tsm maintenance ziplogs collects and compresses log files from all server processes into an archive, primarily for diagnosing problems or sharing with Tableau Support. It does not back up configuration, repository, or extract data - that is the role of tsm maintenance backup.

Subscriptions in Tableau Server deliver workbook views to users via email on a schedule. Group subscriptions apply to all group members-let's unpack this:
* Group Subscription Mechanics:
* Created via Workbooks > Actions > Subscribe > Select Group.
* Delivers content to all users in the group at the time the subscription runs (e.g., daily PDF).
* Dynamic: Membership updates (additions/removals) are reflected automatically on the next run.
* Option C (The subscription updates automatically to include the new user): Correct.
* Details: When you add a user to the group (e.g., via Users > Groups > Add Users), Tableau Server's subscription process queries the group's current membership at runtime. The new user receives the subscription on the next scheduled delivery-no manual action needed.
* Example: Group "Sales" has a 9 AM subscription. Add a user at 8 AM-they get the email tomorrow at 9 AM.
* Option A (Admin receives notice to approve/deny): Incorrect.
* Why: No approval workflow exists for group membership changes in subscriptions-it's automatic.
* Option B (Creator must manually edit): Incorrect.
* Why: Subscriptions are tied to the group, not a static user list-manual edits aren't required for membership changes.
* Option D (Only members at creation time): Incorrect.
* Why: This would be true for individual subscriptions (static list), but group subscriptions are dynamic.
Why This Matters: Dynamic group subscriptions streamline content delivery as teams evolve, reducing admin overhead.

This command regenerates internal authentication tokens used between Tableau Server's own processes, typically run as a security precaution (e.g., after suspected token exposure). It doesn't touch user passwords, SSL certificates, or site URL namespaces.

Kerberos delegation allows Tableau Server to pass a user's Kerberos credentials to a data source for seamless authentication (SSO)-let's explore which sources support it:
* Kerberos Overview:
* Used with Active Directory (AD) for SSO in Windows environments.
* Tableau Server delegates the user's ticket to the data source, avoiding embedded credentials.
* Requires:
* Data source support for Kerberos.
* Proper configuration (e.g., SPN, constrained delegation).
* Supported Data Sources: Per Tableau's documentation:
* Option A (Teradata): Correct.
* Details: Supports Kerberos delegation-common in enterprise data warehouses.
* Config: Enable in TSM (tsm authentication kerberos configure) and set SPN for Teradata.
* Option C (SQL Server): Correct.
* Details: Fully supports Kerberos-widely used with AD-integrated SQL Server instances.
* Config: Requires AD setup and "Trustworthy" delegation in SQL Server.
* Option D (SAP HANA): Correct.
* Details: Supports Kerberos SSO via delegation-popular in SAP ecosystems.
* Config: Needs HANA Kerberos setup (e.g., keytab) and Tableau Server integration.
* Option B (PostgreSQL): Incorrect.
* Why: Supports Kerberos authentication natively, but Tableau Server doesn't enable delegation to PostgreSQL-users must embed credentials or use other methods (e.g., OAuth).
Why This Matters: Kerberos delegation enhances security by avoiding stored passwords-knowing supported sources ensures SSO feasibility.
