Correct answer & explanation
✓
A log sink with BigQuery as the destination
Log sinks are used to route logs to destinations like BigQuery, Cloud Storage, or Pub/Sub.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
An alerting policy with a log-based trigger
Why it's wrong here
An alerting policy with a log-based trigger is designed to notify you when specific conditions are met in incoming log entries; it can create incidents or send notifications via Cloud Monitoring. It does not route or copy log entries to any external destination. Exporting logs requires a log sink, not an alerting or notification configuration.
- ✗
A log-based metric
Why it's wrong here
A log-based metric computes a numeric value such as a counter or distribution from your log entries and stores that metric in Cloud Monitoring, enabling charts and alerts. It does not persist the raw log data itself, nor does it move the content to BigQuery. To get logs into BigQuery, you need a sink that writes matching entries to a BigQuery dataset.
- ✗
An export job in BigQuery
Why it's wrong here
An export job in BigQuery extracts data from BigQuery tables to formats like Parquet, CSV, or Avro, usually to Cloud Storage. It is an outbound operation, not an import mechanism, and BigQuery has no built-in 'export job' that pulls Cloud Logging data. Incoming logs must be delivered through a log router sink that writes directly to a BigQuery destination.
- ✓
A log sink with BigQuery as the destination
Why this is correct
A log sink with BigQuery as the destination is the correct method: Cloud Logging's log router matches your chosen log entries and delivers them to a BigQuery dataset, where each daily collection becomes a table. You configure the destination by providing a dataset name, and the sink automatically handles batching and streaming writes. This is the officially supported, commonly used way to export logs to BigQuery for analytics.
