質問 # 224
If kubectl is failing to retrieve information from the cluster, where can you find Pod logs to troubleshoot?
正解：A
解説：
The correct answer is A: /var/log/pods/. When kubectl logs can't retrieve logs (for example, API connectivity issues, auth problems, or kubelet/API proxy issues), you can often troubleshoot directly on the node where the Pod ran. Kubernetes nodes typically store container logs on disk, and a common location is under /var/log
/pods/, organized by namespace, Pod name/UID, and container. This directory contains symlinks or files that map to the underlying container runtime log location (often under /var/log/containers/ as well, depending on distro/runtime setup).
Option B (~/.kube/config) is your local kubeconfig file; it contains cluster endpoints and credentials, not Pod logs. Option D (/etc/kubernetes/) contains Kubernetes component configuration/manifests on some installations (especially control plane), not application logs. Option C (/var/log/k8s/) is not a standard Kubernetes log path.
Operationally, the node-level log locations depend on the container runtime and logging configuration, but the Kubernetes convention is that kubelet writes container logs to a known location and exposes them through the API so kubectl logs works. If the API path is broken, node access becomes your fallback. This is also why secure node access is sensitive: anyone with node root access can potentially read logs (and other data), which is part of the threat model.
So, the best answer for where to look on the node for Pod logs when kubectl can't retrieve them is /var/log
/pods/, option A.

質問 # 227
Which of the following is a definition of Hybrid Cloud?
正解：D
解説：
A hybrid cloud architecture combines public cloud and private/on-premises environments, often spanning multiple infrastructure domains while maintaining some level of portability, connectivity, and unified operations. Option C captures the commonly accepted definition: services run across public and private clouds, including on-premises data centers, so C is correct.
Hybrid cloud is not limited to a single cloud provider (which is why A is too restrictive). Many organizations adopt hybrid cloud to meet regulatory requirements, data residency constraints, latency needs, or to preserve existing investments while still using public cloud elasticity. In Kubernetes terms, hybrid strategies often include running clusters both on-prem and in one or more public clouds, then standardizing deployment through Kubernetes APIs, GitOps, and consistent security/observability practices.
Option B is incorrect because excluding data centers in different availability zones is not a defining property; in fact, hybrid deployments commonly use multiple zones/regions for resilience. Option D is a distraction:
serverless inclusion or exclusion does not define hybrid cloud. Hybrid is about the combination of infrastructure environments, not a specific compute model.
A practical cloud-native view is that hybrid architectures introduce challenges around identity, networking, policy enforcement, and consistent observability across environments. Kubernetes helps because it provides a consistent control plane API and workload model regardless of where it runs. Tools like service meshes, federated identity, and unified monitoring can further reduce fragmentation.
So, the most accurate definition in the given choices is C: hybrid cloud combines public and private clouds, including on-premises infrastructure, to run services in a coordinated architecture.

質問 # 228
A DevOps engineer must ensure Pods in the testing namespace cannot run with elevated privileges. Which action correctly enforces this restriction?
正解：D
解説：
Pod Security Admission enforces Pod Security Standards at the namespace level. Applying the restricted enforcement profile to the testing namespace prevents privileged containers and other unsafe privilege-escalation settings.
