What is the recommended first step when sizing ECS?

Question

Options

• AThe solutions architect uses the ECS sizer to develop a configuration recommendation.
• BThe customer uses the Configuration Assistance Tool to input their exact needs.
• CThe solutions architect uses the downloaded version of the ECS sizer to create an accurate sizing.
• DThe customer uses the downloaded version of the ECS sizer to create an accurate sizing.

• A
  86% (19)
• B
  9% (2)
• C
  5% (1)

Explanation

Option A is correct because the recommended first step in the ECS sizing process is for the solutions architect to use the ECS sizer tool to develop an initial configuration recommendation - this establishes a baseline before any detailed or customer-specific refinement occurs.

Why the distractors are wrong:

• B is wrong because the Configuration Assistance Tool is a customer-facing input tool, but it is not the first step in the sizing workflow - the SA's recommendation comes first.
• C is wrong because the downloaded version of the ECS sizer is used for more accurate, detailed sizing, which happens in a later step, not the first.
• D is wrong on two counts: the customer does not drive the first step, and using the downloaded sizer is a subsequent (not initial) action.

Memory tip: Think of it as a funnel - the SA starts broad with the standard ECS sizer to build an initial recommendation, then the process narrows toward more precise tools (the downloaded sizer) and customer-specific inputs. "SA + standard sizer = first step."
