The NKPA course details the process of creating an NKP cluster on vSphere using the NKP CLI, including the configuration of multiple node pools with specific worker node counts and CPU settings. The correct approach involves creating the cluster with the initial node pool and then adding additional node pools separately.
The steps in Option A align with this process:
* nkp create cluster vsphere --worker-replicas 6 --worker-cpus 10: This command creates the NKP cluster on vSphere with the first node pool, consisting of 6 worker nodes, each with 10 CPUs.
* nkp create nodepool vsphere --worker-replicas 3 --worker-cpus 8: This adds the second node pool to the cluster with 3 worker nodes, each with 8 CPUs.
* nkp create nodepool vsphere --worker-replicas 3 --worker-cpus 6: This adds the third node pool with 3 worker nodes, each with 6 CPUs.
The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: "To create an NKP cluster with multiple node pools on vSphere, use nkp create cluster vsphere to define the first node pool, then add additional node pools with nkp create nodepool vsphere, specifying --worker-replicas and --worker-cpus for each pool." This method ensures precise control over each node pool's configuration.
Incorrect Options:
* B: The second nkp create nodepool command uses --replicas and --cpus, which are not the correct flags.
The NKPA course specifies --worker-replicas and --worker-cpus.
* C: The --node-pools, --worker-replicas 6,3,3, and --worker-cpus 10,8,6 flags are not supported in a single nkp create cluster command. Node pools must be created separately.
* D: There is no nkp create nodepools command; the correct command is nkp create nodepool.
Additionally, --replicas and --cpus are incorrect flags.
