Nutanix Exam Quality Assurance & Improvement 2 — Questions and Answers
Question 1: Which Nutanix tool provides continuous health monitoring and proactive diagnostics for a cluster?
- Prism Central Alerts
- Nutanix Pulse
- LCM (Life Cycle Manager)
- NCC (Nutanix Cluster Check) (Correct answer)
Correct answer: NCC (Nutanix Cluster Check)
NCC runs hundreds of health checks across cluster components to proactively identify issues before they cause outages.
Question 2: What does a 'WARNING' severity NCC check result typically indicate?
- The cluster has failed and requires immediate shutdown
- A condition exists that may lead to a problem if not addressed (Correct answer)
- The check could not complete due to missing credentials
- The component is operating within optimal parameters
Correct answer: A condition exists that may lead to a problem if not addressed
WARNING results flag sub-optimal conditions that are not yet critical but should be remediated to avoid future failures.
Question 3: In Nutanix, what is the primary purpose of Prism Pro's Capacity Runway feature?
- To forecast when cluster resources will be exhausted based on historical trends (Correct answer)
- To automatically provision new nodes when utilization exceeds 80%
- To throttle VM workloads to prevent resource contention
- To generate compliance reports for audit purposes
Correct answer: To forecast when cluster resources will be exhausted based on historical trends
Capacity Runway uses historical consumption trends to predict how many days remain before CPU, memory, or storage runs out.
Question 4: Which metric is most critical to monitor when assessing storage performance quality on a Nutanix cluster?
- vDisk count per storage container
- Average I/O latency at the controller VM level (Correct answer)
- Number of snapshots per VM
- Storage container deduplication savings ratio
Correct answer: Average I/O latency at the controller VM level
Controller VM I/O latency directly reflects storage performance quality and is the primary indicator of whether VMs are experiencing delays.
Question 5: What action should be taken when an NCC check reports a 'FAIL' for a disk in a degraded state?
- Immediately delete all VMs on that node
- Acknowledge the alert and monitor for 48 hours before acting
- Engage Nutanix Support and prepare for disk replacement (Correct answer)
- Disable the storage tier that contains the disk
Correct answer: Engage Nutanix Support and prepare for disk replacement
A FAIL on a degraded disk indicates hardware risk; Nutanix Support should be engaged immediately to coordinate disk replacement before data loss.
Question 6: Which Nutanix feature automatically re-protects data when a drive failure occurs?
- Erasure Coding rebuild
- Data resiliency self-healing via Curator (Correct answer)
- Prism Central auto-recovery policy
- AOS snapshot rollback
Correct answer: Data resiliency self-healing via Curator
Curator, the distributed metadata manager, detects under-replicated data after a drive failure and automatically re-replicates it to restore resiliency.
Question 7: What is the recommended approach to validate cluster health before performing a major AOS upgrade?
- Run a full NCC health check and resolve any WARN or FAIL items (Correct answer)
- Snapshot all VMs and pause replication schedules
- Disable Pulse telemetry to prevent false alerts during upgrade
- Manually verify each CVM's CPU and memory utilization
Correct answer: Run a full NCC health check and resolve any WARN or FAIL items
Nutanix best practice requires a clean NCC run with no unresolved WARN/FAIL results before initiating any major upgrade.
