What is the primary purpose of Stork in a Kubernetes cluster?
A. To manage storage operations and migrations.
B. To deploy applications automatically.
C. To monitor network traffic.
正解：A
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Stork (Storage Orchestrator for Kubernetes) is a Portworx component designed to enhance Kubernetes storage management. Its primary purpose is to orchestrate storage-aware operations, including volume scheduling, migration, backup, and disaster recovery. Stork integrates deeply with Kubernetes to provide application-aware scheduling decisions that respect storage constraints such as volume locality and affinity. It also facilitates migration of stateful workloads by coordinating volume replication and failover. Stork simplifies complex storage workflows in Kubernetes environments, enabling seamless backup and restore of applications and improving overall resilience. Portworx's official documentation highlights Stork as a key enabler for business continuity by managing storage operations and migrations, making it essential for Kubernetes environments running critical stateful workloads with Portworx storage【Pure Storage Portworx Stork Guide source】.
質問 # 29
What is the minimum kernel needed for Portworx?
A. Kernel version 4.15 or greater
B. Kernel version 3.10 or greater
C. Portworx works with any kernel
正解：B
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Portworx requires a minimum Linux kernel version of 3.10 or greater to operate properly. This requirement stems from Portworx's dependencies on certain kernel features and modules that became standard from kernel version 3.10 onwards. The kernel version affects support for device-mapper, overlay filesystems, network stack enhancements, and other low-level capabilities essential for Portworx's block storage functionality and performance. Although newer kernels (like 4.15+) offer additional features and improvements, Portworx maintains compatibility back to 3.10 to support a wide range of enterprise Linux distributions such as RHEL, CentOS, and Ubuntu LTS releases. The official Portworx system requirements document explicitly states kernel 3.10 as the minimum supported version to ensure stability and compatibility in production environments【Pure Storage Portworx System Requirements source】.
質問 # 30
Which CRD object can be used to restore an existing ApplicationBackup?
A. Migration
B. ApplicationRestore
C. VolumeSnapshot
正解：B
解説：
Comprehensive and Detailed Explanation From Exact Extract:
The ApplicationRestore Custom Resource Definition (CRD) object in Portworx is specifically designed to restore an application from an existing ApplicationBackup. This object orchestrates the process of recovering a consistent snapshot of an application, including all its associated volumes, in Kubernetes environments. Using ApplicationRestore, administrators can define the source backup, restore location, and any necessary transformations during restoration. This facilitates disaster recovery, migration, or rollback scenarios for complex stateful applications. The Portworx backup and restore documentation clearly defines ApplicationRestore as the controller responsible for application-level recovery operations, ensuring data integrity and consistency throughout the restore workflow【Pure Storage Portworx Backup and Restore Guide source】.
質問 # 31
Which command could be used to install Portworx on Kubernetes using the PX-Operator?
A. kubectl apply -f "https://install.portworx.com/<portworx_version>?operator=true&mc=false&kbver=1.25.0&ns=portworx&b=true&kd=type%3Dgp3%2Csize%3D150&s=%2F%2F22type%3Dgp3%2Csize%3D150&c=px-cluster-0584f7fl-b6be-4608-800c-2ac5fb8069e0&stork=true&csi=true&mon=true&tel=false&st=k8s&promop=true"
B. kubectl apply -f "https://install.portworx.com/<portworx_version>?comp=pxoperator&kbver=<k8s-version>&ns=portworx"
C. curl -O px-ag-install.sh -L "https://install.portworx.com/$PXVER/air-gapped?kbver=$KBVER"
正解：B
解説：
Comprehensive and Detailed Explanation From Exact Extract:
The officially recommended method to install Portworx with Kubernetes Operator support is using the PX-Operator manifest. This is done by applying the manifest URL with the comp=pxoperator parameter. The command:
kubectl apply -f "https://install.portworx.com/<portworx_version>?comp=pxoperator&kbver=<k8s-version>&ns=portworx" deploys the Portworx Operator, which manages Portworx lifecycle operations such as installation, upgrades, and configuration changes within the Kubernetes cluster. Specifying the Kubernetes version (kbver) and namespace (ns) ensures compatibility and proper scoping. This operator-centric installation enables more efficient management and automation compared to standalone scripts or manual installations. Portworx official operator installation documentation confirms this approach as the best practice for production deployments, streamlining Portworx management in Kubernetes environments【Pure Storage Portworx Operator Installation Guide source】.
質問 # 32
What is a key benefit of using on-demand snapshots in a Kubernetes environment with Portworx?
A. They provide immediate data recovery options without stopping applications.
B. They require no additional configuration after the initial setup.
C. They automatically scale storage capacity.
正解：A
解説：
Comprehensive and Detailed Explanation From Exact Extract:
On-demand snapshots in Portworx allow administrators and applications to create point-in-time copies of volumes instantly without requiring downtime or interrupting running workloads. This capability is critical in Kubernetes environments where high availability and continuous operation are mandatory. Snapshots capture the exact state of data at a moment, enabling rapid recovery from accidental deletion, corruption, or ransomware attacks. Since these snapshots are created live, applications continue to run seamlessly, ensuring minimal impact on user experience. Portworx's snapshot technology uses efficient -on-write mechanisms, which also minimize storage overhead. Official Portworx documentation emphasizes that on-demand snapshots enhance data protection strategies by enabling quick backups and restores without requiring maintenance windows or complex scheduling【Pure Storage Portworx Snapshot Guide source】.
