The advent of our NCA-7.5 study guide with three versions has helped more than 98 percent of exam candidates get the certificate successfully. Rather than insulating from the requirements of the NCA-7.5 real exam, our NCA-7.5 practice materials closely co-related with it. And their degree of customerโs satisfaction is escalating. Besides, many exam candidates are looking forward to the advent of new NCA-7.5 versions in the future.
NEW QUESTION # 62
An administrator attempts to run a specific Nutanix Cluster Check (NCC) plugin from the Controller VM command line, but the check will not execute. The administrator discovers that this specific check was recently disabled by another user in the Prism web console.
Which action must the administrator take to successfully run this check from the command line?
Answer: C
Explanation:
When an NCC plugin has been administratively disabled, a normal command-line execution respects that disabled state and skips the plugin. To run that specific check without permanently changing its configured status in Prism, the administrator must append the --force_run=True argument to the NCC command. The flag instructs NCC to execute the selected plugin despite its disabled configuration.
Restarting the cluster health service does not change the plugin's enablement state and introduces an unnecessary service operation. Re-enabling the check in Prism Element could also permit execution, but it changes the persistent configuration and is not required when the objective is to run the check once from the command line. Running ncc health_checks run_all does not override the disabled state; the disabled plugin can still be omitted from the complete check set.
NCC supports running complete check groups, individual plugins, and command options that modify execution behavior. Administrators should use forced execution deliberately because a check may have been disabled due to environmental applicability, a known issue, or support guidance. Reference: NCC 5.2 - NCC Usage .

NEW QUESTION # 63
Before physically removing a failing disk from a Nutanix node, what step must be completed in Prism Element?
Answer: C
Explanation:
The disk must first be logically removed from the cluster through Prism Element. The administrator selects the disk, clicks Remove Disk and confirms the action. AOS then migrates any recoverable data away from the device and updates the cluster's storage metadata. The disk must not be physically removed until the process completes and the disk indicator in the hardware diagram turns red.
The red indicator confirms that AOS has finished the supported logical-removal workflow and that the disk is no longer participating as an active storage device. Physically extracting a disk before this state is reached can interrupt data migration, generate additional alerts and reduce cluster resiliency.
The cluster destroy command would destroy the cluster configuration and is entirely inappropriate for component replacement. Shutting down the CVM would unnecessarily remove storage-controller services from the node and can interfere with the evacuation process. Rebooting the AHV host neither removes the disk from AOS metadata nor confirms that data migration has completed.

NEW QUESTION # 64
An administrator is provisioning a new Linux virtual machine.
Which timezone is recommended for this VM?
Answer: D
Explanation:
UTC is the recommended timezone selection when creating a Linux VM on AHV. Nutanix specifically states that the real-time clock of a Linux VM must operate in UTC. Selecting the UTC timezone ensures that the guest's hardware-clock interpretation is consistent with Linux conventions and avoids time shifts caused by local timezone or daylight-saving changes.
Time consistency is essential for authentication, application logging, distributed databases, monitoring, certificate validation and event correlation. The guest operating system can still display a regional timezone to users at the application or operating-system level while maintaining its underlying hardware clock in UTC.
"Local" can cause the guest to interpret the virtual hardware clock according to a regional offset, producing incorrect timestamps after migration, reboot or daylight-saving transitions. "Cluster" is not a supported timezone designation for this VM setting. RTC means real-time clock and describes the clock mechanism rather than a selectable geographic timezone.
The VM should also use a reliable NTP source after deployment so its operating-system time remains synchronized.

NEW QUESTION # 65
A volume group is a collection of which components?
Answer: A
Explanation:
A Nutanix volume group is a collection of logically related virtual disks, also described as vDisks or volumes.
The group provides block-storage resources that can be attached directly to guest VMs or presented through iSCSI to supported consumers. Grouping the disks allows them to be administered, attached, protected, cloned, and managed as a related storage entity.
A storage pool aggregates physical storage capacity contributed by cluster nodes. Storage containers are logical subdivisions created within a storage pool and hold virtual disks. Consequently, a volume group can use vDisks created on Nutanix storage, but it is not a collection of pools or containers. Controller VMs run the distributed storage and cluster services on individual nodes and are unrelated to volume-group membership.
Each volume group has its own name and UUID, and administrators can add or remove virtual disks according to platform limitations. A group may be associated with one or more consumers depending on the attachment mode and supported use case. This structure is particularly suitable for applications requiring shared block devices, direct iSCSI access, or multiple related application volumes. References: Prism - Volume Group Configuration and Prism Central - Storage Components . NHCF alignment: volume groups and block-storage operations.
NEW QUESTION # 66
LCM provides which two features for firmware and software updates? (Choose two.)
Answer: C,D
Explanation:
Life Cycle Manager provides automatic dependency management and a one-click update workflow for supported Nutanix software and hardware firmware. LCM inventories the environment, identifies installed component versions, retrieves compatible update metadata, and evaluates dependencies between components before permitting an upgrade. This prevents administrators from manually determining the correct order for related AOS, AHV, NCC, Foundation, firmware, and platform updates.
Nutanix describes the LCM workflow as a one-click update because administrators can select eligible components and initiate an orchestrated upgrade through Prism. LCM then performs prechecks, stages packages, applies updates in the necessary sequence, and coordinates node maintenance while preserving cluster availability where supported.
A general rollback to the previous software or firmware version is not an LCM feature. Upgrades should therefore be treated as forward-moving maintenance operations that require validated backups, health checks, and compatibility review. Although LCM supports numerous qualified hardware platforms, option C is not the core feature being tested. Platform support depends on the hardware vendor, model, firmware bundle, and Nutanix compatibility requirements; it is not an unrestricted multi-platform update function.
