gcp-pde-guid Study Guide + Practice
Short notes + common traps + quick practice. Then validate with the mini test.
Quick answers
- Read notes → do 10 questions → review mistakes immediately.
- Write 1 rule per mistake (symptom → cause → fix / concept → example).
- Repeat within 24–48 hours to lock it in.
- When accuracy is stable, switch to timed simulator practice.
This PDE guide covers the first big decision in data engineering scenarios: batch vs streaming, and how pipelines flow from ingestion to processing to storage.
Fast mental model: batch = periodic processing, streaming = near-real-time events. Choose based on latency requirements and data freshness.
Do the mini quiz to validate. Then continue in PrepMaster for offline packs and explanations.

- Batch vs streaming: latency vs complexity tradeoff (high-level)
- Ingestion vs processing vs storage: pipeline stages
- Common scenario cues: near-real-time alerts → streaming; daily reports → batch
- Reliability basics: retries, dead-letter concept, idempotency idea (high-level)
- Trap: choosing streaming when batch meets the requirement (cost/complexity)

Frequently Asked Questions
What’s the simplest batch vs streaming rule?
If you need seconds/minutes latency, think streaming. If minutes/hours/day is ok, batch is often simpler and cheaper.
Why do scenario questions focus on pipeline stages?
Because the exam tests architecture choices: how data moves, transforms, and is stored.
