A 10-question skill check

Untimed. Answer the way you would handle the work. Your score says whether to start with practice or sit a full timed set, and which areas to review if you miss any.

Question 1 of 10

A team is building a document-analysis assistant on the Claude API. Each request sends the same set of tool definitions, a long system prompt containing policy guidelines, and a growing multi-turn conversation. They add a cache_control breakpoint at the end of the system prompt to reduce cost and latency.

For each statement, select Yes or No.

Appending a new user turn to the end of the conversation invalidates the cached prefix.

Editing one of the tool definitions invalidates the cache for the system prompt that follows it.

Reading from the cache resets its five-minute lifetime.

Cache writes are billed at the same rate as uncached input tokens.
