Labs

Browser-local teaching labs

Six reproducible exercises run in this browser. They show steps, results, data tables, and charts from synthetic inputs; none provisions Azure resources or claims benchmark measurements.

Compute · AZ-104 / AZ-305

Compute workload capacity worksheet

Estimate planning cores and replicas from synthetic RPS, service time, cores, and headroom; no Azure performance claim.

Includes steps, formulas, limitations, source links, result table, and accessible SVG chart.

Storage · AZ-104 / AZ-305

Storage recovery timeline checker

Compare RPO/RTO targets, backup age at incident, and illustrative recovery phases; reinforces that replication is not backup.

Includes steps, formulas, limitations, source links, result table, and accessible SVG chart.

Network · AZ-700 / AZ-305

Azure IPv4 subnet capacity lab

Validate prefix, total addresses, five Azure-reserved addresses, and usable addresses; Azure IPv4 only.

Includes steps, formulas, limitations, source links, result table, and accessible SVG chart.

Database · AZ-305

Database partition-skew simulation

Generate original synthetic records and show actual bucket counts for both constant and spread keys.

Includes steps, formulas, limitations, source links, result table, and accessible SVG chart.

AI · Extended learning

AI retrieval metric toy lab

Use a tiny original English corpus to show Recall@k changes with k; not an Azure AI Search, vector, or LLM-quality benchmark.

Includes steps, formulas, limitations, source links, result table, and accessible SVG chart.

ML · Extended learning

ML confusion-matrix calculator

Compute named metrics from integer TP/FP/FN/TN counts and show the count chart.

Includes steps, formulas, limitations, source links, result table, and accessible SVG chart.
