Nutanix NCS-Core Test Dumps

D.   FVM: 10.170.25.2/24, Laptop: 10.170.25.12/24

Answer DescriptionExplanation: Based on the subnet assignments from the exhibit provided, the Hypervisor Management IP addresses fall within the 10.170.0.5, 10.170.0.6, 10.170.0.7 range with a subnet mask of 255.255.240.0, indicating a /20 subnet. However, the Foundation VM (FVM) and the Consultant Laptop should ideally be on the same subnet as the Controller Virtual Machine (CVM) to facilitate easy access and management. The CVM IP addresses indicated are 10.170.0.4, 10.170.0.9, and 10.170.0.10 with subnet 255.255.240.0 (/20). Thus, the appropriate choice for the FVM and Laptop that matches the subnet without overlapping with existing IPs and allows network configuration without conflicts would be in the same /24 range as suggested in option D, i.e., FVM: 10.170.25.2/24, Laptop: 10.170.25.12/24.

A.   Check the factory_config.json for all 3 nodes

Answer DescriptionExplanation: When nodes are added to a Nutanix cluster and there is a discrepancy in the position or configuration as shown in the hardware diagram tab, it's essential to check the factory_config.json file on all newly added nodes. This file contains important configuration details that define how each node is identified and operates within the cluster. Incorrect or inconsistent settings in the factory_config.json can lead to display and configuration errors in the Prism interface. Correcting any discrepancies in this file will help resolve issues with node identification and display in the diagram tab.

C.   Enable Cluster Lockdown and provide an RSA key.

Answer DescriptionExplanation:
The most straightforward approach for increasing security by disabling password authentication and moving to key-based SSH on a Nutanix cluster involves:
C. Enable Cluster Lockdown and provide an RSA key: Cluster Lockdown mode restricts management access to the cluster, ensuring that only key-based SSH authentication is used to access the CVM and AHV hosts, enhancing security by eliminating the use of passwords.

B.   Foundation Portable


D.   Foundation Applet

Answer DescriptionExplanation: When a consultant is unable to install virtualization software on a laptop, the most suitable versions of Foundation to resolve this issue would be Foundation Portable (Option B) and Foundation Applet (Option D). Both these versions are designed to be used in environments where installing additional virtualization software might not be feasible. Foundation Portable can be run from a USB drive, and the Foundation Applet is a Javabased tool that can run directly on a host machine without the need for a full virtual machine environment.

D.   Post-Process Compression

Answer DescriptionExplanation:
Erasure coding is a method of data protection in which data is broken into fragments, expanded and encoded with redundant data pieces, and stored across a set of different locations or storage media. The goal of erasure coding is to enable data that becomes corrupted at some point in the disk storage process to be reconstructed by using information about the data that’s stored elsewhere in the array1.
In the context of Nutanix, erasure coding increases the usable capacity on a cluster. Instead of replicating data, erasure coding uses parity information to rebuild data in the event of a disk failure1. The capacity savings of erasure coding is in addition to deduplication and compression savings1.
Given the characteristics of the VM in the question (large/sequential writes, data kept for years, data accessed only at the end of the year), Post-Process Compression would be the most suitable feature to utilize to save space. This is because Post-Process Compression, as the name suggests, compresses data after it has been written to the storage, which is suitable for data that is not accessed frequently2.

D.   Integrate AD authentication on all Prism Element Clusters.

Answer DescriptionExplanation: When managing multiple Nutanix AHV clusters across various locations with a centralized management through Prism Central, it is essential to secure each cluster individually. Integrating Microsoft Active Directory authentication directly on all Prism Element clusters allows each site to independently authenticate users while still being centrally managed. This method aligns with security policies that require network devices to authenticate via AD groups, ensuring that local administrative actions at each site are also secured under the same policy.

B.   nutanix@cvm~$ ncli cluster get-domain-fault-tolerance-status type=node

Answer DescriptionExplanation: To verify that a Nutanix cluster can tolerate a single-node failure, the consultant should use the command nutanix@cvm~$ ncli cluster get-domain-fault-tolerance-status type=node. This command is executed from the Controller Virtual Machine (CVM) and checks the cluster's fault tolerance status specifically for node failures, providing insights into how the cluster's data resiliency and redundancy configurations are holding up against potential single-node failures.

A.   16

Answer DescriptionExplanation: In a Nutanix Files deployment within a 20-node AHV cluster, the consultant can deploy a maximum of 16 FSVMs (File Server Virtual Machines). This limitation is based on Nutanix's best practices and design considerations for scalability and performance. The number of FSVMs that can be effectively managed and maintained without degrading the performance of the file-serving operations or the underlying storage infrastructure dictates this maximum.
