What the exam expects

  • Install and activate Tableau Server in an air-gapped environment and restore map backgrounds there.
  • Write HA/DR acceptance criteria for repository failover that match its documented timing and recovery behavior.
  • Plan a Blue/Green upgrade: build and test Green, protect late Blue changes, then cut over.
  • Keep Setup's installation log at a persistent location and know where it goes otherwise.
  • Install the RMT Server and register Agents on every node of a cluster.
  • Automate a Windows install with SilentInstaller.py and its configuration, registration and secrets files.
  • The topology items of 2.1.1 (external services, ensemble, node roles, load balancer) are taught in External services, coordination ensemble and load balancers.

Key terms: air-gapped (no outside network access; software moves only on removable media); ATR (authorization-to-run licensing, with a lease called the ATR duration); Blue/Green (Blue is current production, Green a new installation that replaces it); RMT (Resource Monitoring Tool: RMT Server plus an Agent per node, requires Advanced Management); SilentInstaller.py (community-supported Python script for unattended installs).
