Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Telemetry data collection including latency, error rates, and request volume metrics
Why this is correct
Correct. Envoy proxies automatically collect and export rich telemetry metrics.
- ✓
Access control policies to restrict which services can communicate with each other
Why this is correct
Correct. Fine-grained authorization policies control service access.
- ✓
Automatic mutual TLS (mTLS) encryption for in-transit pod-to-pod communication
Why this is correct
Correct. Service mesh enforces mTLS for all service communications.
- ✗
Direct hardware firewall ACL programming on physical Oracle Exadata rack switches
Why it's wrong here
Incorrect. Service mesh operates at the application/proxy layer, not physical switch ACLs.
- ✗
Automatic translation of Oracle Database PL/SQL stored procedures into REST APIs
Why it's wrong here
