Based on the exhibit, what is required to meet the customer's budgetary timeframe?
A. Add resources to the cluster.
B. Postpone the start of new workloads.
C. Delete workloads running on the cluster.
D. Change the target to 9 months.
Answer: A
Explanation:
The exhibit shows that the overall runway is only 66 days, meaning that the current
cluster does not have enough capacity to sustain workloads for 6 months, let alone 9
months.
The best solution is to add resources to the cluster (Option A), such as CPU, memory,
or storage, to extend the runway.
Postponing new workloads (Option B) may help in the short term but does not align
with the business need to continue adding workloads.
Deleting workloads (Option C) is not a viable option because the customer wants to
add more, not remove them.
Changing the target to 9 months (Option D) does not change the actual resource
constraints; it only
alters the target timeframe.

However, the Compatible Remote Sites screen does not list all required storage
containers.
Which two reasons could be a cause for this issue? (Choose two.)
A. Source and destination hardware are from different vendors.
B. The remote site storage container has compression enabled.
C. The destination storage container is not empty.
D. Both storage containers must have the same name.
Answer: C, D
Explanation:
For Metro Availability to work properly, the storage containers at both the primary and
secondary sites must meet certain requirements:
The storage containers must have the same name (Option D). This ensures that
replication and failover work seamlessly. If the names do not match, the storage
containers will not be listed as compatible.
The destination storage container must be empty (Option C). Metro Availability
requires a clean storage container at the secondary site to receive data. If the
container already contains data, it cannot be used.
Option A is incorrect: Different vendor hardware does not affect Metro Availability
compatibility.
Option B is incorrect: Compression does not affect Metro Availability compatibility.
However, it is recommended to keep compression settings aligned between sites.

After reviewing the VM’s CPU Ready Time data shown in the exhibit, which step
should the administrator take to diagnose the issue further?
A. Check the number of vCPUs assigned to each CVM.
B. Review host CPU utilization.
C. Assess cluster SSD capacity.
D. Enable VM memory oversubscription.
Answer: B
Explanation:
Understanding the Issue
The administrator is investigating VM performance complaints and is analyzing CPU
Ready Time data.
CPU Ready Time is a crucial metric in Nutanix and virtualization environments (AHV,
ESXi, or Hyper-V).
It measures the amount of time a VM is waiting for CPU scheduling due to resource
contention.
High CPU Ready Time indicates that VMs are ready to run but are waiting because
the host lacks
available CPU resources.
Analysis of the Exhibit
The graph shows CPU Ready Time spikes for multiple VMs.
Some VMs have CPU Ready Time exceeding 18% to 21.5%, which is very high.
A healthy CPU Ready Time should be below 5%.
Values above 10% indicate CPU contention, and anything above 20% is critical and
requires

immediate troubleshooting.
Evaluating the Answer Choices
? (A) Check the number of vCPUs assigned to each CVM. (Incorrect)
CVMs (Controller VMs) have fixed CPU allocation, and modifying their vCPU count is
not recommended unless advised by Nutanix Support.
The issue is related to VM CPU contention, not CVM configuration.
? (B) Review host CPU utilization. (Correct Answer)
High CPU Ready Time suggests CPU overcommitment or host saturation.
The administrator should check host CPU usage in Prism Central to determine if the
cluster is overloaded.
If host CPU usage is consistently above 85C90%, VMs are competing for CPU
resources, leading to high CPU Ready Time.
? (C) Assess cluster SSD capacity. (Incorrect)
SSD capacity impacts storage performance (latency, read/write speeds) but does not
affect CPU Ready Time.
High CPU Ready Time is a CPU scheduling issue, not a storage bottleneck.
? (D) Enable VM memory oversubscription. (Incorrect) Memory oversubscription does
not impact CPU scheduling.
Enabling memory oversubscription affects RAM allocation, but CPU Ready Time is
strictly related to CPU contention.
Next Steps to Diagnose & Resolve the Issue Review Host CPU Utilization:
Navigate to Prism Central ? Analysis ? CPU Usage per Host. Identify hosts
experiencing high CPU load.
Check VM vCPU Allocation:
Ensure that VMs do not have excessive vCPUs assigned, which can lead to
scheduling inefficiencies. Overprovisioning vCPUs can cause unnecessary
contention.
Balance Workload Across Hosts:
Use Nutanix AHV DRS (Dynamic Scheduling) or VMware DRS to redistribute VMs
across hosts. Check if certain hosts are overloaded while others have spare CPU
capacity.
Consider Scaling Out the Cluster:
If CPU usage is consistently high, adding more nodes may be required to reduce
CPU contention. Multicloud Infrastructure Reference & Best Practices
CPU Ready Time Best Practices: Keep CPU Ready Time below 5%.
Avoid overcommitting vCPUs on heavily loaded hosts.
Monitor Prism Central Runway Metrics to predict future CPU resource needs. Nutanix
AHV CPU Scheduling Optimization:
Ensure proper VM sizing (avoid excessive vCPU allocation). Balance workloads using
Nutanix AHV DRS.

