In Portworx, managing credentials for cloud object stores is vital to enable features like cloud snapshots and backups. The command pxctl credentials create is used to create and register cloud credentials with the Portworx cluster. This command allows administrators to specify provider details such as AWS, Google Cloud, or Azure, and input necessary access keys, secret keys, regions, and endpoints. Proper credential configuration enables Portworx to authenticate with external object stores securely, ensuring reliable data movement and disaster recovery operations. The CLI facilitates easy credential management, including listing, updating, and deleting credentials as needed. Official Portworx documentation highlights pxctl credentials create as the authoritative command for establishing cloud storage access, ensuring security best practices by managing credentials centrally within the Portworx control plane?Pure Storage Portworx CLI Guide†source?.

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 manifests?Pure Storage Portworx StorageClass Guide†source?.

The StorageCluster Custom Resource Definition (CRD) is the central object used to configure and manage a Portworx installation on Kubernetes. It contains essential parameters including cluster-wide settings, KVDB configuration, storage pool definitions, security options, and CSI driver configurations. The StorageCluster resource declaratively defines how Portworx should be deployed, upgraded, and operated within the Kubernetes cluster. Administrators edit this object to adjust configurations, enabling features like telemetry, monitoring, and cloud integration. Unlike VolumeSnapshot (which manages snapshots) or ServiceAccount (which controls Kubernetes permissions), StorageCluster governs the overall lifecycle and parameters of the Portworx deployment. Portworx operator documentation identifies StorageCluster as the fundamental CRD for installation and configuration management?Pure Storage Portworx Operator Guide†source?.
