NCP Virtual Machine Management 3 — Questions and Answers
Question 1: Which Nutanix feature enables you to deploy VMs from pre-configured templates with standardized settings?
- VM Snapshots
- Image Service
- Calm Blueprints
- VM Templates (Correct answer)
Correct answer: VM Templates
VM Templates in Nutanix allow administrators to create standardized VM configurations that can be rapidly deployed as new VMs.
Question 2: When cloning a VM in Nutanix, which storage optimization technique ensures clones share unchanged data blocks with the parent?
- Erasure Coding
- Deduplication
- Linked Clone / Redirect-on-Write (Correct answer)
- Compression
Correct answer: Linked Clone / Redirect-on-Write
Nutanix uses a redirect-on-write mechanism for VM clones, where clones share unchanged data blocks with the parent and only write new blocks when data changes.
Question 3: What is the recommended way to gracefully shut down a VM in Nutanix Prism to ensure data integrity?
- Use the 'Power Off' action from Prism
- Issue a guest OS shutdown from within the VM (Correct answer)
- Use 'Force Power Off' from Prism
- Delete the VM's vDisk to force shutdown
Correct answer: Issue a guest OS shutdown from within the VM
Issuing a graceful shutdown from within the guest OS (or using Prism's 'Guest Shutdown' with NGT installed) ensures OS-level flushing and data integrity.
Question 4: Which Nutanix Guest Tools (NGT) capability enables in-guest consistent snapshots for applications like databases?
- VSS integration
- Application-Consistent Snapshots (Correct answer)
- File-Level Restore
- Self-Service Restore
Correct answer: Application-Consistent Snapshots
NGT's application-consistent snapshot feature uses VSS on Windows to quiesce applications before snapshots, ensuring database and application consistency.
Question 5: In AHV, what determines which physical host a VM is initially placed on during power-on?
- Storage Controller VM availability
- AHV Scheduler (based on resource availability and affinity rules) (Correct answer)
- The order in which hosts were added to the cluster
- Manual administrator selection only
Correct answer: AHV Scheduler (based on resource availability and affinity rules)
The AHV Scheduler evaluates available CPU, memory, and defined affinity/anti-affinity rules to optimally place a VM when it is powered on.
Question 6: What is the maximum number of virtual NICs (vNICs) that can be attached to a single VM in AHV?
- 4
- 8 (Correct answer)
- 16
- 32
Correct answer: 8
AHV supports attaching up to 8 virtual NICs to a single VM, allowing for complex multi-network configurations.
Question 7: When a Nutanix node hosting running VMs fails, what mechanism automatically restarts those VMs on surviving nodes?
- Nutanix Calm
- High Availability (HA) Failover (Correct answer)
- Protection Domain Replication
- Disaster Recovery Failover
Correct answer: High Availability (HA) Failover
AHV High Availability automatically detects node failure and restarts affected VMs on remaining healthy nodes in the cluster.
