Which of the following is a benefit of using a service mesh?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enhanced observability and traffic control
A service mesh provides observability (metrics, tracing), traffic management (routing, load balancing), and security (mTLS) without requiring changes to application code. It does not directly manage storage or scaling.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Simplified storage management
Why it's wrong here
Service mesh does not deal with storage; that is handled by CSI drivers.
- ✗
Automatic scaling of applications
Why it's wrong here
Scaling is handled by HPA or KEDA, not service mesh.
- ✓
Enhanced observability and traffic control
Why this is correct
Service mesh provides detailed observability and traffic management features.
- ✗
Direct database access
Why it's wrong here
Service mesh does not provide database access; it handles inter-service communication.
