The system retrieved a relevant document before generating the reply.

Medium question

Why can agentic automation be more powerful than classic automation?

Question 22 of 50

Agentic systems can reason through unclear steps instead of only following fixed branches.

Medium question

Which option best describes the basic agent loop?

Question 23 of 50

Correct answer: C. Understand, plan, act, observe, and adjust

That loop captures how many practical agents operate.

Medium question

Why is adding too many tools risky in a first version?

Question 24 of 50

Correct answer: D. It increases complexity and creates more failure points

Each extra tool adds more surface area for confusion, errors, and permissions issues.

Medium question

What is usually the best first step when building an agent?

Question 25 of 50

Correct answer: A. Start with one repeated problem and define the job clearly

Clear scope is more useful than starting with maximum complexity.

Medium question

Why are logs important in agent systems?

Question 26 of 50

Correct answer: B. They show what the agent tried, saw, and decided

Logs are vital for debugging, trust, and evaluation.

Medium question

Which action most clearly deserves an approval gate?

Question 27 of 50

Correct answer: C. Sending money or deleting important data

High-impact actions should usually require explicit human approval.

Medium question

What problem does a vector database mainly solve?

Question 28 of 50

Correct answer: D. Storing and searching embeddings efficiently

Vector databases are built for semantic retrieval at scale.

Medium question

Why might one agent review another agent’s work?

Question 29 of 50

Correct answer: A. To improve quality before results reach the user

A review layer helps catch mistakes, policy issues, or weak reasoning.

Medium question

Which trade-off appears often when choosing a model?

Question 30 of 50

Correct answer: B. Speed, cost, context, and quality must be balanced

Model selection is usually a balancing act, not a single-metric choice.

Medium question

What best describes hallucination?

Question 31 of 50

Correct answer: C. Confident output that is not well grounded

Hallucination is believable language without reliable grounding.

Medium question

Why do clean tool interfaces matter?

Question 32 of 50

Correct answer: D. They make agent behavior easier to predict and debug

Simple interfaces reduce ambiguity and make systems easier to maintain.

Medium question

When is a multi-agent setup a good idea?

Question 33 of 50

Correct answer: A. When specialized roles clearly improve the workflow

Multiple agents help when specialization adds real value.

Medium question

Why should onboarding for an AI product be simple?

Question 34 of 50

Correct answer: B. So new users reach a first win quickly and gain confidence

Early clarity improves adoption and reduces user frustration.

Medium question

What does continuous improvement mean in agent systems?

Question 35 of 50

Correct answer: C. Using tests, feedback, and measurements to refine the workflow

Reliable systems improve through measured iteration.

Medium question

Which case best fits a research agent?

Question 36 of 50

Trust grows when the system behaves predictably and transparently.

Medium question

What is the best summary of ROI for an agent project?

Question 40 of 50

Correct answer: D. The value created should outweigh setup and operating cost

A strong business case compares benefit against cost.

Hard question

A team wants one agent to research, draft, approve, and execute financial actions automatically. What is the biggest concern?

Question 41 of 50

Correct answer: A. High-risk actions need stronger separation, checks, and approvals

Risky financial workflows need layered control, not one unchecked path.

Hard question

Why can a powerful model still fail in production?

Question 42 of 50

Correct answer: B. Because the full system also depends on prompts, tools, state, and evaluation

Production quality is about the whole system, not just the core model.

Hard question

When is a multi-agent design worse than a single-agent design?

Question 43 of 50

Correct answer: C. When the task is simple and extra coordination adds overhead

If specialization adds little value, the extra complexity is not worth it.

Hard question

Why is prompt injection especially dangerous for tool-using agents?

Question 44 of 50

Correct answer: D. Manipulated instructions can trigger unsafe real-world actions

Tool access increases the impact of bad instructions.

Hard question

Why keep a human-in-the-loop even when the model is strong?

Question 45 of 50

Correct answer: A. Some decisions still carry legal, financial, or ethical weight

Strong models still need human judgment in high-stakes situations.

Hard question

Which design choice most improves long-term maintainability?

Question 46 of 50

Correct answer: B. Clear instructions, narrow tools, logs, tests, and modular workflows

Maintainability grows when the system is observable and modular.

Hard question

Why is it risky to judge an agent only by a polished demo?

Question 47 of 50

Correct answer: C. Demos often hide edge cases, failures, and operational reality

Real-world reliability appears under messy conditions, not only happy paths.

Hard question

Before fine-tuning an internal agent, what should a team often improve first?

Question 48 of 50

Correct answer: D. Grounding, instructions, retrieval quality, and workflow design

Many failures come from weak system design before model tuning is even needed.

Hard question

What is the most complete explanation of trust in agent products?

Question 49 of 50

Correct answer: A. Trust comes from accuracy, transparency, safe boundaries, and predictable behavior over time

Users trust systems that behave well repeatedly, not just occasionally.

Hard question

What mindset best fits the future of agent work?

Question 50 of 50
