What are two prerequisites of capacity planning in a network design? (Choose two.)

Question

Options

• Apredicting traffic projections for future growth
• Bunderstanding historical application behavior
• Cunderstanding current application behavior
• Dunderstanding historical growth

• A
  90% (43)
• B
  4% (2)
• D
  6% (3)

Explanation

Capacity planning requires knowing where you are now (C) and where you're going (A) - you need to understand current application behavior to establish a baseline, and you need traffic projections to anticipate future demand and size the network accordingly. Without both, you're either guessing at the starting point or flying blind about growth.

Why B and D are wrong: Historical data is useful context but not a prerequisite - you can plan capacity without knowing past behavior or past growth rates, as long as you have current state and future projections. History informs forecasts but doesn't replace them; the actual planning inputs are the current baseline and the forward-looking projection.

Memory tip: Think of capacity planning like planning a road trip - you need to know your current location (C: current behavior) and your destination (A: future projections). Where you've been (history) is nice to know but won't stall the trip if you don't have it.