In a scale-out Prism Central deployment, what additional functionality does
configuring an FQDN instead of a Virtual IP provide?
A. Load balancing
B. Resiliency
C. Segmentation
D. SSL Certificate
Answer: A
Explanation:
When using FQDN instead of a Virtual IP in a scale-out Prism Central deployment,
Nutanix enables load balancing across multiple Prism Central instances.
Option A (Load balancing) is correct because it ensures that requests are distributed
among multiple Prism Central nodes, improving performance and redundancy.
Option B (Resiliency) is incorrect because resiliency is achieved through HA and
replication, not through FQDN configuration.
Option C (Segmentation) is incorrect because network segmentation is handled at the
VLAN or security policy level.
Option D (SSL Certificate) is incorrect because SSL certificates can be applied
regardless of whether
FQDN or Virtual IP is used.

After adding new workloads, why is Overall Runway below 365 days and the scenario
still shows the cluster is in good shape?
A. Because Storage Runway is still good.
B. Because new workloads are sustainable.
C. Because there are recommended resources.
D. Because the Target is 1 month.
Answer: B
Explanation:
In Nutanix Capacity Planning, Overall Runway represents how long the cluster can
support current and new workloads before resources are exhausted.
Even if the runway is below 365 days, the system considers the cluster to be in good
shape if new workloads are sustainable (Option B).
Option A is incorrect: Storage runway alone is not the only factor; CPU and memory
are equally important.
Option C is incorrect: The presence of recommended resources does not mean the
cluster is in good
shape.
Option D is incorrect: The target of 1 month affects projections but does not explain
why the cluster
is in good shape.

6.An administrator needs to set up a protection policy in preparation for a Disaster
Recovery (DR) test.
What is the first step required to satisfy this task?
A. Install NGT (Nutanix Guest Tools) on VMs where applications are supported.
B. Create an Availability Zone between Production and DR.
C. Convert the source cluster to AHV.
D. Create a point-in-time snapshot of source VMs.
Answer: B
Explanation:
For Nutanix Disaster Recovery (DR) protection policies, the first step is to establish a
connection between the Production cluster and the DR site, which is done by creating
an Availability Zone (AZ) (Option B).
Availability Zones (AZs) define remote sites for replication and are a requirement for
configuring protection domains and disaster recovery plans.
Option A (Installing NGT) is not necessary for setting up replication but is useful for
application-consistent snapshots.
Option C (Converting the source cluster to AHV) is not required, as Nutanix supports
cross-hypervisor DR between ESXi and AHV.
Option D (Creating a point-in-time snapshot) is a later step after setting up the
Availability Zone and
Protection Policy.

7.An administrator wants to ensure that VMs can be migrated and restarted on
another node in the event of a single-host failure.
What action should be taken in Prism Element to meet this requirement?

B. Enable HA Reservation.
C. Configure a Protection Domain.
D. Configure an RF1 storage container.
Answer: B

To ensure VM high availability (HA) in the event of a node failure, the administrator
must enable HA Reservation (Option B) in Prism Element.
High Availability (HA) in Nutanix ensures that VMs restart on another available node if
the host they are running on fails.
Option A (Redundancy Factor 3) affects storage redundancy, not VM failover.
Option C (Protection Domains) is related to disaster recovery (DR), not local HA
failover.
Option D (RF1 Storage Container) would reduce fault tolerance and is not
recommended for
production environments.

