Question 1
AdvancedDesign a Tableau Infrastructure · Design an appropriate process topology
A global financial institution is planning to migrate its on-premises Tableau Server infrastructure to a cloud-based architecture on AWS. The current deployment serves 5,000 users with a strict 99.9% uptime SLA. The architect must design a High Availability (HA) cluster that ensures no single point of failure and supports automatic failover for the repository. Which topology design meets these requirements while minimizing the minimum number of nodes required?
Answer and explanation
Correct answer: D
To support automatic repository failover, Tableau Server requires a minimum of three nodes. This allows for a quorum in the Coordination Service (Ensemble) and enables having one active repository and at least one passive repository (often two are recommended for redundancy) to ensure seamless failover without manual intervention. A 2-node cluster cannot support automatic repository failover.
