AWS Cert Prep Coach prompts

Act as an experienced AWS Solutions Architect explaining concepts to a junior engineer.

Topic: <AWS_SERVICE_OR_CONCEPT>
My current level: <BEGINNER | INTERMEDIATE | RUSTY>
My use case: <WHAT_I_AM_TRYING_TO_BUILD_OR_LEARN_IT_FOR>

Explain it in 4 layers:
1. The 1-sentence elevator pitch — what problem it solves.
2. The 3-bullet mental model — how it actually works under the hood.
3. A concrete worked example (with numbers / config / a tiny diagram in ASCII).
4. The 2-3 most common exam traps about this concept (multiple choice gotchas, naming collisions with sibling services, default-quota surprises).

Keep it under 350 words. No fluff. If something is commonly misunderstood, call it out as ⚠️ TRAP.

Generate 10 multiple-choice questions in the style of the AWS Certified <CERT_NAME> exam, all on the topic of <DOMAIN_OR_SERVICE>.

Rules:
- Each question has exactly 4 options labeled A/B/C/D.
- Scenario-based, not definition-recall.
- Include 2 questions where multiple options look correct but only one matches the AWS best practice.
- Include 1 question with a deprecated/wrong answer (so I learn to spot outdated content).
- After ALL 10 questions, give me an answer key with 1-2 sentence explanations + the AWS doc URL pattern (you don't need exact URLs — just `docs.aws.amazon.com/<service>/...`).

Format the answer key in a separate code block so I can hide it while taking the drill.

I just got this practice question wrong. Diagnose what I'm missing.

Question: <PASTE_QUESTION>

Options:
A) <OPT_A>
B) <OPT_B>
C) <OPT_C>
D) <OPT_D>

My answer: <MY_ANSWER>
Correct answer: <CORRECT_ANSWER>

Do this:
1. In 2 sentences, explain why my answer was wrong — but specifically diagnose which AWS concept I'm confusing, not just 'because the correct answer is X'.
2. In 2 sentences, explain why the correct answer is right.
3. Give me the 1 sentence I should memorize about this concept to never miss it again.
4. List the 2 sibling services / features that are commonly confused with this one, with a 1-line differentiator for each.

No recap of the question. No fluff. Diagnostic mode.

Create a 1-page exam cheat-sheet for AWS <SERVICE_NAME> in the context of the <CERT_NAME> certification.

Structure (use markdown, fit on one printed page):

## What it is (2 lines)
## Default limits / quotas (table: limit | default | hard cap)
## Pricing dimensions (bullet list — what you pay for, not the numbers)
## Most-tested features (3-5 bullets, exam-relevant only)
## ⚠️ Exam traps (3 bullets — confusion points that recur on exams)
## When NOT to use it (1-2 bullets — sibling service is better)
## Sample 1-line scenario → service mapping (3 examples)

Keep it terse. No paragraphs longer than 2 lines. This is for last-night review, not learning.

I'm evaluating which AWS service fits this scenario. Help me decide.

Scenario: <DESCRIBE_USE_CASE_INCLUDING_CONSTRAINTS_LIKE_LATENCY_COMPLIANCE_BUDGET>

Candidates: <SERVICE_1>, <SERVICE_2>, <SERVICE_3>, <SERVICE_4>

For each candidate, give me:
- One-line fit-score: 🟢 ideal / 🟡 workable / 🔴 wrong tool
- The single feature that makes it fit or not
- The hidden cost or constraint people forget

Then give me your final pick + the AWS Well-Architected pillar argument that supports it (Reliability, Security, Cost Optimization, Performance Efficiency, Operational Excellence).

If two candidates are tied, name a concrete sub-scenario where each one wins.