8.An administrator started an LCM upgrade of the AHV hosts but realized that the
upgrade would exceed the planned maintenance window.
Which feature should be leveraged to prevent additional updates from occurring?
A. Cancel the LCM tasks via the Ergon command line (ecli).
B. Run the lcm_task_cleanup.py script.
C. Restart Genesis on the cluster to restart the LCM service.
D. Use the Stop Update feature in LCM.
Answer: D
Explanation:
When performing a Life Cycle Manager (LCM) upgrade, the recommended way to
stop the process is to use the “Stop Update” feature in LCM (Option D).
Option A (Cancel via Ergon ecli) is not a recommended approach since manually
interfering with running tasks can cause inconsistencies.
Option B (lcm_task_cleanup.py script) is used for post-upgrade cleanup but does not
stop ongoing updates.
Option C (Restarting Genesis) does not stop an LCM upgrade and can cause
instability.

C. Create a Project for each team lead and assign access.
D. Create Security Policies to isolate users.
Answer: C
Explanation:
The most efficient way to allow team leads to manage a specific set of VMs is by
creating a Project (Option C) in Prism Central and assigning the team leads to that
Project.
Nutanix Projects allow administrators to control VM access based on groups and
permissions, ensuring that users only manage VMs assigned to their project.
Option A (Role Mapping) applies more broadly to roles but does not restrict access to
specific VM groups.
Option B (VPC Admin) is related to network segmentation, not VM access control.
Option D (Security Policies) are used for network and firewall rules, not VM access
control.

10.An administrator needs to configure NTP on Prism Central running on a Hyper-V
cluster.
How should the administrator complete this task?
A. Add an external NTP server.
B. Add the DNS server IP.
C. Add a server with a DNS hostname.
D. Add the IP of the Domain Controller.
Answer: A
Explanation:
Nutanix requires that all cluster components synchronize time using an external NTP
(Network Time Protocol) server.
Option A (Adding an external NTP server) is correct because Nutanix best practices
recommend using an external time source to prevent clock drift between cluster
nodes.
Option B (DNS server IP) is incorrect: A DNS server does not provide NTP services.
Option C (Server with DNS hostname) is incorrect unless the DNS hostname resolves
to an NTP server.
Option D (IP of the Domain Controller) is incorrect because not all domain controllers
provide NTP
services unless explicitly configured.

11.Which two entities can be categorized? (Choose two.)
A. Storage Containers
B. Alerts
C. Virtual Machines
D. ISO Images
Answer: B, C
Explanation:
In Nutanix Prism Central, categories allow administrators to group and organize
entities for management, automation, and policy enforcement.
Alerts (Option B) can be categorized to group similar system events and create
filtering rules. Virtual Machines (Option C) can be categorized to apply security
policies, automation tasks, and resource allocation rules.
Option A (Storage Containers) cannot be categorized in Prism Central. Storage
policies apply at the container level but are not managed via categories.
Option D (ISO Images) cannot be categorized because ISOs are static objects, not
active entities.

12.What feature allows receiving a weekly message about infrastructure performance
summary?
A. Admin Center Life Cycle Manager
B. Prism Central Syslog
C. Infrastructure VMs List
D. Intelligent Operations Reports
Answer: D
Explanation:
Nutanix Intelligent Operations Reports (Option D) provide weekly summaries of
cluster health, performance, and resource consumption.
These reports include recommendations for optimization, alerts, and forecasted
resource usage trends.
Option A (Admin Center LCM) manages firmware and software upgrades but does
not generate weekly performance reports.
Option B (Prism Central Syslog) is used for logging and event tracking, not
performance summaries.
Option C (Infrastructure VMs List) provides a static list of VMs but does not generate
periodic reports.

