NPP4考试与NPP3大部分题型是重合的,在考NPP4时可以结合NPP3题库一起考试
01.  What are themain functional areas of NCC? (Choose three.)   234
  • Filemanagement
  • Cluster info
  • health checks
  • Fault Analysis
  • Storagemanagment

02.  How does aNutanix cluster process a read request from a guest VM, if there is no localcopy of the data? (Choose two.)   35
  • TheController VM forwards the request to the hypervisor; the hypervisor forwardsthe request to the nearest host that contains the data
  • TheController VM searches all HOT Cache data across the network; if the data doesnot reside in HOT Cache, the controller obtains a copy from the nearest host
  • Remotedata is migrated to the local host, so future read requests are local
  • Remotedata is migrated to HOT Cache on the remote host to maximize performance
  • TheController VM reads across the network to obtain a copy of the data from aremote node

03.  Assume that a VMwas failed over to a new host due to a node failure. How does the Nutanixcluster handle the VM's I/O if the data is stored on a node other than the VM'snew host?  3
  • Onlywrite requests are sent across the network to the new VM host
  • Allread and write requests are suspended until the data is migrated to the currenthost
  • Write requests stilloccur locally on the new local host and read requests can come from thelocalhost unless needed to traverse network.
  • Allwrite requests are sent across the network to the new VM host, and readrequests are suspended until the data is migrated locally

04.  What is onemethod to manage the storage performance characteristics on a Nutanix cluster?   3
  • Increasethe number of guest VMs in each cluster
  • Seta storage reservation when creating a container
  • Direct all initial read requests to the HOTCache
  • Limiteach cluster to a single VM guest, each having its own Nutanix Controller VM

Which of the following accurately describes the NOS version requirement for Controller VMs in a Nutanix Cluster?
All CVMs in a Nutanix Cluster must run the same major release number (e.g. 3.x) while their minor release number (e.g. 3.5) can differ

Which steps should be taken after the installation and configuration of the cluster have finished? (Choose two)

How does the Nutanix system respond if a single Controller VM Stargate process fails to respond? (Choose two.)
Guest VMs on the host with the failed Stargate will experience little or no performance degradation.
Guest VMs on the host with the failed Stargate may appear to hang until the storage path is restored. After the storage path is redirected, users will experience little or no performance degradation.
Guest VMs on the host with the failed Stargate will appear to hang. There is also a very high probability that some VM data extents will be missing completely, until the Controller VM resumes operation.
