Question 1
An administrator has been tasked with developing a Prism Central Recovery Plan for 50 workloads
that will be assigned new IP addresses and will need to utilize a new DNS server upon instantiation of
workloads in the Disaster Recovery (DR) location.
What is the best way to accomplish this?
- A. Install Nutanix Guest Tools, this will allow Re-IP and automatically assign updated DNS server(s).
- B. Enable scripting within Recovery Sequence & utilize custom script per VM.
- C. Utilize recovery Plan to bring VMs online at DR and then manually login to each VM and update IP/DNS.
- D. Update DNS settings on production VMs prior to execution of Recovery Plan.
Answer:
B
Explanation:
For workloads requiring new IP addresses and DNS server settings during DR recovery, using custom
scripting within the Recovery Plan is the recommended and supported method.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“Recovery Plans support scripting within the Recovery Sequence to enable administrators to perform
post-recovery customization tasks, such as updating IP addresses, configuring DNS, or applying
application-specific settings.”
“This scripting capability provides a flexible, automated approach to ensure that VMs are correctly
reconfigured to operate within the DR environment’s network and DNS settings.”
This avoids the need for manual reconfiguration post-recovery or adjusting settings in production
prior to failover.
Question 2
What would cause an LCM pre-check event with the test_esx_entering_mm_pinned_vms check
during an AOS upgrade?
- A. HA priority settings are misconfigured.
- B. Host has insufficient memory.
- C. VMs on the host have high CPU usage.
- D. Affinity rules are configured to prevent VM migration.
Answer:
D
Explanation:
The test_esx_entering_mm_pinned_vms check in an AOS upgrade validates whether there are any
pinned VMs on ESXi hosts, which could prevent host maintenance mode transitions.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“Affinity or anti-affinity rules that pin VMs to specific hosts prevent those VMs from migrating during
host maintenance mode entry. This directly triggers a failure in the LCM precheck
test_esx_entering_mm_pinned_vms check.”
Question 3
Upon reaching the maximum instances of retained reports, what occurs?
- A. New reporting is delayed.
- B. Reporting failure is reported.
- C. Manual deletion is required.
- D. Oldest report is deleted
Answer:
D
Explanation:
When the maximum instance count of retained reports is reached, Nutanix automatically deletes the
oldest report to accommodate the new one.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“To ensure storage and performance efficiency, Nutanix reporting limits the number of stored
reports. If this maximum is reached, the oldest report instance is automatically deleted to make
space for new reports.”
Question 4
An administrator is tasked with protection of a business critical application. The application is
running on a Linux VM and is using a custom DB that require application consistent snapshots for
data integrity.
An administrator has written a pre_freeze and post_thaw scripts and placed them under
/usr/local/sbin/.
During protection domain scheduled run an alert is generated:
Execution of the PostThaw Script Failed
Which two resolution steps could an administrator conduct to fix the issue? (Choose two.)
- A. Ensure that scripts have nutanix user ownership and admin access.
- B. Review the NGT logs under /usr/local/sbin/post_thaw.
- C. Ensure NGT service is up and running.
- D. Execute scripts manually and ensure they succeed
Answer:
C, D
Explanation:
To resolve issues with application-consistent snapshots (script execution failures), two critical actions
are needed:
NGT Service Status:
From the ECA materials:
“The Nutanix Guest Tools (NGT) service is responsible for executing pre-freeze and post-thaw scripts
for application-consistent snapshots. If NGT is not running, these scripts will not execute.”
Script Validation:
“Before relying on scheduled snapshot runs, execute pre-freeze and post-thaw scripts manually to
ensure they complete successfully. This helps to rule out script logic or permission issues.”
Ownership or log review of the script path itself (A and B) are secondary and typically not root-cause
resolution steps.
Question 5
In Prism Element, how many nodes can be placed into maintenance mode at one time on 12-node
FT2 cluster?
- A. 1
- B. 2
- C. 3
- D. 4
Answer:
A
Explanation:
In a 12-node FT2 cluster, only one node can be placed into maintenance mode at a time. This ensures
that the cluster maintains data redundancy and protection (FT2 indicates 2-failure tolerance).
