Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

The 'tcp-metadata' filter.
Why it's wrong here
This filter adds metadata and is not typically associated with data buffering.
- ✓
The Envoy 'buffer' filter configuration.
Why this is correct
The buffer filter explicitly stores request data in memory, impacting performance.
- ✗
The 'outlier-detection' settings.
Why it's wrong here
Outlier detection focuses on removing unhealthy hosts.

Why it's wrong here
Circuit breaking limits concurrency but does not buffer data.
