Option B (Tableau Server browser interface): Correct.
Groups: Go to Users > Groups > Add Group, name it, and optionally sync with Active Directory.
Projects: Go to Content > Projects > New Project, set name, description, and permissions.
Details: The web UI is intuitive, requiring server/site administrator rights. It’s ideal for manual, ad-hoc creation with immediate visibility.
Permissions: For projects, you can set default permissions or lock them here.
Option C (tabcmd): Correct.
Groups: tabcmd creategroup "GroupName" creates a local group. Add users with tabcmd addusers "GroupName" --users "user1,user2".
Projects: tabcmd createproject -n "ProjectName" -d "Description" creates a project.
Details: tabcmd is a command-line tool for batch operations or scripting (e.g., automating group/project setup). It requires a server admin login (tabcmd login).
Limitation: No AD sync via tabcmd—that’s UI or REST API territory.
Option D (REST API): Correct.
Groups: Use the POST /api/api-version/sites/site-id/groups endpoint with a payload (e.g., {"group": {"name": "GroupName"}}). Supports AD import too.
Projects: Use POST /api/api-version/sites/site-id/projects (e.g., {"project": {"name": "ProjectName", "description": "Desc"}}).
Details: The REST API is programmatic, ideal for integration with external systems or bulk automation. Requires authentication via a token and server/site admin rights.
Power: Offers full control, including nested projects and custom permissions.
Option A (tsm customize): Incorrect.
Purpose: tsm customize modifies TSM UI branding (e.g., logos, colors) via commands like tsm customize --logo "path/to/logo.png".
Why Wrong: It’s unrelated to creating groups or projects—it’s for cosmetic server configuration, not content/user management.
