Tableau Server's user-based licensing model assigns licenses to individual users (Creator, Explorer, Viewer) rather than machines or cores. Key features include:

Subscription license: Licenses are typically subscription-based, renewed annually or monthly, aligning with Tableau's pricing model.

Distinct user roles: It supports three roles (Creator, Explorer, Viewer), each with specific capabilities, enabling granular access control.

Option A (A subscription license): Correct. User-based licenses are subscription-based by default.

Option B (Enables distinct user roles): Correct. The model defines Creator, Explorer, and Viewer roles.

Option C (Restricts the number of machine cores): Incorrect. This applies to core-based licensing, not user-based.

Option D (A perpetual license): Incorrect. Perpetual licenses were phased out; user-based licenses are subscription-based as of recent models.

The VizQL Server process in Tableau Server handles rendering visualizations and processing queries for users viewing dashboards or workbooks. During installation, Tableau Server automatically configures the number of VizQL instances based on the number of processor cores on the machine, following this rule:

Default VizQL instances = 2 per node, unless manually adjusted post-installation.

In multi-node setups, additional instances may be added based on core count, but the question specifies a single server with 16 cores.

The installer does not scale VizQL instances linearly with core count by default (e.g., it doesn't set 1 instance per 4 cores). Instead:

For a single-node installation, the default is 2 VizQL instances, regardless of core count (assuming the minimum hardware requirements are met: 8 cores, 32 GB RAM).

Administrators can later adjust this using TSM (e.g., tsm topology set-process) based on performance needs, but the question asks for the default configured by the installer.

Option A (4): Incorrect. Four instances might be configured manually for a 16-core server, but it's not the default.

Option B (6): Incorrect. Six instances exceed the default for a single node.

Option C (10): Incorrect. Ten instances are far beyond the default and would require manual configuration.

Option D (2): Correct. The installer sets 2 VizQL instances by default on a single-node installation.

Tableau Server uses a PostgreSQL database as its repository to store metadata, user information, and permissions. In a high-availability (HA) setup with multiple nodes, there are typically two repository instances: one active and one passive. The 'preferred active repository' refers to designating which repository instance should take priority as the active one. This is managed through Tableau Services Manager (TSM).

The correct method to set the preferred active repository is by using the tsm configuration set command. Specifically, you would use a command like:

tsm configuration set -k pgsql.preferred_host -v <hostname>

This command allows an administrator to specify the preferred host for the active repository, ensuring control over which node takes precedence in an HA environment.

Option B (tabcmd set command) is incorrect because tabcmd is a command-line utility primarily used for administrative tasks like managing users, groups, and content (e.g., publishing workbooks), not for configuring server topology or repository settings.

Option C (TSM browser client's Maintenance page) is incorrect because the Maintenance page in the TSM web interface is used for tasks like backups, restores, and cleanup, but it does not provide an option to set the preferred active repository.

Option D (TSM browser client's Configuration Topology page) is partially relevant since the Topology page displays the current configuration of services across nodes, including the repository. However, it does not allow direct modification of the preferred active repository; this must be done via the tsm command line.

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.
