During a load test, the test tool reports a 5% error rate. The team needs to determine if the response time data is still valid for analysis. What is the most important consideration?

Discard all response time data because any error rate above 0% invalidates the test

Re-run the test until the error rate is exactly 0% before analyzing any data

Ignore the errors because a 5% error rate is considered acceptable in most performance tests

Determine whether the errors are functional failures or timeouts, and whether they are evenly distributed or concentrated in specific transactions
