質問 # 20
An infrastructure admin is troubleshooting a Portworx node that is down.
What should be run first to check the Kubernetes cluster status?
正解：C
解説：
Comprehensive and Detailed Explanation From Exact Extract:
When troubleshooting a Portworx node that appears down, the first step is to verify the overall Kubernetes cluster health, particularly the node's readiness. Running kubectl get node -o wide provides detailed information about all cluster nodes, including their status, roles, and network details. Ensuring the affected node is marked "Ready" or identifying any abnormal conditions helps isolate whether the problem is at the Kubernetes level or specific to Portworx. If the node is not Ready, issues may lie with Kubernetes components or node-level hardware/network problems. After confirming node status, further investigation using pxctl status or examining kubelet logs with journalctl can pinpoint Portworx-specific or system-level failures. Portworx operational best practices recommend starting with Kubernetes node health checks before delving into Portworx or system logs to effectively triage issues【Pure Storage Portworx Troubleshooting Guide source】.
質問 # 21
What happens if the spec.csi.enabled flag is set to false in the Portworx StorageCluster spec?
正解：A
解説：
Comprehensive and Detailed Explanation From Exact Extract:
The spec.csi.enabled flag in the Portworx StorageCluster specification dictates whether the Container Storage Interface (CSI) driver is deployed within the Kubernetes environment. Setting this flag to false means that the CSI driver will not be installed or enabled, effectively disabling the CSI functionality. The CSI driver is responsible for dynamic volume provisioning, attachment, and lifecycle management in Kubernetes clusters. Disabling CSI might be necessary in environments relying on legacy volume plugins or specific operational requirements. When CSI is disabled, Portworx will not support dynamic provisioning or other CSI-dependent features, which could limit functionality for Kubernetes storage operations. Portworx operator documentation explicitly states that disabling CSI omits the CSI driver installation, advising users to carefully consider the impact before setting this flag to false, especially in production environments requiring CSI functionality【Pure Storage Portworx Operator Docs source】.
質問 # 22
When is a volume considered "Public"?
正解：B
解説：
Comprehensive and Detailed Explanation From Exact Extract:
In Portworx, a volume is considered "Public" when guest access is enabled. Guest access allows users and applications without explicit Portworx authentication credentials to access the volume. This setting is typically used in less restrictive environments where access control is relaxed, but it reduces security by exposing data to potentially unauthorized entities. Public volumes can be accessed by any entity with network connectivity and basic permissions, which is why enabling guest access is carefully controlled in secure deployments. Portworx documentation on security models and access controls stresses that public volumes should be used sparingly and monitored closely due to the elevated risk of data exposure and compliance violations【Pure Storage Portworx Security Guide source】.
質問 # 23
What is the minimum number of cores needed to run Portworx?
正解：B
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Portworx requires a minimum of 4 CPU cores per node to operate efficiently. This minimum ensures sufficient compute resources to handle storage management operations, volume I/O, replication, and metadata services without performance bottlenecks. While more cores can improve throughput and scalability, 4 cores is the documented baseline for supporting production workloads and maintaining cluster responsiveness. The Portworx system requirements specify this CPU baseline to guarantee stable operation alongside other Kubernetes node workloads. Deployments with fewer CPU resources may face degraded performance or instability. Official Portworx hardware requirements recommend 4 cores or more per node to meet performance and reliability objectives in typical enterprise environments【Pure Storage Portworx System Requirements source】.
質問 # 24
If a Portworx node is down and the Kubernetes cluster is healthy, which command should be used to check Portworx alerts on a healthy node?
正解：A
解説：
Comprehensive and Detailed Explanation From Exact Extract:
To check Portworx-specific alerts on a healthy node, administrators use the command pxctl alerts show. This command displays current alerts raised by Portworx, including warnings and critical notifications about storage, nodes, and cluster health. Even if one node is down, alerts from the healthy nodes can provide insights into cluster-wide issues or the status of the affected node. While journalctl displays system and service logs and kubectl describe node shows Kubernetes node info, neither provides aggregated Portworx alert data. The Portworx observability documentation recommends using pxctl alerts show for focused monitoring and alert management, enabling administrators to respond effectively to operational events within the Portworx cluster【Pure Storage Portworx Monitoring Guide source】.
