To remove old VM snapshots, the task should be completed from theVM dashboardin Prism Element. This dashboard allows administrators to manage virtual machine-related operations, including snapshot creation, deletion, and restoration. Steps include:

Navigate toPrism Element > VM.

Select the VM for which snapshots need to be deleted.

Click onSnapshots, then delete the selected snapshots.

On a newly deployed AHV cluster, the default uplink bond type for the virtual switch (vs0) isBalance-SLB (Source Load Balancing). This configuration balances traffic across the uplink interfaces based on the source of the traffic, ensuring optimal usage of available network bandwidth without requiring LACP configuration on the physical switches.

Redundancy Factor 3 (RF3) requires a minimum of five nodes in the cluster to ensure that data can be distributed across enough nodes to tolerate the failure of two nodes. If the cluster has fewer than five nodes, RF3 cannot be enabled.

A. Check that the cluster has been properly licensed:Licensing is not directly related to enabling RF3.

B. Check that the cluster has five or more nodes:Correct, as RF3 requires at least five nodes.

C. Check hardware availability of the nodes:While hardware health is important, it does not determine RF3 eligibility.

D. Check AOS version and upgrade, if needed:RF3 requirements are not specific to an AOS version.

For a cluster withRedundancy Factor 2 (RF2), at least4 nodesare required to configure Erasure Coding. Erasure Coding (EC) distributes data and parity across nodes to improve storage efficiency while maintaining data protection. RF2 requires a minimum of 4 nodes to ensure sufficient space for data and parity distribution.

Other options:

3 nodes: Insufficient for EC with RF2.

5 and 6 nodes: Can support EC, but the minimum requirement is 4.

Non-migratable VMs in a Nutanix cluster typically include those with attached Volume Groups. This is because such VMs leverage direct-attached storage via iSCSI, which ties them to a specific host, preventing live migration to another host. Volume Groups provide block storage to applications, and the iSCSI protocol does not support live migration of such connections.

Here's a breakdown of the options:

A. VMs without NGT:Nutanix Guest Tools (NGT) are used for guest-level integration but do not affect VM migratability.

B. VMs marked as an Agent:This setting does not inherently make VMs non-migratable. It primarily affects roles and tasks within certain configurations.

C. Memory Overcommitted:While memory overcommitment can affect performance, it does not make VMs non-migratable. Nutanix AHV handles memory allocation dynamically.

D. VMs with attached Volume Groups:Correct answer, as the iSCSI connections used by Volume Groups are host-specific and cannot migrate seamlessly.

Replication Factor (RF) defines the number of copies of data stored in a Nutanix cluster. RF2 ensures two copies of data, and RF3 ensures three copies. This redundancy allows the system to maintain data integrity and recoverability even in the event of hardware failures.

A. It limits the scope of hardware failures during recovery operations:Incorrect, as RF focuses on data replication, not limiting failure scopes.

B. It ensures that multiple copies of data are available for recovery:Correct, as RF directly relates to data redundancy and recovery capabilities.

C. It accelerates data transfer to remote backup sites:Incorrect, as RF does not affect remote backup speed.

D. It reduces the need for offsite backup solutions:Incorrect, as RF works within the cluster, not as a replacement for offsite backups.

Shared storage for Windows Server Failover Clustering (WSFC) is a use case for NutanixVolumes. Nutanix Volumes provides block storage (via iSCSI) to external systems, such as WSFC nodes, allowing them to share storage for failover clustering. This configuration is essential for high availability in Windows environments.

Other options:

Files: Provides file-based storage (NFS/SMB), not suited for WSFC shared block storage.

FT1 and RF2: Refer to Fault Tolerance and Redundancy Factor, not storage solutions.

Deduplication is most effective withfull clone VMsbecause it reduces redundant data blocks stored on the cluster. Full clone VMs often contain identical OS and application files, making them ideal candidates for deduplication, which optimizes storage usage and improves efficiency.

Other options:

Server workloads: May benefit from deduplication but not as significantly as full clone VMs.

Linked Clone VMs: Already share base disk images, so deduplication offers limited benefits.

Cold data: Deduplication is less effective for data that isn’t accessed frequently.

To allow Nutanix Support to gather logs automatically without requiring manual intervention, the administrator should enablePulse. Pulse is a telemetry service that collects and sends system health, log, and usage data to Nutanix Support securely.

Steps:

Navigate toPrism Central > Settings > Pulse.

Enable the service and configure as required for your environment.

Other options:

Self-Service: Refers to role-based access for users, unrelated to log collection.

Proxy Server: Used for network communication, not log gathering.

NKP: Refers to Nutanix Cluster Protocol, unrelated to telemetry.

Nutanix AHV (Acropolis Hypervisor) supports integrated IP address management (IPAM) as a built-in feature. IPAM allows administrators to dynamically allocate and manage IP addresses for VMs within a network segment. This functionality simplifies network management by automating the assignment of IPs without relying on external DHCP servers.

A. ESXi:Incorrect, as ESXi does not include built-in IPAM.

B. Hyper-V:Incorrect, as Hyper-V lacks integrated IPAM functionality.

C. AHV:Correct, as AHV has built-in IPAM for automated IP address allocation.

D. XenServer:Incorrect, as XenServer does not support integrated IPAM.

The correct answer isD. Flow Virtual Networking (FVN).

Flow Virtual Networking (FVN)is a Nutanix solution that enablesadvanced network virtualization, including:

VPCs (Virtual Private Clouds)

Overlapping IP address spaces

Self-service network provisioning

Multi-tenancy support

Microsegmentation

FVN abstracts physical networking and allows tenants to manageisolated logical networks, providing cloud-like networking capabilities directly integrated with AHV.

