• Question 41:

  An administrator receives several alerts indicating a Nutanix cluster is running out of memory. As a preemptive measure, the administrator wishes to try to reduce the consumed resources, if possible.

  Which two predefined views for Reporting best display potentially reclaimable resources? (Choose two.)

  A. List of Inactive VMs
  B. list of Bully VMs
  C. Memory Runway
  D. List of Overprovisioned VMs
  A. List of Inactive VMs
  D. List of Overprovisioned VMs

  ---

  Explanation/Reference:

  To display potentially reclaimable resources in a Nutanix cluster running out of memory, an administrator can use the List of Inactive VMs and List of Overprovisioned VMs predefined views for Reporting

• Question 42:

  What is the biggest benefit of the Redfish Protocol and LCM?

  A. HBA and NIC card update twice as quickly
  B. AOS and AHV update twice as quickly
  C. BMC and BIOS update twice as quickly
  D. SSD and HDD update twice as quickly
  C. BMC and BIOS update twice as quickly

  ---

  Explanation/Reference:

  The Redfish Protocol and Lifecycle Manager (LCM) provide the biggest benefit of allowing BMC and BIOS updates to be done twice as quickly as before. This is because Redfish and LCM allow for updates to be done in parallel, rather than serially, which reduces the amount of time it takes for an update to be completed.

  A. Manual
  B. Automatic
  C. Standard
  D. Quick
  C. Standard

  Which Nutanix storage service can store Petabytes of unstructured data and supports S3 APIs?

  A. DSF
  B. Files
  C. Volumes
  D. Objects
  D. Objects

  ---

  Explanation/Reference:

  Nutanix Objects is a storage service that can store petabytes of unstructured data and supports S3 APIs.

• Question 45:

  What is the minimum number of blocks required to utilize block awareness?

  A. 2
  B. 3
  C. 4
  D. 5
  B. 3

• Question 46:

  What should an administrator do after a Protection Domain is migrated?

  A. Register Virtual Machines
  B. Restore Virtual Machines
  C. Mount datastores on Hosts
  D. Power on Virtual Machines
  C. Mount datastores on Hosts

  ---

  Explanation/Reference:

  After a Protection Domain is migrated, an administrator should mount datastores on hosts to make sure that the data is accessible by the virtual machines running on those hosts. Reference: Nutanix Certified Associate 6.5 Exam Study Guide, page 54

• Question 47:

  A single host in a four-node AHV-based cluster experiences a complete network failure.

  If more than enough resources exist in the cluster to tolerate a node failure, what happens to the user VMs running on that host?

  A. VMs remain down until network connectivity is restored.
  B. VMs stay up, but are unreachable until connectivity is restored.
  C. VMs automatically restart on the three remaining hosts.
  D. VMs are live-migrated to the three remaining hosts.
  B. VMs stay up, but are unreachable until connectivity is restored.

  ---

  Explanation/Reference:

  In the case of a single host in a four-node AHV-based cluster experiencing a complete network failure, the user VMs running on that host will stay up, but will be unreachable until connectivity is restored. This is because if more than enough resources exist in the cluster to tolerate a node failure, the VMs will continue to run, but will be unable to communicate with other nodes in the cluster due to the network failure. This is stated in the official Nutanix Certified Associate (NCA) v6.5 study guide on page 49, under the heading "Virtual Machine Availability in the Event of Node Failure".

• Question 48:

  What does Replication Factor 2 (RF2) refer to?

  A. Number of blocks that can be lost without impact
  B. Number of nodes that can be lost without impact
  C. Number of disks that can be lost in the cluster
  D. Number of copies of data written in the cluster
  D. Number of copies of data written in the cluster

  ---

  Explanation/Reference:

  Replication Factor 2 (RF2) refers to the number of copies of data written in the cluster. When RF2 is enabled, the Nutanix Distributed File System (NDFS) will create two copies of the data, resulting in higher levels of data durability and availability.

  B. Configure CHAP Authentication
  C. Reboot the VMD. Bring the disk Online
  A. Attach the Volume Group to the VM

• Question 50:

  Which tool should the administrator use to satisfy this task?

  A. aCLI
  B. Prism Element
  C. nCLI
  D. Prism Central
  A. aCLI
