Question: 402
A Nutanix administrator wants to implement a data protection strategy for a set
of mission-critical VMs. Which Nutanix feature should be used to achieve this
requirement?
A. Nutanix Calm
B. Nutanix Karbon
C. Nutanix Mine
D. Nutanix Backup
Answer: D
Explanation: Nutanix Backup is the Nutanix feature designed to provide data
protection and backup capabilities for VMs, including mission-critical VMs. It
allows administrators to implement a comprehensive data protection strategy
for their Nutanix environment.
Question: 403
A Nutanix cluster is configured with an AHV hypervisor. The customer wants
to use Nutanix's built-in backup and restore functionality to protect their VMs.
Which two steps should the consultant take to implement this? (Choose two)
A. Enable the Nutanix Veeam backup integration
B. Enable the Nutanix Backup & Replication feature
C. Create a backup policy and schedule for the VMs
D. Install the Nutanix Backup Appliance on the cluster
Answer: B, C
Explanation: To use Nutanix's built-in backup and restore functionality, the
consultant should enable the Nutanix Backup & Replication feature and create
a backup policy and schedule for the VMs. The Nutanix Backup Appliance is
not required for this functionality.
Question: 404
A customer has a Nutanix cluster with multiple virtual machine (VM) tiers,
each with different performance requirements. The consultant needs to ensure
that the high-performance VMs receive the necessary resources while the
lower-performance VMs are not affected. Which Nutanix feature should the
consultant use to achieve this?
A. Compression
B. Storage Tiering
C. Quality of Service (QoS)
D. Acropolis Volume Groups
Answer: C
Explanation: The correct answer is C. Quality of Service (QoS) is the Nutanix
feature that the consultant should use to ensure that the high-performance VMs
receive the necessary resources while the lower-performance VMs are not
affected. QoS allows the administrator to set policies that prioritize specific
workloads or applications, ensuring they receive the required resources and
maintain their performance.
Question: 405
An administrator wants to upgrade the Nutanix Cluster to a newer version of
AOS. Which of the following is the recommended approach?
A. Perform a rolling cluster upgrade
B. Perform a parallel cluster upgrade
C. Perform a full cluster reinstall
D. Perform a rolling hypervisor upgrade
Answer: A
Explanation: The correct answer is A. Performing a rolling cluster upgrade is
the recommended approach for upgrading a Nutanix Cluster to a newer version
of AOS. A rolling upgrade allows the cluster to be upgraded one node at a
time, minimizing downtime and maintaining the availability of the cluster.
Question: 406
A Nutanix cluster is experiencing high disk latency. Which two Nutanix
features can be used to optimize disk performance? (Choose two.)
A. Compression
B. Deduplication
C. Erasure Coding
D. Tiering
Answer: B, D
Explanation: Deduplication and Tiering are Nutanix features that can be used to
optimize disk performance by reducing the amount of data stored and moving
frequently accessed data to faster storage tiers. Compression and Erasure
Coding are not directly related to optimizing disk performance.
Question: 407
An administrator is planning to use Nutanix Volumes to host a set of VMs that
will be moved between different clusters. Which Nutanix Volumes feature
should they consider to ensure data mobility?
A. Snapshots
B. Replication
C. Compression
D. Deduplication
Answer: B
Explanation: The replication feature in Nutanix Volumes would be the most
appropriate choice for ensuring data mobility when moving VMs between
different clusters. Replication allows the administrator to synchronize the data
between clusters, enabling seamless migration of the VMs.
Question: 408
Which Nutanix feature provides backup and recovery capabilities for virtual
machines?
A. Nutanix Mine
B. Nutanix Snapshots
C. Nutanix Replication
D. Nutanix Data Protect
Answer: D
Explanation: Nutanix Data Protect is the feature that provides backup and
recovery capabilities for virtual machines running on the Nutanix platform. It
allows administrators to create and manage backup schedules, perform filelevel
and VM-level restores, and implement long-term data retention policies.
