted elsewhere.

Why This Matters: Comments enhance teamwork, but their simplicity (text + mentions) keeps the interface lightweight and focused.

Tableau Server uses caching to speed up workbook loading by storing query results. After a scheduled extract refresh updates the data, the cache may need recomputing—let’s dive into the mechanics:

Caching Basics:

VizQL Cache: Stores rendered views and query results for faster access.

Refresh Trigger: A scheduled refresh updates the underlying extract (.hyper), but the cache isn’t automatically invalidated—it’s demand-driven.

Recompute Conditions: Tableau recomputes the cache when the workbook is accessed (viewed) and its data has changed (e.g., via refresh).

Evaluation:

Option B (The workbook has upcoming scheduled refresh tasks): Correct.

Why: An upcoming refresh task indicates the workbook relies on an extract with a schedule. After the refresh runs, the data changes, priming the cache for recomputation on next view. Without a schedule, no refresh occurs, so this is a prerequisite.

Detail: Schedules are set inSchedules > Tasks—e.g., "Daily at 2 AM."

Option D (The workbook has been viewed recently): Correct.

Why: Viewing triggers cache recomputation if the data has changed (e.g., post-refresh). Tableau uses a "lazy caching" model—cache updates only when a user loads the workbook, ensuring fresh results.

Detail: "Recently" isn’t strictly defined but implies post-refresh access.

Option A (Published in the last month): Incorrect.

Why: Publish date is irrelevant—cache recomputation ties to data changes and access, not publication timing.

Option C (All Users group has permission rule allowing access): Incorrect.

Why: Permissions enable viewing, but recomputation requires actual access (viewing) and a refresh event, not just potential access.

Why This Matters: Caching balances performance and freshness—understanding triggers prevents stale data surprises.

Tableau Server is designed for production environments and is supported only on server-class operating systems, not desktop operating systems. As of the latest documentation (aligned with knowledge up to March 21, 2025), the supported operating systems for Tableau Server on Windows are:

Windows Server 2016

Windows Server 2019

Windows Server 2022 (added in later versions, but relevant as of 2025).

Desktop operating systems like Windows 7 or Windows 10 are not supported for production installations due to stability, security, and performance requirements.

Option A (Windows 7): Incorrect. Windows 7 is a desktop OS and is not supported for Tableau Server. It’s also end-of-life as of January 2020.

Option B (Windows 10): Incorrect. Windows 10 is a desktop OS and not supported for production Tableau Server deployments, though it may be used for testing in non-production scenarios.

Option C (Windows Server 2019): Correct. This is a supported server OS for Tableau Server.

Option D (Windows Server 2016): Correct. This is also a supported server OS for Tableau Server.
