Nutanix NCA-6.5 Online Questions & Answers

• Question 111:

  An administrator manages a memory-sensitive application that consists of multiple VMs. The administrator needs to understand if workloads, historically, have been evenly distributed across these VMs. What should the administrator do?

  A. Create an Alert Policy with VM as entity type and memory usage as a metric.
  B. Run cluster efficiency summary report selecting all the VMs that constitute the applications.
  C. Add Memory usage chart to Analysis dashboard for each required VM.
  D. Filter VMs list by using Memory Usage.
  D. Filter VMs list by using Memory Usage.

• Question 112:

  How can an administrator determine if the cluster can sustain a hardware failure?

  A. Review the cluster Health
  B. Review the Hardware Summary
  C. Review the Data Resiliency Status
  D. Review the Storage Summary
  C. Review the Data Resiliency Status

• Question 113:

  In an AHV five-node cluster, an SSD fails within a node that has two SSDs and four HDDs installed. What will happen to the cluster environment?

  A. Host goes down and VMs will be powered on elsewhere.
  B. Cluster goes in read-only mode.
  C. VMs will be live migrated to other hosts until metadata rebuild is finished.
  D. CVM on the impacted node reboots.
  D. CVM on the impacted node reboots.

  ---

  Explanation/Reference:

  When an SSD fails within a node, the CVM on that node will reboot to maintain the health of the cluster. The CVM is responsible for managing the storage and virtualization components of the cluster, and a reboot is necessary to ensure that the cluster continues to function properly. The VMs running on that host will not be affected and continue to run, but the CVM will be unavailable for a short period of time until the reboot is completed. The Cluster continues to operate in a healthy state and doesn't go in read-only mode or cause any host to go down.

• Question 114:

  An administrator has defined a security policy that needs to be applied to dozens of VMs. What is the most efficient way the administrator can perform this?

  A. Within the policy, select all the VMs it should be applied to.
  B. Apply a category to the VMs. and associate the category with the policy.
  C. Apply the same label to all the VMs, then bind the policy to the label.
  D. Use a script to apply the policy to the defined VMs.
  C. Apply the same label to all the VMs, then bind the policy to the label.

  ---

  Explanation/Reference:

  Labels allow administrators to group related objects, such as VMs, and then apply policies to those labels, rather than having to manually apply the policy to each individual VM. This is the most efficient way for an administrator to apply a security policy to dozens of VMs. Reference: https://portal.nutanix.com/page/documents/details?targetId=Platform-Administrator-Guide-v5_7:pag-sec-category-label-c.html

• Question 115:

  Which tool provides diagnostic system data for Nutanix to deliver proactive support? (Choose Correct answer and give explanation/References from Nutanix Certified Associate (NCA) v6.5 official study resources)

  A. NCC
  B. Cluster Heart
  C. Pulse
  D. Cluster health
  C. Pulse

  ---

  Explanation/Reference:

  Pulse is a built-in tool that periodically collects and sends diagnostic data to Nutanix support for proactive monitoring and troubleshooting. This data includes cluster configuration, performance metrics, and error logs, among other things.

  Nutanix support can use this data to identify and resolve issues before they become critical, and to provide recommendations for optimizing cluster performance. NCC (Nutanix Cluster Check) is another tool provided by Nutanix, but it is used

  for performing manual health checks and diagnostics on the cluster, rather than providing proactive support.

  Cluster Heart and Cluster Health are not tools provided by Nutanix, and are not relevant to this question.

• Question 116:

  What is Hyperconverged Infrastructure (HO)?

  A. Consist of separate servers, storage networks and storage arrays.
  B. Consist of a combination of separate servers, storage and networks.
  C. A combination of servers and storage into a distributed infrastructure platform.
  D. A combination of servers and storage into a non-distributed infrastructure platform.
  C. A combination of servers and storage into a distributed infrastructure platform.

• Question 117:

  An administrator receives an alert that a node has failed within a Nutanix AHV-based 10-node cluster. Before the failure, the cluster CPU and memory utilization was around 50%.

  What actions will the cluster automatically take?

  A. VMs will be unavailable until the affected host is fully functional.
  B. VMs will migrate to other nodes in the cluster with no user impact.
  C. The cluster will enter read-only mode and the VMs will be powered down to preserve data.
  D. All HA-protected VMs will be automatically restarted on other nodes in the cluster.
  D. All HA-protected VMs will be automatically restarted on other nodes in the cluster.

  ---

  Explanation/Reference:

  Nutanix supports high availability (HA) for VMs by automatically restarting them on other nodes in the cluster in case of a node failure. The cluster CPU and memory utilization will increase temporarily until the failed node is recovered, but

  there will be no user impact. References:

• Question 118:

  What resource should be used to ensure a successful upgrade of the hypervisors and AOS within a vSphere-based Nutanix cluster?

  A. Upgrade Paths
  B. Field Advisories
  C. Compatibility and Interoperability Matrix
  D. Hardware Replacement Documentation
  C. Compatibility and Interoperability Matrix

  ---

  Explanation/Reference:

  The Compatibility and Interoperability Matrix (CIM) is the resource that should be used to ensure a successful upgrade of the hypervisors and AOS within a vSphere-based Nutanix cluster. The CIM provides information about the compatibility

  and interoperability of the different components of the Nutanix cluster, including the hypervisors, AOS, and other related components.

• Question 119:

  When should Pulse be disabled?

  A. When the cluster is connected to the Internet with less than 1GbE.
  B. When the cluster is deployed in 3 dark-site.
  C. Before any cluster maintenance activities requiring node reboots.
  D. Only under the guidance of Nutanix Support.
  D. Only under the guidance of Nutanix Support.

  ---

  Explanation/Reference:

  Pulse should only be disabled under the guidance of Nutanix Support and not for any other reason. Pulse is a feature of the Nutanix cluster that enables the cluster to report back health and performance data to Nutanix for troubleshooting and performance optimization purposes. Disabling Pulse without the guidance of Nutanix Support is not recommended, as it could lead to potential issues with the cluster.

• Question 120:

  How should an administrator enable the recycle bin on a nutanix cluster?

  A. Select the Enable Recycle Bin checkbox on the storage Overview page
  B. select Retain Deleted VMs for 8h in the cluster Details Page of the cluster setting
  C. Select the enable recycle bin checkbox in the configure CVM page of the cluster setting
  D. Select Retain Deleted VMs for 24h in the cluster details page of the cluster setting
  D. Select Retain Deleted VMs for 24h in the cluster details page of the cluster setting
