Free Nutanix NCA-5.15 Question and Answers

Question 1

Which concept of Nutanix is responsible for accommodating and remediating different types of node failures?

Accepted Answer

Data locality

Answer

Data locality refers to the concept of storing data in close proximity to the compute resources that require it. It aims to reduce data access latency by placing data on the same physical node or in the same locality group as the applications or virtual machines that need to access it frequently. Data locality can enhance performance by minimizing data transfer across the network.

Question 2

An administrator needs to increase the size of a Nutanix cluster that tags network traffic at both the CVM and AHV levels. The administrator, on the other hand, cannot recall the VLAN ID that was configured. Which command should the administrator execute in order to retrieve the appropriate VLAN ID from the CVM?

Accepted Answer

ovs-vscl

Answer

To retrieve the appropriate VLAN ID from the CVM (Controller Virtual Machine) using the "ovs-vsctl" command, the administrator can execute the following command:
sudo ovs-vsctl show
This command displays the current configuration of the Open vSwitch (OVS) on the CVM, including the configured VLAN IDs.

Question 3

An administrator is worried about the performance of a virtual machine (VM) that is hosted on a hybrid cluster and has 8 gigabytes of RAM and 4 virtual CPUs. An examination of the VM reveals that the CPU is being utilized in a manner that is equal to 50%. Memory is being used up to 30% of its capacity. and the disk latency is 18 ms. What kinds of actions can the administrator take to boost performance?

Accepted Answer

Enable Flash Mode

Answer

Enabling Flash Mode, if available in the hybrid cluster, can improve VM performance by utilizing flash-based caching for frequently accessed data. Flash Mode leverages the faster storage capabilities of flash-based devices to enhance overall storage performance and reduce latency.

Question 4

An administrator makes an effort to reinstall QuestOS on a virtual machine (VM), but he is unable to change the legacy BIOS hoot priority. What do you think is causing this problem, taking into consideration the exhibit?

Accepted Answer

The VM is currently on

Answer

The phrase "The VM is currently on" typically implies that the virtual machine (VM) in question is powered on or running at the present moment. It suggests that the VM is actively running its operating system and executing applications or services.
In virtualization terminology, a VM can be in one of two states: powered on (running) or powered off (shut down). When a VM is "on," it means that it is in an operational state, utilizing the allocated computing resources and actively serving its intended purpose.

Question 5

A customer requires the capability to block all network traffic between their VDI virtual machines (VMs) and their application virtual machines (VMs) which are running on their Nutanix AHV clusters. Which product offered by Nutanix would be suitable for fulfilling these requirements?

Accepted Answer

Flow

Answer

Nutanix Flow is a software-defined networking (SDN) solution provided by Nutanix. It enables network microsegmentation, security policy enforcement, and application-centric visibility within Nutanix AHV environments. Flow allows administrators to create fine-grained network security policies and control traffic flow between VMs based on various factors such as VM attributes, applications, and user identity.
By utilizing Nutanix Flow, customers can establish security policies to isolate and restrict network traffic between VDI VMs and application VMs, ensuring that communication is limited to authorized connections only. This helps enhance security, protect sensitive data, and maintain a controlled network environment within the Nutanix AHV clusters.
