NCS-Core Exam Dumps : Nutanix Certified Services Core Infrastructure Professional (NCS-Core 6.8)

For creating a Disaster Recovery Test plan for Nutanix environments, verifying that VMs receive the correct IP address after a failover is critical to validate VM availability across the network. This check is essential to ensure that network configurations and DHCP/Static IP settings are correctly applied post-failover, enabling proper network communications and access to services hosted on the VMs. Ensuring correct IP addressing is fundamental to the successful operation of DR strategies in virtualized environments.References: Nutanix Disaster Recovery Best Practices, Nutanix Network Configuration for DR environments.

Given the reported RX errors on eth2 and the intermittent ping loss as observed from the CVM logs, the best initial troubleshooting step that avoids VM disruption is to inspect the switch port for errors. Option C, "Check the port on the switch side for any errors," is the most direct and non-invasive approach to determining if the issue lies with the network infrastructure rather than the server hardware itself or the configuration.

This action helps identify whether the problem is related to the physical connection (e.g., port issues, switch configuration errors) without altering the current active network setup on the Nutanix node. If errors are found on the switch port, adjustments or repairs can be made accordingly, potentially resolving the RX errors without impacting the running VMs.

To address critical alerts about components using default passwords in the Prism Element Web Console:

• C. Check NCC results and review the associated KB: The Nutanix Cluster Check (NCC) tool can identify security vulnerabilities, including default password usage. Reviewing the results and associated knowledge base articles provides specific guidance on changing these passwords to secure the environment.
