Question 3

The administrator recently had a node fail in an AHV Nutanix cluster. All of the VMs restarted on other nodes in the cluster, but they discovered that the VMs that
make up a SQL cluster were running on the failed host. The administrator has been asked to take measures to prevent a SQL outage in the future.
What affinity option will prevent the SQL VMs from running on the same hos?

Accepted Answer

Answer A. VM-VM anti-Affinity policy
A VM-VM anti-Affinity policy is a rule that ensures that two or more VMs don??t run on the same AHV host. It??s useful when an application provides HA and an
AHV host can??t be an application??s single point of failure1. In this case, the SQL cluster VMs should have a VM- VM anti-Affinity policy configured to prevent
them from running on the same host and causing an outage if that host fails. A VM-VM anti-Affinity policy can be created using the aCLI commands2. The other
options are not relevant for this scenario.

Question 4

The customer is seeing high memory utilization on a mission critical VM. Users report that the application is unavailable. The guest OS does not support hot add
components.
How should the administrator fix this issue?

Accepted Answer

The best way to fix this issue is to increase the amount of memory assigned to the VM from the Prism web console. This option allows the administrator to modify
the VM configuration without accessing the CVM or shutting down the VM. The Prism web console provides a simple and intuitive interface for managing Nutanix
clusters and VMs1. To change the memory allocation for a VM, the administrator can follow these steps2:
? Go to the VM dashboard
? Select the VM from the VMs list
? Choose Update
? Adjust the amount of memory assigned to the VM

Question 5

A system administrator needs to add more VMs to their Nutanix cluster.
Which two actions should the administrator perform to determine if the current cluster can accommodate the new VMs? (Choose two)

Accepted Answer

According to the web search results, the two actions that the administrator should perform to determine if the current cluster can accommodate the new VMs are:
? Utilize Optimize Resources for VM efficiency: Optimize Resources is a feature in
Prism Central that helps the administrator improve the efficiency and performance of their VMs by identifying and resolving issues such as overprovisioning,
inactivity, constraints, or bullying3. By using Optimize Resources, the administrator can reclaim unused resources and optimize the resource allocation for their
VMs3.
? Determine utilization with Cluster Runway: Cluster Runway is a feature in Prism Central that helps the administrator estimate how long their cluster can continue
to run normally based on the current consumption rate of CPU, memory, and storage resources4. By using Cluster Runway, the administrator can see how adding
more VMs will affect the resource utilization and capacity of their cluster4.

Question 6

A vDisk is read by multiple VMs. The cluster creates immutable copies of the vDisk. What are these vDisk copies called?

Accepted Answer

According to the Nutanix Support & Insights web search result3, shadow clones are vDisk copies that are created by the cluster when a vDisk is read by multiple
VMs. Shadow clones are immutable copies of a vDisk that are stored in different nodes in the cluster, and are used to improve read performance and reduce
network traffic. Shadow clones are automatically created and deleted by the cluster, based on the demand and availability of resources.

Question 7

An administrator would like to leverage the Reliable Event Logging Protocol (RELP) with their Remote Syslog Server. After completing the configuration, it is
observed that RELP logging is not working as expected.
What is the likely cause of this issue?

Accepted Answer

According to the Red Hat Customer Portal, to use RELP with Rsyslog, you need to install the rsyslog-relp package on both the server and the client. If the remote
server does not have rsyslog-relp installed, RELP logging will not work as expected.

Question 8

Which AOS process determine if an I/O from a user will be written to OpLog or to an Extent Store?

Accepted Answer

Stargate is the AOS process that handles all I/O operations for the cluster. It is responsible for determining whether an I/O from a user will be written to the OpLog
or to the Extent Store, based on the type and size of the I/O. Stargate also performs data tiering, compression, deduplication, and erasure coding1. Stargate runs
on every CVM and communicates with other Stargates to ensure data locality and redundancy2.

Question 9

Refer to Exhibit:

From SurePassExam
https://www.surepassexam.com/NCP-MCI-6.5-exam-dumps.html (178 New Questions)
Why has an anomaly been triggered?

Accepted Answer

Nutanix leverages a method for determining the bands called ??Generalized Extreme Studentized Deviate Test??. A simple way to think about this is similar to a
confidence interval where the values are between the lower and upper limits established by the algorithm.
Another web source3 shows an example of how anomaly detection works in Nutanix Prism Central. In the video, you can see that when the observed value of a
metric deviates significantly from the predicted value based on historical data, an anomaly event is triggered and displayed on a chart.
Therefore, by comparing the observed values with the predicted values based on historical data, Nutanix anomaly detection can identify abnormal behavior and
alert you accordingly.

Question 10

An administrator has been asked to enable block awareness and increase the fault tolerance to FT2 on a Nutanix AHV cluster with the following configuration:
Four blocks
One node per block
Will the administrator be able to accomplish these tasks?

Accepted Answer

Fault tolerance (FT) is the ability of a cluster to withstand node failures and maintain data availability. FT is determined by the replication factor (RF) of the data,
which is the number of copies of each data block stored on different nodes. FT = RF - 1, meaning that the cluster can tolerate as many node failures as one less
than the RF. Block awareness is a feature that enhances fault tolerance by ensuring that data copies are distributed across different blocks, which are groups of
nodes that share a power source and network switch. Block awareness requires a minimum of three blocks and a minimum of six nodes in the cluster.
In this scenario, the administrator has been asked to enable block awareness and increase the fault tolerance to FT2 on a Nutanix AHV cluster with the following
configuration: Four blocks, One node per block. The administrator will not be able to accomplish these tasks because:
? To enable block awareness, the cluster needs at least six nodes, but it only has four nodes.
? To increase the fault tolerance to FT2, the cluster needs at least five nodes per RF3 or seven nodes per RF4, but it only has four nodes.
Therefore, the administrator will need to add more nodes to the cluster before enabling block awareness and increasing the fault tolerance to FT2.