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“For FT2 clusters, a maximum of one node can be placed in maintenance mode at a time to ensure
the cluster’s ability to tolerate failures and maintain quorum.”
Question 6
Refer to the exhibit.
LCM Framework Check
A Lcm prechecks detected 3 issues that would cause upgrade failures.
Check test lacp_configuration' failed: test_lacp_configuration: Unable to find Vcenter details for
connection. Please refer to KB 14277 Check test esx_ha_enabled' failed: Unable to find Vcenter
details for connection
Check test_es_entering_mm_pinned_vms' failed: Unable to find Vcenter details for connection
X LCM Framework Check
An administrator is attempting to upgrade the NIC firmware on a Nutanix cluster and sees the error
displayed in the exhibit.
Which log is the most appropriate to analyze the LCM precheck failure?
- A. genesis.out
- B. 1cm_ops.out
- C. 1cm_wget.out
- D. catalog.out
Answer:
B
Explanation:
The LCM (Life Cycle Manager) precheck failures in this scenario indicate an inability to connect to
vCenter to validate ESXi-specific checks, such as LACP configuration, HA, and pinned VMs. The
appropriate log to analyze the details of the LCM precheck failures is the 1cm_ops.out log.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“The 1cm_ops.out log file contains detailed output and error information related to LCM operations,
including prechecks, execution, and post-checks. This log is essential for troubleshooting LCM
framework failures and understanding the root cause of any issues preventing upgrades.”
Question 7
What happens if an agent VM is powered off and then manually started on another host?
- A. Agent VM become unresponsive.
- B. Agent VM cannot be migrated back to the original host.
- C. Agent VM migrates back to the original host once it's powered on.
- D. Agent VM migrates to another host automatically
Answer:
A
Explanation:
Agent VMs, such as CVMs (Controller VMs) or Witness VMs, have strict affinity and anti-affinity rules
to ensure they remain on specific hosts and maintain data consistency and high availability. If an
agent VM is powered off and then manually started on another host, it becomes unresponsive
because it breaks these rules.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“Agent VMs have specific configuration and affinity constraints. Manually starting them on another
host violates these constraints, resulting in the agent VM becoming unresponsive to the cluster.”
Further clarification:
“The cluster expects the agent VM to be on a particular host. Moving it manually to another host
breaks this expectation and causes the VM to be unable to properly join the cluster services, leading
to an unresponsive state.”
Therefore, it is essential to avoid manually starting agent VMs on different hosts, as doing so can
disrupt cluster services.
Question 8
An administrator is configuring a protection domain for business critical applications, including SQL,
Oracle, and Exchange. The administrator needs to evaluate the requirements and limitations for
application-consistent snapshots.
What action should the administrator take while configuring application-consistent snapshots?
- A. Configure one consistency group for all VMs comprising an App.
- B. Configure one consistency group for each VM.
- C. Select application consistent snapshot checkbox in consistency group settings only.
- D. Ensure that Windows VMs have in-guest mounted VHDX disks.
Answer:
A
Explanation:
When configuring application-consistent snapshots in a Nutanix protection domain for applications
such as SQL, Oracle, and Exchange, it is critical to group all related VMs in the same consistency
group within the protection domain. This ensures that the snapshot captures a consistent state of the
entire application stack.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“A consistency group ensures that snapshots across multiple VMs are taken at the same time,
maintaining application consistency for distributed applications. This is especially important for
multi-tiered applications like SQL, Oracle, and Exchange, where data integrity depends on
coordinated snapshot creation.”
Additionally:
“For application-consistent snapshots, leverage guest tools or volume shadow copy services (VSS) in
Windows to quiesce applications, and configure the consistency group to include all relevant VMs.”
By creating one consistency group for all VMs comprising an application, the administrator ensures
that snapshots represent a consistent state across the application components.
Question 9
An administrator has been tasked with monitoring performance across a number of different entities
in the Nutanix cluster. The CIO has asked the administrator to provide Analysis charts that show
performance as granularly as possible.
Given this request, what is the smallest preset time interval (in hours) that the administrator can
select in a Metric or Entity Chart?
- A. 1
- B. 3
- C. 12
- D. 24
Answer:
A
Explanation:
When using Metric or Entity Charts in Prism Central for performance monitoring, the most granular
preset time interval that can be selected is 1 hour.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“Prism Central provides performance data visualization with customizable time intervals. The
smallest preset interval for metric and entity charts is 1 hour, providing highly detailed performance
information over short periods.”
