Easy — CCAO-F Practice Quiz

Question 1

A developer is adding a currency-conversion capability to a Claude-powered assistant. They want Claude to be able to invoke this capability during the conversation. When defining the tool in the API request, which three components must the developer provide for the tool definition to be valid and usable by Claude?

Accepted Answer

A name, a description, and an input JSON schema describing the parameters

Answer

A name, the URL of the external service, and an authentication token

Answer

A description, an example output, and a maximum token limit for the result

Answer

A unique ID, a temperature value, and a stop sequence for the tool

Question 2

A developer is defining a currency-conversion tool for Claude. They have written a detailed description and a complete input JSON schema, but they are unsure what to put in the tool's 'name' field and how Claude uses it. What is the primary purpose of the 'name' field in a tool definition?

Accepted Answer

It is a unique identifier Claude uses to reference the tool when it requests to invoke it, and that you match against when returning results

Answer

It is the natural-language text Claude reads to decide whether the tool is relevant to the user's request

Answer

It defines the required parameters and their data types that Claude must supply when calling the tool

Answer

It is a display label shown to end users and has no effect on how Claude selects or calls the tool

Question 3

You are building a weather assistant that lets Claude fetch current conditions. You need to define a tool so Claude knows how to call it. Which combination of elements must every tool definition include for Claude to correctly request and populate the tool call?

Accepted Answer

A name, a description, and an input_schema written as a JSON Schema object

Answer

A name, an example response payload, and the API endpoint URL to call

Answer

A unique ID, a temperature setting, and a list of stop sequences

Answer

A description and a pre-filled assistant message showing the expected output

Question 4

A developer is building a feature that lets users upload a photo of a handwritten recipe so Claude can transcribe it. They are new to the Messages API and want to understand, at a conceptual level, how to send the image to Claude. Which statement correctly describes how image inputs work in the Messages API?

Accepted Answer

An image is included as a content block within a user message, alongside any text content blocks, so Claude can analyze the picture and the accompanying instructions together.

Answer

Images must be placed in the system prompt because that is the only place the model reads non-text data.

Answer

The image must be sent as a separate assistant-role message before the user asks their question.

Answer

Claude cannot process images directly; the developer must run OCR themselves and paste the extracted text into a user message.
