From a risk management perspective, which of the following is the BEST approach when implementing a large and complex data center IT infrastructure?

Question

Options

• AA big bang deployment with a successful proof of concept
• BPrototyping and a one-phase deployment
• CA deployment plan based on sequenced phases
• DSimulating the new infrastructure before deployment

• A
  5% (2)
• B
  15% (6)
• C
  75% (30)
• D
  5% (2)

Explanation

Phased deployment (C) is the best risk management approach because it breaks a complex rollout into controlled stages, allowing teams to identify and resolve issues incrementally before they cascade across the entire infrastructure - minimizing blast radius at each step.

Why the distractors fall short:

• A (Big bang): Even with a successful proof of concept, deploying everything at once maximizes risk exposure; a single failure can bring down the entire system with no fallback.
• B (Prototyping + one-phase): Prototyping validates concepts but a single deployment phase still carries the same all-or-nothing risk as a big bang approach.
• D (Simulation): Simulating the environment is a valuable preparatory step, but it doesn't replace an actual phased rollout - simulations can't anticipate every real-world variable.

Memory tip: Think of it like building a skyscraper - you don't pour all the concrete at once. You sequence the phases (foundation → frame → floors) so each stage can be inspected before the next begins. In risk management, sequenced = safe.