Question: 409
A Nutanix cluster is experiencing a high rate of node failures, and the
administrator suspects that the issue is related to a hardware problem. What
should the administrator do to identify the root cause of the issue?
A. Check the cluster health dashboard
B. Analyze the node failure logs
C. Reboot the affected nodes
D. Replace the affected hardware components
Answer: B
Explanation: To identify the root cause of the high node failure rate, the
administrator should analyze the node failure logs, which can provide valuable
information about the underlying hardware issues causing the failures.
Question: 410
A customer wants to implement a backup and recovery strategy for their
Nutanix cluster. Which two Nutanix features should the consultant
recommend? (Choose two)
A. Nutanix Snapshots
B. Nutanix Replication
C. Nutanix Karbon
D. Nutanix Files
Answer: A, B
Explanation: Nutanix Snapshots and Nutanix Replication are the two primary
Nutanix features that can be used to implement a comprehensive backup and
recovery strategy. Nutanix Karbon and Nutanix Files are not directly related to
the backup and recovery use case.
Question: 411
What is the purpose of the Nutanix Acropolis Hypervisor (AHV) in Nutanix
AOS 6.5?
A. To provide storage management
B. To provide network management
C. To provide virtualization management
D. To provide backup and restore functionality
Answer: C
Explanation: The Nutanix Acropolis Hypervisor (AHV) in Nutanix AOS 6.5 is
the virtualization management component that provides virtualization
management capabilities.
Question: 412
A customer wants to implement a disaster recovery (DR) solution for their
Nutanix cluster. They have a secondary site with an identical Nutanix cluster.
Which two steps should the consultant take to configure the DR solution?
(Choose two)
A. Enable replication between the primary and secondary clusters
B. Create a backup policy for the VMs on the primary cluster
C. Configure network and storage connectivity between the primary and
secondary sites
D. Install the Nutanix Cluster Conversion tool on both the primary and
secondary clusters
Answer: A, C
Explanation: To configure a disaster recovery solution for a Nutanix cluster, the
consultant should enable replication between the primary and secondary
clusters and ensure that there is proper network and storage connectivity
between the two sites. The Nutanix Cluster Conversion tool is not required for
this DR configuration.
Question: 413
A Nutanix cluster is experiencing high CPU utilization, and the administrator
wants to investigate the root cause. During the investigation, the administrator
notices that the cluster's hypervisor is set to KVM. What should the
administrator consider to optimize the CPU utilization in this scenario?
A. Migrate the hypervisor to ESXi.
B. Migrate the hypervisor to Hyper-V.
C. Upgrade the hypervisor to the latest version of KVM.
D. Ensure the cluster's hardware is compatible with the KVM hypervisor.
Answer: A
Explanation: In the Nutanix ecosystem, the recommended hypervisor is ESXi,
as it is generally more optimized for CPU utilization compared to KVM.
Migrating the hypervisor from KVM to ESXi can help optimize the CPU
utilization and improve the overall performance of the cluster.
Question: 414
A Nutanix cluster has a replication factor of 2. If a single node fails, how many
copies of each data block will be available?
A. 1
B. 2
C. 3
D. 4
Answer: C
Explanation: With a replication factor of 2, each data block is replicated twice
across the cluster. If a single node fails, the remaining two copies of each data
block will still be available, resulting in 3 total copies of each block.
Question: 415
A Nutanix cluster is experiencing high network latency, and the administrator
observes that the cluster's network utilization is consistently above 80%. What
should the administrator do to resolve this issue?
A. Increase the number of network interfaces
B. Disable network Quality of Service (QoS)
C. Implement network traffic shaping
D. Migrate the VMs to a different Nutanix cluster
Answer: A
Explanation: When a Nutanix cluster experiences high network latency due to
high network utilization, the administrator should increase the number of
network interfaces. Adding more network interfaces will provide more network
capacity and bandwidth to handle the increased network traffic, reducing the
overall network latency.
