Certified Prompt Engineering — Techniques - Practice Quiz — Quiz in Progress

Q1. Which best captures the key idea of "Chain-of-thought"? AProcess many items individually (map), then combine results (reduce) BAsking the model to reason step by step before answering boosts accuracy on logic... CCompare two prompt versions on the same inputs and keep the winner DHR aligns people systems — hiring, growth, pay, culture — with strategy

Q2. Which best captures the key idea of "Tree-of-thought"? ADemand valid JSON matching a schema, with a fallback for missing fields BViruses, ransomware and spyware spread via downloads and attachments; antivirus plus caution stops most CDiagnose from error and stack trace DExplore several reasoning paths, evaluate each, then pick the best - useful for complex...

Q3. Which best captures the key idea of "Self-consistency"? APaste-link Excel tables into Word/PowerPoint so numbers update automatically BGenerate multiple independent answers and take the most common one to reduce errors CBuild projects, read errors, and code daily — consistency beats intensity DDrag the fill handle to extend series and copy formulas with relative references

Q4. Which best captures the key idea of "Decomposition"? AWork backwards from the deadline; define milestones as checkpoints BDecide what 'good' means - accuracy, tone, format, completeness CAlways defer diagnosis and treatment to professionals DBreak a hard problem into smaller sub-problems the model can solve in sequence

Q5. Which best captures the key idea of "Least-to-most prompting"? ALabels, contrast, keyboard navigation and alt text make sites usable by everyone BAgree, disagree, interrupt politely, and summarise — key phrases ready CAgents store intermediate results to use in later steps DSolve the simplest sub-task first and build up to the full problem

Q6. Which best captures the key idea of "Reflection and self-critique"? AHave the model critique its own answer against criteria, then improve it BTrade depth against cost and latency CAsk for unit tests covering happy path and edge cases DDraft clear, structured academic prose

Q7. Which best captures the key idea of "Verification prompts"? ASort by column and filter rows to see exactly the data you need BTime multiplies money; starting early beats starting big CFrame design decisions persuasively DAsk the model to check its answer or find its own mistakes before finalising

Q8. Which best captures the key idea of "Reasoning vs speed trade-off"? AFollow 3-2-1: three copies, two media, one offsite (cloud) — backups turn disasters into... BDeeper reasoning costs more tokens and time; use it where accuracy matters most CSummarise a long document first, then act on the summary to save context DChunking, visualisation and memory palaces multiply recall
