Model Selection & Routing — CCDV-F Practice Question
A representative Claude Certified Developer - Foundations (CCDV-F) exam question on Model Selection & Routing. Work through it below, then read why each option is right or wrong.
Short answer
The correct answer is D. Use a smaller model for validated routine classification and route complex or uncertain cases to a more capable model.
Validated task-based routing applies capability where needed while controlling routine cost. Escalation should use measurable difficulty or confidence signals, not randomness.
The Question
An app handles simple intent classification and occasional complex contract analysis. Which design best balances quality and cost?
Why D is correct
Validated task-based routing applies capability where needed while controlling routine cost. Escalation should use measurable difficulty or confidence signals, not randomness.
Why the other options are wrong
Option A does not satisfy the requirement in the scenario. Review the explanation above: the correct choice (D) is the only one that fully meets every constraint stated in the question.
Option B does not satisfy the requirement in the scenario. Review the explanation above: the correct choice (D) is the only one that fully meets every constraint stated in the question.
Option C does not satisfy the requirement in the scenario. Review the explanation above: the correct choice (D) is the only one that fully meets every constraint stated in the question.
Key idea: Model Selection & Routing
Validated task-based routing applies capability where needed while controlling routine cost. Escalation should use measurable difficulty or confidence signals, not randomness. On the CCDV-F exam, questions in the "Model Selection and Optimization" domain test whether you can map a scenario's constraints to the right choice. Read the requirement carefully, eliminate options that violate any single constraint, and pick the one that satisfies all of them with the least operational overhead.