Clarifications:

A. Nutanix Kubernetes Platform (NKP):Orchestrates containers; does not provide virtualized network infrastructure.

B. Flow Network Security:Focuses onmicrosegmentationandpolicy enforcement, not on VPC or L3 abstraction.

C. Nutanix Database Service (NDB):Manages DBaaS; not related to networking.

Excerpt: “Flow Virtual Networking provides VPCs, overlapping IPs, and self-service networking capabilities for secure multi-tenancy in Nutanix AHV clusters.”

Answer: D

Nutanix Metro Availability provides the best Recovery Time Objective (RTO) because it enables synchronous replication between two sites. In the event of a failure at one site, VMs can be instantly restarted on the other site with minimal disruption. This setup ensures zero data loss and near-instantaneous recovery.

A. Async:Provides high RPO (Recovery Point Objective) but has a longer RTO compared to synchronous replication methods.

B. Availability Zone:This term refers to a general site setup, not specific to recovery objectives.

C. Metro Availability:Correct, as it uses synchronous replication for near-zero RTO.

D. NearSync:Provides better RPO than Async but does not match the RTO of Metro Availability.

The correct answer isB. Acropolis Dynamic Scheduling (ADS).

Acropolis Dynamic Scheduling (ADS)is a core component in Nutanix AOS responsible for:

Monitoring real-time resource utilization.

Identifying hotspotssuch as CPU/memory/storage contention.

LCM automates and orchestrates upgrades for components like BIOS, hypervisors, firmware, and Nutanix software, ensuring that the cluster remains up-to-date with minimal manual intervention.

A. To optimize server performance:Incorrect, as LCM focuses on updates, not performance optimization.

B. To manage network configurations:Incorrect, as LCM is unrelated to network configuration management.

C. To simplify software and firmware upgrades:Correct, as LCM is specifically designed for this purpose.

D. To automate application deployment:Incorrect, as LCM does not handle application deployment.

To rerun only the health checks that previously failed or issued warnings, the administrator can select theOnly Failed and Warning Checksoption in Prism Element. This targeted approach helps verify that resolved issues have been addressed without rerunning all checks unnecessarily.

Steps:

Navigate toPrism Element > Health > NCC Checks.

Filter forOnly Failed and Warning Checksand rerun them.

Other options:

A. Run LCM Pre-Upgrade: Runs pre-upgrade checks, not related to health check validation.

B. Runncc health_checks run_all: Executes all checks, not just failed ones.

C. Select Run Check for each check worked: Requires manual execution for each check.

The correct answer isB. Disabled.

When creating a new storage container in Prism Element or Prism Central,compression is disabled by default. The administrator mustexplicitly enableone of the available compression options:

Inline Compression

Post-process Compression

If no compression type is selected, the container remains uncompressed.

UI Navigation Path:

Excerpt: “NCC auto-update is available when Pulse is enabled, allowing Nutanix to deliver updated NCC versions directly to the cluster.”

Answer: C

Nutanix Distributed Storage Fabric (DSF) provides storage access to an ESXi hypervisor using theNFS (Network File System)protocol. DSF abstracts the underlying storage hardware and exposes storage as an NFS datastore to ESXi hosts. This integration enables high performance, data protection, and scalability while simplifying storage management.

Other options:

LVM: Not used in Nutanix storage.

iSCSI: Used for specific use cases, not the default protocol for ESXi.

SMB: Not supported for ESXi environments.

The correct answer isB. Active/Backup.

Foredge environmentswith limited uplink capacity, such as1GbE, the recommended bond mode isActive/Backupdue to the following reasons:

Providesredundancywithout requiring link aggregation support from the upstream switch.

Avoids complexity and performance imbalance that can occur with hashing algorithms in other modes (e.g., Balance-SLB).

Round RobinandBalance-SLBcan causepacket reordering, performance issues, and are not ideal for low-throughput links.

Prism Element Configuration Path:

Network Configuration > Host NIC Bonding Mode

Official Reference:

Nutanix Network Best Practices Guide – Edge Deployment Section

Excerpt: “For clusters using 1GbE uplinks, Active/Backup bond mode is recommended for high availability without complexity.”

Answer: B

TheRecycle Binin Nutanix clusters temporarily stores deleted VMs for 24 hours, allowing administrators to recover them if needed. This feature helps protect against accidental deletions by providing a grace period for recovery before permanent deletion occurs.

A. Stores the OpLog's most recent deleted data in case of a CVM failure:Incorrect, as the OpLog pertains to write operations, not VM deletion.

B. Keeps deleted VMs for 24 hours for recovery:Correct, as the Recycle Bin's purpose is temporary VM recovery.

C. Allows administrators to undo the last five actions:Incorrect, as there is no such feature for undoing multiple actions in Prism.

D. Centralizes the deleted data from the different VMs in the cluster:Incorrect, as the Recycle Bin is specifically for deleted VMs, not generalized data centralization.

The correct answer isC. It must have the same hypervisor as the other nodes in the cluster.

When adding astorage-only (SO) nodeto a Nutanix cluster:

It mustrun the same hypervisoras the existing nodes.

The SO node doesnot host VMsbut participates in thestorage layerto increase capacity and performance.

Nutanix currentlydoes not support mixed hypervisors(e.g., combining AHV with ESXi) within the same cluster, even for storage-only nodes.

Clarifications:

A & B:Neither Nutanix Files nor Objects are required for adding storage-only nodes.

D:Cross-hypervisor configuration is unsupported at the cluster level.

Official Reference:

Nutanix Hardware Administration Guide – Storage-Only Node Requirements

Excerpt: “All nodes in a cluster, including storage-only nodes, must run the same hypervisor type.”
