Which two statements describe the parallel redundant UPS configuration? (Choose two.)

Question

Options

• AIt uses older and outdated technology.
• BThe parallel redundant UPS configuration is not scalable.
• CIf one UPS module goes down, the other UPS module(s) assumes the load.
• DBoth modules must be the same design, manufacturer, rating, technology, and configuration.

• A
  4% (1)
• B
  4% (1)
• C
  85% (22)
• D
  8% (2)

Explanation

In a parallel redundant UPS configuration, multiple UPS modules share the load simultaneously, and if one module fails, the remaining module or modules automatically take over the full load without interruption - this is exactly what option C describes and is the core purpose of redundancy in this design.

Option A is wrong because parallel redundant UPS is a modern and widely deployed approach, not outdated technology. Option B is wrong because parallel redundant configurations are actually highly scalable - additional modules can be added to increase capacity or redundancy as needs grow. Option D is a common misconception; while matching specifications is a best practice in some implementations, it is not a defining characteristic of the configuration itself and is not universally required across all parallel redundant systems.

Memory tip: Think of parallel redundant UPS like a relay race - multiple runners (modules) share the course together, and if one drops the baton, another is already running alongside and picks up without the team losing a step.
