Tableau SCA-C01 Exam Dumps - Actual Questions Answers

In a high-availability (HA) Tableau Server setup, theRepository(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.

In Tableau Server, roles and permissions dictate who can perform specific administrative tasks. A "server administrator" has full control over the entire Tableau Server deployment, while site administrators manage specific sites. Some tasks are restricted to server administrators due to their server-wide impact.

Option B (Adding a site): Creating a new site in a multi-site Tableau Server environment is a server-level task that only a server administrator can perform. Sites are logical partitions within the server, and adding a site affects the overall server structure. Site administrators cannot create new sites; they can only manage existing ones.

Option D (Adding users): Adding users to Tableau Server (e.g., via the TSM interface or tabcmd) is a server administrator task when it involves adding users at the server level or assigning them to the default site. While site administrators can add users to their specific site in a multi-site environment, the initial addition of users to the server requires server administrator privileges. The question’s phrasing (“always require”) suggests a server-wide context, making this a correct choice.

Option A (Creating a schedule): This is incorrect because both server administrators and site administrators can create schedules for tasks like extract refreshes or subscriptions within their scope. It’s not exclusive to server administrators.

Option C (Locking project permissions): This is incorrect because locking project permissions can be done by a site administrator or project leader with appropriate permissions. It’s a project-level action, not a server-level task requiring a server administrator.

Tableau Server uses internal secrets (tokens) for secure communication between its processes (e.g., Repository, File Store). These are automatically generated during installation and can be regenerated if compromised or for security maintenance. The command to update these is:

tsm security regenerate-internal-tokens: This regenerates the internal security tokens, ensuring all processes use the new tokens after a restart.

Option C (tsm security regenerate-internal-tokens): Correct. This is the documented command for updating internal secrets.

Option A (tsm data-access caching set -r 1): Incorrect. This command configures caching behavior, not security tokens.

Option B (tsm licenses refresh): Incorrect. This refreshes license data, unrelated to internal secrets.

Option D (tsm security validate-asset-keys): Incorrect. This validates encryption keys for assets, not internal tokens.
