Question 1
What do Nutanix Field Advisories communicate to customers?
A. Lists of certified third-party hardware vendors
B. New product releases and pricing updates
C. Installation procedures for new cluster deployments
D. Known issues, workarounds, and product impacts
Answer: D
Explanation
Field Advisories are proactive safety notices. If Nutanix discovers a bug that could cause data loss or a system crash under
specific conditions, they issue a Field Advisory so that administrators can apply a patch or change a setting before their own
cluster is affected.

Question 2
What are 2 requirements to upgrade Nutanix Guest Tools (NGT) on a VM? (Choose two.)
A. DNS Entry for VM
B. Empty CD Drive
C. VM Powered Off
D. VM Powered On
Answer: BD
Explanation
Upgrading NGT is an "in-guest" process. It requires the VM to be Powered On so the operating system is active, and it
requires an Empty CD Drive so that the Nutanix cluster can temporarily attach the upgrade ISO to the VM to perform the
installation.

Question 3
Which bond type provides the best utilization of multiple physical NICs in Nutanix cluster for VM traffic
throughput?
A. Active-Backup
B. Balance-slb
C. Balance-tcp
D. No Uplink Bond
Answer: C
Explanation
To achieve the highest possible network performance, Balance-tcp (LACP) is the preferred choice. It allows the cluster to
distribute network traffic across all available physical adapters in the bond. This is particularly beneficial for environments with
high-bandwidth requirements, as it maximizes the available "pipe" for VM data by intelligently spreading the load across the

Question 4
An admin is troubleshooting a VM that consumes excessive resources and is potentiallly impacting other
VMs.
Which VM Efficiency type refers to this type of VM?
A. Over-provisioned
B. Constrained
C. Inactive
D. Bully
Answer: D
Explanation
In Prism Central, VM efficiency categories help admins optimize the environment. A Bully VM is identified specifically so that
the admin can investigate whether the VM needs to be moved to a different node, given more resources, or capped to
prevent it from "starving" neighboring workloads of the resources they need to function.

Question 5
An admin is troubleshooting resource availability within the cluster. As part of the troubleshooting, the admin
wants to build a list of powered off VMs on the Nutanix cluster.
In order for these VMs to be listed in the Prism Central VM Efficiency widget, how many days must the VMs
be powered off to be considered a Dead VM?
A. 5
B. 15
C. 30
D. 45
Answer: C
Explanation
The VM Efficiency widget is designed to help reclaim wasted resources. By waiting 30 days before flagging a VM as "Dead,"
Nutanix ensures that it doesn't accidentally alert on VMs that are simply off for a short holiday or a standard monthly
maintenance cycle. This helps admins focus on truly abandoned workloads that are taking up storage space.

Question 6
A Virtual machine is experiencing delays even though its own CPU usage appears low.
Which metric should be checked to identify scheduling issues?
A. CPU Ready
B. Memory usage
C. Disk capacity
D. Snapshot size
Answer: A
Explanation
In a virtualized environment, CPU Ready is the "waiting room" metric. A VM might only be trying to use 10% of its CPU, but if
there are too many other VMs on that host, it may have to wait in line for its turn on the physical hardware. Monitoring this
metric is essential for identifying "noisy neighbor" problems or host over-subscription.

Question 7
How many Controller VMs (CVM) will a five-node HCI cluster have?
A. 3
B. 4
C. 5
D. 6
Answer: C
Explanation
The Nutanix architecture follows a 1-to-1 ratio between physical nodes and Controller VMs. Each CVM is responsible for
managing the local disks on its host and coordinating with other CVMs across the network. This distributed design ensures
that storage scales linearly as you add more nodes.

Question 8
What is the purpose of NCC?
A. To diagnose cluster health and identify configuration issues
B. To migrate VMs between different hypervisor types
C. To configure network microsegmentation for workloads
D. To deploy new Nutanix clusters across multiple sites
Answer: A
Explanation
NCC (Nutanix Cluster Check) serves as the primary diagnostic tool for Nutanix administrators. It is designed to proactively
detect performance bottlenecks, hardware failures, or configuration drift. By running these checks, administrators can ensure
the cluster adheres to best practices and identify exactly where a problem exists before it leads to downtime.

Question 9
What node type can be part of a HCI cluster but will not run user virtual machines?
A. Compute-Only
B. HCI
C. Storage-Only
D. Worker
Answer: C
Explanation
A Storage-Only node is used when a cluster needs more disk space but doesn't need more CPU or RAM for virtual
machines.
By adding a storage-only node, the cluster gets more capacity and better storage performance, but the node remains
dedicated to managing data, keeping its resources free from user VM interference.

Question 10
Which technology helps maintain operational resilience related to hardware?
A. Cluster Fault Tolerance
B. Acropolis Dynamic Scheduler
C. High Availability
D. Capacity Reservations
Answer: A
Explanation
Cluster Fault Tolerance is the backbone of Nutanix reliability. It ensures that data is replicated across different physical nodes
(Redundancy Factor). If a piece of hardware fails, the cluster uses its fault tolerance settings to ensure the data is still
accessible from another node, maintaining business continuity.

Question 11
Which Nutanix component is used to present Nutanix storage as iSCSI block targets to external
(non-virtualized) servers?
A. Storage Pool
B. vDisk Template
C. Storage Container
D. Volume Group
Answer: D
Explanation
Nutanix Volume Groups allow the cluster to act like a traditional SAN for external servers (like a physical SQL cluster). By
creating a Volume Group, the administrator defines an iSCSI target that the external server can log into, allowing it to treat
Nutanix storage as if it were a local physical disk.

Question 12
A volume group is a collection of which components?
A. Virtual disks
B. Controller VMs
C. Storage pools
D. Storage containers
Answer: A
Explanation
Think of a Volume Group as a "bundle" of disks.
For example, a database server might need five separate disks for logs and data. By putting them in a Volume Group, you
can manage them together and present them to the VM as a set of block devices.

Question 13
An admin has identified and resolved a critical alert on the health dashboard.
What should the admin do to confirm the alert/issue has been resolved?
A. Run NCC Checks
B. Delete the email notification
C. Mark alert as Resolved
D. Refresh Prism Element Dashboard
Answer: A
Explanation
The only way to be 100% sure a problem is fixed is to Run NCC Checks. This forces Nutanix to actively re-test the
component. If the check returns "Pass," the admin knows the cluster is healthy again.
