The Backgrounder process in Tableau Server handles tasks like extract refreshes and subscriptions—let’s explore its concurrency:

Backgrounder Behavior:

Each instance is single-threaded for task execution—one task at a time per Backgrounder.

Multiple Backgrounders (e.g., in multi-node setups) increase parallelism, but a single Backgrounder is limited to 1 concurrent task.

Queue: Additional tasks wait in the queue, prioritized by their priority (1–100).

Option A (One): Correct.

Details: A single Backgrounder executes one task (e.g., an extract refresh) until completion before starting the next.

Config: Add more Backgrounders via TSM (tsm topology set-process -n node1 -pr backgrounder -c 2) for more concurrency.

Option B (Two): Incorrect.

Why: Not natively supported—a single Backgrounder doesn’t multi-thread tasks.

Option C (Three): Incorrect.

Why: Exceeds the single-threaded design.

Option D (Unlimited): Incorrect.

Why: Concurrency is fixed at 1 per instance—resources affect queue processing speed, not simultaneous tasks.

Why This Matters: Understanding Backgrounder limits guides scaling—more instances mean more parallel tasks, critical for heavy workloads.

Tableau Server supports multi-tenancy via sites, each with customizable settings managed by server or site administrators. Let’s analyze what’s configurable per site:

Site Settings: Found in the web UI under Site > Settings > General. Server admins can override site admin settings.

Option B (Limitation on storage space): Correct.

Details: Server admins can set a storage quota per site (e.g., 100 GB) to cap disk usage for extracts and workbooks.

How: In TSM or site settings (if enabled)—e.g., tsm configuration set -k site.storage.quota -v 100000.

Impact: Prevents one site from monopolizing resources in multi-site deployments.

Option D (Language and locale): Correct.

Details: Each site can set its language (e.g., English, French) and locale (e.g., date/number formats).

How: Site settings UI—e.g., "Language: French, Locale: France."

Impact: Tailors the user experience per site’s audience.

Option A (Ability to embed credentials): Incorrect.

Details: Embedding credentials (e.g., in data sources) is a server-wide setting (tsm data-access), not per-site. Site admins can’t override it.

Option C (Limitation on number of users): Incorrect.

Details: User limits are tied to licenses (server-wide), not configurable per site. Site admins manage user assignments, not quotas.

Why This Matters: Site-specific settings enable tailored governance and resource allocation in multi-tenant environments.

Registering Tableau Server from the command line involves providing configuration details (e.g., identity store, license) via the tsm register command. Let’s explore this fully:

Registration Process:

Run during initial setup or to update settings (e.g., after changing AD/LDAP config).

Uses a configuration file to pass parameters to TSM.

Command: tsm register --file .

File Format:

Tableau Server uses JSON for configuration files in TSM commands like tsm register.

Example:

json

CollapseWrapCopy

{

"identityStore": {

"type": "local",

"domain": "example.com"

}

}

JSON is structured, machine-readable, and aligns with Tableau’s modern CLI design.

Option C (JSON): Correct.

Official format for tsm register, per documentation and practical use.

Option A (YML): Incorrect.

While tabsvc.yml exists internally, it’s not for registration—tsm register uses JSON.

Option B (XML): Incorrect.

Older Tableau configs used XML (e.g., workgroup.yml pre-TSM), but TSM standardized on JSON.

Option D (HTTP): Incorrect.

HTTP is a protocol, not a file format—irrelevant here.

Why This Matters: Correct file format ensures seamless registration, avoiding CLI errors in setup or migrations.

In a high-availability (HA) Tableau Server setup, the Repository (PostgreSQL) has an active and passive instance. Failover occurs if the active Repository fails. Let’s dive into the process:

HA Setup:

Two Repository instances across nodes (active/passive).

Failover switches to the passive instance if the active one becomes unavailable (e.g., crash, network issue).

Cluster Controller:

Role: Monitors all processes (e.g., Repository, File Store) across nodes, detecting failures via heartbeats and status checks.

Failover Decision: If the active Repository stops responding, Cluster Controller initiates failover, promoting the passive instance to active.

Coordination: Works with Coordination Service (ZooKeeper) to update topology but makes the initial detection call.

Option A (Cluster Controller): Correct.

Why: It’s the watchdog process, constantly monitoring Repository health and triggering failover when needed.

Option B (Coordination Service): Incorrect.

Role: ZooKeeper maintains cluster state and coordinates topology updates post-failover, but doesn’t detect the failure—Cluster Controller does.

Option C (Gateway): Incorrect.

Role: Routes client requests—unrelated to internal process monitoring or failover.

Option D (Backgrounder): Incorrect.

Role: Executes background tasks—no involvement in Repository failover decisions.

Why This Matters: Understanding failover ensures HA reliability—Cluster Controller is the linchpin for resilience.

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.

When an extract refresh fails on Tableau Server, troubleshooting requires identifying the root cause—e.g., connectivity issues, resource constraints, or configuration errors. The Backgrounder process handles extract refreshes, so it’s a key focus, but the best diagnostic tool depends on granularity and context. Let’s explore this thoroughly:

Extract Refresh Process:

An extract refresh pulls data from a source (e.g., database, file) into a .hyper file stored on Tableau Server.

The Backgrounder executes these tasks based on schedules or manual triggers.

Errors could stem from: database connectivity, credentials, file access, resource overload, or task misconfiguration.

Option B (Background Tasks for Extracts administrative view): Correct. This is the most direct and detailed method:

Location: In the Tableau Server web UI, go to Server > Status > Background Tasks for Extracts (or site-specific under Site > Status).

Details Provided:

Task name, schedule, and workbook/data source.

Start/end times and status (e.g., Failed, Success).

Error messages (e.g., "Cannot connect to database," "Permission denied").

Why It’s Best: It pinpoints the exact failure (e.g., "timeout," "invalid credentials") for the specific refresh, offering actionable insights without needing to dig through logs manually. Server or site administrators can access this view to diagnose issues quickly.

Example: If the error is "Database login failed," you’d check credentials in the data source settings next.

Option A (Status of the Backgrounder process via tsm status -v): Partially useful but insufficient:

What It Shows: Running/stopped status of all processes (e.g., "Backgrounder: RUNNING").

Limitation: It confirms if Backgrounder is operational but doesn’t reveal why a specific task failed—no error details or task-level granularity.

Use Case: If Backgrounder is stopped or crashed, this might indicate a broader issue, but the question implies a single refresh error, not a server-wide failure.

Option C (The UNC path to the extract’s data source): Relevant but secondary:

Context: If the data source is a file (e.g., CSV on a network share), the UNC path (e.g., \\server\share\file.csv) must be accessible.

Why Not First: The error could be unrelated (e.g., database issue, not file-based). The admin view (B) would reveal if it’s a path issue first, guiding you to check the UNC path only if indicated (e.g., "File not found").

Practical Note: Backgrounder needs share permissions and the Run As account must access it—checking this without context wastes time.

Option D (Whether project permissions are set to Locked): Unlikely cause:

Permissions Impact: Locked permissions restrict who can edit/view content, not whether an extract refresh runs—that’s tied to the data source’s connection settings and Backgrounder execution.

Exception: If the refresh user lacks "Connect" permission to the data source, it might fail, but this is rare (owner/schedule typically has access). The admin view would flag this.

Why This Matters: The Background Tasks view is Tableau’s purpose-built tool for extract diagnostics, saving time and reducing guesswork in production environments.
