Tableau Server’s user-based licensing (Creator, Explorer, Viewer) ties licenses to individual users—let’s determine compatible authentication methods:

User-Based Licensing:

Licenses are assigned per user, tracked by username.

Authentication determines how users log in—must integrate with licensing.

Option A (Local authentication): Correct.

Details: Users are managed in Tableau Server’s internal database—username/password set manually or via import.

Why: Directly ties to user accounts, fully compatible with licensing.

Option C (Trusted authentication): Correct.

Details: Allows external apps to authenticate users via tickets (e.g., /trusted/).

Why: Maps to Tableau usernames, integrating with licensing—common for embedded analytics.

Config: Trusted IPs or credentials set in TSM.

Option D (Active Directory): Correct.

Details: Uses AD for authentication (LDAP or Kerberos)—users sync to Tableau Server.

Why: AD usernames align with licensing—supports SSO and user management.

Config: Enable via tsm authentication active-directory configure.

Option B (Reliance authentication): Incorrect.

Why: Not a recognized Tableau authentication method—likely a typo (e.g., for "Resilience" or misheard term). No such feature exists.

Why This Matters: Authentication flexibility ensures user-based licensing fits diverse IT environments—critical for adoption.

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.

Tableau Server’s installer configures process instances based on hardware and deployment type (single-node vs. multi-node). For a single-node installation with 4 cores, we need to consider the default process topology. Let’s break this down exhaustively:

Key Processes:

Gateway: Handles incoming requests (1 instance).

Application Server (VizPortal): Manages UI and sessions (1 instance).

VizQL Server: Renders visualizations (2 instances).

Backgrounder: Runs extract refreshes, subscriptions (1 instance).

Data Server: Manages data connections (1 instance).

File Store: Stores extracts (1 instance).

Repository: Metadata database (1 instance, active).

Cluster Controller, Cache Server, etc.: Supporting processes (typically 1 each).

Default Configuration:

On a single-node install, Tableau sets 1 instance per process unless specified otherwise, except for VizQL, which defaults to 2.

The installer doesn’t scale instances linearly with cores (e.g., 4 cores ≠ 4 instances). Post-install, TSM can adjust this (e.g., tsm topology set-process), but the question asks for the installed default.

Minimum hardware (8 cores, 32 GB RAM) suggests higher defaults, but 4 cores still triggers a minimal setup.

Option B (1): Correct with Caveat.

Most processes (e.g., Backgrounder, Gateway, Data Server) default to 1 instance on install, regardless of 4 cores.

VizQL defaults to 2, but the question’s phrasing ("each process") implies a general rule. Historically (and per docs), 1 is the baseline for most, with VizQL as the exception.

Interpretation: Assuming "each" means the typical case, 1 fits most processes on a 4-core single-node setup.

Option A (2): Incorrect. Only VizQL defaults to 2; others don’t.

Option C (8): Incorrect. Far exceeds defaults—8 cores might justify more, but not 4.

Option D (4): Incorrect. Not tied to core count by default; manual config would be needed.

Why This Matters: Understanding defaults aids capacity planning—4 cores is below production minimum (8), so performance tuning may be needed post-install.
