Which statement describes brownfield deployments?

Question

Options

• ABrownfield deployments allow for more modular and scalable design than greenfield
• BBrownfield deployments are commonly used and can be restrictive.
• CBrownfield deployments are considered more expensive than greenfield deployments.
• DBrownfield deployments use all new equipment.

• A
  3% (1)
• B
  88% (35)
• C
  5% (2)
• D
  5% (2)

Explanation

Brownfield deployments involve working within existing infrastructure - building on top of or integrating with systems already in place. Option B is correct because brownfield environments are the norm in enterprise IT (most organizations have legacy systems), and those pre-existing systems impose constraints that limit design choices, making the deployment restrictive.

Why the distractors are wrong:

• A is backwards - greenfield deployments offer more flexibility and modularity since there are no legacy constraints.
• C is not a defining characteristic; greenfield can actually be more expensive due to building from scratch, so cost comparison is not a reliable distinguisher.
• D describes greenfield, not brownfield - new equipment and a clean slate is the hallmark of greenfield deployments.

Memory tip: Think of a brown, overgrown field - something already exists there, and you have to work around it. Green field = fresh, untouched grass (start from zero). Brown = existing "dirt" you must navigate.
