Choosing chunk overlap | AWS Certified AI Practitioner (AIF-C01) original practice question

2.2Standard

Split long policies for retrieval.

Preserve meaning at section boundaries.

Choose two practices.

Hint 1: Focus on the requirement

Identify what must change and what must remain unchanged. Then choose the command whose scope matches that requirement.

Hint 2: Check each command's role

Separate commands that display information, change state, remove data, or affect a child process.

見出しや段落など意味の境界を優先してチャンクを分割する: Chunks retain meaningful units.
適度な重なりを評価し、重複トークン・検索品質・文脈保持を比較する: Boundary context is balanced with expense.
全てを固定文字数で切り、見出しを無視する: Meaningful boundaries may break.
重なりを無限に増やす: Duplication and cost grow.

Detailed explanation

CorrectSplit at headings or paragraph boundaries when possible

Chunks retain meaningful units.

CorrectEvaluate overlap against retrieval quality, context, duplicate tokens, and cost

Boundary context is balanced with expense.

IncorrectUse fixed characters and ignore headings

Meaningful boundaries may break.

IncorrectIncrease overlap without limit

Duplication and cost grow.

An example you can run in a temporary verification environment.

Foundation review

Check whether the command acts on the current shell, a new process, an existing process, or a file.
