Nutanix NCA-6.5 Online Questions & Answers

• Question 11:

  Which Nutanix storage efficiency feature is suitable for nearly every workload?

  A. Erasure Coding
  B. Deduplication
  C. Compression
  D. Thick Provisioning
  C. Compression

  ---

  Explanation/Reference:

  Compression is a Nutanix storage efficiency feature that is suitable for nearly every workload, as it reduces the amount of data stored on disk without impacting performance. Erasure Coding, Deduplication, and Thick Provisioning are other

  storage efficiency features, but they have different trade-offs and use cases. References:

  Which URL can be used to open Nutanix support cases?

  A. portal.nutanix.com
  B. www.nutanix.com
  C. console.nutanix.com
  D. partnerportal.nutanix.com
  A. portal.nutanix.com

• Question 13:

  Where can an administrator find information about the Cluster Runway?

  A. Prism Element Home Page
  B. Prism Element Analysis
  C. Prism Central Main Dashboard
  D. Prism Central Analysis
  C. Prism Central Main Dashboard

  ---

  Explanation/Reference:

  The Cluster Runway is located in the Prism Element Analysis dashboard. The Cluster Runway provides an overview of the cluster's performance, including CPU, Memory, and Disk usage, and can be used to identify any potential performance issues.

• Question 14:

  A company's security team has requested that all IT resources be hardened.

  What should an administrator do to increase the security of the Nutanix environment?

  A. Enable Cluster Lockdown
  B. Enable Prism Central KMS
  C. Enable Flow
  D. Enable STIG
  D. Enable STIG

  ---

  Explanation/Reference:

  To increase the security of a Nutanix environment in response to a request from a company's security team, an administrator can Enable STIG (Security Technical Implementation Guide)

• Question 15:

  A 10 GbE link has failed on Node A within the following cluster environment:

  Four-node AHV-based cluster All node have only two 10 GbE ports connected to the network Active-backup is configured What impact will user VMs experience from this issue?

  A. Performance will Decrease
  B. Will failover to another node
  C. Will have no impact
  D. Will shutdown
  C. Will have no impact

  ---

  Explanation/Reference:

  In Active-backup mode, one network interface is active while the other is in standby mode. If the active interface fails, the standby interface takes over, providing seamless failover without any disruption to user VMs. In this case, since the cluster has two 10 GbE ports on each node, and only one link has failed, the user VMs will continue to operate normally using the second link.

• Question 16:

  Which type of network supports automatically assigning IP addresses to VMs?

  A. Floating IP Network
  B. Management traffic network
  C. Virtual Network with IPAM
  D. Virtual Private Cloud Networks
  C. Virtual Network with IPAM

  ---

  Explanation/Reference:

  A virtual network with IPAM (IP Address Management) supports automatically assigning IP addresses to VMs. This eliminates the need for manual configuration of IP addresses for each VM, and makes it easy to manage and track IP address usage.

• Question 17:

  Which cluster configuration is LCM unable to perform firmware upgrades against?

  A. Five-node
  B. Three-node
  C. Two-node
  D. Single--node
  D. Single--node

  ---

  Explanation/Reference:

  LCM (Lifecycle Manager) is a tool provided by Nutanix to automate software and firmware upgrades for Nutanix clusters. However, LCM is unable to perform firmware upgrades against a (D) Single-node cluster configuration. This is because a single-node cluster does not have any redundancy, so there is no way to perform an upgrade without taking the entire cluster offline. In contrast, multi-node clusters can typically be upgraded in a rolling fashion, with one or more nodes being upgraded at a time while the rest of the cluster remains online. LCM is capable of performing firmware upgrades against two-node, three-node, and five-node cluster configurations, as long as they meet the other requirements for LCM support (such as being on a supported AOS release and having the appropriate network connectivity).

• Question 18:

  Refer to the exhibit.

  

  A team member has built a CentOS VM image for use as a template. An administrator deploys a new VM using the CentOS image as the 05 drive. No other drives are presented to the VM.

  Following the deployment, the administrator attempts to boot the VM, but is unsuccessful.

  What could be causing this issue?

  A. The VMS Boot Priority must reference disk first before CD-ROW
  B. The VM's Disk (scsi.O) setting must be set to make this disk bootable
  C. No Volume Groups have been created for the VM
  D. The CentOS VM image was built with UEF:
  D. The CentOS VM image was built with UEF:

• Question 19:

  An administrator needs to upgrade AOS in a vSphere-based NutaniSJve-node cluster with no automatic live migration. VMs have neither affinity nor anti-affinity rules configured.

  What will happen to VMs during the AOS upgrade?

  A. VMs will be rebooted on other hosts.
  B. VMs will continue to run on the same host.
  C. Upgrade fails because host can't go in maintenance mode.
  D. AOS automatically live migrate VMs to other hosts.
  B. VMs will continue to run on the same host.

  ---

  Explanation/Reference:

  When upgrading AOS in a vSphere-based Nutanix cluster with no automatic live migration, the VMs will continue to run on the same host, providing that the VMs have neither affinity nor anti-affinity rules configured. The upgrade process will put the host into maintenance mode, which will cause the VMs running on that host to be suspended temporarily. Once the AOS upgrade is completed, the host will be taken out of maintenance mode, and the VMs will be resumed, but running on the same host. The AOS upgrade process does not automatically live migrate VMs to other hosts, because the automatic live migration feature is not enabled in the cluster.

• Question 20:

  Which technology allows applications and data to move freely between runtime environments?

  A. Distributed Storage Fabric
  B. Disaster Recovery
  C. App Mobility Fabric
  D. Nutanix Move
  C. App Mobility Fabric

  ---

  Explanation/Reference:

  App Mobility Fabric is a technology from Nutanix that allows applications and data to move freely between runtime environments. It allows applications and data to be moved from one environment to another without any disruption or downtime. Reference: https://www.nutanix.com/products/app-mobility-fabric
