Practice Calibration
Use this after attempting independent practice. These are calibration notes for the new cases, not answers to every original open-ended project. The module assessment retains its own scoring and evidence requirements.
Prerequisite calibration
Inspect the actual listener, target address/port and client failure; do not infer from a filename or service label. Repair S05 sockets and process evidence.
A ready answer includes the example or trace requested in the entry check. A memorized term is not sufficient. Repair the named earlier skill, then change the example and explain it without this page.
Case A
Startup gating permits initialization; readiness controls eligibility for traffic; liveness addresses a restart-worthy failure. One dependency outage should not automatically trigger a restart loop.
Full practice credit requires the result, assumptions and an explanation of the tempting error. A correctly guessed conclusion without those elements is only partial evidence.
Case B
A PDB concerns voluntary eviction, not every rollout or involuntary failure. Inspect deployment rollout settings, resources, readiness and current endpoints.
The key judgment is which guarantee survives the changed condition. Do not transfer a result from the first case without checking that condition.
Experiment calibration
Use the actual cluster lab with normal traffic, bad-image/slow-start/storage failures and allowed/denied network controls. A cluster accepting policy YAML without an enforcing plugin is not proof of isolation.
A usable record links the hypothesis to the actual input, observation and interpretation. The negative control must fail for the intended reason, and the repaired setup must pass the relevant check again. Report unexpected outcomes rather than altering the hypothesis afterward. Explicitly state the model, environment and untested boundary; passing a small fixture never proves every deployment behavior.
Recheck
Explain a fresh variant without the key. Retain the original error, repair, help received and delayed result in the existing evidence packet. Self-calibration is not an independent reviewer sign-off or a learner-pilot result. For retrieval-question explanations, use quiz calibration only after attempting the quiz.
