Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
trafficPolicy.connectionPool.tcp.maxConnections
Why this is correct
This field specifically governs the maximum concurrent TCP connections.
- ✗
trafficPolicy.connectionPool.http.maxRequests
Why it's wrong here
This limits concurrent HTTP requests, not TCP connections.
- ✗
trafficPolicy.circuitBreaker.maxConnections
Why it's wrong here
CircuitBreaker is a field within trafficPolicy, but it does not have a direct maxConnections child.
- ✗
trafficPolicy.outlierDetection.maxConnections
Why it's wrong here
Outlier detection focuses on ejecting unhealthy hosts, not connection limits.
- ✗
trafficPolicy.loadBalancer.maxConnections
Why it's wrong here
The loadBalancer field governs the algorithm, not connection capacity.
