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?
Answer(s): A
Capacity Runway requires a minimum data history to project trends, and on a newly registered AHV cluster with only 16 days of data, there isn't sufficient data to generate projections. A) is correct because Capacity Planning needs at least 30 days of historical data to compute baseline runway accurately. B) and D) are incorrect since 21 or 6 months exceed the minimum and are not the threshold. C) is incorrect because 3 months (90 days) is more than 30 days but not the stated requirement; the actual minimum is 30 days, not 90.
An administrator is configuring a replication schedule on multiple remote locations deployed using a single-node cluster. The goal is to achieve the lowest possible RPO (Recovery Point Objective). How should the administrator configure the replication schedule?
Answer(s): C
Configure Async replication.A) NearSync is lower latency but requires synchronous links and is not suited for multiple remote locations with single-node clusters; it can impact RPO feasibility across sites. B) Scheduling 16–59 minutes yields higher RPO than tighter windows and does not guarantee near-zero data loss. C) Async replication provides non-blocking commits with configurable RPO, suitable for dispersed single-node clusters and achieving minimal data loss when links are unreliable. D) 1–15 minute scheduling would reduce RPO, but in practice, Nutanix async replication with appropriate RPO targets is used for multi-site single-node deployments; async is the correct approach to minimize data loss given constraints.
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?
https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Security-Guide-v6_10:mul- configure-data-in-transit-encryption-pc-t.html"Ensure that port 2009 is open between the Prism Central instances for the KMS cluster to communicate."This is explicitly stated in the "Firewall rules for Data-in-Transit Encryption" section for Prism Central.Technical Context:Port 2009 is used by ZooKeeper (the coordination service for the KMS cluster) in Scale-Out Prism Central deployments.DiTE in Prism Central relies on a dedicated KMS cluster that synchronizes encryption keys across PC instances using this port.Firewall blocks on port 2009 break KMS quorum, preventing key exchange and causing DiTE to fail.
A Disaster Recovery administrator has set up a Protection Policy for 50 workloads, all configured similarly.The RPO is 60 minutes with a specified retention of 10 local copies, 5 remote copies, and crash consistency.After activation, recovery points are not appearing at the DR site, even though they are visible on the production side.What is the most likely issue?
For Disaster Recovery to function correctly, the source and destination storage containers must have identical names.Option C (Storage container name mismatch) is correct:If the storage container name at the DR site does not match, Nutanix cannot map snapshots and replication data.This causes failover operations to fail, even though data exists.Option A (NGT not installed) is incorrect:NGT is needed for application-consistent snapshots, but not required for crash-consistent snapshots.Option B (Windows updates) is incorrect:OS updates do not affect replication availability.Option D (Storage RF factor mismatch) is incorrect:Replication works across different RF factors, but performance may vary.

An administrator needs to optimize a VM's storage by leveraging compression features. The VM's vDisks are currently stored in a default storage container with no optimizations enabled.How should the administrator proceed?
Moving vDisks to a storage container with compression enabled ensures better data efficiency without downtime.Option A (Migrate vDisks) is correct:vDisk migration is non-disruptive and allows compression settings to be applied dynamically.Option B (Recreate the VM) is incorrect:Rebuilding the VM is unnecessary and would cause downtime.Option C (Migrate the VM) is incorrect:VM migration does not guarantee that only vDisks move, and it may disrupt performance.Option D (Recreate vDisk) is incorrect:This method is manual and time-consuming, while Nutanix provides an automated approach.

Which two URLs must be accessible from a Connected Site's Controller VMs to allow Life Cycle Manager (LCM) to download software updates?
Answer(s): A,C
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 needs to create a storage container for VM disks. The container must meet the following conditions:10 GiB of the total allocated space must not be used by other containers. The container must have a maximum storage capacity of 500 GiB. What settings should the administrator configure while creating the storage container?
Answer(s): D
Nutanix storage containers allow administrators to configure capacity reservations and advertised limits for better resource management.Option D (Set Reserved Capacity to 10 GiB and Advertised Capacity to 500 GiB) is correct:Reserved Capacity ensures that 10 GiB is always available for this container and not consumed by other containers.Advertised Capacity defines a logical limit of 500 GiB to prevent over-allocation.Option A is incorrect:Advertised Capacity of 10 GiB is too low and does not match the requirement of a 500 GiB storage container.Option B is incorrect:Only setting Advertised Capacity does not guarantee Reserved Capacity, meaning other containers could consume the reserved space.Option C is incorrect:Setting only Reserved Capacity does not enforce an upper limit, which could lead to overprovisioning.

In a five-node cluster, an administrator noticed that three VMs are consuming too many resources on a single host.Acropolis Dynamic Scheduling (ADS) is not able to migrate these VMs. What is the most likely reason preventing ADS from migrating these VMs?
Answer(s): B
VMs using GPU pass-through cannot be live-migrated because they are directly tied to a physical GPU on a specific host.Option B (VMs use GPU pass-through) is correct:Pass-through devices (such as GPUs) are directly assigned to VMs, making migration impossible unless the VM is powered off first.Option A (VMs use a Volume Group) is incorrect:Volume Groups support live migration unless they are configured incorrectly.Option C (VM-VM anti-affinity) is incorrect:Anti-affinity rules prevent two specific VMs from running together, but do not prevent migration.Option D (VMs use external NAS) is incorrect:Using NAS does not block VM migration, as Nutanix supports shared storage across hosts.