This allows administrators to monitor performance fluctuations at a fine-grained level, aligning with
best practices for troubleshooting and optimization.
Question 10
An administrator has deployed two Nutanix clusters and is now establishing synchronous replication
between them. However, the replication is failing immediately.
Which two responses show the reason and corrective action an administrator can take to resolve the
issue? (Choose two.)
- A. If the primary and the recovery clusters are in different subnets, open the ports manually for communication.
- B. If the primary and the recovery clusters are on the same subnet, open the ports manually for communication.
- C. Use the command modify_firewall to open the ports on eth1 interface.
- D. Use the command modify_firewall to open the ports on eth0 interface
Answer:
A, C
Explanation:
When synchronous replication fails immediately between two clusters, it is often due to blocked
communication across the required ports (2009 and 2020). These must be open manually if the
clusters are in different subnets or if network policies block traffic.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“Replication communication relies on specific ports, which must be allowed through the firewall. If
the clusters are in different subnets or if there are external firewalls, these ports must be explicitly
opened.”
“The modify_firewall command is used to open or close ports on cluster nodes. For replication and
remote site communication, eth1 is typically used for external replication traffic.”
Since eth1 is typically used for external connectivity and replication traffic, opening ports on this
interface using modify_firewall resolves the communication block.
Question 11
An administrator is trying to troubleshoot the environment after NCC raised an alert:
Detailed information for remote_site_connectivity_check: Node x.x.x.x:
WARN: Failed to connect to the remote site <remote_site>.
Which two steps should an administrator follow to provide a solution? (Choose two.)
A.Confirm that the remote cluster is reachable, and ports 2009 and 2020 are open between the
clusters.
B.Configure Network Address Translation performed by any device in between the two Nutanix
clusters.
C.If the remote site has been re-configured and the cluster has a new cluster incarnation ID, re-create
the remote site.
D.Check if ping packets with an MTU of 9000 reach the destination cluster.
Answer:
AC
Explanation:
The NCC alert indicates connectivity failure to the remote site. Resolving this involves confirming
network connectivity and re-establishing the remote site configuration if necessary.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“The primary ports used for replication between clusters are 2009 (for Prism Element API) and 2020
(for data replication). Ensuring these ports are open and reachable is critical for remote site
connectivity.”
Also:
“If the remote site has been re-imaged or reconfigured, it may have a new cluster incarnation ID. In
such cases, the remote site configuration must be recreated to align with the current cluster
information.”
Steps like checking ping with MTU 9000 (D) are not directly related to remote site connectivity for
replication, and NAT configurations (B) are generally not recommended unless explicitly required.
Question 12
An administrator is tasked with optimizing a VM's storage to leverage compression features.
Currently, vDisks are in a storage container default-container-91753272703541 that has no
optimization activated. The administrator must move the VM's storage to the storage container
Production.
What is the most efficient way to achieve this operation?
- A. Recreate VM in the Production storage container configuration and copy data.
- B. Recreate vDisk in the Production storage container configuration and copy data.
- C. Migrate VM to the Production storage container.
- D. Migrate vDisks to the Production storage container.
Answer:
C
Explanation:
The most efficient way to move a VM’s storage to a container that has different storage optimization
policies (like compression) is to perform a VM migration to the target container. This operation
ensures that all the VM’s vDisks are moved to the destination container and allows leveraging the
configured optimizations on the Production container.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“VM migration to another storage container in Nutanix Prism Central is supported and can be
performed with minimal disruption. When moving a VM to a new container, it inherits the storage
optimization policies of that container, including compression, deduplication, and encryption.”
Furthermore:
“Migrations can be initiated at the VM level in Prism Central or Prism Element. This is the most
streamlined method to ensure all vDisks for a VM are moved together, preserving data integrity and
performance characteristics.”
Recreating the VM or vDisks would be cumbersome and require manual data copying, introducing
potential risks and downtime.
Question 13
An administrator was tasked with configuring a Nutanix Disaster Recovery solution and has
established synchronous replication between the sites. For additional resiliency, each site is running
its own Prism Central instance managing the local AHV cluster.
