NCS Professional NCS-Core Nutanix Study Notes

The alert for Protection Policy PP-BCA-1HR indicating critical availability issues is most likely due to the workloads included in the policy no longer meeting their intended Recovery Point Objective (RPO). A 1-hour snapshot frequency implies a stringent RPO, which if not maintained, could result in data loss beyond acceptable business limits. This scenario typically generates a critical alert in Prism Central, especially when the snapshots required to meet the RPO are not completed as scheduled due to any number of issues such as resource constraints or network issues.References: Nutanix Prism User Guide, Nutanix Data Protection Best Practices.

An alert of this nature in the file server dashboard usually indicates issues related to node availability within a cluster. Specifically, the failure of a node in a three-node cluster (Option B) can lead to insufficient resources to handle all tasks, which might trigger such an alert. Additionally, setting a node to maintenance mode in a three-node cluster (Option D) also disrupts service availability and could generate a similar alert, as the remaining nodes might struggle to handle the load or maintain data redundancy.References: Nutanix AOS User Guide, Nutanix Files Documentation.

The document that needs to be completed with the customer to collect configuration items such as IP addresses, Gateway, DNS servers, and NTP Servers is the Technical Checklist. This checklist is designed to ensure all necessary technical information is gathered prior to the installation, enabling a smooth and efficient setup process.References: Nutanix Cluster Deployment Guide, Pre-installation Planning Documentation.

In the scenario where a consultant is viewing an ESXi host via console without external network connectivity and needs to connect to the Controller Virtual Machine (CVM), the typical IP addresses used for such connections in a Nutanix environment are in the 192.168.5.x range. Specifically, the IP addresses for CVMs often set by default or during initial configuration, such as 192.168.5.253 and 192.168.5.254 (Options A and C), can be used. These addresses are generally reserved for internal CVM communications and can be accessed through the host's internal network configurations.References: Nutanix Cluster Installation Guide, Default Nutanix Network Configurations.
