Model Selection & Cost — CCAO-F Practice Question
A representative Claude Certified Associate - Foundations (CCAO-F) exam question on Model Selection & Cost. Work through it below, then read why each option is right or wrong.
This question is part of the free Claude Certified Associate - Foundations practice test.
Short answer
The correct answer is A. Route routine cases to a faster lower-cost model and escalate uncertain cases to a more capable model or human.
Routing by task difficulty preserves quality where it matters while controlling cost and latency. A single-model policy ignores the workload's clear risk tiers.
The Question
A team has thousands of low-risk product descriptions to classify into a fixed taxonomy and a small number of difficult ambiguous cases. What is the best model strategy?
Why A is correct
Routing by task difficulty preserves quality where it matters while controlling cost and latency. A single-model policy ignores the workload's clear risk tiers.
Why the other options are wrong
Option B does not satisfy the requirement in the scenario. Review the explanation above: the correct choice (A) 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 (A) is the only one that fully meets every constraint stated in the question.
Option D does not satisfy the requirement in the scenario. Review the explanation above: the correct choice (A) is the only one that fully meets every constraint stated in the question.
Key idea: Model Selection & Cost
Routing by task difficulty preserves quality where it matters while controlling cost and latency. A single-model policy ignores the workload's clear risk tiers. On the CCAO-F exam, questions in the "Product and Model Selection" 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.