13.Which storage attributes do Storage Policies manage?
A. Storage Containers and Volume Groups
B. Replication Factor and Encryption
C. Shares and Object Stores
D. Data Protection and Security
Answer: B
Explanation:
Storage Policies in Nutanix allow administrators to configure data protection and
performance settings at the storage container level.
Replication Factor (RF) defines the number of copies of data stored across nodes for
fault tolerance.
Encryption ensures that data at rest is protected via Nutanix-native encryption
methods.
Option A (Storage Containers and Volume Groups) refers to storage organization, not
policies.
Option C (Shares and Object Stores) applies to file and object storage services, not
VM storage policies.
Option D (Data Protection and Security) is a broad term but does not define specific
policy attributes.

Answer: C
Explanation:
When Life Cycle Manager (LCM) reports that a newer framework version is available,
the correct action is to perform an inventory scan (Option C).
Performing an inventory scan updates the available firmware/software versions and
allows LCM to download required updates.
Option A (Run an AOS upgrade) is unrelated to the LCM framework update process.
Option B (Run an AHV upgrade) is a separate component update and does not affect
the LCM framework.
Option D (Download manually from a CVM) is not necessary because LCM updates
are automatically pulled after an inventory scan.

15.An administrator needs to ensure that a VM is powered on before the rest of the
VMs when starting a host.
Which configuration option allows this behavior?
A. Recovery Plan
B. Host Affinity
C. High Availability
D. Agent VM
Answer: C
Explanation:
High Availability (HA) in Nutanix provides priority-based VM restart capabilities to
ensure that certain
VMs are powered on before others in the event of a host reboot or failure.
Option C (High Availability) is correct:
Nutanix HA policies allow administrators to prioritize VM startup order to ensure that
critical services (such as database VMs or management VMs) are available before
others.
Option A (Recovery Plan) is incorrect:
Recovery Plans are used in Disaster Recovery (DR) scenarios and do not control
boot order during normal host restarts.
Option B (Host Affinity) is incorrect:
Host Affinity is used to keep a VM pinned to a specific host, but it does not control
boot sequencing.
Option D (Agent VM) is incorrect:
Agent VMs (such as Witness VMs) are specialized virtual machines used for Metro
Availability, not
general boot priority settings.

16.An administrator is preparing for a firmware upgrade on a host and wants to
manually migrate VMs before executing the LCM upgrade. However, one VM is
unable to migrate while others migrate successfully.
Which action would fix the issue?
A. Enable Acropolis Dynamic Scheduling (ADS) at the cluster level.
B. Update Link Layer Discovery Protocol (LLDP).
C. Disable Agent VM within the VM configuration options.
D. Configure backplane port groups that are assigned to the CVM.
Answer: C
Explanation:
If a VM is unable to migrate, the most likely cause is that it is an Agent VM (such as a
Nutanix Witness VM or a VM with special dependencies).
Option C (Disable Agent VM) is correct:
Some Agent VMs are configured to prevent migration due to critical roles (e.g., a
Witness VM for Metro Availability).
Disabling Agent VM restrictions allows it to migrate before a host enters maintenance
mode.
Option A (Enable ADS) is incorrect:
Acropolis Dynamic Scheduling (ADS) helps with VM placement after migration, but it
does not force
an unmigratable VM to move.
Option B (Update LLDP) is incorrect:
LLDP is used for network discovery, but it does not impact VM migration behavior.
Option D (Configure backplane port groups) is incorrect:
Backplane settings impact CVM communication, not VM migration.

D. Configure a Protection Domain.
Answer: B
Explanation:
During failover in Nutanix Disaster Recovery, VMs retain their static IPs but may lose
DNS settings if the network configuration at the DR site is different from the primary
site.
Option B (Create custom in-guest scripts) is correct:
Custom scripts allow Windows or Linux VMs to restore DNS settings automatically
after failover.
These scripts can be executed using post-failover automation in Nutanix DR policies.
Option A (Self-Service Restore) is incorrect:
Self-Service Restore is used for end-user recovery of deleted files, not for network
settings.
Option C (nncli tool) is incorrect:
The nncli tool is used for network troubleshooting, but it does not automatically
restore DNS settings.
Option D (Configure a Protection Domain) is incorrect:
Protection Domains define replication policies, but they do not fix DNS settings after
failover.

