NCP Monitoring, Maintenance, and Troubleshooting 5

Question 1

A Nutanix cluster running RF2 loses two nodes simultaneously. What is the expected impact?

Accepted Answer

All VMs are shut down and data becomes inaccessible

Answer

With RF2, the cluster can tolerate only one node failure; losing two nodes simultaneously results in loss of quorum and data unavailability.

Question 2

Which Prism Central feature allows administrators to set automated actions when a specific alert is triggered, such as running a script?

Accepted Answer

Playbooks

Answer

Prism Central Playbooks allow administrators to define trigger-action automations, including running scripts or REST API calls in response to alerts.

Question 3

An administrator needs to verify that Nutanix software-defined storage is not contributing to application latency. Which metric should be monitored in Prism?

Accepted Answer

Controller Average I/O Latency

Answer

Controller Average I/O Latency measures the latency at the Nutanix storage controller layer, isolating storage as a latency contributor.

Question 4

When troubleshooting a failed NCC check for 'cluster_services_status_check', which CVM command provides the quickest status overview of all Nutanix services?

Accepted Answer

allssh genesis status

Answer

Running 'allssh genesis status' executes genesis status across all CVMs simultaneously, giving a quick cluster-wide service health overview.

Question 5

A Nutanix administrator wants to schedule a one-time full NCC health check to run during off-peak hours. How is this accomplished?

Accepted Answer

Configure a Prism Central Playbook to trigger NCC at a specific time
