Untimed. Answers are graded when you submit, with explanations and spaced-repetition scheduling.

Question 1easy
What are the two fundamental integration patterns for connecting AI to other systems?
Training and inferenceREST (synchronous request/response) and webhooks (async event notification)Embedding and retrievalDocker and Kubernetes
Question 2easy
Which HTTP verb is appropriate for an AI action endpoint that performs work?
GETPOSTHEADOPTIONS
Question 3medium
Why must you return the correct HTTP status code (e.g. 429 vs 400)?
For prettier logsCallers react to codes — a 429 should be retried, a 400 (their mistake) should not; wrong codes break retry logicCodes are decorativeThe model requires them
Question 4medium
Why should you never expose an unauthenticated AI endpoint?
It runs slowerAnyone who finds it can call it, burning your tokens and budgetIt can't return JSONIt disables webhooks
Question 5medium
What is a webhook?
A request you send to poll for changesAn endpoint another system POSTs to when an event happens, so you react without pollingA type of vector indexA caching layer
Question 6hard
Why should a webhook handler ack quickly and process slow work asynchronously?
To use more tokensThe sender expects a fast 2xx; a slow inline LLM call can cause a sender timeout and retry, duplicating processingBecause webhooks can't call LLMsTo avoid returning JSON
Question 7hard
Why must you verify a webhook's signature before trusting its payload?
To decompress itThe URL is public, so anyone can POST forged events; a signature (HMAC over the raw body) proves the real senderTo speed up parsingSignatures are optional decoration
Question 8hard
What does idempotency mean for an integration endpoint?
It runs faster on the second callProcessing the same request twice has the same effect as processing it once (no double charge/send/row)It rejects all duplicate requests as errorsIt caches the model's output
Question 9hard
What is the standard mechanism to make a side-effecting endpoint idempotent?
A higher temperatureAn idempotency/event key — record a unique id per event and skip the side effect if already processedRetrying more aggressivelyRemoving authentication
Question 10medium
When should you use synchronous REST rather than a webhook?
When a system reacts to an event and nothing waitsWhen the caller needs the answer now to continue (a user waiting on a classification or chat reply)Never — always use webhooksOnly for nightly jobs
Question 11hard
Which are REST/webhook integration pitfalls? (Select all that apply)
Exposing an unauthenticated AI endpointTrusting an unverified webhook payloadDoing a slow LLM call inline before acking a webhookMaking side-effecting handlers idempotent
Select all that apply.
Question 12medium
What reliability property (one word) makes processing the same request twice equivalent to once?
Question 13hard
What cryptographic technique (acronym) is commonly used to verify a webhook came from the real sender?
