Which two are characteristics of an agile data center? (Choose two.)

Question

Options

• AProvision a UPS module with a different power capacity.
• BChange out plug types when new IT equipment is installed.
• CDesign for "worse case" capacity to prevent future downtime.
• DHave N+1 redundancy in part of the data center and 2N in another part based on equipment criticality.

• A
  6% (3)
• B
  80% (39)
• C
  2% (1)
• D
  12% (6)

Explanation

Note: The question asks for two answers, but only "B" is listed as correct. Based on agile data center principles, B and D are the two correct answers - this appears to be an incomplete answer key.

Why B is correct: An agile data center is built for flexibility and adaptability. Swapping plug types to accommodate new IT equipment reflects that ability to evolve without major infrastructure overhauls - a defining agile trait.

Why D is correct: Mixing redundancy levels (N+1 for less critical systems, 2N for critical ones) is a hallmark of agile design - it right-sizes resilience to actual need rather than applying a one-size-fits-all approach.

Why A is wrong: Simply provisioning a UPS with a different capacity isn't inherently agile - it's a one-time replacement, not a design philosophy. Agility is about the ability to adapt, not a single swap.

Why C is wrong: Designing for worst-case is a traditional, over-provisioning mindset. Agile data centers avoid locking in excess capacity; they scale dynamically to match demand.

Memory tip: Think of "agile" like software sprints - adapt to change (B: swap plugs for new gear) and right-size for reality (D: match redundancy to criticality). Worst-case design and one-off hardware swaps are the opposite of that mindset.