18.An administrator needs to create a storage container named TestData with the
following conditions:
Replication Factor (RF) = 1 (RF1)
Inline Compression enabled
Deduplication disabled
Maximum storage capacity = 100 GiB
How should the administrator complete this task?
A. Log into Prism Element and create the storage container with an Advertised
Capacity of 100 GiB.
B. Log into Prism Element and create the storage container.
C. Log into Prism Central and create the storage container with a Reserved Capacity
of 100 GiB.
D. Log into Prism Central and create the storage container.
Answer: A
Explanation:
When creating a storage container in Nutanix, the administrator must configure the
correct capacity settings:
Option A (Prism Element with Advertised Capacity of 100 GiB) is correct:
Advertised Capacity defines logical limits for the container (i.e., how much space it
m
S

reports as available).
Inline Compression can be enabled directly in Prism Element.
Option B (Create in Prism Element without Advertised Capacity) is incorrect:
Without specifying Advertised Capacity, the container may consume unlimited
storage.
Option C (Create in Prism Central with Reserved Capacity) is incorrect:
Reserved Capacity applies to Quality of Service (QoS) policies, not storage limits.
Option D (Create in Prism Central without capacity limits) is incorrect:
Prism Central can manage storage but does not directly enforce RF1 and
compression policies.

19.Which predefined view in Prism Central’s Intelligent Operations should be used to
determine which VM is consuming excessive resources and causing performance
issues for others?
A. Inactive VMs List
B. Overprovisioned VMs List
C. Bully VMs List
D. Constrained VMs List
Answer: C
Explanation:
The Bully VMs List (Option C) in Prism Central’s Intelligent Operations identifies VMs
consuming excessive CPU, memory, or storage, which negatively affects other VMs.
Option A (Inactive VMs List) is used for identifying unused VMs but does not detect
performance issues.
Option B (Overprovisioned VMs List) helps identify VMs with excessive allocated
resources, but it does not focus on live performance impact.
Option D (Constrained VMs List) highlights VMs suffering from resource contention,
not those
causing it.

21.A user created a report in the Intelligent Operations Analysis Dashboard but forgot
to download it. However, after logging back into Prism Central, the administrator finds
that the report is no longer available.
What is the most likely cause?
A. A user with Cluster Viewer role deleted the report.
B. The user-generated report was archived.
C. Reports are automatically deleted after 24 hours.
D. The report is stored in the cluster’s Prism Element.
Answer: C
Explanation:
In Nutanix Prism Central, user-generated reports in Intelligent Operations are stored
for a limited time and then deleted automatically.
Option C (Reports are automatically deleted after 24 hours) is correct:
Reports do not persist indefinitely unless they are scheduled reports.
One-time reports expire after 24 hours.
Option A (Cluster Viewer deleted the report) is incorrect:
Cluster Viewer does not have permissions to delete reports.
Option B (Report was archived) is incorrect:
Nutanix does not automatically archive reports.

Explanation:
Metro Availability in Nutanix requires that the primary and secondary storage
containers be configured identically to ensure data replication consistency.
Option C (The destination storage container is not empty) is correct:
The remote storage container must be empty before Metro Availability can be
enabled.
Existing data can cause conflicts and prevent it from appearing in the "Compatible
Remote Sites" list.
Option D (Both storage containers must have the same name) is correct:
Metro Availability requires that storage containers have identical names across
clusters.
If names do not match, the storage container will not be listed as compatible.
Option A is incorrect: Metro Availability works regardless of hardware vendor
differences.
Option B is incorrect: Compression does not affect compatibility but may impact
performance.

