A global financial institution requires a Tableau deployment that ensures continuous operation and data protection. What should be the primary focus…

For a global financial institution requiring continuous operation and data protection, the primary focus must be on building a resilient and fault-tolerant architecture. A multi-node Tableau Server cluster is the foundational design for high availability (HA). This configuration provides redundancy for critical processes like the Repository, File Store, and Gateway. If a node or process fails, the load balancer and automatic failover capabilities ensure that user requests are redirected to healthy nodes, minimizing downtime and maintaining continuous operation. This robust primary site is also the cornerstone of any effective disaster recovery (DR) strategy.

A. A single Tableau Server node represents a single point of failure, which directly contradicts the requirement for continuous operation and high availability.

C. Backups are essential for disaster recovery (data protection) but do not provide high availability (continuous operation); restoring from a backup involves downtime.

D. Relying solely on a cloud service's generic plan is insufficient for a regulated financial institution, which requires its own specific, verifiable DR strategy.

1. Tableau Server Documentation

"High Availability": "You can configure Tableau Server for high availability (HA) by running redundant services on multiple nodes. A Tableau Server installation configured for HA is called a cluster... The key to HA in Tableau Server is redundancy. Multiple nodes running key processes (repository

file store/data engine

and gateway) work together

with a load balancer directing clients to the gateway nodes." (Accessed under the Tableau Server on Windows > Administrator Guide > High Availability section).

2. Tableau Server Documentation

"Disaster Recovery": This section distinguishes between HA and DR. "High availability (HA) refers to a system's ability to continue functioning

even when one or more of its components fail... Disaster recovery (DR)

on the other hand

refers to the process of restoring a system's functionality after a catastrophic failure." This supports why backups alone (Option C) are insufficient as they address DR

not HA. (Accessed under the Tableau Server on Windows > Administrator Guide > Disaster Recovery section).

"Parallel Processors from Client to Cloud

" the principles of dependability via redundancy are discussed. The text explains that availability is a key metric for server dependability and is achieved through redundant components that can take over in case of failure

a principle directly implemented in a multi-node cluster. (See Section 6.8

Dependability

Reliability

and Availability).
