Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Easier to read for humans
Why it's wrong here
While JSON’s key-value structure can be human-readable, the scenario’s requirement is enabling *better querying* at scale, not readability. Unstructured plain-text logs lack a consistent schema, so automated tools cannot parse fields like `timestamp` or `error_code` without complex regex. Human readability is the actual purpose of plain-text logs in small-scale debugging, where a developer reads a single file directly rather than querying a centralised log aggregator.
- ✓
Enables querying specific fields
Why this is correct
Structured logs allow field-level queries.
- ✗
Reduced storage costs
Why it's wrong here
JSON logs can be larger due to keys.
- ✗
Faster log ingestion
Why it's wrong here
Ingestion speed depends on backend, not format.
