Answer before reveal
Your draft
Write the answer you would give in an interview. The model answer stays hidden until you have drafted at least a short response.
A strong answer
Separate discovery from change, create an explicit input contract, preview targets, use ShouldProcess where appropriate, bound concurrency, checkpoint results, log every decision, handle partial failure and verify the final state independently.
Show it concretely
1PS> Import-Csv .\targets.csv | ForEach-Object {
2PS> # validate -> preview -> change -> verify
3PS> }
Expect this follow-up
How would you resume after 40 percent of the targets succeeded and the network failed?
