KCSA Overview OF Cloud Native Security Practice Question
An administrator is auditing a managed Kubernetes service (such as Amazon EKS, Google GKE, or Azure AKS) to verify compliance with cloud native security principles. The administrator attempts to SSH directly into the underlying worker node to inspect system logs. The connection is refused. Why is this restriction expected under the cloud native security model?
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
✓
The cloud provider abstracts and manages the underlying Cloud layer, prohibiting direct node access to maintain infrastructure integrity.
In managed Kubernetes offerings, the cloud provider manages the underlying virtual machines and restricts direct SSH access to ensure immutable infrastructure and proper separation of responsibilities in the Cloud layer.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The cloud provider abstracts and manages the underlying Cloud layer, prohibiting direct node access to maintain infrastructure integrity.
Why this is correct
Managed Kubernetes services abstract the Cloud layer infrastructure, enforcing management via the Kubernetes API rather than direct OS access.
- ✗
The kubelet has been disabled by the cloud provider for security compliance.
Why it's wrong here
The kubelet must remain running for the node to function in the cluster.
- ✗
Container runtime security policies have blocked the SSH daemon process.
Why it's wrong here
SSH runs as a host-level system service, not inside a container runtime.
- ✗
NetworkPolicies applied to the kube-system namespace have dropped incoming port 22 traffic.
Why it's wrong here
Network policies apply to pod-to-pod communication, not host operating system daemons like SSH.
