Tableau Server has specific hardware requirements for production environments to ensure stability and performance. The minimum recommended free disk space for a production installation is 50 GB. This accounts for:

The installation itself (approximately 1–2 GB).

Space for log files, temporary files, and extracts managed by the File Store and Data Engine.

Room for backups and operational overhead.

The full minimum hardware recommendations for a single-node production deployment are:

8 CPU cores (2.0 GHz or faster).

32 GB RAM.

50 GB free disk space (on the system drive, typically C: on Windows).

Option A (32 GB): Incorrect. While 32 GB is the minimum RAM requirement, it’s insufficient for disk space in production.

Option B (50 GB): Correct. This matches Tableau’s official recommendation for production environments.

Option C (15 GB): Incorrect. 15 GB is the minimum for a non-production or trial installation, not production.

Option D (64 GB): Incorrect. While 64 GB exceeds the minimum, it’s not the specified requirement—50 GB is sufficient.

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 in Schedules > 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 can record performance metrics for workbooks to troubleshoot slow-loading views. This feature must be enabled at the site level (via Settings > General > Allow Performance Recording). Once enabled, you can trigger recording for a specific view by modifying its URL.

The correct syntax is to append :record_performance=yes& to the view URL, immediately after the session ID. For example:

Original URL:

Modified URL: &

After loading the view with this parameter, a performance recording is generated and accessible via the Performance option in the toolbar.

Option B (Type :record_performance=yes& at the end of the view URL, immediately after the session ID): Correct. This follows Tableau’s documented method for enabling performance recording.

Option A (Click the Performance link in the toolbar): Incorrect. The Performance link appears only after recording is triggered via the URL; it’s not the method to enable it.

Option C (Type :record_performance=yes& immediately before the session ID): Incorrect. The parameter must follow the session ID (e.g., :iid=1) to function correctly.

Option D (Delete the session ID in the URL and reload the view): Incorrect. The session ID is required for the view to load properly; removing it breaks the URL.
