Nutanix Nutanix Certifications NCA-6.5 Questions & Answers

• Question 61:

  User are complaining that web application hosted on a Nutanix cluster are running slow. After reviewing the performance metric, it is determined that the CPU Ready time is high in the cluster. What entity is impacted by CPU ready time?

  A. Oplog

  B. NIC

  C. vDisk

  D. VM

  Correct Answer: A

  The oplog is a critical component of the Nutanix distributed storage fabric and can be impacted by high CPU Ready time. When the CPU Ready time is high, there can be delays in writing data to the oplog, resulting in slower overall cluster performance. Additionally, high CPU Ready time can also lead to increased write amplification, further reducing I/O performance.

• Question 62:

  An Administrator has created a Volume Group for a specific VM on an AHV Cluster. What is the next step required to user vDisk in the VM?

  A. Attach the Volume Group to the VM

  B. Configure CHAP Authentication

  C. Reboot the VMD. Bring the disk Online

  Correct Answer: A

• Question 63:

  An administrator needs to create a new chart to analyze GPU usage. Which entity should be added to the chart?

  A. Cluster

  B. Virtual Machine

  C. GPU

  D. Host

  Correct Answer: B

• Question 64:

  What is the minimum number of nodes needed to configure a Replication Factor of 2 (RF2)?

  A. 3

  B. 1

  C. 4

  D. 2

  Correct Answer: B

• Question 65:

  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

  Correct Answer: C

  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 66:

  An administrator needs to migrate a running VM's vDisks to another container without downtime.

  Which tool should the administrator use to satisfy this task?

  A. aCLI

  B. Prism Element

  C. nCLI

  D. Prism Central

  Correct Answer: A

• Question 67:

  A Cluster is Experiencing an occasional issue that does not impact production services.

  Which support case priority level should be assigned?

  A. P1 ?Emergency

  B. P2 ?Critical

  C. P3 ?Normal

  D. P4 ?Low

  Correct Answer: C

  According to Nutanix Support Best Practices, P3 cases are designated for issues that have a moderate business impact or affect non-production systems. P3 cases are intended for issues that are important but not critical, and the issue can be deferred while continuing with normal business operations. Examples of P3 cases include software defects, minor configuration issues, or minor hardware problems.

• Question 68:

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

  A. Five-node

  B. Three-node

  C. Two-node

  D. Single--node

  Correct Answer: D

  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 69:

  In Prism Element, to which object are policies such as replication factor and storage efficiency settings applied?

  A. Container

  B. Virtual Machine

  C. Storage Pool

  D. vBlock

  Correct Answer: A

  In Prism Element, policies such as replication factor and storage efficiency settings are applied to Containers. A container is a logical grouping of one or more storage pools and defines the storage resources available to virtual machines. By applying policies to a container, you can set the replication factor, storage efficiency settings, and other storage-related settings for all of the virtual machines that are associated with that container. This is a fundamental concept in Nutanix Platform.

• Question 70:

  When creating a virtual switch on an AHV cluster, what is the recommended configuration method?

  A. Manual

  B. Automatic

  C. Standard

  D. Quick

  Correct Answer: C
