After configuring credentials for AWS S3 object storage, the administrator uses the command pxctl cloudsnap backup <volumename> -cred-id <credentials-name> to create a cloud snapshot backup of a Portworx volume. This command instructs Portworx to take a point-in-time snapshot of the specified volume and upload it securely to the configured S3 bucket using the referenced credentials. The command leverages Portworx's cloud snapshot feature for disaster recovery and long-term retention. Option B relates to creating credentials and is not the backup command. Option C creates a local snapshot but does not back it up to the cloud. The Portworx CLI documentation highlights pxctl cloudsnap backup as the core method to perform backups to cloud object storage, enabling data protection strategies aligned with cloud-native architecturesPure Storage Portworx Cloud Snapshot Guidesource.

To create a StorageClass in Kubernetes for Portworx volumes that are encrypted and replicated twice, the correct parameters are encrypted: 'true' to enable encryption and repl: '2' to specify two replicas. Option A accurately sets these parameters, ensuring volumes provisioned with this StorageClass will be encrypted at rest and maintain two replicas for data redundancy. Option B uses sharedv4: 'true', which relates to NFS-like sharing, not encryption. Option C uses secure: 'true', which is not the recognized parameter for enabling encryption in Portworx StorageClass definitions. The official Portworx StorageClass parameter documentation confirms encrypted as the correct flag for encryption and repl to specify replication factor, enabling administrators to enforce data security and availability policies declaratively through Kubernetes manifestsPure Storage Portworx StorageClass Guidesource.

Portworx primarily relies on Direct Attached Storage (DAS) for its storage provisioning. DAS refers to physical disks or SSDs directly connected to the nodes running Portworx. Using DAS enables high-performance, low-latency access to storage resources, crucial for stateful containerized applications. Portworx aggregates and abstracts these local devices into distributed storage pools, providing features like replication, encryption, and snapshots. While Portworx integrates with Object Storage for cloud snapshots and disaster recovery, and can support NFS for certain use cases, the core storage provisioning and volume management depend on DAS. The Portworx architecture documentation clarifies that leveraging local node storage is essential for delivering performant, resilient, and scalable persistent storage in Kubernetes environmentsPure Storage Portworx Architecture Guidesource.

Labeling Kubernetes nodes with rack information is achieved using the kubectl label nodes command. The syntax would be something like kubectl label nodes <node-name> px/rack=<rack-identifier>. This label allows Portworx to understand the physical or logical topology of nodes, enabling placement strategies that optimize data locality, fault tolerance, and availability based on rack awareness. Taints and annotations serve different purposes; taints affect pod scheduling by repelling pods, while annotations provide metadata without influencing scheduling. Portworx uses node labels extensively for topology-aware volume placement and disaster recovery planning. Official Portworx documentation recommends labeling nodes with topology identifiers like rack or zone to enable advanced placement strategies and maintain application resiliency in distributed environmentsPure Storage Portworx Placement Guidesource.

To view current alerts raised by Portworx within the cluster, the primary command is pxctl alerts show. This CLI command lists all active alerts with details such as severity, affected resources, and timestamps. It helps administrators quickly identify issues impacting cluster health, storage pools, volumes, or nodes. While Grafana is a powerful visualization tool often used alongside Prometheus for monitoring, it requires additional setup and does not directly replace the immediate, real-time alert query functionality of pxctl. The pxctl cd list alerts is not a valid command. Portworx documentation emphasizes pxctl alerts show as the go-to tool for alert inspection during operational checks and troubleshooting, offering a concise and focused alert view integrated with Portworx's internal alerting systemPure Storage Portworx Alerting Guidesource.
