NCP Virtual Machine Management 5 — Questions and Answers
Question 1: Which Nutanix feature provides self-service VM restoration from snapshots directly by end users without admin intervention?
- Prism Self-Service Portal
- NGT Self-Service Restore (SSR) (Correct answer)
- Calm Runbooks
- Protection Domain User Access
Correct answer: NGT Self-Service Restore (SSR)
NGT's Self-Service Restore (SSR) allows end users to browse and restore individual files or entire VMs from snapshots without requiring administrator assistance.
Question 2: When configuring VM boot settings in AHV, which boot firmware type is required to support Secure Boot?
- BIOS (Legacy)
- UEFI (Correct answer)
- PXE Boot
- ACPI Boot
Correct answer: UEFI
UEFI firmware must be selected in the VM's boot settings to enable Secure Boot, which verifies bootloader and OS integrity during startup.
Question 3: In a Nutanix cluster, what is the purpose of the 'Recycle Bin' for VMs in Prism?
- Stores deleted VMs temporarily for recovery before permanent deletion (Correct answer)
- Archives powered-off VMs to cold storage automatically
- Holds VMs that failed HA failover
- Quarantines VMs flagged by Flow Security
Correct answer: Stores deleted VMs temporarily for recovery before permanent deletion
The Prism Recycle Bin temporarily retains deleted VMs for a configurable period, allowing administrators to recover accidentally deleted VMs.
Question 4: What is the significance of a VM's 'UUID' in Nutanix AHV management?
- It determines the VM's storage tier assignment
- It is a globally unique identifier used to track and manage the VM across operations (Correct answer)
- It specifies the VM's network VLAN assignment
- It controls the VM's CPU scheduling priority
Correct answer: It is a globally unique identifier used to track and manage the VM across operations
A VM's UUID is its unique identifier within the Nutanix cluster, used by APIs, scripts, and internal systems to reference and manage the specific VM.
Question 5: Which AHV feature allows administrators to limit the impact of a noisy VM on shared storage resources by capping its IOPS?
- VM Affinity Rules
- Disk I/O Throttling (Storage QoS) (Correct answer)
- Erasure Coding Policy
- CVM Storage Reservations
Correct answer: Disk I/O Throttling (Storage QoS)
Storage QoS (Disk I/O Throttling) allows administrators to set IOPS limits on individual VM vDisks, preventing any single VM from monopolizing shared storage.
Question 6: When a VM is migrated between hosts during AHV maintenance mode, what is preserved throughout the migration?
- Only the VM's disk data
- The VM's running state, memory contents, and network connections (Correct answer)
- Only the VM's CPU state
- The VM's snapshot history but not its running state
Correct answer: The VM's running state, memory contents, and network connections
AHV live migration preserves the complete running state of a VM including memory contents and active network connections, ensuring continuity of service.
Question 7: In Nutanix Prism Central, which feature allows you to apply consistent VM management policies across multiple clusters from a single interface?
- Cluster-Specific Policy Assignment
- Categories and Policies (via entity tagging) (Correct answer)
- Per-Host Configuration Templates
- Individual Cluster Policy Sync
Correct answer: Categories and Policies (via entity tagging)
Prism Central's Categories feature allows you to tag VMs with logical labels, then apply security, protection, and other policies to all VMs sharing a category across multiple clusters.
