Nutanix NCA-6.5 Online Practice Questions and Exam Preparation

Nutanix NCA-6.5 Online Questions & Answers

• Question 31:

  An administrator is unable to discover a Nutanix-hosted iSCSI block device allocated to a bare-metal host. What is causing this issue?

  A. Jumbo frames has not been configured on the switch
  B. External client access has not been enabled for the host
  C. Network segmentation has not been enabled
  D. External host IP address is not in the Filesystem Whitelist
  D. External host IP address is not in the Filesystem Whitelist

  ---

  Explanation/Reference:

  Nutanix Volumes uses a Filesystem Whitelist to control which external hosts can access the iSCSI block devices allocated to them. If the external host IP address is not in the Filesystem Whitelist, it will not be able to discover or connect to the

  Nutanix-hosted iSCSI block device. Jumbo frames, external client access, and network segmentation are not required for Nutanix Volumes to work. References:

• Question 32:

  Which Nutanix concept is responsible for accommodating and remediating node failure scenarios?

  A. Life cycle management
  B. Auto resolve mode
  C. Data locality
  D. Self healing
  C. Data locality

• Question 33:

  An administrator has been tasked with delivering a report on all nutanix Field Advisors (FAs) Affecting each of the clusters.

  What is the most efficient way to collect this data?

  A. Request an environmental audit from the Nutanix Support
  B. Use Prism to run NCC and Check for information on FAs
  C. Review the discoveries information on the support Portal
  D. Review Field Advisories published on the Support Portal
  B. Use Prism to run NCC and Check for information on FAs

• Question 34:

  Which Nutanix data efficiency mechanism replaces a traditional Replication Factor for suitable data?

  A. Compression
  B. Deduplication
  C. Erasure Coding
  D. Intelligent Cloning
  C. Erasure Coding

  ---

  Explanation/Reference:

  Erasure coding is a data efficiency mechanism in Nutanix that replaces the traditional replication factor for suitable data. Erasure coding uses a technique known as "forward error correction" to spread data across multiple drives in a cluster, such that if some drives fail, the data can still be reconstructed. This allows for a much higher storage density and a more efficient use of disk space as compared to traditional replication, where multiple copies of the same data are stored across multiple drives. Deduplication and Compression are also data efficiency mechanisms in Nutanix which help to reduce the storage overhead by eliminating the redundant data. Intelligent Cloning is a Nutanix feature which helps to create multiple instant, space-efficient clones of a VM.

• Question 35:

  Which Prism Central feature can map images to target clusters using categories?

  A. Image Replication Policies
  B. Image Placement Policies
  C. Protection Domain Policies
  D. Storage Policies
  B. Image Placement Policies

  ---

  Explanation/Reference:

  In Prism Central, Image Placement Policies can be used to map images to target clusters using categories. An Image Placement Policy is a set of rules that determine where an image should be placed on the Nutanix cluster. These rules are based on categories, such as the image's OS type, the target cluster's hardware type, and other factors. By creating image placement policies, you can ensure that images are placed on the appropriate clusters, and that they are compatible with the hardware and software requirements of those clusters. For example, you could create a placement policy that specifies that all Windows images should be placed on a specific cluster, and that all Linux images should be placed on another cluster. You can also set image replication policies on image placement policies, to ensure that images are replicated to multiple clusters for disaster recovery purposes.

• Question 36:

  From Prism Central, how can an administrator access a cluster?

  A. Use the VM Summary view.
  B. Use the cluster quick access from the main dashboard widget.
  C. Use the cluster quick access from the Settings page.
  D. Use the Cluster Summary view.
  B. Use the cluster quick access from the main dashboard widget.

  ---

  Explanation/Reference:

  From Prism Central's main dashboard page, an administrator can access any cluster by clicking the cluster quick access link. This will open the cluster summary page, which contains detailed information about the cluster, including the nodes, virtual machines, and applications running on the cluster.

• Question 37:

  Which AHV feature proactively monitors a Nutanix cluster for compute and storage I/O contention or hot-spots over a period of time?

  A. Genesis
  B. ADS
  C. Prism
  D. Cluster Maintenance Utility
  B. ADS

  ---

  Explanation/Reference:

  ADS is a feature of Nutanix AHV (Acropolis Hypervisor) that proactively monitors a Nutanix cluster for compute and storage I/O contention or hotspots over a period of time [1]. It provides dynamic and intelligent scheduling of workloads on the cluster for optimal performance and utilization.

• Question 38:

  An application owner had reported that an AHV-based critical application VM is performing very slowly. After initial diagnostics, it has been observed that the CPU utilization is significantly higher than normal.

  What two actions should the administrator take on this VM without shutting it down? (Choose two.)

  A. Increase number of vCPU in Prism Element
  B. Configure additional cores in acli
  C. Ensure CPU hot-add is supported by the Guest
  D. Use PrismElement to increase the number of cores
  A. Increase number of vCPU in Prism Element
  C. Ensure CPU hot-add is supported by the Guest

• Question 39:

  Refer to the exhibit.

  

  An administrator notices that the Data Resiliency Statue of some components has been reduced to 0. making it impossible to support a

  node failure in the cluster.

  What type of failure is most likely the cause of this issue?

  A. Block
  B. Disk
  C. CVM
  D. Nods
  C. CVM

• Question 40:

  Which directory should the LCM Framework Bundle be extracted to on a dark site web server in order to update the LCM Framework?

  A. release
  B. upgrade
  C. software
  D. install
  A. release

  ---

  Explanation/Reference:

  When updating the LCM Framework on a dark site web server, the LCM Framework Bundle should be extracted to the "release" directory. This directory is specifically designated for holding the updated LCM Framework files, and the update process will look for the files in this location. Extracting the bundle to a different directory, such as "upgrade", "software" or "install" would not be sufficient as the LCM Framework update process may not be able to find the files.
