🟢 Easy (5)¶
1. What is the difference between recognition and recall, and why does it matter for study?
Show answer
Recognition (seeing an answer and knowing it) uses a different neural pathway than recall (producing the answer from memory). Recall is far more cognitively expensive and produces stronger, more durable memory traces. Study methods that rely only on recognition (re-reading, highlighting) create fluency illusions without building durable access.2. Why does spaced practice outperform massed practice (cramming) for long-term retention?
Show answer
Spaced practice forces retrieval at increasing intervals, which strengthens memory traces each time. Cramming produces short-term recall that decays within days because memories are not consolidated through repeated retrieval. The spacing schedule: review at Day 1, 3, 7, 14, and 30 after first learning.3. What is the blank-page protocol and when should you use it?
Show answer
After studying a topic: (1) Close all sources, (2) set a timer for 5 minutes, (3) write everything you know about the topic, (4) open sources and compare — mark what you missed. The misses become your next study targets. Use it after any reading session to convert passive exposure into active retrieval.4. What is elaboration as a learning technique, and give one example?
Show answer
Elaboration means connecting new information to things you already know by asking "why does this work?", "how is this like something I know?", or "when would this break?". Example: instead of memorizing that kubectl rollout restart restarts pods, understand WHY — it triggers a new ReplicaSet with an updated pod template hash. More connections create more retrieval routes.5. What is the core principle of spaced repetition systems like Anki?
Show answer
Anki presents cards at increasing intervals based on your recall strength: easy cards are shown rarely (weeks or months apart), hard cards are shown frequently (daily or every few days). This matches the forgetting curve — you review just before you would forget, which reinforces the trace at the optimal moment. The scheduling is automatic, but the principle works with any calendar-based manual system too.🟡 Medium (6)¶
1. What are three signs that a fluency illusion is tricking you into overestimating mastery?
Show answer
(1) You feel you "know it" while looking at the material but cannot reproduce it with the source closed. (2) Re-reading your notes feels productive but you cannot recall them later. (3) You can recognize the correct answer in multiple-choice but cannot generate it from scratch. The test: close the source and write what you know — gaps reveal the illusion.2. Why does interleaving different topics in one study session produce better results than blocking one topic at a time?
Show answer
Interleaving forces the brain to discriminate between topics ("Is this a networking issue or a permissions issue?"), building exactly the retrieval skills needed in real situations. Blocked practice lets you use context as a cue (you know the answer is about DNS because you are studying DNS). Interleaving feels harder and slower but produces dramatically better long-term retention.3. What is desirable difficulty and why does easy study feel productive but encode weakly?
Show answer
Desirable difficulty is the principle that making learning harder in specific ways (self-testing, spacing, interleaving, generating answers before seeing them) produces more durable encoding despite feeling slower. Easy study (re-reading, highlighting) creates familiarity without recall strength. The discomfort of retrieval failure IS the signal that learning is happening — it is not a sign to switch to easier methods.4. How should an error log be structured and used to improve learning?
Show answer
An error log has three columns: (1) What I missed — the specific fact or concept, (2) Why I missed it — fact gap, conceptual confusion, or procedural mistake, (3) What I will test next — a specific retrieval exercise. Review it weekly to find patterns revealing systemic weaknesses. A repeated error after review needs a different encoding strategy, not just more repetition.5. Why is memory described as context-sensitive, and what are the practical implications for study?
Show answer
Memory is retrieved via cues — the environment, mental state, and associated concepts present at encoding. Studying only in one location or mental state creates cue-dependent memories that are harder to access in different contexts (like an interview or incident). Vary your study locations, interleave topics, and practice retrieval in conditions different from where you studied to make memories more portable.6. What distinguishes deliberate practice from regular practice, and why do most people plateau?
Show answer
Deliberate practice has four requirements: 1) Specific goals — focus on a defined sub-skill, not general improvement. 2) Full concentration — no autopilot or multitasking. 3) Immediate feedback — know whether you got it right. 4) Discomfort — working at the edge of your ability, not in the comfort zone. Most people plateau because they practice what they already know (comfortable repetition) rather than isolating and drilling weaknesses. Ten years of experience can be one year repeated ten times.🔴 Hard (3)¶
1. What are the three levels of transfer in learning, and what does each require?
Show answer
Level 1 (Near transfer): same tool, different problem — e.g., writing a StatefulSet after learning Deployments. Level 2 (Conceptual transfer): same principle, different domain — e.g., seeing IaC and K8s declarative config as the same pattern. Level 3 (Far transfer): abstract pattern applied to a new field — e.g., recognizing reconciliation loops in K8s as eventual consistency from databases. Far transfer requires synthesis and analogy exercises.2. What is the recommended time allocation for a balanced learning pipeline, and why is more than 50% input time a sign of a broken pipeline?
Show answer
Recommended allocation: 40% input (reading/watching), 20% processing (summarize, elaborate, connect), 10% storing (flashcards, notes), 30% retrieving (closed-book testing, spaced review). Spending more than 50% on input means you are running a leaky bucket — material enters but is never consolidated through retrieval. Flip the ratio: more time on retrieval and processing than on passive input.3. What is the Feynman Technique and why does teaching expose gaps that passive study misses?
