NCP-MCI-6.10 Exam Dumps - Nutanix NCM-MCI Questions and Answers

When creating templates in Nutanix, Prism Central supports two official, built-in guest customization frameworks depending on the operating system family.

The Nutanix guest customization documentation states:

“For Windows VMs, Prism Central supports Sysprep-based customization. For Linux VMs, Prism Central supports Cloud-init customization.”

These two tools allow automation of hostname assignment, networking configuration, user accounts, and post-deployment initialization.

Additional extracts from internal documentation:

“Sysprep is automatically invoked during clone operations from Windows templates to ensure that the cloned VM receives unique identifiers.”

“Cloud-init is used for Linux templates to allow dynamic provisioning, SSH key injection, and package installation during instantiation.”

Nutanix does not list “Custom Script” or “Guided Script” as valid VM template customization mechanisms. Scripting can be applied after deployment but not as a built-in template customization framework.

Thus, the only valid template customization options are Sysprep and Cloud-init.

Nutanix performance troubleshooting guidelines emphasize the importance of adequate vCPU resources when diagnosing single-VM performance issues. The documentation states that “under-provisioned CPU is a primary cause of perceived storage latency and throughput limitations, as storage I/O processing and VirtIO-SCSI operations depend heavily on VM compute resources.”

Running a Windows Server VM with only one vCPU significantly constrains its ability to queue and process disk I/O, handle interrupts, and run kernel-level services. This is especially true when multiple disks are attached. Adding a second controller does not solve underlying CPU bottlenecks. Adjusting br0 TCP settings is not applicable to storage. Increasing CVM resources is unnecessary because the problem is isolated to a single VM while the cluster and other VMs perform normally.

Therefore, increasing vCPU allocation is the required corrective action.

When synchronous replication has been configured and a planned failover is required for datacenter maintenance, Nutanix recommends performing aplanned failoverto ensure data consistency and a clean transition of services.

From theNutanix 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.

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.
