Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Automatic kernel patch management for worker nodes
Why it's wrong here
Kernel patching is a node lifecycle management task, not a service mesh function.

Why this is correct
Service meshes allow operators to define rules specifying which services can communicate and invoke specific methods.

Provisioning of persistent block storage volumes
Why it's wrong here
Storage provisioning is handled by CSI storage plugins.
