Nutanix Exam Data Analysis & Reporting 5 — Questions and Answers
Question 1: When Prism Central displays an 'Alert' versus a 'Warning' for a performance metric, what is the key distinction in severity?
- Warnings are for storage issues only; alerts are for compute issues
- Warnings indicate approaching thresholds requiring attention; alerts indicate thresholds already breached requiring immediate action (Correct answer)
- Alerts are auto-resolved; warnings require manual acknowledgment
- There is no difference — they are used interchangeably
Correct answer: Warnings indicate approaching thresholds requiring attention; alerts indicate thresholds already breached requiring immediate action
In Prism Central, warnings flag conditions approaching critical thresholds, while alerts indicate conditions that have exceeded thresholds and require immediate intervention.
Question 2: Which Nutanix API endpoint would a developer use to programmatically retrieve cluster performance metrics for integration with a third-party monitoring platform?
- Prism Element REST API v2 /cluster/stats (Correct answer)
- NCLI batch export command
- NCC REST API /health/metrics
- Calm v3 API /apps/metrics
Correct answer: Prism Element REST API v2 /cluster/stats
Prism Element's REST API v2 exposes the /cluster/stats endpoint for retrieving performance statistics programmatically for external monitoring integration.
Question 3: In a Nutanix cluster with RF2, if one node fails, how does this event appear in Prism's Data Resiliency reporting?
- The cluster is marked as 'Critical' and shuts down all VMs
- Data Resiliency Status changes to 'At Risk' — the cluster can still operate but cannot tolerate another failure (Correct answer)
- No impact is shown until a second node fails
- The report shows 'Degraded' with a countdown to automatic rebuild completion
Correct answer: Data Resiliency Status changes to 'At Risk' — the cluster can still operate but cannot tolerate another failure
With RF2, losing one node leaves the cluster with zero fault tolerance remaining, so Prism marks Data Resiliency as 'At Risk' even though the cluster continues operating.
Question 4: What is the role of 'Pulse' in Nutanix data reporting and analytics?
- A real-time dashboard widget showing heartbeat metrics
- A telemetry service that sends anonymized cluster health and performance data to Nutanix support for proactive analysis (Correct answer)
- A log aggregation tool for AHV hypervisor events
- An API gateway for third-party analytics integrations
Correct answer: A telemetry service that sends anonymized cluster health and performance data to Nutanix support for proactive analysis
Nutanix Pulse is a telemetry service that collects anonymized cluster data and sends it to Nutanix, enabling proactive support and X-Ray benchmarking insights.
Question 5: An administrator reviews a Prism analysis chart and notices VM 'Read Source' is predominantly showing 'SSD' rather than 'DRAM'. What does this most likely indicate?
- The DRAM cache is healthy and fully utilized
- The working set exceeds the DRAM cache capacity, falling back to the SSD tier (Correct answer)
- Compression is disabled on the storage container
- The VM is performing mostly write operations
Correct answer: The working set exceeds the DRAM cache capacity, falling back to the SSD tier
When reads are served from SSD rather than DRAM, it indicates the hot dataset is larger than the DRAM cache, causing cache misses that fall back to the SSD tier.
Question 6: Which Nutanix report helps identify which hosts in a cluster are most heavily utilized to support workload rebalancing decisions?
- Data Resiliency Report
- Host Performance Summary Report (Correct answer)
- Protection Domain Status Report
- Erasure Coding Efficiency Report
Correct answer: Host Performance Summary Report
The Host Performance Summary Report shows per-host CPU, memory, and storage utilization, helping administrators identify hotspots for workload rebalancing.
Question 7: In Nutanix Prism Central, which built-in capability allows administrators to set thresholds that trigger automated remediation actions when performance metrics are breached?
- NCC Alert Policies only
- Prism Pro X-Play (Playbooks) with metric-based triggers (Correct answer)
- Calm Runbooks for alerting
- Flow Policy Enforcement Engine
Correct answer: Prism Pro X-Play (Playbooks) with metric-based triggers
Prism Pro X-Play (Playbooks) enables event-driven automation where metric threshold alerts can trigger automated remediation actions such as VM scaling or ticket creation.
