CloudWatch Logs Insights query:
fields @timestamp, @message
| filter @message like /ERROR|WARN/
| sort @timestamp desc
| limit 20

Correct answer & explanation
✓
Retrieve the 20 most recent log events that contain 'ERROR' or 'WARN'.
The query filters log events containing 'ERROR' or 'WARN', sorts them by timestamp descending, and returns the 20 most recent. Option A is correct. Option B is wrong because it returns both ERROR and WARN. Option C is wrong because it does not count them. Option D is wrong because it does not group by log level.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