CPU: 2x Intel Xeon Gold (8 cores, 2.6 GHz)
RAM: 256 GB per host
Storage: SSDs and HDDs
The Intelligent Operations feature has been active for one month, but no further
configurations were applied.
What does the dotted red line mean?
A. It is the default trend analysis static threshold that can be manually set.
B. It is the maximum memory the administrator can assign to VMs.
C. It is the calculated memory oversubscription limit for currently running VMs.
D. It is the usable capacity based on cluster configuration options.
Answer: D
Explanation:
he Prism Central Memory Cluster Runway Diagram provides insights into memory
usage trends, predicting how long the cluster can sustain workloads before
exhausting resources. The solid blue area represents the actual memory consumption
over time.
The dotted red line represents the effective memory capacity limit based on the
cluster's current configuration.
Analyzing the Dotted Red Line
The dotted red line is labeled "Effective Capacity: 503.22 GiB", which means:
It is the total usable memory capacity in the cluster after considering hypervisor
overhead, redundancy settings, and failover capacity.
This value is not a hard limit but an indication of the available memory before potential
performance issues occur.
Evaluating the Answer Choices
? (A) It is the default trend analysis static threshold that can be manually set.
(Incorrect) The dotted red line is not a static threshold that an administrator can
manually configure. Trend analysis in Prism is dynamic and based on workload
history and projections.
? (B) It is the maximum memory the administrator can assign to VMs. (Incorrect)
Administrators can oversubscribe memory beyond the dotted red line if memory
overcommitment is enabled.
However, oversubscribing memory beyond effective capacity may impact
performance.
? (C) It is the calculated memory oversubscription limit for currently running VMs.
(Incorrect) The dotted red line does not represent oversubscription limits.
Memory oversubscription depends on hypervisor memory ballooning, compression,
and swapping mechanisms, which are not directly shown here.
? (D) It is the usable capacity based on cluster configuration options. (Correct
Answer)
The dotted red line (503.22 GiB) represents the actual usable memory available in the
cluster after
factoring in system overhead.

Operations capacity analysis
Multicloud Infrastructure Reference & Best Practices
Prism Central’s "Runway" feature provides AI-driven trend analysis for memory,
CPU, and storage capacity.
The effective capacity limit helps administrators make proactive scaling decisions
before resources become critical.
To increase the memory runway, administrators can:
Optimize VM memory allocation.
Add more hosts to the cluster.
Enable memory deduplication and compression (if available).

24.An administrator receives complaints about VM performance.
After reviewing the VM’s CPU Ready Time data, which step should the administrator
take to diagnose the issue further?
A. Check the number of vCPUs assigned to each CVM.
B. Review host CPU utilization.
C. Assess cluster SSD capacity.
D. Enable VM memory oversubscription.
Answer: B
Explanation:
CPU Ready Time indicates how long a VM waits for CPU resources due to
contention.
Option B (Review host CPU utilization) is correct:
If CPU utilization is high, there may be excessive CPU overcommitment, leading to
high CPU Ready Time.
Adding more hosts or reducing vCPU allocations may resolve the issue.
Option A (Check CVM vCPUs) is incorrect:
The Controller VM (CVM) does not directly impact application VM performance in this
case.
Option C (Assess SSD capacity) is incorrect:
CPU Ready Time is unrelated to storage performance.
Option D (Enable VM memory oversubscription) is incorrect: Memory oversubscription
does not affect CPU contention.

Which AHV feature can be used to optimize network traffic so that multicast traffic is
only forwarded to the VMs that need to receive it?
A. LACP
B. UDP
C. IGMP Snooping
D. Network Segmentation
Answer: C
Explanation:
Multicast traffic can generate unnecessary overhead if it is not properly managed.
IGMP Snooping (Option C) ensures that multicast packets are only sent to VMs that
have requested them, rather than broadcasting to all VMs.
Option C (IGMP Snooping) is correct:
It reduces unnecessary multicast traffic by ensuring that only subscribed VMs receive
the packets.
It is supported natively in AHV networking.
Option A (LACP) is incorrect:
Link Aggregation Control Protocol (LACP) improves bandwidth and redundancy but
does not control multicast traffic.
Option B (UDP) is incorrect:
UDP (User Datagram Protocol) is a transport protocol, not a network optimization
feature.
Option D (Network Segmentation) is incorrect:
Segmentation (VLANs, VPCs) isolates networks but does not optimize multicast traffic
specifically.
