Q20. You may have a DataFrame api_logs with columns:
– user_id
– tokens_used
You need to calculate complete tokens per consumer, however just for customers with greater than 10 API calls. Which strategy is appropriate?

api_logs.groupby("user_id")["tokens_used"].sum()

api_logs[api_logs["tokens_used"] > 10].groupby("user_id").sum()

counts = api_logs.groupby("user_id").dimension()
lively = counts[counts > 10].index
api_logs[api_logs["user_id"].isin(lively)]
  .groupby("user_id")["tokens_used"].sum()

api_logs.groupby("tokens_used")["user_id"].sum()

Q21. You may have a Python record of API responses: 

responses = [ 
{"status": "success", "cost": 0.02}, 
{"status": "error", "cost": 0.00}, 
{"status": "success", "cost": 0.05} 
] 

You need to compute the overall price, however just for profitable responses. Which code is appropriate?

sum(responses["cost"])

complete = 0
for r in responses:
    if r["status"] == "success":
        complete += r["cost"]

complete = responses.price.sum()

complete = 0.02 + 0.05

Q22. You might be working with a pandas DataFrame df that comprises a column textual content. You need to add a column word_count that shops the variety of phrases in every row. Which resolution is appropriate?

df["word_count"] = df["text"].apply(lambda x: len(x.break up()))

df["word_count"] = len(df["text"])

df["word_count"] = df["text"].apply(len)

df["word_count"] = df["text"].depend(" ")

Q23. You might be analyzing mannequin latency utilizing a DataFrame metrics with columns:
– standing
– latency_ms
You need to flag rows the place standing is “okay” and latency exceeds 500 ms. Which code is appropriate? 

metrics["slow"] = metrics["status"] == "okay" and metrics["latency_ms"] > 500

metrics["slow"] = metrics.question("standing == 'okay' latency_ms > 500")

metrics["slow"] = metrics["latency_ms"] > 500

metrics["slow"] = (metrics["status"] == "okay") & (metrics["latency_ms"] > 500)

Q24. You may have a big pandas DataFrame logs with columns:
– user_id
– response_code
You need a record of distinctive customers who encountered a minimum of one 500 error. Which strategy is appropriate?

logs.groupby("user_id")["response_code"].depend()

logs["user_id"].distinctive()

logs[logs["response_code"] == 500].depend()

Q25. You might be calling an LLM API and need to restrict the generated output to 100 tokens. Which parameter controls this?

Q26. A GenAI assistant solutions coverage questions utilizing inner paperwork. When info is lacking, the assistant generally guesses. Which design change most successfully prevents this? 

Q27. You might be designing an enterprise LLM system that should resist immediate injection makes an attempt whereas imposing firm tone and compliance guidelines. Which message-layer design is most safe?

Q28. An AI agent can entry a Search software and a Calculator software. It generally performs calculations earlier than trying to find required information. Which prompting technique greatest enforces appropriate software order?

Q29. A regulated assistant should present solutions that embody actual doc citations. If a number of sources battle, it should refuse to reply. Which superior immediate technique greatest enforces this habits?

Q30. You need an AI agent to elucidate its reasoning, execute a software name, consider the end result, after which proceed till the duty is full. Which sample supplies this structured hint?

Q31. An inner AI assistant should generate solutions utilizing solely a offered data base. If the data base doesn’t include related info, the assistant should reply with: “No info accessible in firm information.” Which precept ensures this habits?

Q32. An AI agent receives a posh request that requires a number of dependent steps. You need the agent to decompose the duty, validate constraints, and produce a plan earlier than execution. Which prompting strategy is greatest?

Q33. A purchasing assistant should all the time verify real-time stock information earlier than answering availability questions. Which instruction greatest enforces this habits?

Q34. You might be debugging an agent that makes use of a number of instruments. You want full visibility into every reasoning step, software name, parameters, and outcomes. Which sample greatest helps this requirement?

Q35. An agent should implement a strict approval workflow: sure actions require validation earlier than continuing. The agent generally skips validation. Which design change is most effective?

Q36. A compliance assistant mustn’t ever generate solutions that mix inner coverage with exterior assumptions. If required info is lacking, it should explicitly refuse. Which immediate engineering precept most immediately enforces this?

Q37. An LLM-based code era system should create appropriate Python code. To enhance accuracy, the mannequin ought to first internally plan the answer however expose solely the ultimate code to customers. Which method greatest helps this?

Q38. You might be designing an orchestration layer the place an LLM should convert a consumer request right into a dependency-aware execution plan earlier than calling any instruments. Which prompting sample is most applicable?

Q39. A buyer assist agent receives structured software output and should reply in clear, pleasant language with out exposing uncooked system information. Which habits is most applicable?

Q40. A security-critical AI agent should implement a non-negotiable rule: it mustn’t ever reply questions on worker salaries. The place should this rule be positioned to make sure it can’t be overridden?

Rating!

In the event you scored effectively on these, like greater than 30 appropriate, you then’re already pondering past prompts and into system design.

If some questions shocked you, then they’ve served their objective. As immediate engineering isn’t memorization, it’s judgment. As a substitute of brute forcing all attainable solutions to questions, creating a sound understanding of the issue ought to be the main target.

In the event you’re discovering it too exhausting to undergo the questions you may contemplate taking a free immediate engineering course.