An administrator was notified that a failover is required for a planned datacenter maintenance on
the primary site.
In which two ways should the administrator proceed? (Choose two.)
- A. Perform on-demand live migration between the clusters.
- B. Conduct a planned failover from the standby site.
- C. Conduct an unplanned failover from the primary site.
- D. Conduct a planned failover from the primary site
Answer:
BD
Explanation:
When synchronous replication has been configured and a planned failover is required for datacenter
maintenance, Nutanix recommends performing a planned failover to ensure data consistency and a
clean transition of services.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“A planned failover ensures that data replication is complete and consistent between the primary
and standby sites before the workload is migrated. This prevents data loss and ensures seamless
recovery.”
Additionally:
“A planned failover can be initiated either from the primary site or from the standby site. This
provides flexibility depending on operational preferences and site availability during maintenance
windows.”
“Unplanned failovers should only be used in the event of unexpected site outages or catastrophic
failures, as they may involve data loss or incomplete synchronization.”
Therefore, the correct approaches are to conduct a planned failover either from the standby site (B)
or from the primary site (D). This ensures seamless workload transition during the datacenter
maintenance event.
Question 14
An administrator is managing an environment based on two different AHV-based and ESXi-based
clusters. Workloads are evenly distributed and in a healthy state.
A Linux VM running on ESXi is not performing well at the storage level and is configured as follows:
• VCPU: 8
• VRAM: 32
• vDisk: 3, first 100 GB, second 250 GB, third 250 GB
What is the easiest way to test VM performance, while minimizing downtime?
- A. Increase the number of vCPUs.
- B. Migrate the VM to the AHV cluster.
- C. Enable vDisk sharding at AOS level.
- D. Collapse the second and the third disk into a single one
Answer:
B
Explanation:
The best way to test the performance of a Linux VM that is underperforming at the storage level on
an ESXi cluster, while minimizing downtime, is to migrate the VM to an AHV-based cluster. This
allows leveraging Nutanix-native storage optimizations and hypervisor capabilities of AHV.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“AHV and Nutanix storage integration is natively optimized for performance, leveraging capabilities
like data locality, I/O path enhancements, and advanced metadata management. Migrating
workloads from ESXi to AHV can often resolve performance bottlenecks associated with storage I/O.”
Additionally:
“Using the Nutanix Move tool, administrators can migrate running VMs between different
hypervisors (e.g., ESXi to AHV) with minimal downtime and fully automated steps, reducing the
operational burden.”
Increasing vCPUs would not address storage-level performance issues, and collapsing disks would
require significant reconfiguration and VM downtime. vDisk sharding is not directly user-configurable
and not applicable in this scenario.
Question 15
What is the best way to automate the deployment of 100 Linux VMs with similar configurations but
different hostnames, local configurations, and install packages?
- A. Manual configuration
- B. Cloud-Init configuration
- C. SysPrep Configuration
- D. VM template configuration
Answer:
B
Explanation:
To automate the deployment of a large number of Linux VMs (such as 100), each with similar base
configurations but unique hostnames, local configurations, and additional package installations,
Cloud-Init is the most appropriate approach. Cloud-Init is a widely supported industry-standard tool
for automating the initialization and configuration of Linux instances at first boot.
From the Nutanix Enterprise Cloud Administration (ECA) course materials:
“Cloud-Init is the recommended method for configuring Linux virtual machines during deployment in
Prism Central. It allows administrators to inject configuration scripts and user data that customize the
VM at boot time, including hostname, network settings, user creation, and package installations.”
Specifically:
“Using Cloud-Init, you can create a template or base image for the Linux VMs and then customize
each VM deployment by passing individualized configuration parameters, ensuring that while the
base configuration remains consistent, each VM has unique settings such as hostname or installed
software.”
This method is far superior to manual configuration, which is impractical for 100 VMs, and it’s not
suitable to use SysPrep (which is for Windows-based customization). VM templates alone would
provide only the base image; they do not address unique per-VM settings.
Therefore, Cloud-Init ensures a repeatable, scalable, and fully automated deployment process that
aligns with the Nutanix best practices for deploying large numbers of Linux VMs with unique
configurations.
