Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Zero-trust network architecture
Why it's wrong here
Capabilities govern kernel access, not network segmentation.

Why this is correct
Containers should run with minimal privileges; `CAP_SYS_ADMIN` grants broad root-like privileges.
- ✗

Why it's wrong here
Shared responsibility defines division of labor between provider and customer, not pod capabilities.

Why it's wrong here
Ephemeral design relates to workload lifecycle, not capability grants.
