Free Google Cloud Architect Actual Exam Questions - Question 3 Discussion
application using the `gcloud` CLI, but you want to test it before routing all traffic to
it. Which command is appropriate?
D imo, because --no-promote avoids routing traffic right away.
D/C? D looks right because --no-promote lets you deploy without shifting traffic immediately. C doesn’t even seem like a valid command for App Engine, so it’s probably out.
I’m with that, B seems best. Directly writing to BigQuery (C) wouldn’t scale well for 20 million vehicles streaming so much data every second. FTP (D) is obviously outdated for real-time ingestion. GCS (A) could work but it’s more for batch or object storage, not real-time streams. Pub/Sub handles massive streaming loads and decouples ingestion from processing, which fits the scale here.
B tbh makes the most sense since Pub/Sub can handle huge volumes of streaming data and acts as a buffer before processing. But does the case study mention anything about network reliability or vehicle connectivity? That could affect whether direct streaming is feasible or if you’d need some edge caching first. Also, is there a requirement for real-time analytics or just batch processing? That might rule out some options too.
