An administrator received a request to create a new storage container for persistent desktops.
Which storage optimization setting must the administrator set for the best possible capacity savings?
- A . Erasure Coding
- B . Inline compression with a delay of 0 minutes
- C . Inline Deduplication of Read Caches
- D . Post Process Deduplication
Which task should be performed first when upgrading host memory?
- A . Gracefully stop the host by using the out of band management interface.
- B . Remove node from the cluster.
- C . Execute "shutdown -h now" from the AHV command line interface.
- D . Place node into the maintenance mode
An administrator has been asked to calculate baseline Capacity Runway on a newly registered AHV cluster.
The cluster has been running for 16 days, but no runway projections are displayed.
Why are no Capacity Runway projections being displayed?
- A . Capacity Planning requires at least 30 days of data.
- B . Capacity Planning requires at least 21 days of data.
- C . Capacity Planning requires at least 3 months of data.
- D . Capacity Planning requires at least 6 months of data.
A
Explanation:
Nutanix Prism Central requires at least 21 days of usage data to generate accurate Capacity Runway projections.
Option B (21 days) is correct:
Until 21 days of data is collected, no runway analysis is available.
Option A (30 days) is incorrect:
30 days is recommended for long-term accuracy, but not required for initial projections.
Option C (3 months) and Option D (6 months) are incorrect:
Extended data collection helps trend accuracy, but runway calculations begin after 21 days.

An administrator attempted to enable Data-in-Transit Encryption on a Scale-Out Prism Central cluster to encrypt service-level traffic between nodes. However, the feature did not work correctly due to a firewall restriction.
Which CVM-specific port should be allowed through the firewall for Data-in-Transit Encryption?
- A . 2009
- B . 2010
- C . 2020
- D . 9440
C
Explanation:
Data-in-Transit Encryption in Nutanix requires inter-node communication over specific CVM ports.
Option A (Port 2009) is correct:
Port 2009 is used for Data-in-Transit Encryption between Nutanix CVMs.
Firewall rules must allow traffic on this port to enable secure encrypted communication.
Option B (Port 2010) is incorrect:
Port 2010 is used for CVM-to-CVM communication but does not handle encryption.
Option C (Port 2020) is incorrect:
This port is used for Acropolis File Services (AFS), not encryption.
Option D (Port 9440) is incorrect:
Port 9440 is used for Prism Central web access, not internal CVM encryption.

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
Refer to Exhibit:
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.
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.

Which two URLs must be accessible from a Connected Site’s Controller VMs to allow Life Cycle Manager (LCM) to download software updates?
- A . download.nutanix.com
- B . mynutanix.com
- C . release-api.nutanix.com
- D . portal.nutanix.com
A, C
Explanation:
LCM (Life Cycle Manager) fetches software updates from Nutanix’s repositories, requiring access to specific URLs.
Option A (download.nutanix.com) is correct:
This domain hosts all software update files for AOS, AHV, and other Nutanix components.
Option C (release-api.nutanix.com) is correct:
This domain is used for LCM to fetch update metadata and check for new versions.
Option B (mynutanix.com) is incorrect:
This domain is used for account management, not LCM updates.
Option D (portal.nutanix.com) is incorrect:
The Nutanix support portal is not used for automated LCM updates.

An administrator wants to ensure that DR snapshots are protected from inadvertent or malicious deletion without notification.
What would be the best way to accomplish this?
- A . Create and Apply an Approval Policy.
- B . Create and Apply an Alert Policy.
- C . Assign DR Admin Role to users.
- D . Create a Playbook to alert on event
An administrator migrated a physical MySQL database from a legacy 3-tier environment to a Nutanix cluster.
After migration, the administrator finds that at peak load, the number of IOPS is lower than expected, and latency is higher.
Which two steps should the administrator take to improve performance? (Choose two.)
- A . Ensure that the SQL data vDisks are thick provisioned.
- B . Create additional vDisks for SQL data.
- C . Use LVM to stripe the SQL data across multiple vDisks.
- D . Ensure that the SQL data vDisks are thin provisioned.
B, C
Explanation:
For high-performance databases like MySQL, optimizing storage access is critical.
Option B (Create additional vDisks for SQL data) is correct:
Multiple vDisks allow better parallelism in Nutanix DSF (Distributed Storage Fabric), improving IOPS.
Option C (Use LVM to stripe SQL data across multiple vDisks) is correct:
Striping across multiple disks distributes the load, reducing latency.
Option A (Thick provisioned vDisks) is incorrect:
Nutanix always provisions vDisks thinly, and thick provisioning does not improve IOPS.
Option D (Thin provisioned vDisks) is incorrect:
All Nutanix vDisks are thin-provisioned by default.

Which two actions occur by default on a node that is placed in Maintenance Mode? (Choose two.)
- A . Non-migratable VMs are powered off and restarted on other hosts in the cluster.
- B . All eligible VMs on the host are migrated to other hosts in the cluster.
- C . All eligible VMs on the host are powered off.
- D . Non-migratable VMs are powered off.
B, D
Explanation:
When a node is placed into Maintenance Mode, Nutanix follows a structured process to ensure service continuity and data integrity.
Option B (All eligible VMs on the host are migrated to other hosts) is correct:
Live Migration automatically moves VMs to other hosts to avoid downtime.
This ensures workloads remain operational during maintenance.
Option D (Non-migratable VMs are powered off) is correct:
Some VMs, such as those using GPU pass-through or local storage dependencies, cannot be live-migrated.
These VMs must be powered off before placing the host into Maintenance Mode.
Option A is incorrect:
Non-migratable VMs are not automatically restarted on other hosts―they remain powered off until manually restarted.
Option C is incorrect:
Eligible VMs are live-migrated, not powered off.
