What is the first step when preparing to install ES?

Question

Options

• AInstall ES.
• BDetermine the data sources used.
• CDetermine the hardware required.
• DDetermine the size and scope of installation.

• A
  3% (1)
• B
  6% (2)
• D
  91% (32)

Explanation

Determining the size and scope of installation (D) must come first because it establishes the foundational parameters that drive every subsequent decision - without knowing how large or complex the deployment will be, you cannot meaningfully proceed with any other planning step.

• A (Install ES) is wrong because you cannot install anything responsibly before planning; jumping straight to installation skips all preparation.
• B (Determine data sources) is wrong because data source analysis is a downstream activity - the scope of the installation determines which data sources are even relevant.
• C (Determine hardware required) is wrong because hardware requirements depend on the size and scope; you can't size your hardware until you know what you're deploying.

Memory tip: Think of it as the "outer-in" rule - always start with the biggest picture (scope) before narrowing to specifics (hardware, data sources, then installation). Scope → Hardware → Data → Install.
