問題文

An architect draws the platform as four stacked layers and labels them hardware, virtualization, container platform, and orchestration. A reviewer asks which layer decides how many replicas of a containerized workload run. Which layer is it?

選択肢

1. The hardware layer decides it because the physical server exposes a fixed number of slots for the workload.
2. The orchestration layer decides it because the descriptor is re-read on a timer and the difference is applied.
3. The virtualization layer decides it because the hypervisor counts the running processes and starts the missing ones.
4. The container platform layer decides it because the declared replica count is reconciled by a controller inside that layer.
