NCP-MCI 6.5 Exam Questions with
Correct Answers
Why has an anomaly been triggered?
A. Controller reached 2500 IOPS.
B. Observed IOPS exceed normal values.
C. Normal Controller behavior has increased.
D. Observed values do not match predicted values. - Answer-D. Observed values do
not match predicted values.
Answer: D
Explanation:
Nutanix anomaly detection is a feature that monitors seasonal trends for time-series
data (e.g. CPU
usage, memory usage, latency, etc.) and establishes a "band" of expected values
based on historical
data12. Only values that hit outside the "band" will trigger an event / alert1.
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.
2.An administrator is commissioning a Nutanix Enterprise Cloud. Once the user VMs
have been
deployed and are running, the administrator finds that VMs on the same host are able to
communicate,
but are unable to communicate between hosts.
What must be changed to enable full inter-VM communications?
A. Change the spanning-tree port type on the switch.
B. Change the network the VMs are connected to
C. Update the switch to specifically allow VLAN 15
D. The VMs need to have static IP addresses. - Answer-C. Update the switch to
specifically allow VLAN 15
,3.When installing Nutanix Guest Tools (NGT) on an ESXi-hosted VM, which port should
be enabled on
the VM to allow communication with the NGT-Controller VM service?
A. 2000
B. 2074
C. 8080
D. 9943 - Answer-B. 2074
4.An administrator wants to ensure that data in a container is stored in the most space
efficient manner
as quickly as possible after being written,
Which space efficiency too meets this requirement?
A. Inline Compression
B. Thin Provisioning
C. Cache Deduplication
D. Erasure Coding - Answer-A. Inline Compression
Answer: A
Explanation:
inline compression is a technique that compresses all incoming write I/O operations
over 4 KB inline in
the persistent write buffer (oplog)23. This approach enables you to use oplog capacity
more efficiently
and helps drive sustained performance2. From AOS 5.18 onward, inline compression
(compression
delay=0) is enabled by default for all new containers24.

5.An administrator was reviewing various AOS logs when a it was noticed that the time
of the logs were
off by several hours.
Which initial step was missed during the post process cluster configuration?
A. Setting the cluster time zone via PC GUI
B. Setting the cluster time zone via CVM NCLI
C. Setting the cluster time zone via PE GUI
D. Setting the cluster time zone via CVM ACLI - Answer-B. Setting the cluster time zone
via CVM NCLI
6.An administrator wants to reduce the largest amount of alert emails received from
Prism Central.
Which two settings should the administrator customize to meet this requirement?
(Choose two)
A. Skip empty digest email
B. Every Single Alert
,C. Dally Digest
D. Email Recipients - Answer-C. Dally Digest
D. Email Recipients
Answer: C,D
Explanation:
According to the Nutanix Support & Insights website1, you can configure alert emails
through Prism Central by enabling or disabling customer email notification for each
alert. You can also modify or create
custom alert policies for different entities and clusters23.
7.A configuration is single domain, single forest, and does not use SSL.
Which port number should be used to configure LDAP?
A. 389
B. 3269
C. 636
D. 3268 - Answer-A. 389
8.An administrator is reviewing performance of a core banking system that routinely has
20,000
concurrent users. During, business hours, the CPU on the applications servers runs at
close to 100%.
The administrator needs to determine if there is a performance issue specific to the app
servers, the
database servers, or all servers on the cluster.
Which metrics should the administrator review in Prism Analysis Graphs?
A. Cluster IO, Network, Database and App Server CPU
B. Cluster CPU and Memory Only
C. Cluster IO, CPU, Memory and Database and App Server CPU
D. Cluster IO, CPU, Memory, Network, App Server CPU - Answer-C. Cluster IO, CPU,
Memory and Database and App Server CPU
9.A customer has a newly-deployed AHV cluster with nodes that have 2.x 10 GBE and
2.x interface. The
customer wants to use all available network interfaces to provide connectivity to the
VMs.
Which option should the administrator use to achieve this while remaining consistent
with Nutanix
recommendations?
A. Create separate VLANs that map 10GbE and 1GbE interfaces.
B. Createbond1 on virbr0 and add the 1GbE interfaces to it for VM use.
C. Create a second bond on br0 on each host and assign the 1 GbE interfaces to it.
D. Create a second bridge on each host and assign the 1GbE interfaces to it. - Answer-
D. Create a second bridge on each host and assign the 1GbE interfaces to it.
, 10.An administrator manages an AHV cluster that is dedicated to a dev/test
environment. The
administrator receiving complaints from users that they are unable to create new VMs
on the cluster.
After the reviewing the cluster, the administrator finds that the memory resources are
almost fully utilized,
with many VMs over-provisioned on memory.
What option is the most efficient resolution to enable additional VMs to be created?
The safer , easier way to help you pass any IT exams.
A. Enable Memory Overcommit on the over-provisioned VMs.
B. Enable Memory HA on the over-provisioned VMs.
C. Upgrade the nodes with additional memory DlMMs.
D. Disable HA Reservation on the cluster. - Answer-A. Enable Memory Overcommit on
the over-provisioned VMs
Answer: A
Explanation:
Enable Memory Overcommit on the over-provisioned VMs is the most efficient
resolution to enable
additional VMs to be created. Memory overcommit allows VMs to use more memory
than physically
available on a host by compressing and swapping memory pages to storage1. This can
improve memory
utilization and increase VM density on a cluster1. However, memory overcommit is not
supported when
HA is configured to use reserved hosts, so you may need to disable HA reservation on
the cluster before
enabling memory overcommit1.
11.What is the expected behavior of the VMs residing on that host when a controller VM
becomes
unavailable?
A. A Live Migration will be performed on the affected VMs.
B. The host will automatically redirect I/O and VMs will continue running.
C. The impacted host and VMs will automatically shut down.
D. VM High Availability will restart the impacted VMs on another host - Answer-B. The
host will automatically redirect I/O and VMs will continue running.
12.Which method can be used to migrate a VM configured for UEFI-boot from a Nutanix
Hyper-V cluster
to AHV?
A. Live Migration
B. Storage vMotion
C. Nutanix Move
D. Cloud Connect - Answer-C. Nutanix Move
